Computers are used in many fields including business, education, manufacturing, transportation, banking, agriculture, government, health, communication, and scientific research. They are fast, accurate, versatile, diligent, and can store huge amounts of data. While computers have no intelligence of their own and require human-made programs, they can process instructions and calculations rapidly without errors, take on multiple tasks simultaneously without tiring, and reliably store and retrieve large amounts of information.

1. Application of Computer

2. • Businesses

4. Characteristics of Computers
• Speed
The speed of the computer is measured in terms of
instruction processed per second
• Accuracy
In the case of human, one could commit approximately
one error for 500-1000 calculations’ computer commits
no error and has the same efficiency with any amount
of data.
• Versatility
• The property of a computer to do more than one work
at a time is called versatility

5. • Diligence
In the case of human can tired when multiple
task are doing simultaneously. but the Computer
do not suffer from stress and strain and do not
get tired .this is called diligence.
• No IQ: it cannot work itself. Computer need
programs to do a work, this program are made by
humans.
• Storage capacity: huge amount of data can be
store.
