WI-Fi Technologies 

WiFi, is a mechanism for wireless connecting electronic devices. A device enabled with WI-Fi technology, such as a personal computer, video game console, smartphone, or digital audio player, can connect to the Internet via a wireless network access point. An access point  has a range of about 20 meters (65 ft) indoors and a greater range outdoors. Multiple overlapping access points can cover large areas.

 

Uses of WI-Fi Technologies

To connect to a WI-Fi LAN, a computer has to be equipped with a wireless network interface controller. The combination of computer and interface controller is called a station. All stations share a single radio frequency communication channel. Transmissions on this channel are received by all stations within range. The hardware does not signal the user that the transmission was delivered and is therefore called a mechanism. A carrier wave is used to transmit the data in packets. Each station is constantly tuned in on the radio frequency communication channel to pick up available transmissions.so WI-Fi is the best wireless technology.

Standard devices

USB wireless adapter

A wireless access point (WAP) connects a group of wireless devices to an adjacent wired LAN. An access point resembles a network hub, relaying data between connected wireless devices in addition to a (usually) single connected wired device, most often an ethernet hub or switch, allowing wireless devices to communicate with other wired devices.

Wireless adapters allow devices to connect to a wireless network. These adapters connect to devices using various external or internal interconnects such as PCI, miniPCI, USB, ExpressCard, Cardbus and PC Card. As of 2010, most newer laptop computers come equipped with internal adapters. Internal cards are generally more difficult to install.



Wireless routers integrate a Wireless Access Point, ethernet switch, and internal router firmware application that provides IP routing, NAT, and DNS forwarding through an integrated WAN-interface. A wireless router allows wired and wireless ethernet LAN technology devices to connect to a (usually) single WAN device such as a cable modem or a DSL modem. A wireless router allows all three devices, mainly the access point and router, to be configured through one central utility. This utility is usually an integrated web server that is accessible to wired and wireless LAN clients and often optionally to WAN clients. This utility may also be an application that is run on a desktop computer, as is the case with as Apple's AirPort, which is managed with the AirPort Utility on Mac OS X and Microsoft Windows. Wireless network bridges connect a wired network to a wireless network. A bridge differs from an access point: an access point connects wireless devices to a wired network at the data-link layer. Two wireless bridges may be used to connect two wired networks over a wireless link, useful in situations where a wired connection may be unavailable, such as between two separate homes.
Wireless range-extenders or wireless repeaters can extend the range of an existing wireless network. Strategically placed range-extenders can elongate a signal area or allow for the signal area to reach around barriers such as those pertaining in L-shaped corridors. Wireless devices connected through repeaters will suffer from an increased latency for each hop. Additionally, a wireless device connected to any of the repeaters in the chain will have a throughput limited by the "weakest link" between the two nodes in the chain from which the connection originates to where the connection ends.Distance records (using non-standard devices) include 382 km (237 mi) in June 2007, held by Ermanno Pietrosemoli and EsLaRed of Venezuela, transferring about 3 MB of data between the mountain-tops of El Águila and Platillon.The Swedish Space Agency transferred data 420 km (260 mi), using 6 watt amplifiers to reach an overhead stratospheric balloon.Increasingly in the last few years (particularly as of 2007), embedded Wi-Fi modules have become available that incorporate a real-time operating system and provide a simple means of wirelessly enabling any device which has and communicates via a serial port. This allows the design of simple monitoring devices. An example is a portable ECG device monitoring a patient at home. This Wi-Fi-enabled device can communicate via the Internet. These Wi-Fi modules are designed so that implementers need only minimal Wi-Fi technology knowledge to provide Wi-Fi connectivity for their products.

Intel predicts technology 10GHz chips by 2011 

about technology:

Intel is predicting new technology that its microprocessors will hit 10GHz by the year 2011. In addition, it is currently working on a system bus that is 10 times faster than its upcoming 400 MHz (4*100MHz) Pentium 4 system bus, working at effective speeds of around 4 GHz.

 Intel is working hard to bring high-end applications to your desktop featuring much more video, speech interaction, and more complex and functional user interfaces.
Hopefully, most of you are familiar with Moore's Law, so this doesn't come as a surprise to you. If not, Moore's Law states that the number of transistors in a common microprocessor will double every 18 months. As well, it can be applied to processor speed and many other computing/technology metrics. This law has more or less (no pun intended) held true since the transistor was invented. So, assuming that early 2001 is a time when 1 GHz processors are rampant let's see what we get if we apply Moore's Law:

early 2001: 1 GHz
mid 2002: 2 GHz
early 2004: 4 GHz
mid 2005: 8 GHz
early 2007: 16 GHz
mid 2008: 32 GHz
early 2010: 64 GHz
mid 2011: 128 GHz

This is very interesting indeed. Intel appears to be underestimating progress in 2011 by a full factor of 10. Even by doing that, it's still making headlines with its predictions. Some will call this crazy, but those that yell the loudest have the shortest memories.So it will be the best technology chip.

