Features of Peripheral Component Interconnect Express
Written by Bella martin
Most of the people who are using Window 7, Window Vista, and Window XP and complaining for sluggish computer speed are not aware of the importance of PCI (Peripheral Component Interconnect).For people from non technical background these things look like rocket science. But you must be aware of these things if you want to enhance your computer performance.PCI is responsible for establishing communication betwee
Microprocessor and there peripheral device like sound card, graphics card. For years now, the Peripheral Component Interconnect (PCI) has controlled the show from the inside of your computer by connecting network, video and sound cards to the motherboard. It's gotten better with the PCI Express (PCIe), which promises improved functionality, and delivers it too. PCI stands for "Peripheral Component Interconnect." It is a hardware bus designed by Intel and used in both PCs and Macs. Most add-on cards such as SCSI, Firewire, and USB controllers use a PCI connection. Some graphics cards use PCI, but most new graphics cards connect to the AGP slot. PCI slots are found in the back of your computer and are about 3.5" long and about 0.5" high.
PCIe provides the following features:
• PCIe is a far cry from the earlier versions of serial connections, which moved data packets at a crawling pace. The PCIe, despite being a serial connection, has several lines which separately lead to each respective device. In other words, each peripheral device gets its own connection, translating into improved computer performance.
• Other than its point-to-point connection system, the PCIe permits hot plugging and thankfully consumes less power. You can use it as an input-output channel for desktops, laptops, cell phones and servers as well. If you're wondering if it would be compatible with your current OS and PCI drivers, then relax; as the PCIe allows that. It is remarkable for regular users to say the least, who stand back and watch every miniscule upgrade that renders their computer obsolete.
• Now for PCIe's best feature. Yes, it's not the compatibility, but the scalability, which means that the bandwidth can be added by simply increasing the number of lanes. In all probability, this feature will ensure its use in the years to follow.
The flavors of the PCIe represent the number of lanes - x1, x2, x4, x8, x16 and x32, and all of them offer more bandwidth compared to PCI. It is the x16 flavor that you need to use for your graphics card, effectively replacing the AGP, while the x1 and x2 flavors are used to connect your computer to peripheral devices.
With increase of number of lanes the bandwidth attached also increases.The latest PCIe flavour x32 offers as bandwidth of 16000 MB/sec and the bandwidth limit alleviates as we move down to PCIe with lower number of lanes x16 offers 8000 MB/sec.
PCIe compatibiltiy is one of the most important issue of concern.Currently we all are using PCIe 3.0 and the latest PCIe still to be launched in the market.If you are planing to buy a new computer or upgrading your old computer then you should wait for the PCIe next version. It is expected to be launched very soon and computer geeks are speculating to provide better services with enhanced speed.If you have any computer problem then you can use the third party computer repair services of some of well reknown companies like IMPCSUPPORT. They also provide 24*7 online technical supports for 365 days.
