INTRODUCTION TO COMPUTING CS101

Q: 1

Computer Description Cost Performance Reliability Size Installed In Numbers

Super Computer:

 These are very expensive and have high cost. Used for special Purpose. These computers are not reliable like main frame computers. It takes a acres of land du to its big size. Vary fast computers. As discussed these are computers are for some special purpose so these are small in numbers.

Main Frame:

 Main frame computers are also have high cost and have good speed and vary fast . These computers are used on backbones of internet.  Due to its limited size these computer are much reliable than super computers. These computer used frequently in different place so these are more than super computer Personal Computers:

 These are low cost computers. Used vary common in our life in offices, departmental stores, labs, pharmaceutical etc.  Almost every organization has these computers. These computers are cost effective so these are found in millions and trillions in the world

PDA’s:

 These are small in size. Cost is higher than personal computer. Used for some specific purposes. These are also available in large number

Differentiate Between Static RAM and Dynamic RAM in Tabular form. ANY TWO Differences

Dynamic Ram

1)  Most common type of ram used now –e days.

2) Data/Information stored on single memory chip which is made of two parts transistors and capacitors.

3) Data stores in form of 1 and o.

4) It stores information’s in more quantity than static Ram.

5) It looses its previous instruction when new ones are loaded in.

6) It refreshes it self and loose the old instructions.

7) It is comparatively slow because it refreshes itself

Static Ram

1)  Static ram is expensive then dynamic ram

2)  It stores information in form of Flip Flop

3)  It access the information vary fast.

4) No need for refreshing.

5) More faster Ram then Dynamic Ram
