After knowing how does CPU works,
we'll proceed to how CPU Communicate with(or you can say
"control") the
peripheral divices.
Let's have a look in the I-P-O(Input-Procees-Output) first.
- Input is the input of data from input unit
- Process is computing and proccessing the data by the "intelligence" of the machine
- Output is output of information by output unit
You should not think that data is not equal to information. Data is raw material while information is processed output.
Computers, like other machines, follow the I-P-O process. Now, we'll have a look in how does CPU control the periheral devices.
- The Control Unit send control sign to peripheral devices and other part of CPU. Control signal is sent via control bus
- Various part of computer exchange data/information via data bus
