21. What is LAN?
Local Area Network (LAN) is a network that uses technology designed to span a small geographical area. For e.g. an Ethernet is a LAN technology suitable for use in a single building.
22. What is WAN?
Wide Area Network (WAN) is a network that uses technology designed to span a large geographical area. For e.g. a satellite network is a WAN because a satellite can relay communication across an entire continent. WANs have higher propagation delay than LANs.
23. What is MAN?
* A Metropolitan Area Network (MAN) is a network that uses technology designed to extend over an entire city.
* For e.g. a company can use a MAN to connect the LANs in all its offices throughout a city.
24. Define Peer to peer processes.
The processes on each machine that communicate at a given layer are called peer to peer processes.
25. What is half duplex mode?
A transmission mode in which each station can both transmit and receive, but not at the same time.
