2. What is Computing Environment? Computing Environment explains how a collection of computers will process and exchange the information to solve various types of computing problems.

3. Personal Computing Distributed computing Cloud computing Grid Computing Cluster Computing Time Sharing Computing Client Server Computing Types of Computing Environments The following are the various types of computing environments…

4. Personal Computing Environment Personal computing is a stand alone machine, the complete program resides on that machine and executed from it.

5. Time sharing Computing Environment In this environment single user can perform multiple operations at a time by using multitasking operating system. Here the processor time is divided among different tasks this is called “Time sharing”. Example, a user can listen to music while writing something in a text editor. Windows 95 and later versions of windows OS are the examples for this computing environment.

6. Client Server Computing Environment In this environment contains two machines (Client machine and Server machine), both machines will exchange the information through a application. Here Client is a normal computer like PC, Tablet, Mobile, etc., and Server is powerful computer which can store huge data, manage file, manage emails, etc., In this environment client request for data and server provides data to client.

7. Distributed Computing Environment This environment is one in which the complete functionality of a software is not on one computer but it is distributed among multiple computers. A method of computer processing in which different parts of a program are run simultaneously on two or more computers that are communicating with each other over a network Here data is distributed to different systems but they are logically related to each other.
