5. Computer networks Common types of computer networks
1.Local Area Network (LAN): It is an Interconnection of small devices covering a short distance or small geographical and physical area. Its use in a personal computers in home offices, or schools.
Types of LAN : The wired LAN , The wireless LAN.
2.Wide Area Network (WAN ) : It is a collection of local area networks and other network types though a router. It covers a large geographical distance.
Types of WAN : Private Network., Integrated Services Digital Network, Value Added Service, PSDN, PSTN.
3.Metropolitan Area Network (MAN): Interconnects a number of (LANs) using a high capacity backbone technology. Its a large computer network that usually spans a city or a large campus. its geographic scope falls between a WAN and LAN.
Types of MAN: Asynchronous Transfer Mode (ATM), Fiber Distribution Data Interface (FDDI) ,Switched multi megabit data service (SMDS).

6. Computer networks Differences between LAN, WAN, & MAN
The differences between LANs, WANs, and MANs are indeed greater than just in term of size. There are differences in network topology, hardware requirements, software requirements as well as technical specifications and cost.

7. Computer networks Conclusion
The networks of LAN, WAN, and MAN provides lots of benefits that help users to communication with the world around them. The network has become a vital part of our life to accomplish tasks.
