What are the types of network topology?

Linear bus topology- is a type of network topology in which each device is connected one after the other in a sequential chain (shown right). In this case, the bus is the network connection between the devices, and if any link in the network chain is severed.
Star Topology- uses a central device called a hub (a more efficient device called "switch" is also used) with cables extending in all directions.

Ring Topology- is a tube of network topology where in nodes are connected to each other forming one.

Mesh Topology- are structures where in all the nodes on the network can route data traffic on their own.
Hybrid Topology- uses a mix of any two or more different topologies in such a way that the final work does not exhibit on of the characteristics of the standard topologies.

What are the types of computer network?

LAN- (Local Area Network)
local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment.


MAN- (Metropolitan Area Network)
A metropolitan area network (MAN) is a computer 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).



PAN- (Personal Area Network)
A personal area network is a computer network for interconnecting devices centered on an individual person's workspace. A PAN provides data transmission amongst devices such as computers, smartphones, tablets and personal digital assistants.




WAN- (Wide Area Network)
A wide area network is a telecommunications network or computer network that extends over a large geographical distance/place. Wide area networks are often established with leased telecommunication circuits.
