Management Information System (MIS) Practice Exam

What device is used to connect two or more individual networks?

1. Router

2. Port

3. Console

4. Codec

The correct answer is: Router

The device that connects two or more individual networks is a router. Routers are essential for directing data traffic between different networks, ensuring that data packets are sent to the appropriate destination. They operate at the network layer of the OSI model, analyzing incoming data packets and determining the best path for those packets to travel. In contrast, a port refers to a physical interface on a device that allows for connectivity but does not itself connect networks. A console is typically an interface for local management of devices, allowing administrators to interact with a router or switch directly but is not used for connecting networks. A codec is primarily used for encoding and decoding digital signals for audio and video communication, not for connecting network systems. Thus, the router’s specific capability to connect diverse networks makes it the correct choice in this context.
