Which of the following would be used to expand the number of wired devices on a network?

A network switch is specifically designed to connect multiple wired devices on a local area network (LAN), allowing them to communicate with each other and often with other networks. It expands the number of available Ethernet ports for wired clients.

An access point (AP) extends a wireless network, converting wired signals to wireless and vice-versa, but does not primarily expand wired ports.

A router connects different networks and routes traffic between them, primarily handling network addressing and security, not just expanding wired ports within a single LAN.

A modem converts signals between a digital device and an analog line (like cable or DSL), providing internet access but not expanding internal wired network ports.
