Types of Computer Networks

There are many different types of computer networks, each with its own unique purpose and characteristics. Some of the most common types of networks include:

• Local Area Networks (LANs): LANs are small networks that connect computers within a limited area, such as a home or office.
• Wide Area Networks (WANs): WANs are large networks that connect computers over a wide geographic area, such as a country or continent.
• Metropolitan Area Networks (MANs): MANs are networks that connect computers within a metropolitan area, such as a city.
• Virtual Private Networks (VPNs): VPNs are networks that allow users to securely access a private network over the internet.

How Computer Networks Work

Computer networks work by using a variety of technologies to connect computers and devices. These technologies include:

• Network cables: Network cables are used to physically connect computers and devices to a network.
• Network switches: Network switches are used to connect multiple computers and devices to a network and to forward data between them.
• Network routers: Network routers are used to connect different networks to each other and to forward data between them.
• Network protocols: Network protocols are sets of rules that govern how data is transmitted across a network.
