How do computers typically locate or identify other devices on a network?

• A. Routing
• B. Addressing
• C. Broadcasting
• D. Packet switching

Answer: (B)

Addresses are what let devices be identified on a network. Each device gets a unique address, like an IP address for the network level and a MAC address for the local link, and names can be resolved to those addresses with systems like DNS. When one computer wants to reach another, it uses the destination’s address so the data can be directed to the correct device. Behind the scenes, protocols map between different address types (for example, ARP translates an IP address to a MAC address on the local network), and routers use IP addresses to decide where to forward packets. Routing is about choosing the path for data, not naming the destination. Broadcasting sends a message to all devices on a local network, which isn’t typically how a specific device is located. Packet switching describes how data is broken into packets and sent, not how devices are identified.
