CHARACTERISTICS OF A COMPUTER & CENTRAL PROCESSING UNIT (C.P.U)

Hello, Readers This Blog will help you understand the Characteristics of Computer & About C.P.U (Central Processing Unit ). Characteristic means Computer capabilities i.e Characteristics of Computer 1.Speed 2.Accuracy 3.Consistency 4. Data Storing Capability 5.Flexibility A. Speed : A Computer is a very fast device .It can perform , in a few Second ,the amount of work that a human being can do in an entire year working round the clock .The speed of the computer is usually 2 to 4 GHz . A powerful computer is capable of performing about 10 to 40 million arithmetic calculations in a second. or We can say that Computer speed is measured in megahertz (MHz) or gigahertz (GHz). One Megahertz equals to one million ticks per second,one Gigahertz equals one billion ticks per second . B. Accuracy : The accuracy of a Computer is consistently high an the degree o accuracy of a particular task is 100% accurate.In a every computer each and e...
