Q

TYPE OF TOPOLOGY
-Connects each workstation (node) to a single cable.
-All signals are broadcast to all workstations.
-If the signal’s address matches that of the computer, the computer processes the signal. If the address does not match, the computer takes no action and the signal travels down the bus to the next computer.

Q

TYPE OF TOPOLOGY
-All workstations (nodes) are connected to a central unit called a hub.
-This configuration allows cables to have a direct link between entrance facilities, equipment room equipment, telecommunications closet devices, and workstation equipment (e.g., computers, printers, telephone receivers, and so on).

Q

_____________consists of pairs of copper wires that are twisted to certain specifications. Each pair is twisted with a specified number of twists per inch to help eliminate interference from adjacent pairs and other electrical devices; the tighter the twisting, the higher the supported transmission rate but the greater the cost.
