New Feature in technology HDMI V.1.4



Technology HDMI 1.4 cables now could make you transfer Internet data in the same cable when currently transfers only video and audio data. with this solves problems for people who have an awful time connecting devices to the web and each other in the living room. I use powerline Internet adapters, which connect my DSL broadband line to my living room via power sockets. Wireless doesn’t work so well in my home. So right now, you have to switch cables from one game console to another whenever you use them. It’s a hassle.

HDMI connects devices such as Blu-ray player to a TV set with no loss in the high-definition video quality. All new TVs have the HDMI connectors, as do many other video appliances. HDMI is keeping up with the times. About 24 percent of all consumer electronics devices will require Ethernet in 2009. With more devices connected to the Internet, this new connector means that you will be able to access your content via the Internet on more of your future home devices. The Ethernet connection enables a variety of new applications, such as the ability to play a video on a Blu-ray player on any web-connected TV in your home.

Audio Return Channel so you can connect your stereo to your TV and have it play music on your TV set, even as you get rid of a cable. And HDMI 1.4 has Automatic Content Enhancement, which optimizes the settings on your TV to fit whatever movie or video you’re playing. It also has 3-D support and support for higher resolution video of 4,000 x 2,000 pixels. And another new feature is a complete color palette that allows you to connect almost any HD digital still camera and show the pictures with the highest viewing quality on your TV. Sometimes TVs don’t have the breadth of color to display still pictures well.

one more another feature is the Micro HDMI connector. This connector is about the size of a mini universal serial bus (USB) connector. It can likely be built into cell phones in the future to let you play back high-definition video recorded with a cell phone camera on a TV. I recently saw a demonstration of that at Broadcom’s offices in Sunnyvale, Calif. It looked pretty cool.

Microsoft Surface : the new Generation of multi touch Computer



Microsoft Surface is more than a computer. It’s a leap ahead in digital interaction. By enabling you to use your hands instead of a keyboard and mouse, it revolutionizes the way you interact with digital content, while keeping the ability to connect with other devices such as networks, printers, mobile devices, card readers, and more. Our Microsoft Surface Partners have created hundreds of applications for the platform.

Microsoft Surface is currently based on the Windows Vista platform, which makes it especially easy for companies to manage, deploy and support Microsoft Surface units. The current version for the software platform is Microsoft Surface 1.0 Service Pack 1, which enhances Surface with an enhanced user interface, improved manageability to help reduce the cost of ownership, broader international support, and faster, easier ways to design innovative applications. Read more about Service Pack 1 on the Microsoft Surface Blog.

The sophisticated camera system of Surface sees what is touching it and recognizes fingers, hands, paintbrushes, tagged objects and a myriad of other real-world items. It allows you to grab digital information and interact with the content through touch and gesture. And unlike other touch-screens, Surface recognizes many points of contact simultaneously, 52 to be exact. This allows multiple people to use Surface at the same time, creating a more engaging and collaborative computing experience than what is available via traditional personal computers, mobile devices, or public kiosks.

Tagged object recognition is a particularly innovative feature of Microsoft Surface. The tag is what lets Surface uniquely identify objects, helping the system tell the difference between two identical looking bottles of juice, for example. Applications can also use a tag to start a command or action, so simply placing a tagged object on the screen can open up a whole new experience. A tagged object might also identify a cardholder, so they can charge purchases or participate in a loyalty program. A tag can even tell Surface to display unique information about a tagged object, such as showing more information about a bottle of wine, the wine grower, the type of grape and vintage.

a Microsoft Surface unit is a PC that is running the Windows Vista Business operating system, so in some ways, a Surface unit is like a desktop computer or a server. The units include all of the standard manageability features that are available in Windows Vista to enable easy deployment and administration, including Windows Management Instrumentation (WMI), Remote Desktop Connection, Windows Scripting Host, Event Viewer, Performance Monitor, Event Forwarding, Task Scheduler, and so on. You can also use enterprise management tools like the Microsoft System Center family of products to deploy software, maintain patches, manage configuration, and monitor health.

