The KVM switch is a switch that allows you to use multiple computers with the same keyboard , video display, and mouse.
The full form of KVM Switch is “Keyboard, Video, and Mouse switch.” By the way, most of us do not need to use two computers at a time. Rather I would say that using one computer at a time also sometimes becomes a big challenge.
But there are also situations where using a single keyboard, mouse , and display also becomes a very practical thing with multiple machines.
For example, software programmers use a KVM switch to alternate with two or more computers that use different operating systems. This allows them to develop a crossplatform application across multiple platforms to test their software.
Network administrators often use these KVM switches to monitor and control multiple servers simultaneously. These KVM switches support eight or more computers at the same time.
KVM switch can be turned on by pressing only one button, now administrators can easily see the display of any machine which is connected with the switch and can also control it with a single keyboard and with the help of mouse.
Of course, a home user can also use KVM switches to perform daily tasks. Some people like to have two computers in their desk, such as a home and another work computer, or a Mac and a PC. In such a case, a KVM switch can easily accommodate both machines, allowing them to share the same monitor , keyboard, and mouse.
Because each needs only one, as a result, you will see a very clear formula. With this, you can also put other things on that desk, such as papers, mail, and other things.
Since most keyboards and mice use a USB connection, most KVM switches include USB ports. PS / 2 or serial ports are found in older models.
The connection to the monitor can be either a VGA or DVI port, or even both. If you want to use a KVM switch for your computer setup, then make sure that its ports should match with display and input devices that you are going to use.
