CPU Internal Organisations The input/output (I/O) interface, bus structures, microprocessor, memories and peripherals (also known as external or I/O devices) are the major components of a computer system. These components constantly trade information and instructions to complete assigned operations. With the exception of the peripherals, the ongoing communication between components is conducted within the system through interconnections or paths called buses. Peripherals such as keyboards, add-in cards (including frame grabbers), monitors, modems …showed first 75 words of 474 total…

The clock speed is measured in megahertz and the path size is measured in bits. The transfer rate brings these two variables together to represent how much and how fast data is moving at any given time. The transfer rate is usually indicated in megabytes per second.
