Network Computing Models




Network computing models


Centralized Computing or Client Server Model

In Centralized Computing model multiple computers are joined to one powerful mainframe computer called server.

The devices those are connected to server are called nodes or clients.

Server is a high end computer with huge storage and high processing capabilities.

A server host runs one or more server programs which share their resources with clients.

A client does not share any of its resources.

Clients initiate communication sessions with servers by sending a request.

Applications that use the client–server model are Email, network printing, and the World Wide Web.

Distributed Computing:

In distributed computing:

Every task needs to be split into pieces — the data and the corresponding tasks need to be distributed.

All the nodes are capable of processing on their own.

All the nodes are connected to each other.

Example of distributed computing

ü  WhatsApp: data needs to be sent to multiple mobile simultaneously and fast.

 

ü  Twitter can deliver tweets to my followers so fast.


 ü  Instagram can store so many images.

Hybrid Computing/ Collaborative Computing.

It is combination of centralized and distributed computing.

In hybrid computing the nodes are dependent on some other computers to serve specific request.