You can also deploy Microsoft Surface units to remote locations away from the immediate reach of an IT administrator and then use remote management tools and scripting to accomplish administration tasks, such as taking a unit offline, installing applications, monitoring the unit, managing updates, and recovering the system.
Microsoft Surface represents a fundamental change in the way we interact with digital content. Leave the mouse and keyboard behind. Surface lets you grab digital content with your hands and move information with simple gestures and touches. Surface also sees and interacts with objects placed on the screen, allowing you to move information between devices like mobile phones or cameras. The result is a fun, social and exciting computing experience like you’ve never had before.

Microsoft Surface has four key capabilities that make it such a unique experience:

* Direct interaction. Users can grab digital information with their hands and interact with content on-screen by touch and gesture – without using a mouse or keyboard.
* Multi-user experience. The large, horizontal, 30 inch display makes it easy for several people to gather and interact together with Microsoft Surface - providing a collaborative, face-to-face computing experience.
* Multi-touch. Microsoft Surface responds to many points of contact simultaneously - not just from one finger, as with a typical touch screen, but from dozens of contact points at once.
* Object recognition. Users can place physical objects on the screen to trigger different types of digital responses – providing for a multitude of applications and the transfer of digital content to mobile devices.

Microsoft Surface uses cameras and image recognition in the infrared spectrum to recognize different types of objects such as fingers, tagged items and shapes. This input is then processed by the computer and the resulting interaction is displayed using rear projection. The user can manipulate content and interact with the computer using natural touch and hand gestures, instead of a typical mouse and keyboard.

VoIP System Standart Features

Voice over IP (VoIP) systems today are gaining in popularity today for several reasons, most notable are the availability of so many open source and commercial options, the high degree of available interface devices that allow you to connect to existing circuit based networks and hardware, and the ability to create full end to end IP based solutions using available high-speed links or gateways with commercial trunk providers. However, it is still easy to make a poor purchasing decision unless you take a good look at the basic requirements of what a communication system needs to provide to be effective in your business and help you achieve your cost savings while still maintaining your ability to be connected to your clients and vendors in an effective manner. My intent here is to help outline the 5 standard features that your VoIP system should have for it to be considered the proper solution for your enterprise.

Examination

Standardization and Flexibility

Just like Henry Ford grew the automobile business based upon the obvious concept of standardization, the VoIP industry gained its recent focus and popularity based upon the same ideals. Gone are the days of having to select and architect a solution based upon the supported protocols of one vendor and become locked in. The two major signaling protocols you will see today, H.323 and SIP are the largest players, with H.323 starting to lag behind as SIP gains in popularity and support, more compliant vendors, and continued enhanced to support more media streams and tighter device integration that up until recently has been what was keeping H.323 ahead in the game. Keeping in mind that H.323 is still the more mature technology, currently it is holding its ground in the carrier space and is used quite extensively as a trunk side protocol. This has allowed SIP to comfortably gain foothold in the enterprise space as a local carrier style protocol that is simpler to implement, troubleshoot, and extend with new features as needed. It is clear that for a system to be considered future proof it has to support the currently prevalent standards but also allow ‘plug ability’ and offer support for emerging standards, or alterations to the existing standards as well.

Integration Options

Unless you are starting from scratch you are most likely attempting to integrate a VoIP option into your existing infrastructure as part of a phased deployment strategy. The current list of options to accomplish this is growing longer and longer every day, and that has many benefits for the consumer with regards to architecture, cost, interoperability options, and the quicker movement to tighter standards compliance between vendors. There is no longer a need to consider the move to VoIP to be an all or nothing deal with the introduction of gateway devices that allow you to leverage your current investment in older TDM based equipment and enhance it with the newer IP based messaging solutions. Doing this allows you to add new devices to the newer IP network while maintaining a rich level of integration with the legacy TDM equipment until it lives out its natural (and still depreciable) life span.

