Classification Of Network
Networks usually are classified as a:
- Local Area Network (LAN).
- Metropolitan Area Network (MAN).
- Wide Area Network (WAN).
Local Area Network (LAN)
-A local area network (LAN) is a network that connects computers and devices in a limited geographical area.
-A local area network (LAN) is a network that connects computers and devices in a limited geographical area.
Main characteristics of LAN:
-Areas of coverage: LANs located within the same building (closely positioned group of buildings) such as a home, school computer laboratory, office building.
-Distance: LANs span (cover) distance less than a mile.
-Ownership: LANs are owned and operated by individual organizations.
-Areas of coverage: LANs located within the same building (closely positioned group of buildings) such as a home, school computer laboratory, office building.
-Distance: LANs span (cover) distance less than a mile.
-Ownership: LANs are owned and operated by individual organizations.
Metropolitan Area Network (MAN)
-A metropolitan area network (MAN) is a high-speed network that connects local area networks (LANs) in a metropolitan area.
-A metropolitan area network (MAN) is a high-speed network that connects local area networks (LANs) in a metropolitan area.
Main characteristics of MAN:
-Areas of coverage: MANs connect various locations such as campuses, offices, and government, that are frequently used as links between buildings.
-Distance: MANs span (cover) distance up to 100 miles (161 km).
-Ownership: MANs are owned by a group of users who jointly own and operate the network.
-Areas of coverage: MANs connect various locations such as campuses, offices, and government, that are frequently used as links between buildings.
-Distance: MANs span (cover) distance up to 100 miles (161 km).
-Ownership: MANs are owned by a group of users who jointly own and operate the network.
Wide Area Network (WAN)
-A wide area network (WAN) is a network that covers a large geographical area.
-A wide area network (WAN) is a network that covers a large geographical area.
Main characteristics of WAN:
-Areas of coverage: WANs located within a countryside and worldwide networks, (such as a city, country, or the world) using a communications channel that combines many types of media such as telephone lines, cables and radio waves. The Internet is the world’s largest WAN.
-Distance: WANs span (cover) distance greater than 100 miles.
-Ownership: WANs have no ownership.
-Areas of coverage: WANs located within a countryside and worldwide networks, (such as a city, country, or the world) using a communications channel that combines many types of media such as telephone lines, cables and radio waves. The Internet is the world’s largest WAN.
-Distance: WANs span (cover) distance greater than 100 miles.
-Ownership: WANs have no ownership.
