A switch with 5 Ethernet ports makes it possible to connect up to 5 extra devices to your network. The size and number of connections of 5 port switches makes them especially suitable for home use. This is useful if, for example, you have few available ports on your router. Switches with 5 ports sometimes have extra options. For example, with a managed switch you have more options as an administrator and with a 5-port PoE switch it's possible to supply devices with power.
