#KVM switch, how does it work?
Simply put, a KVM switch allows you to switch between different computer sources (or computer cases) while still using the same keyboard, monitor, and mouse; in fact, this That's what KVM means: keyboard, video, mouse. This means that if you need to use multiple PCs, you don't have to buy a separate monitor, keyboard, and mouse for each PC. Instead, you just buy one and use a switch to switch from PC to PC.
That being said, the term KVM is a bit misleading, and while the original KVM switches only handled these three, modern switches often handle much more, including audio and USB ports, among others. There are even KVM switches that only switch between one input, such as the Gana 3-Port HDMI Switch, although these switches are often referred to only by the data they handle, such as audio switchers or keyboard switchers.
So how exactly do they work? Well, in the old days, plug-and-play technology didn't exist, so every time you wanted to change your keyboard or mouse, you had to reboot your computer so that the CPU could detect any peripherals. While this is no longer the case, KVM switches still do something similar in that they trick the CPU into thinking there is a connection so that when you finally switch, it goes smoothly.
How it does it is a bit complicated, but basically, it emulates the computer's peripherals and constantly maintains a "fake" signal. When you switch, the KVM switch replaces the analog signal with your actual peripheral signal, providing a smooth and unnoticeable transition.
