1) Speed:-
Computer performs complex calculation at a very high speed. This speed varies from a few micro second to nanoseconds. This is the major factor, which is mainly responsible for the development of computers.
Fractions of a Second:
1 Millisecond = 1/1000th of a second (10-3)
1 Microsecond = 1/1000000th of a second (10-6)
1 Nanosecond = 1/1000000000th of a second (10-9)
1 Pico second = 1/1000000000000th of a second (10-12)
2) Accuracy:-
Computer do not make mistakes. Computer always given 100% actual output, if the user provides correct input and instructions. If any mistake occurs in any calculation they are due to manual error but not of computer.
3) Storage:-
The computers have very large storage capacity. The stored information also can retrieve immediately. This helps in analyzing data and taking quick decisions.
Computer store data in terms of memory units
0 or 1 = 1 Bit (Binary Digits)
8 Bits = 1 Byte
1024 Byte = 1 KB (kilobyte)
1024 KB = 1 MB (megabyte)
1024 MB =1 GB (Gigabyte)
1024 GB = 1 TB (Terabyte)
4) Versatility:-
Computers are being used in different fields such as business, offices, school, hospital, etc. to perform various tasks. Versatile means ability to perform various task an computer can capable to do so. A computer can process any kind of data.
5) Diligence:-
Diligence is capability of performing repeated operation without any tiredness any mistakes. A computer is capable of performing the required task continuously with the same speed, accuracy and efficiency without any error. This characteristic of computer makes it useful for repetitive jobs like process control and quality control.
6) Reliability:-
Computer output is generally very reliable, if the input data and instruction is correct. Incorrect data and unreliable programs gibe us computer errors and wrong results. Since the computer is 100% accurate, it is reliable.
