The bus system is kinda easy. It was like a glue which link everything together.
First, there is a System Bus which connects CPU with main memory, I/O & etc. There are some term that u need to understand.
A Bus is a communication pathway connecting plenty of devices.
Peripheral Devices means unrelated devices other than CPU those.
Bus clock pulse is a time reference for attached devices.
Data transfer rate is the rate which transmitted through a medium.
Bus protocol is the format, content, time of data & etc.
Here an example is how buses flows. Each of the devices will pass through 3 type of lines.
