Computer System Summary and How the Processor Components Work Together
There are two processor components in the Five Classic Components of a Computer. Datapath and Control. Hardware and software work together to perform tasks within the
processor. The software provides instructions to be completed by the
hardware.
In this context, the processor hardware consists of the CPU registers and memory where operations are executed. The software is assembly language code that is converted to machine code instructs the hardware processing.
There are layers of software that ultimately controls the circuit boards. These layers consist of high-level languages, assembly code, machine language code, etc. Software can be run on any layer of the computer system level hierarchy depending on what tasks are being performed by the system.
At the lowest level software is converted to basic machine language that is managed by the Control layer and executed in the digital logic layer in the Datapath. This enables data processing.
