What is a computer? A computer is a device capable of performing computations and making logical decisions at speeds millions (even billions)of times faster than human beings can Computers process data under the control of sets of instructions called computer programs. These programs guide the computer through orderly sets of actions specified by people called computer programmers A computer consists of various devices referred to as hardware(e.g, the keyboard, screen, mouse, hard disk, memory, DVDs and processing units). The programs that run on a computer are referred to as software

Computer Organization Input unit. This is the receiving section of the computer. It obtains information (data and computer programs) from input devices and places this information at the disposal of the other units for processing Output unit. This is the shipping" section of the computer. It takes information that the computer has processed and places it on various output devices to make the information available for use outside the computer Memory unit. This is the rapid-access, relatively low-capacity warehouse" section of the computer. It stores computer programs while they are being executed
