What is the difference between input&output devices?
Input and output devices are usually referred to as the I/O devices. In order for a fully functional computer system, both input and output hardware types must be installed and operational.Hardware DevicesAlthough a hardware device is important to the operation of a computer, without instructions to control and accomplish tasks, the hardware components are useless. The central processing unit (CPU) is the brain, which communicates with the input, output and storage devices of the computer–circuitry that interprets and executes instructions. With the help of the main memory, the CPU executes the instructions in the repetition of machine cycles.The Input ProcessThe input process begins with entered information into a computer system through an input device. The entered information is then stored in the main memory temporarily. The control unit (CU), through sent signals and commands, receives instruction from the main memory, and then the CU sends signals and commands to other parts of
