A network is a group of two or more computer system linked together.
In computer networks, networked computing devices exchange data with each other using a data link.
There are many types of computer networks. Some are explained below
o A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school etc.
o Ethernet over twisted pair cabling and Wi-Fi are the two most common transmission technologies in use for local area networks.
o Early LAN cabling had generally been based on various grades of coaxial cable.
o Fibber-optic cabling is common for links between switches, but fibber to the desktop is uncommon.
o It stands for wide area network.
o A WAN is a telecommunications network or computer network that extends over a large geographical distance.
o Related terms for other types of networks are personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs)
o Many technologies are available for wide area network links.
o Examples include circuit switched telephone lines, radio wave transmission, and optic fibber.
o It stands for metropolitan area network.
o MAN is a network that interconnects users with computer resources in a geographic area
o Also known as a municipal area network, networking technologies used in municipal networks
o Include Asynchronous Transfer Mode (ATM), FDDI, and SMDS.
o The Metropolitan Area Network (MAN) is a publicly owned network of ducting and fibre optic cable laid in a ring formation in a metropolitan area.
Difference between LAN WAN AND MAN:
Stands for local area network
Stands for metropolitan area network
Stands for wide area network
Its connection is a high-speed connection
It is a larger network that usually spans several buildings in the same city or town.
Its comparison to a MAN, is not restricted to a geographical location,
