- Automation means ability to perform the given task automatically.
- Once a program is given to computer i.e. stored in computer memory, the program and instruction can control the program execution without human interaction
6. Speedy(speed)
- Computer is a very fast device.
- It is capable of performing calculation of very large amount of data.
- The computer has units of speed in microsecond, nanosecond, and even the picosecond.
- It can perform millions of calculations in a few seconds as compared to man who will spend many months for doing the same task.
7. Accuracy (Accurate)
- An addition to being very fast, computers are very accurate.
- The calculations are 100% error free.
~Computers perform all jobs with 100% accuracy provided that correct input has been given.