Security

As with everything today, security is a huge consideration when you start to think about moving to VoIP. If it is not something that you have already though about, or your vendor has not discussed it deeply with you then I urge you to stop reading this right now, go to your vendor and ASK how secure your current VoIP implementation (or the one you are planning to install) is.

Security is so critical in today’s business market, but because people have felt so safe in the past using TDM voice infrastructures where ‘tapping’ meant actually making a physical connection to the ‘wires’, the thought of security quite often eludes people when you starting the talk about VoIP. It is so easy to fire up a copy of Wireshark on your network, collect some packets, and use the tools built right into the GUI to listen to VoIP conversations. So, what do you do? The answer is simple. You turn on encryption and ensure that every device you use within in your IP infrastructure involved in the call supports the encryption scheme that you pick. Keep in mind that while encryption is good, it does add CPU load to your devices, can cause higher network utilization because the packets can get larger, and can add complexity to any troubleshooting efforts, but you should NOT implement any VoIP system without taking security into consideration. One fine option that I have used is to consider your internal network to be secure and just encrypt the calls that pass via IP between external parties (over your IP based trunks if you use them) or between all your company locations using the public IP network. It’s my feeling that as long as you keep your internal IP infrastructure secure (IE: tight controls on who can enter your IT area, and you are using switches rather than hubs), bothering to encrypt internal IP connections is not always needed because in a properly configured environment you will not be able to capture VoIP data other than what is directed to you. If you are using hubs then all bets are off of course. That is a subject for another article.

Support

As with most other technologies, part of your purchasing and deployment planning MUST be to take the support model into consideration. Don’t just assume that your existing vendor that supports your current internet connection to the external world is going to be there if you have IP trunk problems, understand what terminology like QoS, jitter, and other VoIP lingo means, or even how to correct them if problems occur. As when introducing any new technology you need to have a sit-down with everyone involved in the proposed value chain and establish an understanding of expectations, possible support needs, costs, and schedules. You may find out that your provider is by default blocking the native ports that the typical VoIP protocols require simply because they are not used to requiring them to be open for other clients. If you are ready to move to IP for your voice communications just understand that while you may have been willing to put up with slowness in the afternoons when you tried to use the web to order your dinner so you could pick it up on the way home, a slow data connection can wreak havoc with voice quality and the ability to establish a call. You may need to consider a separate IP connection just dedicated to voice, and in fact you may need to start considering redundant connections using two different providers for your voice if you have not already done so for your data. Additionally, ensure that your vendor has the proper debugging tools in place, knows how to use them, and is willing to offer training to your staff, or that you are willing to use third parties to get them trained, so that they can be used to keep the system running in top condition. Remember that voice communication is still considered a top priority in today’s business world and loosing that, even for a few hours, can make a customer start looking for someone to replace you as a vendor.

Extension Points

Many people today are used to just using the phone to talk, or maybe send faxes, but once the move to IP is made the benefits will start to bring on questions about other methods of application integration, and additional ways to leverage the new communications system. One thing that you should always consider on any new system, not just VoIP, are ways that you can utilize it going forward for things other than just your current needs. A car would not be much use if you could only drive it back and forth to work would it? The same goes for your telephony solution. Right from the start you should consider investigating the extension areas of all the solutions you look at and at least gain an understanding of the features and benefits that each system may or may not offer. For example, it could be very disappointing to get a system all in place and six months latter determine that you still need to add a bank of analog trunk lines to and receive faxes because your solution did not include the ability for Fax over IP (FoIP) codecs. Making blanket assumptions like ‘just because traditional faxes use our existing voice lines the VoIP system should also do fax’ can lead to some very tense moments across a boardroom table. Also consider integration with other areas like Instant Messaging (IM) and application integration such as the ability to build basic Interactive Voice Response (IVR) menus (IE: ‘To talk to support, please press 1, to talk to sales, please press 2,…) into the system and create simple auto attendant applications. These simple features can help add some great value that may not have been considered previously, and allow you to recoup the costs of a VoIP implementation over a shorter timeline than previously anticipated. Areas like this can allow you to bring systems together under one area and thus cut down the size of your external vendor list.
Conclusion

As you can see, the move to VoIP is fraught with decisions, technical considerations, and even some simple human capital management opportunities, but the gains in productivity, efficiency, and the ability to leverage existing infrastructure and gain some valuable benefits in the areas of long term manageability, application integration, multi-modal communications options and simpler to manage infrastructure far outweigh the potential problems as long as the map forward is well thought out and planned. As with most IT based business decisions it is always good to ensure that everyone understands the possible features and benefits as well as the potential risks and how they can be mitigated to derive the value that is expected.

