What is a bus topology? What are the advantages and disadvantages?

(1) Easy wiring and low cable consumption.

(2) High reliability.

(3) Easy to expand.

(4) Convenient installation.

Disadvantages of bus topology:

(1) Fault diagnosis is difficult.

(2) Fault isolation is difficult.

(3) repeater configuration.

(4) The failure of communication medium or an interface point in the middle will lead to the paralysis of the whole network.

(5) The terminal must be intelligent.

bus topology

Extended data:

Bus topology refers to a single data transmission line as the communication medium, and all stations are directly connected to the communication medium through corresponding hardware interfaces, and can be received by all other stations. The user nodes in the bus network topology are servers or workstations, and the communication medium is coaxial cable. Since all nodes share a common transmission link, only one device can transmit at a time.
