PCI Device: Everything You Need To Know About PCI Device

A PCI device is any piece of the compatible computer hardware. It connect directly into a PCI slot on a motherboard of a computer system. PCI stands for Peripheral Component Interconnect, was first introduced to personal computers manufactured by the Intel Corporation company in 1993. Every personal computer manufactured since 1995, nearly having the technology to operate PCI integrated into the motherboard. A PCI connection on a motherboard can be realized a long strip of increased copper connectors encased in plastic. This long strip of connectors is often called a bus.


Essentially, each of the personal computers owns two primary buses, which are connected to the central processing unit (C.P.U). The system bus is the fastest unit, and connects main memory, or RAM, to the CPU. However, the PCI bus is not as fast as the system bus when compared. Its main function is to facilitate communication of hardware devices of all types such as graphics, audio, video, network with the microprocessor.

Network Cards

A network interface card is an example of a PCI device. It’s thickness as the same as a credit card. Having a line of metal connectors on one edge that goes into the motherboard’s PCI bus. The network interface card and USB network adapter work the same way. But it connects inside the computer directly on the motherboard.

There are many PCI network adapters options from which to choose. The two most widespread are the mini PCI and wireless adapter cards. Wireless network cards connected into the motherboard of desktop computers. The mini PCI is the device that is preinstalled in most laptop workstations. It allows you to install a wireless connection to a computer network with your notebook device.

Audio Cards

Audio card or sound card is one of the most widely use among PCI device. It is a hybrid of hardware and software exploit to make a sound. Some sound cards should own their microprocessors, RAM, and as well as the basic input/output. It includes microphone, speaker, and any other connections that are on all sound cards. Software installed along within the hardware lets the PCI sound card to communicate with other programs and the operating system of a computer.

PCI Express

PCI Express is the latest PCI device for graphics, video, and video editing. It’s the most recent type for the PCI bus. It compatible with almost any operating system and consumes more bandwidth than the original PCI technology.


Plug and Play improved to catapult the PCI device into the forefront in computing. The PnP technology is a piece of hardware. It enables the user to inject the PCI card into the computer slot. And everything required to connect the hardware to the computer system transpires automatically. This approach was a collaboration between the Intel Corporation, which understood the PCI.

The PnP technology and the Microsoft Corporation giving the framework needed in the operating system. The PCI device you connect to your computer must be able to work with your system. One needs to remove the computer’s case cover to connect the device into the indicated slot.


USB is another feature for adapters that add functionality to a desktop or Notebook, such as wireless adapters. The USB grants simple plug-in facility, but is less influential than PCI for wireless connectivity, according to a 2011 PC World article. If you have the option of both, here performance is a matter. You may wish to fasten with PCI.