Disclosures and References

As part of my previous experience in VoIP technology I spent 10 years as a product and training specialist working for both Intel Corporation and Dialogic Corporation in the area of Digital PBX TDM to IP interfacing with regards to the Netstructure PBX/IP Media gateway product line. In addition, my secondary focus was working closely with vendors offering tightly integrated VoIP solutions such as Microsoft Exchnage Unified Messaging and IBM Lotus Sametime using these devices as well as the design and development of product training classes, certification programs for user and administrative positions, and product documentation collateral.

VDSL, Improvement of Internet Speed

VDSL/VHDSL (Very High Bitrate Digital Subscriber Line) is an improved version of the technology, ADSL or Asymmetric Digital Subscriber Line, which we use to connect to the internet. They are different in how they are implemented so you probably cannot use the equipment of one for the other. The most significant difference between the two technologies that is most relevant to the use is speed. ADSL can reach maximum speeds of 8mbps download and 1mbps for upload. In comparison, VDSL can have up to 52mbps for download and 16mbps for upload.

Because of the extremely high speeds that VDSL can accommodate, it is being looked at as a good prospective technology for accommodating high bandwidth applications like VoIP telephony and even HDTV transmission, which ADSL is not capable of. Another very useful feature of VDSL stems from the fact that it uses 7 different frequency bands for the transmission of data. The user then has the power to customize whether each frequency band would be used for download or upload. This kind of flexibility is very nice in case you need to host certain files that are to be downloaded by a lot of people.

The most major drawback for VDSL is the distance it needs to be from the telephone exchange. Within 300m, you may still get close to maximum speed but beyond that, the line quality and the speed deteriorates rather quickly. Because of this, ADSL is still preferable unless you live extremely close to the telephone exchange of the company that you are subscribed to. Most VDSL subscribers are companies who need a very fast server and would often place their own servers in very close proximity.

Due to the limitations of VDSL and its high price, its expansion is not as prolific as that of ADSL. VDSL is only widespread in countries like South Korea and Japan. While other countries also have VDSL offerings, it is only handled from a few companies; mostly one or two in most countries. In comparison, ADSL is very widely used and all countries that offer high speed internet offer ADSL.
DSL technology known as very high bit-rate DSL (VDSL) is seen by many as the next step in providing a complete home-communications/entertainment package. There are already some companies, such as U.S. West (part of Qwest now), that offer VDSL service in selected areas. VDSL provides an incredible amount of bandwidth, with speeds up to about 52 megabits per second (Mbps). Compare that with a maximum speed of 8 to 10 Mbps for ADSL or cable modem and it's clear that the move from current broadband technology to VDSL could be as significant as the migration from a 56K modem to broadband. As VDSL becomes more common, you can expect that integrated packages will be cheaper than the total amount for current separate services.

In this article, you'll learn about VDSL technology, why it's important and how it compares to other DSL technologies. But first, let's take a look at the basics of DSL.

A standard telephone installation in the United States consists of a pair of copper wires that the phone company installs in your home. A pair of copper wires has plenty of bandwidth for carrying data in addition to voice conversations. Voice signals use only a fraction of the available capacity on the wires. DSL exploits this remaining capacity to carry information on the wire without disturbing the line's ability to carry conversations.

Standard phone service limits the frequencies that the switches, telephones and other equipment can carry. Human voices, speaking in normal conversational tones, can be carried in a frequency range of 400 to 3,400 Hertz (cycles per second). In most cases, the wires themselves have the potential to handle frequencies of up to several-million Hertz. Modern equipment that sends digital (rather than analog) data can safely use much more of the telephone line's capacity, and DSL does just that.
VDSL could change the face of E-commerce by allowing all types of media to run smoothly and beautifully through your computer.

