1. A computer can store or handle any data even if it hasn’t received instruction to do it. 2. All computers accept and process information in the form of instructions and characters. 3. The information necessary for solving problems is found in the memory of the computer. 4. All computers can perform arithmetic operations, make decisions, and communicate in some way with the user. 5. A computer can do everything without any person’s interference. 6. Electric pulses moving at the speed of light a computer can carry out vast number of arithmetic-logical operations almost instantaneously. 7. A person cannot do the same, because his life is too short. 8. Computers have circuits, which can make decisions. 9. The kinds of decisions which computer circuits can make are not of the type: Is one number less than another?, Are two numbers equal? and Is one number greater than another?; but of the type: 'Who would win a war between two countries? ' or 'Who is the richest person in the world?'. 10. A computer is a machine with an intricate network of electronic circuits that operate switches or magnetize tiny metal cores. 11. The switches are capable of being in one possible magnetized state. 13. The digital machine is capable of storing and manipulating numbers, letters, voltages and characters. 14. The basic idea of a computer is that we can make the machine do what we want by outputting signals that turn certain switches on and turn others off. 15. The basic job of computers is the processing of information. 16. The program provides the information needed to solve the problem and the data tells the computers what to do. 17. They are kept inside the computer in a place called memory. 18. Computers are thought to have many remarkable powers.
