Computing....

 What do you mean by Computing..??
         
  One can say anything which has input - process - output scenario can be called computing.


  That's right. Computing can include calculation, comparison, gaming, data processing and many more.


  The traditional utilities like water, natural gas, electricity and telephone system is going to add one more name to its list that is "computing".


    But I am gonna discuss computing in a very large scale which includes,..

• Utility Computing
• Grid Computing
• Cluster Computing
• Distributed Computing
• Cloud Computing

   In my today's session I learnt the attributes of the above computing.

                     Computing                                          Attributes

1. Utility Computing              ----         Accessibility 
2. Cluster Computing            ----         Manageability
3. Grid Computing                 ----         Autonomic
4. Cloud Computing               ----         Performance, Scalability, Availability, Quality             of System

    The terms defined above started in 1980's with "Distributed Computing" - which is a computer system in which several interconnected computers share computer task assigned to the system.

      Some of the Computing Terms   

      A cluster is a type of parallel and distributed system, which consists of a collection of interconnected stand-alone computers working together and a single integrated computing resource.

     Parallel Computing is a form of computation in which many calculations are carried out simultaneously like 9*8-6/8*25. In this larger problems are often divided into smaller ones and then are solved concurrently.

     Grid Computing is computing which is mainly used in sharing resources, solving problems in dynamic, multi-instructional virtual organization.

     A virtual organization (VO) refers to a dynamic set of individuals or institutions defined around a set of  resource sharing rules and conditions. All these virtual organizations share some commonality among them, including common concerns and requirements, but may vary in size, scope, duration, sociology, and structure.

     The term "Cloud"  is often used as a metaphor (which makes things easily detectable) for the internet. (A simplified way to represent complicated operations..)

     Thus in simple words, we can say that, the "Cloud Computing" is a new paradigm which provides IT services which makes user's life easy when he is using different IT resources.

     I have given here an overview of different kind of computing,.. I'll post more things about this whenever I'll learn more,..
