Speed: Computer performs complex calculation at a very high speed. This speed varies from a few microsecond to nanosecond. 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)
Accuracy: Computer do not make mistakes. Computer always given 100% actual output (result),if the user provides correct input and instructions. If any mistakes occur in any calculation they are due to manual error but not of computer. Since it is 100% accurate, it is reliable.
Storage: The computers have very large storage capacity. The stored information also can retrieve immediately. That helps to analyzing data and taking quick decisions.
Computer Store data in terms of memory units
0 or 1 = 1 Bit (Binary Digits)
8 Bits = 1 Kilobyte (KB)
1024 Byte = 1 Megabyte (MB)
1024 KB = 1 Gigabyte (GB)
1024 GB = 1 Terabyte (TB)
Versatility: Computers are an electronic device which we can used in different fields such as School, Science and Technology, Hospitals, Offices, Government, Industry etc, to perform various tasks. Ability to perform various task and computer can capable to do is called versatile. A computer can process any kind of data.
Diligence: Capability of performing repeated operation without any tiredness and any mistakes are known as Diligence. 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.
Reliability: If we can input data and instruction correctly then computer output is generally very reliable. If there is incorrect data and unreliable programs input then they gives us computers errors and wrong results since the computer is 100% accurate, it is reliable.