WiFi peer-to-peer Direct is Go

Wi-Fi Alliance on Monday announced that its direct peer-to-peer networking version of WiFi, called WiFi Direct, is now available on several new WiFi devices. The Alliance is also announcing that it has begun the process of certifying devices for WiFi Direct compatibility.

The organization has already certified a handful of WiFi cards from Atheros, Broadcom, Intel, Ralink, Realtek, and Cisco, as well as the Cisco Aironet 1240 Series access points. These devices will also be used in the test suite to certify that future devices are compatible with the protocol. Any device passing the tests will be designated "Wi-Fi CERTIFIED Wi-Fi Direct."

"We designed Wi-Fi Direct to unleash a wide variety of applications which require device connections, but do not need the internet or even a traditional network," said Edgar Figueroa, CEO of the Wi-Fi Alliance, in a statement. The certification program will ensure compatibility with the standard across a range of devices. WiFi Direct devices can also connect to older "Wi-Fi CERTIFIED" devices for backward compatibility, so chances are your current equipment will work with newer devices using the protocol.

The new protocol allows compatible devices to connect in a peer-to-peer fashion, either one-to-one or in a group, to share data with each other. The Alliance noted that many users carry a lot of data with them on portable devices like smartphones; WiFi Direct will enable users to connect these devices with each other to share that data without the need for a local WiFi network.

Though ad-hoc WiFi and Bluetooth protocols serve similar purposes, WiFi direct offers the longest range and fastest throughput, and includes enterprise-class management and security features.

Microsoft Windows Azure Future Concept

Microsoft unveiled its roadmap for the Windows Azure cloud computing platform. Moving beyond mere Infrastructure-as-a-Service (IaaS), the company is positioning Windows Azure as a Platform-as-a-Service offering: a comprehensive set of development tools, services, and management systems to allow developers to concentrate on creating available, scalable applications.

Over the next 12-18 months, a raft of new functionality will be rolled out to Windows Azure customers. These features will both make it easier to move existing applications into the cloud, and enhance the services available to cloud-hosted applications.

The company believes that putting applications into the cloud will often be a multistage process. Initially, the applications will run unmodified, which will remove patching and maintenance burdens, but not take advantage of any cloud-specific functionality. Over time, the applications will be updated and modified to start to take advantage of some of the additional capabilities that the Windows Azure platform has to offer.

Microsoft is building Windows Azure into an extremely complete cloud platform. Windows Azure currently takes quite a high-level approach to cloud services: applications have limited access to the underlying operating system, and software that requires Administrator installation isn't usable. Later in the year, Microsoft will enable Administrator-level access and Remote Desktop to Windows Azure instances.

For even more compatibility with existing applications, a new Virtual Machine role is being introduced. This will allow Windows Azure users to upload VHD virtual disks and run these virtual machines in the cloud. In a similar vein, Server Application Virtualization will allow server applications to be deployed to the cloud, without the need either to rewrite them or package them within a VHD. These features will be available in beta by the end of the year. Next year, virtual machine construction will be extended to allow the creation of virtual machines within the cloud. Initially, virtual machine roles will support Windows Server 2008 R2; in 2011, Windows Server 2003 and Windows Server 2008 with Service Pack 2 will also be supported.

Microsoft also has a lot to offer for applications that are cloud-aware. Over the past year, SQL Azure, the cloud-based SQL Server version, has moved closer to feature parity with its conventional version: this will continue with the introduction of SQL Azure Reporting, bringing SQL Server's reporting features to the cloud. New data syncing capabilities will also be introduced, allowing SQL Azure to replicate data with on-premises and mobile applications. Both of these will be available in previews by the end of the year, with final releases in 2011.

