Computer Network :))

COMPUTER NETWORKING :))

WHAT IS COMPUTER NETWORK ?

Computer network is a collection of computer and hardware's Connected by Communication that allows sharing of information's or data's.

 TOPOLOGY 

A topology describes the configuration of a communication network. The way in which the elements of a network are mapped or arranged is known as a network topology.

Ring Topology: In a ring topology, every node in the network is connected to two other nodes and the first and the last nodes are connected to each other.


Bus Topology: In this type of network topology, all the nodes of a network are connected to a common transmission medium having two endpoint


Mesh Topology: In a full mesh network, each network node is connected to every other node in the network


Star Topology: In this type of network topology, each node of the network is connected to a central node, which is known as a hub.



Tree Topology: It is also known as a hierarchical topology and has a central root node that is connected to one or more nodes of a lower hierarchy.


Hybrid Topology: Apart from these basic types, there are hybrid network topologies, which have a combination of two or more basic topologies.







THATS ALL I CAN SHARE :))))
