HARDWARE COMPONENTS- INPUT AND OUTPUT COMPONENTS In this topic we discuss the major hardware components of a microcomputer system, which are used for input, output, processing, storage, electrical supply and communication.
Most input and output devices are outside the computer case.Most processing and storage components are contained inside the case.The most important component in the case is the central processing unit (CPU) is called the processor and microprocessor.
As its name implies, the device is central to all processing done by the computer.Data received by input devices is read by the cpu , and output from the cpu is written to output devices.The cpu writes data and instruction in storage devices and performs calculation and other data processing.
Whether inside or outside the case and regardless of the function the device performs,each hardware input, output, or storage device require these elements to operate:
A method for the CPU to communicate with the device
·The device send…