A range of new building-block technologies are also being introduced, including a caching component (similar to systems such as memcached) and a message bus (for reliable delivery of messages to and from other applications or mobile devices). A smaller, cheaper tier of Windows Azure instances is also being introduced, comparable to Amazon's recently-released Micro instances of EC2.

The breadth of services that Microsoft is building for the Windows Azure platform is substantial. Compared to Amazon's EC2 or Google's AppEngine, Windows Azure is becoming a far more complete platform: while EC2 and AppEngine both offer a few bits and pieces that are comparable (EC2 is particularly strong at hosting existing applications in custom virtual machines, for example), they aren't offering the same cohesive set of services.

Nonetheless, there are still areas that could be improved. The billing system is currently inflexible, and offers no ability for third parties to integrate with the existing Windows Azure billing. This means that a company wishing to offer its own building blocks for use by Windows Azure applications has to also implement its own monitoring and billing system. Windows Azure also has no built-in facility for automating job management and scaling.

Both of these gaps were pertinent to one of yesterday's demonstrations. Animation studio Pixar has developed a prototype version of its RenderMan rendering engine that works on Windows Azure. Traditionally, RenderMan was only accessible to the very largest animation studios, as it requires considerable investment in hardware to build render farms. By moving RenderMan to the cloud, smaller studios can use RenderMan for rendering jobs without having to maintain all those systems. It allows RenderMan to be sold as a service to anyone needing rendering capabilities.

Neither job management—choosing when to spin up extra instances, when to power them down, how to spread the different frames that need rendering between instances—nor billing are handled by Windows Azure itself. In both cases, Pixar needed to develop its own facilities. Microsoft recognizes that these are likely to be useful to a broad range of applications, and as such good candidates for a Microsoft-provided building block. But at the moment, they're not a part of the platform.

Microsoft CEO Steve Ballmer has said that Microsoft is "all in" with the cloud. The company is certainly working hard to make Windows Azure a better platform, and the commitment to the cloud extends beyond the Windows Azure team itself. Ars was told that all new development of online applications within Microsoft was using Windows Azure, and with few exceptions, existing online applications had migration plans that would be implemented in the next two years. The two notable exceptions are Hotmail and Bing, both of which already have their own, custom-built, dedicated server farms.

This internal commitment is no surprise given the history of the platform. Windows Azure was originally devised and developed to be an internal platform for application hosting. However, before there was any significant amount of internal usage, the company decided to offer it as a service to third parties. Now that the platform has matured, those internal applications are starting to migrate over. As such, this makes Windows Azure, in a sense, the opposite to both EC2 and AppEngine. Those products were a way for Amazon and Google to monetize their preexisting infrastructure investment—investment that had to be made simply to run the companies' day-to-day business.

With the newly announced features, there's no doubt that Windows Azure is shaping up to be a cloud computing platform that is both powerful and flexible. Microsoft is taking the market seriously, and its "all in" position seems to represent a genuine commitment to the cloud. What remains to be seen is whether this dedication will be matched by traditionally conservative businesses and developers, especially among small and medium enterprises. A move to the cloud represents a big change in thinking, and the new Windows Azure features will do nothing to assuage widespread fears such as a perceived loss of control. It is this change in mindset, not any technological issue, that represents the biggest barrier to widespread adoption of Windows Azure, and how Microsoft aims to tackle the problem is not yet clear.

IPv6 ( Internet Protocol v6 ) Technology

about ipv6 technologyIPv6 are next generation of IPv4. The addressing scheme used for the TCP/IP protocols is called IP version 4 (IPv4). This scheme uses a 32-bit binary number to identify networks and end stations. This 32-bit scheme yields about 4 billion addresses, but because of the dotted decimal system (which breaks the number into four sections of 8 bits each) and other considerations, only about 250 million usable addresses exist. When the scheme was originally developed in the 1980s, no one ever thought that address would become scarce. The advent of the Internet, however, along with the trend of making many devices Internet-compatible (which means they need an address), such as cell phones and PDAs, makes running out of IPv4 addresses a certainty.


