BUS is a networking topology that connects networking components via a single cable or a series of linearly connected cable segments.

• A bus topology example is connecting two floors with a single line.
• A bus topology is also used in Ethernet networks.
• In a bus topology, one computer acts as a server and the other computers act as clients. The server's purpose is to exchange data between client computers.
• Using a bus topology network, printers, scanners, and other input/output devices can be added to the office/home.
