There are four main types of computer networks: 1) PAN (Personal Area Network) connects devices within 10 meters and includes mobile devices, tablets, desktops and laptops. 2) LAN (Local Area Network) connects computers within a small area like a school or office over distances between 1-10 km and can connect up to 5000 devices to a central server. 3) MAN (Metropolitan Area Network) spans a city or campus using protocols like RS-232 and fiber optics and provides faster communication over LANs. 4) WAN (Wide Area Network) is a large network that can span an enterprise or organization and is used for business, government, or education purposes with shared

- 2. CLASSIFICATION OF COMPUTER NETWORKS In classification of computer networks, there are four types of computer networks. Let's discuss it. This four type are : PAN: PAN stands for Personal Area Network. Thomas Zimmerman was a first time research scientist who brought the idea of the Personal Area Network. Upto 10 meters can be covered by PAN. PAN can include various devices like mobile devices, tablet, desktop, and laptop. 2
- 3. LAN: LAN stands for Local Area Network. It’s a group of computers connected to each other in a small area such as school, college, university, home, office or a laboratory. LAN can cover 1 Kilometer distance to 10 Kilometer distance. In LAN 5000 devices can be interconnected. All device data is stored in a single hard disk, it’s called the server computer. LAN provides high security to their users. 3
- 4. MAN: MAN stands for Metropolitan Area Network. It can cover a entire city, college campus or a small religion. Most widely used protocols in MAN are RS-232. Frame Relay, ATM, ISDN, OC-3, ADSL etc. MAN use for faster communication like fiber optic cables. 4
- 5. WAN: WAN stands for Wide Area Network. The WAN network system is used as a large network system. It can be used for an enterprise or an organization. WAN can be used in the field of business, government or education purposes. Also, in WAN resources are shared all over the user, so all users can access the files. 5
