Why each option
A KVM (Keyboard, Video, Mouse) switch allows multiple computers to share a single set of peripherals, and is typically connected using DVI cables for video and USB cables for keyboard and mouse.
A touch screen connects to a host via a single video cable (HDMI or DisplayPort) and a single USB cable for touch input - it does not use multiple DVI and USB connections to multiple computers.
An LCD panel is a monitor that connects to a single video source - it does not use multiple DVI and USB cables connecting to multiple computers.
A webcam connects to a single computer via a single USB cable - it does not use DVI cables or multiple USB connections.
A KVM switch sits between multiple computers and one set of peripherals (keyboard, video monitor, mouse). DVI cables carry the video signal from each connected computer, and USB cables carry keyboard and mouse input, enabling the user to switch control between machines without physically reconnecting devices.
