21. Advantages & Disadvantages Of Computer

22. Speed When data, instructions, and information flow along electronic circuits in a computer, they travel at incredibly fast speeds.

23. Reliability The electronic components in modern computers are dependable and reliable because they rarely break or fail.

24. Accuracy Despite of its amazing speed modern computer can work with almost 100% accuracy. which is very important while performing huge calculations.

25. Storage A computer can transfer data quickly from storage to memory, process it, and then store it again for future use.

26. Multitasking Multitasking is one of the major advantage of computer. Person can perform multiple task, multiple operation, calculate numerical problems within few seconds. Computer can perform trillion of instructions per second.

27. Consistency Given the same input and processes, a computer will produce the same results — consistently. Computers generate error-free results, provided the input is correct and the instructions work.

28. Disadvantages of Computer
