COMPUTER FUNDAMENTALS

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.

Detailed explanation-2: -Hubs connect multiple computer networking devices together. A hub also acts as a repeater in that it amplifies signals that deteriorate after traveling long distances over connecting cables. A hub is the simplest in the family of network connecting devices because it connects LAN components with identical protocols.

Detailed explanation-3: -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.