Best and Powerful Technology Origin Genesis Z68 Desktop Computer

if you're looking for powerful and best performance technology PC, you probably won't be surprised to find it in Origin's latest technology monster desktop. Origin's Genesis Z68 is powerful as well as different-looking in its pretty white chassis.which costs $2464 (as of 9/7/2011), features an Intel Core i5-2500K processor technologies, overclocked to 5.2GHz. It also sports 16GB of RAM, two 60GB solid-state drives in RAID 0, 1TB hard drive, and two Nvidia GeForce GTX 560Ti video cards.

In performance, the Origin Genesis Z68 climbs to the top of the Mainstream Desktop category.
It also performs well in graphics, thanks to the dual Nvidia GeForce GTX 560Ti cards technology. The Performance category still has it beat here, as expected -- those machines generally house larger, more powerful cards (with the commensurate price bump). For example, in our Unreal Tournament 3 graphics tests, the Z68 managed an impressive 203.6 frames per second (highest quality settings, 2560 by 1600 resolution). However, the Origin Genesis 2011 (212.9 fps) beats it, as does the V3 Convoy (224.8 fps).
Four USB ports are along the top of the chassis, as well as headphone and microphone jacks and power and reset buttons. The front of the machine offers a Blu-ray player, a multiformat card reader, two USB 3.0 ports, and another USB port. The back offers six more USB ports, two USB 3.0 technology ports, one each for eSATA, S/PDIF-out, DVI, HDMI, VGA, and gigabit ethernet, and support for 7.1 surround sound. Additional display ports are on the two graphics cards: Each card has two DVI ports and one micro-HDMI port. And if you manage to run out of ports somehow, there’s also Bluetooth.The Z68 is housed in a white BitFenix Shinobi chassis. The sides of the case are white aluminum (with a large, plastic triangular window on the left), while the front and top of the case sport a soft, rubbery texture. This rubbery texture is overly fond of dirt -- after just a few days, our review model looked as if it had been around the block a few times, and we saw a lot of discoloring along the edges of the case. (Keep that in mind if you plan on keeping this huge tower on the floor.) Despite the minor cosmetic issues, the case is both attractive and functional.
If you like to tinker, this is definitely one of the better cases to be working with. Opening up the Z68 is easy, with only a pair of thumbscrews standing in the way. The internal wiring is very neat, though the two graphics cards will limit your space a bit. You'll find one open PCI slot, one open PCIe x16 slot, and one open PCIe x1 slot; however, all but the x1 are blocked by the graphics cards. The four RAM slots are occupied, as are the three 5.25-inch bays inside the chassis, but there are five (of eight) 3.5-inch bays open for hard drives and the like.
As for software and documentation, the Genesis Z68 comes with a lot. Not only do you get about six recovery discs (including EVGA software, Windows 7 Home Premium, and a Blu-ray drive installer disc), but also three booklets and a couple of other peripherals. Origin sends along all of the extra parts (in case you want to get rid of something in the multimedia dock, I assume), as well as two micro-HDMI-to-HDMI converter cables, and an Origin poster and a T-shirt.
There's honestly not a lot wrong with the Origin Genesis Z68 technology, except for the fact that it won’t look stunning for very long, unless your own abode is immaculate. It’s powerful, pretty, and fully-connected. Plus, the price is hard to beat: Older performance machines run from $4000  to $8000 , but have been summarily outpaced by this comparably inexpensive rig. The rankings will almost certainly realign once the old behemoths are updated, but the fastest machines money can buy have reached the realm of mere mortals.

Choose the Best Graphics Card Technology

The graphics card is the heart and soul of your computer. A powerful technology graphics card can mean the difference between a sensory feast and an interactive slideshow. Although upgrading your graphics board is one of the simplest ways to produce noticeable improvements in your PC’s gaming technology performance and other graphical issues, it’s also one of the most confusing: Throwing extra money at the problem isn’t always the best solution, and you have lots of products to choose from. 

 Only two major graphics-processor technologies manufacturers exist these days. In the green corner is Nvidia, which serves up powerful, energy-hungry hardware. In the red corner is AMDhttp://www.amd.com/uk/Pages/AMDHomePage.aspx, whose offerings are competitive but generally less taxing on your electricity bill and your wallet.

Each company does things a bit differently. Consider support for multiple graphics cards: AMD calls its technology CrossFire and Nvidia calls its version SLI, but both allow you to pair up identical graphics cards to eke a bit more performance out of your PC. You won’t enjoy a 100 percent performance gain by slapping another card into your rig, but you will see a worthwhile speedup if you can afford the cost--and if your motherboard (and power supply) can support more than one card.Graphics cards have quite a bit more to offer than just making your games pretty. If you want multiple displays, look to AMD, which offers Eyefinity t: A single AMD card can support up to three monitors, which can be a boon if you have plenty of desk space and you like to give games as much real estate as you can muster. Nvidia’s graphics cards are limited to two screens only; if you want more, generally you’ll need to run two cards in SLI.Another important consideration, for some gamers, is 3D. Both AMD and Nvidia make graphics cards that are capable of 3D video playback and 3D gaming technology, but Nvidia’s 3D Vision ecosystem has been around for years, and you’ll find various games and hardware built with Nvidia’s technology in mind.
