There are four main types of networks: local area networks (LANs) which connect devices within a small area like a home or office; personal area networks (PANs) which connect devices within a user's immediate vicinity; metropolitan area networks (MANs) which connect devices within a large city or area; and wide area networks (WANs) which connect groups of computers over large distances, often used by large businesses to connect office networks across locations. Networks provide advantages like reduced costs, shared applications and resources, and easier collaboration, but also disadvantages such as security threats, loss of privacy, and potential loss of productivity.

1. Types of Network

2. They are Four of Networks:
1.LAN (local area network)
2.PAN (personal area network)
3.MAN (metropolitan area network)
4.WAN (wide area network)

3. LAN (local area network)
A local area network is a computer network that interconnects
computers within a limited area such as a residence, school,
laboratory, university campus or office building.

4. PAN (personal area network)
A personal area network (PAN) connects electronic devices within a
user's immediate area. The size of a PAN ranges from a few
centimeters to a few meters. One of the most common real-world
examples of a PAN is the connection between a Bluetooth earpiece
and a smartphone. PANs can also connect laptops, tablets, printers,
keyboards, and other computerized devices.

5. MAN (metropolitan area network)
A metropolitan area network (MAN) is a computer
network that connects computers within a metropolitan
area, which could be a single large city, multiple cities
and towns, or any given large area with multiple
buildings.

6. WAN (wide area network)
A wide area network (WAN) is a large
computer Network that connects groups of computers
over large distances. WANs are often used by large
businesses to connect their office networks; each
office typically has its own local area network,
or LAN, and these LANs connect via a WAN.

7. Advantages and Disadvantages of Networking:
Advantages:
• Reduce hardware costs.
• Sharing application.
• Sharing information resources.
• Centralized data management.
• Connecting people.
Disadvantages:
• Loss of autonomy.
• Lack of privacy.
• Security Threats.
• Loss of productivity.
