Computing Environments

  • Difficulty Level : Medium
  • Last Updated : 15 Oct, 2020

In the world of technology where every tasks are performed with help of computers, these computers have become one part of human life. Computing is nothing but process of completing a task by using this computer technology and it may involve computer hardware and/or software. But computing uses some form of computer system to manage, process, and communicate information. After getting some idea about computing now lets understand about computing environments.

Computing Environments :
When a problem is solved by the computer, during that computer uses many devices, arranged in different ways and which work together to solve problems. This constitutes a computing environment where various number of computer devices arranged in different ways to solve different types of problems in different ways. In different computing environments computer devices are arranged in different ways and they exchange information in between them to process and solve problem. One computing environment consists of many computers other computational devices, software and networks that to support processing and sharing information and solving task.

Based on the organization of different computer devices and communication processes there exists multiple types of computing environments. Now lets know about different types of computing environments.

Types of Computing Environments :
The are the various types of computing environments. They are :

Computing Environments Types

  1. Personal Computing Environment :
    In personal computing environment there is a stand-alone machine. Complete program resides on computer and executed there. Different stand-alone machines that constitute a personal computing environment are laptops, mobiles, printers, computer systems, scanners etc. That we use at our homes and offices.
  2. Time-Sharing Computing Environment :
    In Time Sharing Computing Environment multiple users share system simultaneously. Different users (different processes) are allotted different time slice and processor switches rapidly among users according to it. For example, student listening to music while coding something in an IDE. Windows 95 and later versions, Unix, IOS, Linux operating systems are the examples of this time sharing computing environment.
  3. Client Server Computing Environment :
    In client server computing environment two machines are involved i.e., client machine and server machine, sometime same machine also serve as client and server. In this computing environment client requests resource/service and server provides that respective resource/service. A server can provide service to multiple clients at a time and here mainly communication happens through computer network.
  4. Distributed Computing Environment :
    In a distributed computing environment multiple nodes are connected together using network but physically they are separated. A single task is performed by different functional units of different nodes of distributed unit. Here different programs of an application run simultaneously on different nodes, and communication happens in between different nodes of this system over network to solve task.
  5. Grid Computing Environment :
    In grid computing environment, multiple computers from different locations works on single problem. In this system set of computer nodes running in cluster jointly perform a given task by applying resources of multiple computers/nodes. It is network of computing environment where several scattered resources provide running environment for single task.
  6. Cloud Computing Environment :
    In cloud computing environment on demand availability of computer system resources like processing and storage are availed. Here computing is not done in individual technology or computer rather it is computed in cloud of computers where all required resources are provided by cloud vendor. This environment primarily comprised of three services i.e software-as-a-service (SaaS), infrastructure-as-a-service (IaaS), and platform-as-a-service (PaaS).
  7. Cluster Computing Environment :
    In cluster computing environment cluster performs task where cluster is a set of loosely or tightly connected computers that work together. It is viewed as single system and performs task parallelly that’s why also it is similar to parallel computing environment. Cluster aware applications are especially used in cluster computing environment.
