Which device is used to connect a computer to a network?

• A. Router
• B. Modem
• C. Switch
• D. All of the above

Answer: (D)

The choice of all devices being correct is valid as each one plays a role in connecting a computer to a network, although their specific functions may differ. A router connects multiple networks together, often routing data between a local area network (LAN) and the internet. It manages traffic and directs data packets effectively, making it a crucial component in network communication. A modem, short for modulator-demodulator, serves as the gateway between your home network and the internet. It converts digital data from a computer into an analog signal that can be transmitted over telephone lines, cable systems, or satellite links, and vice versa. This is essential for internet access. A switch operates within a LAN to connect multiple devices, such as computers and printers, allowing them to communicate with each other efficiently. It functions at a data link layer and facilitates the transfer of data between devices on the same network. Together, these devices can establish a complete networking environment, making the statement that all of them can connect a computer to a network accurate. Understanding the roles of each device is essential for effective network configuration and management.