Network Address Translation (NAT) and Port Address Translation (PAT) were developed as solutions to the diminishing availability of IP addresses. NAT and PAT enable a company or user to share a single (or a few) assigned IP addresses among several private addresses that are not bound by an address authority. Although these schemes preserve address space and provide anonymity, the benefits come at the cost of individuality, which goes against the very reason for networking in the first place, which is to allow peer-to-peer collaborations through shared applications.

IP addressing scheme version 6 (IPv6) not only provides an answer to the problem of depleting address space, it allows for the restoration of a true end-to-end model, where hosts can connect to each other unobstructed and with greater flexibility. The key elements in IPv6 are to allow for each host to have a unique global IP address, to maintain connectivity even when in motion, and to natively secure host communications.

IPv6 Addresses The 128-bit address used in IPv6 allows for a greater number of addresses and subnets (enough space for 1015 end points - 340,282,366,920,938,463,463, 374,607,431,768,211,456 total).

IPv6 was designed to give every user multiple global addresses that can be used for a variety of devices, including cell phones, PDAs, IP-enabled vehicles, and consumer electronics. In addition to providing more address space, IPv6 has the following advantages over IPv4:

* Easier address management and delegation
* Easy address autoconfiguration
* Embedded IPSec (encrypted security)
* Optimized routing
* Duplicate Address Detection (DAD)

IPv6 Notation
This figure demonstrates the notation and shortcuts for IPv6 addresses.

128 bits are expressed as 8 fields of 16 bits in Hex notation:
2031 :0000:130F:0000:0000:09C0:876A:130B

An IPv6 address uses the first 64 bits in the address for the network ID and the second 64 bits for the host ID. The network ID is separated into "prefix" chunks. This figure shows the address hierarchy.

IPv6 Autoconfiguration
IPv4 deployments use one of two methods to assign IP addresses to a host: static assignment (which is management intensive) or DHCP/BOOTP, which automatically assigns IP addresses to hosts upon booting onto the network.

IPv6 provides a feature called stateless auto con figuration that is similar to Dynamic Host Configuration Protocol (DHCP). Using stateless configuration, any router interface that has an IPv6 address assigned to it becomes the "provider" of IP addresses on the network to which it’s attached. Safeguards are built into IPv6 that prevent duplicate addresses. This feature is called Duplicate Address Detection (DAD).

IPv6 Security
IPv6 has embedded support for IPSec. The host operating system (OS) can configure an IPSec tunnel between the host and any other host that has IPv6 support.

NAT and PAT
Although Network Address Translation (NAT) causes problems with peer-to-peer collaboration, it is still widely used, particularly in homes and small offices.

* Static NAT uses a one-to-one private-to-public address translation.
* Dynamic NAT matches private addresses to a pool of public addresses on an as-needed basis. The address translation is still one to one.

Port Address Translation (PAT) is a form of dynamic address translation that uses a many private addresses to few or one public address. This is referred to as overloading. It is accomplished by assigning port numbers.

Microsoft Windows 8 Releases

windows 8 releases image
Microsft Windows 8(next generation of Microsoft Windows 7) is starting to take a OS market. Windows 7 is only 10 months old, but it's never too early to glance on down the road at Windows 8. Microsoft’s next version of Windows client is far enough along that the Windows team seems to have begun sharing details about its goals with Microsoft’s PC partners. A leaked slide deck — excerpts of which first appeared on the Web site of blogger Francisco Martin Garcia — don’t reveal a whole lot in terms of specific features. But they do look like the real deal, as Microsoft Kitchen blogger Stephen Chapman — who pulled out even more of the slides in his post — noted.

