Computer Network Classification
- A Computer Network Classification is a system in which multiple computers connected to each other to share information and resources.
- The physical connection between networked computing devices established using either cable media or wireless media.
- The best-known computer network is the Internet.
Local area network (LAN)
- It privately-owned networks within a single building or campus of up to a few kilometers in size.
- They widely used to connect personal computers and workstations in company offices and factories to share resources (e.g., printers) and exchange information.
- LANs are easy to design and troubleshoot
- In LAN, all the machines 000000connected to a single cable.
- Different types of topologies such as Bus, Ring, Star, and Tree are used.
- Moreover, The data transfer rates for LAN is up to 10 Gbits/s.
- They transfer data at high speeds. The high transmission rate is possible in LAN because of the short distance between various computer networks.
- They exist in a limited geographical area.
Wide Area Network (WAN)
- WAN spans a large geographical area, often a country or region.
- WAN links different metropolitan’s countries and national boundaries thereby enabling easy communication.
- Also, It may locate entirely within a state or a country or it may interconnect around the world.
- It contains a collection of machines intended for running user (i.e., application) programs. We will follow traditional usage and call these machines hosts.
- Moreover, The communication between different users of WAN established using leased telephone lines or satellite links and similar channels.
Metropolitan area network (MAN)
- MAN is a larger version of LAN which covers an area that is larger than the covered by LAN but smaller than the area covered by WAN.
- A metropolitan area network or MAN covers a city.
- The best-known example of a MAN is the cable television network available in many cities.
- MAN connects two or more LANs.
- WLAN technology allows computer network devices to have network connectivity without the use of wires, using radio waves.
- Also, These networks use an infrared link, Bluetooth or low power radio network operating at a bandwidth of 1-2 Mbps over a distance of 10m.
- Moreover, At the top level, wireless networks can be classified as wireless LAN, wireless MAN, and wireless WAN.
- The wireless LANs are further classified as Personal Area networks (e.g. Bluetooth, wireless sensor networks) and Business LAN (e.g. 802.11b).
