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

1. To connect different types of networks

2. To route data between devices within the same network

3. To provide wireless connectivity

4. To extend the range of a network

The correct answer is: To route data between devices within the same network

The function of a switch in a network is primarily to route data between devices within the same network. A switch operates at the data link layer (Layer 2) of the OSI model and is designed to receive incoming data packets and redirect them to their intended destination on the local network. It does this by using MAC addresses to identify devices connected to it, ensuring that data is sent only to the relevant device rather than broadcasting to all devices, which improves efficiency and reduces network congestion. Unlike devices that connect different types of networks, such as routers, a switch is specifically focused on managing data traffic among devices on the same local area network (LAN). Providing wireless connectivity typically involves access points or routers rather than switches, as those devices manage wireless signal transmission. Similarly, while switches can be used in conjunction with other devices to extend the range of a network, that function isn't the core purpose of a switch itself; rather, it is to manage data flow within a single network.
