Characteristics of Computer 1

Computer… : 

Computer… Comes from the word “compute” Compute means “to calculate” So Computer is calculating device Perform calculations at enormous speed Computer is device that operates upon “Data” or “Information” e.g. preparing results, calculations, transactions, scientific work etc 2

Computer… : 

Computer… Computer can input “Data” Computer can process “Data” Computer can store “Data” Computer can retrieve “Data” Finally… Computer can be termed as “Data Processor” 3

Characteristics of Computer… : 

Characteristics of Computer… Speed Accuracy Diligence Versatility Power of remembering No I.Q. No Feeling Reduction in cost 4

…Characteristics of Computer…Speed… : 

…Characteristics of Computer…Speed… Fast device Work done at enormous speed as compare to human beings Speed of computer is measured in terms of microseconds (10-6), nanoseconds(10-9) and even picoseconds (10-12) Shortly 3 to 4 million simple arithmetic operations per seconds 5

…Characteristics of Computer…Accuracy… : 

…Characteristics of Computer…Accuracy… Works with the highest Accuracy Accuracy depends upon the “Design of Computer” Errors occurred are mostly “Human Errors” rather than “Technological Errors” Human Errors are like wrong command, inaccurate data input etc 6

…Characteristics of Computer…Diligence… : 

…Characteristics of Computer…Diligence… Free from “Monotony” Free from “Tiredness” Free from lack of “Concentration” Speed and Accuracy of first calculation will be the same as millionth calculation in a row 7

…Characteristics of Computer…Versatility… : 

…Characteristics of Computer…Versatility… Can perform all kind of job simultaneously Can do diverse nature of works like calculation, graphic work, searching etc at the same time 8

…Characteristics of Computer…Power of Remembering… : 

…Characteristics of Computer…Power of Remembering… Unlike human being Computer can store tremendous/huge amount of data Can recall required data even stored years before in no time Doesn't differentiate “Important” & “Not Important” Loss or Deletion of data is done by User 9

…Characteristics of Computer…Reduction in cost… : 

…Characteristics of Computer…Reduction in cost… Initial investment is high Reduce the cost of each transaction Reduce the man power and space requirements Greater efficiency 10

…Characteristics of Computer…No IQ… : 

…Characteristics of Computer…No IQ… Not a thinking machine Not Intelligent Never does a task at its own Follow human Instructions 11

…Characteristics of Computer…No Feeling… : 

…Characteristics of Computer…No Feeling… Follow human/programmer Instructions Never decides at its own will No taste No knowledge No emotion 12
