What type of cable is commonly used for connecting computers to a network switch?

Ethernet cable is the standard type of cable used for connecting computers to a network switch. This type of cable is specifically designed for networking purposes, and it utilizes twisted pair wiring to deliver high-speed data transfer. Ethernet cables can support various networking standards such as Fast Ethernet and Gigabit Ethernet, making them suitable for both home and business networks.

Fiber optic cable, while also capable of providing high-speed connections, is primarily used for longer distance transmissions and in environments where electromagnetic interference is a concern. Coaxial cable is most often associated with cable television and broadband internet connections rather than direct computer networking. HDMI cable, on the other hand, is designed for transmitting high-definition video and audio signals between multimedia devices, such as computers and displays, rather than for networking purposes.

Therefore, Ethernet cables are specifically tailored for the task of connecting devices to a network, making them the most appropriate choice among the options provided.
