Define the Types of Computer Network
Computer networks fall into three classes regarding the size, distance and the structure namely: LAN (Local Area Network), MAN (Metropolitan Area Network), WAN (Wide Area Network). A LAN links a small group of functionally same workstations within a local geographic area like a series of adjacent cubicles or offices on the similar floor. Once the network expands to contain other floors or divers office within a metropolitan area, it becomes a MAN. Finally, a WAN is simply a LAN of LANs. WANs expand the boundaries of networking to a global or even galactic scale.
Half duplex is analogous to a one a lane bridge, it can handle traffic in both directions but no at the similar time.
At the Physical layer of the OSI model Repeaters work by regenerating the signal to extend the distance it can travel.
