In general we have 4 kinds of computing environments.
1. Personal Computing Environment
2. Time Sharing Computing Environment
3. Client/Server Computing Environment
4. Distributed Computing Environment
1. Personal Computing Environment
The Combination of basic elements of central processing unit and microprocessor is Personal Computing Environment or simply Personal Computers.
These kinds of environments are designed to be used by one user at a time.
2. Time Sharing Computing Environment
In this environment all the computing and processing must be done by Central Computer which is a sharing resource by means of time. Such as Multi Tasking and Multi Programming.
3. Client/Server Computing Environment
It involves the processing between two machines. A Client Machine is one which requests processing. A Server Machine is one which offers processing.
Examples: WWW, Email, etc.,
The core processing is done by server so that the client is capable enough to do a portion of processing.
4. Distributed Computing Environment
Distributed computing is a de-centrally controlled computing
environment where a large number of heterogeneous
computing resources are interconnected in the geographical
space through high speed network.
A DCE provides an integration of computing functions between different servers and clients. A Client is not just a requester for processing the information from the server. The client has also the capability to process the information. All the machines(client/server) share the processing tasks.
