How Does KVM Switch Work?

KVM Switch

It comes in a wide variety of shapes and sizes, from small home switches designed to switch between only two computers to complex enterprise-grade switches with an almost insane number of ports. But all switches work essentially the same, despite their differences.

The keyboard, video, and mouse of one computer are connected to several computers via a switch. By changing the input on the switch, the user can choose which computer they want to control. The keyboard, video, and mouse inputs are transferred to the computer that is selected via the switch, giving the user control over it. The inputs are then forwarded to another computer when the switch is set to that one, enabling the user to operate it instead.

Additionally, some switches include features like remote access, audio support, and USB support. Some switches also come equipped with built-in video processors that can enhance the connected systems’ video quality. Virtual KVM is the name for software-based KVM systems that use software to simulate the capabilities of a switch on a host computer. Therefore, let’s look at KVM Switch price ranges.

KVM Switch Price

The number of ports and features a switch has will determine how much it costs. Prices for basic switches with 2-4 ports range from $20 to $50. Switches in the midrange, with 8–16 ports, can cost you $100–300. Switches with extensive features and more than 16 ports can cost $500 or more. Before making a purchase, it’s important to consider your unique requirements and the number of devices you’ll be connecting to the switch.

Frequently Asked Questions (FAQs)

Q1. What is the key purpose of a KVM Switch?

Ans. It is a device that allows a user to control multiple computers using a single keyboard, mouse, and monitor. The key purpose of this device is to save space and reduce the need for multiple monitors, keyboards, and mice for controlling multiple computers. It also allows for easy switching between computers without having to physically move the peripherals.
