Information processing cycle

[marcoper]

Do the four operations in the information processing cycle (input, process, output, storage) always have to be performed in order. Why or why not?

[iisbob]

Can you be alittle more specific in your question?

Are you asking about CPU performance? A specific program software performance? A specific piece of Hard ware performance { ie, memory }?

What about this subject do you already understand? What specific questions do you have?

Have you tried Charles PCGuide (http://www.pcguide.com)? look around the guide for a bit and then if you have any further question's feel free to post them; but try a little research first.

Thanks iisbob for responding me. I'm taking INtroduction to Computers at college, and they gien me this quiestion as an assignment. I think that tha processing information cycle always go from input to processing to output an finally to storage. Bur if you put as cd-rom disc and open a file you are atarting on storage rigth? and from there you go to input since the memory will read the information process it and the show it in your monitor as output? Then the sequence will be storage-input-processing-output. Is this right? Then the information processing cycle ALWAYS is performed in order?? (Sorry but I am just a beginner)
Thanks

No, the reading of data from a CD is called the "input" stage. The fact that the data is coming from a storage device and not being inputed from the keyboard is not important. What is important is that the data to be worked on is being brought into the process cycle.

A more detailed sequence would be :


Acquisition
Input
Validation
Processing
Storage
Retrieval
Output
Communication
Archiving ( or "Storage" in your classes lingo)


You might not use all "stages" of the cycle but they are always in that order.


Look here for the reasoning behind the "cycle":
