Which of the following hardware devices links a number of computers together to form an Ethernet LAN?

A server provides shared resources or services to clients but does not function as the network device that physically links computers together into a LAN.

A switch operates at Layer 2 of the OSI model and uses MAC address tables to forward Ethernet frames between connected hosts, creating a local area network. Unlike older hubs, switches provide dedicated bandwidth per port and reduce collision domains. This makes the switch the correct hardware device for linking computers into an Ethernet LAN.

A connector is a passive physical component (such as an RJ-45 plug) used to terminate cables and does not perform any network switching or linking function.

An access point creates a wireless (Wi-Fi) network segment, not a wired Ethernet LAN connection between computers.

A terminal is an endpoint device used for input/output interaction with a system and has no role in linking computers together into a network.
