What does a network switch do?

• A. Connects devices on a network and filters traffic
• B. Routes data between different networks
• C. Resets network connections
• D. Increases internet bandwidth

Answer: (A)

A network switch is a crucial component of a local area network (LAN) that connects various devices, such as computers, printers, and servers, allowing them to communicate with one another. Its primary function is to receive incoming data packets from one device and intelligently filter and forward them only to the target device based on its MAC address. This selective forwarding helps to optimize network traffic and overall performance by reducing the chances of data collisions. The role of a switch is distinct from that of a router, which operates at Layer 3 of the OSI model and is responsible for routing data between different networks. A switch operates at Layer 2, focusing on connecting devices within a specific network. While switches play an essential role in managing local traffic, they do not have the capability to reset network connections or directly increase internet bandwidth. These functions are associated with other networking equipment or configurations. By understanding the specific role of a switch, one can better appreciate its importance in facilitating efficient communication within a network.
