Which topology is most used in businesses and companies today?
A
Mesh
B
Ring
C
Star
D
Tree
Explanation: 

Detailed explanation-1: -Star topology: Star topology is the most commonly used topology system. Every node connects to a central network device in this layout, like a hub, switch or computer.

Detailed explanation-2: -Advantages. Star topologies are most commonly-used because you can manage the entire network from one location: the central switch. As a consequence, if a node that isn’t the central node goes down then the network will remain up.

Detailed explanation-3: -Star topology is by far the most common. Within this framework, each node is independently connected to a central hub via a physical cable-thus creating a star-like shape. All data must travel through the central node before it reaches its destination.

Detailed explanation-4: -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-5: -Star topologies provide an inherent advantage that a new site can be added with ease; only the central site will have to be updated. 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.
