What is one main function of a network switch?

• A. To divide a network into different segments
• B. To connect devices within the same network
• C. To secure a wireless connection
• D. To provide internet access to multiple users

Answer: (B)

A network switch primarily functions to connect devices within the same network. This device operates at the data link layer (Layer 2) of the OSI model, facilitating communication between various devices, such as computers, printers, and servers, that are part of a local area network (LAN). By using MAC addresses, a network switch forwards data only to the intended recipient device rather than broadcasting it to all connected devices. This targeted approach enhances efficiency and optimizes network performance by reducing unnecessary traffic. It also supports simultaneous data transfers, which improves the overall speed of the network. In the context of the other options, while dividing a network into segments can be a task performed by routers or more advanced managed switches, it's not the primary role of a standard network switch. Securing a wireless connection typically relates to wireless access points and routers that manage security protocols. Providing internet access is mainly the job of a router rather than a switch, as a switch operates within a local network rather than facilitating external connections.
