What function does a router perform in a network?

• A. Allows multiple computers to access the internet simultaneously
• B. Connects devices for local data sharing
• C. Stores data for retrieval
• D. Encrypts traffic on a network

Answer: (A)

A router primarily functions to allow multiple devices to communicate with one another and to access the internet. It does this by directing data packets between the devices within a local network as well as between that network and the wider internet. When multiple computers or devices are connected to a single internet connection, the router manages the data traffic, ensuring that each device receives the information it needs while maintaining an efficient flow of data. This capability enables seamless internet access for several devices at the same time, which is essential in both home networks and larger enterprise setups. While other devices like switches and hubs facilitate local data sharing and services like servers may store data or manage encryption, the central role of a router is its ability to connect multiple devices to the internet and facilitate their communication.
