MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -a) Star topology is a type of connection where all the computers are connected to a central point that is the hub/switch, but not connected with each other directly. This type of connection is used to connected devices to the host/server in a Local Area Network (LAN).

Detailed explanation-2: -A hub is a common connection point for devices in a network, commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Detailed explanation-3: -Star Topology: Many home networks use the star topology. A star network features a central connection point called a “hub” that may be a hub, switch or router.

Detailed explanation-4: -The star topology has a central connection point, which is normally a device such as a hub, switch, or router. Each host on a network has a cable segment that attaches the host directly to the central connection point. The advantage of a star topology is that it is easy to troubleshoot.

Detailed explanation-5: -Expert-Verified Answer. 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.
