Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which best defines a star network?
A
Each device is connected by an individual cable directly to the server. These are usually the layout of choice in schools and offices because they tend to be the most reliable of the topologies.
B
Where some or all of the workstations or other devices are connected directly to each of other. Most are usually connected to the node that they exchange the most data with.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -A star network is a local area network (LAN) topology in which all nodes–personal computers (PCs), workstations or other devices–are directly connected to a common central computer that is often referred to as a hub. Therefore, a star network is often referred to as a hub-and-spoke network topology.

Detailed explanation-2: -Bus topology is a network type where every device is connected to a single cable that runs from one end of the network to the other. This type of network topology is often referred to as line topology. In a bus topology, data is transmitted in one direction only.

Detailed explanation-3: -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.
