What is the basic function of a switch in a network?

  • Assigning IP addresses dynamically
  • Creating virtual private networks
  • Filtering packets based on IP addresses
  • Forwarding data to specific devices based on MAC addresses
A switch's basic function in a network is to forward data packets to specific devices based on their MAC addresses. Unlike hubs, which broadcast data to all connected devices, switches maintain a MAC address table to determine where to send incoming packets. This improves network efficiency by reducing unnecessary traffic and collisions. Switches operate at Layer 2 (Data Link Layer) of the OSI model.
