Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which network topology uses a backbone to connect all of the computers?
A
Bus
B
Ring
C
Star
D
None of the above
Explanation: 

Detailed explanation-1: -Bus topology, also known as line topology, is a type of network topology in which all devices in the network are connected by one central RJ-45 network cable or coaxial cable. The single cable, where all data is transmitted between devices, is referred to as the bus, backbone, or trunk.

Detailed explanation-2: -Bus topology uses one main cable to which all nodes are directly connected. The main cable acts as a backbone for the network. One of the computers in the network typically acts as the computer server. The first advantage of bus topology is that it is easy to connect a computer or peripheral device.

Detailed explanation-3: -In a bus topology, all nodes in the network are connected directly to a central cable that runs up and down the network-this cable is known as the backbone . Data is sent up and down the backbone until it reaches the correct node.

Detailed explanation-4: -Mesh Topology Mesh topology is the kind of topology in which all the nodes are connected with all the other nodes via a network channel. Mesh topology is a point-to-point connection. It has n(n-1)/2 network channels to connect n nodes.

Detailed explanation-5: -Bus Topology The main cable serves as the network’s spine. All nodes in a Bus Topology are linked to the Taps and Drop Lines via the bus. Drop Lines are the connections between the central wire or bus and the nodes in this case.
