MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Star topology is a network topology in which each network component is physically connected to a central node such as a router, hub or switch. In a star topology, the central hub acts like a server and the connecting nodes act like clients.

Detailed explanation-2: -In star topology, the central site plays an important role; if it fails, all the connections will go down. Performance of the central hub dictates the performance of the connection.

Detailed explanation-3: -Star topology is a network topology where each individual piece of a network is attached to a central node (often called a hub or switch).

Detailed explanation-4: -Within a star topology, the core switch connects to every other switch creating a star. In order to deliver redundancy within a star topology, two links to each switch are required which are then aggregated using link aggregation.

Detailed explanation-5: -Answers. Explanation: Hub/switch is the central device in star topology.
