Understanding Network Types and Functions

The video tutorial introduces three types of computer networks: Local Area Network (LAN), Metropolitan Area Network (MAN), and Wide Area Network (WAN). It explains the purpose, characteristics, and drawbacks of each network type. LANs are used for resource sharing within a limited range, MANs connect multiple LANs within a city, and WANs cover larger geographical areas using satellites or telephone cables. The tutorial also highlights the differences in range, security, and maintenance among these networks.
