A KVM (keyboard, video, mouse) switch allows you to control multiple computers from a single keyboard, monitor, and mouse. It’s a hardware device that acts as a bridge between your peripherals and computers, letting you switch seamlessly between them.
What is a KVM Switch?
A KVM switch has ports to connect your keyboard, monitor, and mouse on one side, and ports to connect your computers on the other side. Using a button, menus, or hotkeys, you can switch which computer’s video output is sent to the monitor, and which computer receives inputs from the keyboard and mouse.
This allows you to access multiple PCs from the same desk space. KVM switches reduce clutter and make it convenient to alternate between devices as needed without swapping cables back and forth.
What is a Software KVM and Is It Good?
A software KVM performs similar functions as a hardware KVM switch using just software rather than external hardware. This allows controlling multiple computers from one keyboard and mouse without a separate device.