The leaked slides (dating from April 2010) reference “Windows 8,” not “Windows v.Next” (the Windows client team’s preferred codename these days). They indicate that the next version of Windows, which is expected by many to ship in 2012, will possibly offer some of these features:

- Fast startup (Huzzah!): A new feature combining Logoff and Hibernate to result will give the look and feel of boot/shutdown be faster

- Slates mentioned specifically as a target form factor: It will be interesting to see how Microsoft distinguishes between slates running Windows Embedded Compact and slates running Windows 8

- Push-button reset: A button “that will essentially reinstall Windows while maintaining all of your personal files, applications, settings, etc. without the need for the user to back all of that stuff up,” as Stephen Chapman of Microsoft Kitchen describes it

- Support for facial recognition as one of the ways identity management/log in will be handled

- IE 9 (no surprise there): With another confirmation of August as being the target for the first beta (though I could see this possibly slipping a bit)

- More thorough help and support, enabling users to do more fixing of issues on their own

- A Windows App Store (mentioned in the section on push-button reset)

Microsoft isn’t commenting (so far) on the slides and isn’t even confirming that they are “Genuine” Windows 8 PowerPoints — or how much they reflect current reality. However, I’d note the date on these slides is April 2010 and they sure have the vague look and feel of early Windows documentation.

Google Doodle for 12th birthday of Google

google 12th anniversary imageGOOGLE Inc. is the owner of the Google brand, whose it's main product is search engine "giant" GOOGLE. As one visits the homepage of Google, four colored balls at the top of the Google logo can be seen and as the balls are clicked, it leads to a birthday cake with Google written on it,

Manifesting the 12th birthday of Google

During the early years after its inception, Google celebrated its birthday on the 7th of September. However, for past few years, the date has shifted to 27th September.

Melacak Lokasi Orang dengan Jaringan Selular

google latitude untuk melacak orang hilangAkhir - akhir ini banyak sekali orang hilang yang entah dimana keberadaannya. Ada sebagian yang bisa ditemukan dan ada juga yang tidak kembali hingga saat ini. Namun saat ini telah ada suatu program untuk melacak lokasi atau melacak keberadaan orang melalui internet, yaitu menggunakan google latitude, program yang lahir melalui pengembangan google maps. Dengan software ini, kita bisa dengan cermat melacak keberadaan orang melalui HP/PC. Tentunya dengan bantuan jaringan selular dan Tower/BTS di sekitar kita.

Cara kerjanya yaitu melalui BTS dan jaringan yang paling dekat dengan lokasi kita berada. Kemudian, google latitude akan menghitung koordinat sang pemegang HP. Namun, cara kerja software ini tidak sehebat GPS yang harganya jutaan rupiah. Maksimal jarak yang dapat dikalkulasi oleh google latitude ini adalah 1 km. Itu juga sudah cukup akurat.

Untuk dapat melacak keberadaan orang, anda harus meng-add terlebih dahulu id google/gmail orang tersebut. Dengan begitu anda dan orang tersebut dapat saling berbagi lokasi. Selain itu, dengan software ini anda juga dapat berhubungan secara langsung melalui IM, SMS bahkan via telepon. Sayangnya aplikasi ini masih kompatibel dengan semua ponsel. hanya beberapa ponsel pintar/smartphone saja yang dapat menggunakan google latitude.

Beberapa ponsel canggih yang dapat menggunakan fasilitas google latitude untuk melacak lokasi orang diantaranya adalah Blackberry, Apple IPhone, IPod Touch dan merk lain yang sudah kompatibel dengan OS Windows Mobile 6.5, Symbian S60 dan tentunya Android. Tetapi jangan senang dulu, karena Google Latitude masih belum dapat digunakan di Indonesia. Coba anda buka http://www.google.com/latitude, disana bisa kita lihat tidak ada indonesia dalam daftar negara google latitude. Hanya ada sedikit negara Asia yang dapat menggunakan fasilitas ini, diantaranya india, hongkong dan tetangga ahli jiplak kita yaitu malaysia.

Namun jangan terlalu kecewa, kita masih bisa berharap aplikasi google latitude ini bisa dikembangkan di negara kita, agar bisa membantu kita dalam melacak keberadaan seseorang yang kita sayangi tanpa perlu kuatir akan kejahatan yang selama ini merajalela. Dan juga dapat meminimalisir kejadian orang hilang atau penculikan yang semakin marak.



Sekian, semoga dapat menjadi ilmu yang bermanfaat bagi kita semua.
