What is the primary function of a switch in a wired network?
To forward data frames based on MAC addresses to connect devices within a network
To terminate DSL or cable lines for internet connectivity
To assign IP addresses to devices on the network
To connect multiple networks and direct traffic between them
The primary function of a switch in a wired network is to connect devices together on the same network by using MAC addresses to forward data frames to the appropriate destination. Unlike a router, a switch does not facilitate the connection between multiple networks or manage IP address assignments. It is not used for terminating a DSL or cable line, which is the typical function of a modem.
