Which topology requires a central controller or hub.
Star topology requires a central controller or hub.
Star topology and tree topology requires central controller or hub. Mesh, ring, bus topologies doesn't need hubs.
In star topology, every node (computer workstation or any other peripheral) is connected to a central node called hub, router or switch. The switch is the server and the peripherals are the clients.
A Star network is one of the most common computer network topologies. In its simplest form, a star network consists of one central hub which acts as a conduit to transmit messages. In star topology, every host is connected to a central hub.
A star topology is the most common type of topology used in homes and offices. This type of topology is where all of the computers and devices on the network connect to a central device, thus forming a star. The central device that provides a common connection point for nodes on the network is called a hub.
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). The attachment of these network pieces to the central component is visually represented in a form similar to a star. Star topology is also known as a star network.
