Which device is typically used to connect a computer to the internet?

• A. Router
• B. Repeater
• C. Access Point
• D. Switch

Answer: (A)

A router is typically used to connect a computer to the internet because it routes data packets between the local network (such as a home or office) and the internet. The router assigns IP addresses to the devices on the local network, enabling them to communicate with each other and with external networks. It also manages traffic, ensuring data is sent to the correct destination and can provide security features like a firewall. In contrast, a repeater is used to extend the range of a network by amplifying signals, but it does not provide connectivity to the internet directly. An access point allows wireless devices to connect to a wired network, functioning as a bridge, but it relies on another device, typically a router, for internet access. A switch connects devices within a local network, facilitating communication between them, but it does not connect to the internet itself. Thus, the router plays the central role in achieving internet connectivity for the entire network.
