WHAT ARE THE TYPES OF NETWORK TOPOLOGY?

LINEAR BUS TOPOLOGY
bus topology is a network setup in which each computer and network device are connected to a single cable or backbone. The device is connected one after the other in a sequential.




MESH TOPOLOGY
     Mesh topology is a type of networking where all nodes cooperate to distribute data among each other.  This topology was originally developed 30+ years ago for military applications.

RING TOPOLOGY
ring topology is a network configuration in which device connections create a circular data path. Each networked device is connected to two others, like points on a circle. Together, devices in a ring topology are referred to as a ring network.

STAR TOPOLOGY

Star topology is one of the most common network setups. In this configuration, every node connects to a central network device, like a hub, switch, or computer. The central network device acts as a server and the peripheral devices act as clients.

HYBRID TOPOLOGY
Hybrid topology is an integration of two or more different topologies to form a resultant topology which has many advantages (as well as disadvantages) of all the constituent basic topologies rather than having characteristics of one specific topology.

WHAT ARE THE TYPES OF COMPUTER NETWORK?

Personal Area Network (PAN)

A personal area network (PAN) is the interconnection of information technology devices within the range of an individual person, typically within a range of 10 meters. They typically involve a computer, phone, printer, tablet and/or some other personal device like a PDA.

Local Area Network (LAN)

A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.

Metropolitan Area Network (MAN)

A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).

Wide Area Network (WAN)

A wide area network (WAN) is a network that exists over a large-scale geographical area. WANs are used to connect LANs and other types of networks together so that users and computers in one location can communicate with users and computers in other locations. Many WANs are built for one particular organization and are private.
