MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Star topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17.

Detailed explanation-2: -Star Topology: In star topology, all the devices are connected to a single hub through a cable. This hub is the central node and all other nodes are connected to the central node.

Detailed explanation-3: -Star. A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub, switch, or concentrator (See fig. 2).

Detailed explanation-4: -A central hub called Multi-Station Access Unit (MSAU) also known as Media Access Unit. It is used to bind up the entire network together in a single unit in the star type of topology in networking.

Detailed explanation-5: -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.
