1. Overview

KVM switches are hardware devices that enable users to control multiple computers using a single keyboard, monitor, and mouse. These devices maintain consistent peripheral compatibility while providing secure, low-latency switching between systems. Modern KVM solutions support high-resolution video transmission (up to 4K/8K), USB 3.0+ data rates, and IP-based remote access capabilities. Their importance spans across data centers, industrial control systems, and multi-computer workstations where space efficiency and operational security are critical.
