A pcie interface is a great tool, whether you know what it is, or not. Even the fastest computer isn’t much use without a way to interact with it or extract information from it, which is what it means to interface. The way you do that is through peripherals, also known as the monitor, keyboard, mouse, extra drives, printers, speakers, microphones, cameras, and any other kind of equipment you might plug into the computer to work it.
In the past, when these devices were attached to the computer, there was one main address, or point of connection, into which everything was plugged. This meant that everything had to compete for bandwidth, which affected the speed of the computer to work. If one needed to function, it affected the speed and effectiveness of all of them. This is called latency. That is the speed it takes the computer to be given a request, process that request, and provide the answer. The longer the latency, the slower the computer.
A pcie interface gives each device its own lane to connect to the computer. This means that they no longer have to fight for power. Each device is independently supplied. It increases the computers performance and increases the data transfer rates. It can also save space, which is helpful in today’s world of faster computers in smaller packages.
One of the major benefits of a pcie interface is the ability of the user to easily update and change devices. Hot swapping and hot plugging are both terms used to describe changing or adding devices while the computer is still on. With previous technologies, trying to update without turning off the computer would result in a malfunction or error. Now, things can be easily added or exchanged without interrupting computer usage.
