Job sequence in operating system

Answer 1

There is no job sequence in the since of the word. Whatever applicaton you open or what you click on it is done one right after the other. When you press a keyboard key the signal goes to the CPU and the CPU tells the memory controller chip I need this line of programming from RAM to pull of this request. The memory controller pulls it out of RAM and gives it to the CPU on an address bus. Then the CPU processes it and send out the data on the data bus. All this happens billion times a second. For instance a 1.2GHz CPU processor is processing 1.2 billion processes a second.
