There are several types of KVM switches available, including analog KVM switches, digital KVM switches, and IP KVM switches. USB keyboards, mice, and I/O devices are the most common devices connected to a KVM switch. The classes of KVM switches discussed below are based on different types of core technologies, which vary in how the KVM switch handles USB I/O devices—including keyboards, mice, touchscreen displays, etc. What is a KVM. A single-monitor office KVM, a dual-monitor gaming KVM, a rackmount-style 16-port KVM, and a KVM compatible with Thunderbolt™ 4 laptops are built for different problems. This guide explains the major types of KVM switches, how they differ in real-world use, and how TESmart product categories fit. Desktop KVM switches are compact devices that allow a user to access two, four, eight, or 16 computers from a single user console eliminating the need for extra peripherals, while providing faster access to critical applications. They reduce the number of peripherals that data centers and server farms require, enabling businesses to conserve space, cut power. A KVM switch includes a video switch that syncs pulses between monitors and computers and a data switch that sends and receives data from input devices like keyboards and mice.
