Type of Network:

Commonly it was divided into 6 parts. Let’s start to know each one by one:

1: Local Area Network (LAN) 

LAN connects a group of computers, printers, and other equipment to share information and resources at a short distance within a building or a group of about two or three buildings. Colleges, hospitals, and businesses usually manage and maintain LAN. Using the router, LAN may connect to the extensive area network.

2: Wide Area Network (WAN) 

WAN allows computers and other devices to be remotely connected over one large network to communicate even when they’re miles away. It connects all computers together around the world. The Internet is the basic example of a WAN. A WAN is often owned and maintained by several administrators or the general public due to its extensive reach.

3: Metropolitan Area Networks (MAN) 

These types of networks are larger than LANs but smaller than WANs. MAN covers a large geographic region, usually a town or metropolis, but occasionally a campus. Ownership and maintenance are handled by a single person or company.

4: Personal Area Network (PAN) 

PAN is centered on a single individual in a building and includes a wireless modem, one or more computers, phones, printers, tablets, etc. These networks are generally found in small workplaces or homes and are operated from a single device by one person or organization.

5: Campus Area Network (CAN) 

These networks, which are bigger than LANs but smaller than MANs, are often found in colleges, big schools, or small companies. Users can share resources if distributed across several buildings relatively close to one another.

6: Virtual Private Network (VPN) 

A VPN allows users to send and receive data as though their devices are connected to the private network, even when they are not, by extending a private network across the Internet. A virtual point-to-point connection enables users to access a private network remotely.
