1.2 what is computer?
a comuter is adivice capable of performing computations and making logical decisions at speed millions and even billions of times faster than human biengs.for example:can you calculate 4000874562892097484003947+64537873874768327466000857+64572854567783882354785688=?
computer can calculate this question 0.2seconds but you can calculate 20-30 minute.
1.3 computer orgianization
