Question

In a _____ a number of small computers or peripheral devices are linked to a central unit

Answer 1

Answer:

In a star network(topology) a number of small computers or peripheral devices are linked to a central unit.

Explanation:

• The arrangement of a network which contains nodes and connecting different lines via sender and receiver, is referred  as network topology.
• The various network topologies are: Mesh Topology ,Star Topology, Bus Topology, Ring Topology, Tree Topology , Hybrid Topology .

• A star network is a local area network (LAN) topology in which all nodes whether its a personal computers (PCs), workstations or other devices, are directly connected to a common central unit which is  referred as a hub.
• The star network is also referred to as a hub-and-spoke network topology.

• Every workstation  is indirectly connected to other workstations using the hub as an intermediary device.

Answer 2

Answer:

In Star topology a number of small computers or peripheral devices are linked to a central unit

Explanation:

• Each node, such as offices, printers, laptops, servers, and so on, is connected directly to a central computer known as a network switch in a star architecture. A wire connects each office's network interface card (NIC) to a network switch. It is one of the most widely used networking systems. It consists of several devices or computers that are linked to a centralised computer. This central mainframe is known as a server, and the machines that connect to it are known as clients or workstations.
• The message is routed to the centralised computer to control communications or data transmission activities during communication or data transfer.
• It is extremely dependable; if one cable or gadget breaks, the others will continue to function.
• It is efficient since no data collisions may occur.
• Less costly since each device only requires one I/O port and desires to be linked to a hub through a single link.
• Robust in nature is easier to include
• Because the relationship is frequently immediately detected, defect identification is simple.
• There are no network disturbances when attaching or disconnecting devices.
• Each device just requires one port to connect to the hub.
• If N devices are linked in a star, the number of cables necessary to connect them is N. As a result, lining up is simple.
• More cable is required than for a linear bus.
• If the connected network device (network switch) fails, the nodes associated are deactivated and unable to communicate with the network.
• Because of the cost of the connecting devices, this design is more expensive than linear bus topology (network switches)
• If the hub fails, everything fails; none of the devices can function without the hub.
• Because it is the centre mechanism of the star, the hub needs greater resources and frequent maintenance.
• Extra hardware (hubs or switches) are required, which raises the cost.
• The performance is based on a single concentrator, i.e. the hub.
