The CPU processes calculations that are in the programs. It takes billions of calculations just to have a start menu and desktop background.

CPU is the processor and receives instructions from:
All Input/output devices such as: Floppy disks, hard drives, CD rom drives, jump drives, zip drives, keyboards, mice, etc, etc.
It also receives instructions from memory, and instructions from the BIOS (Basic Input Output System) which is stored on your system board.
Most of the information is stored on the hard drive, such as the operating system and programs as well.

The CPU has an "instruction set" (a way of reacting to the external world) built in. It also has, built in, a set of connections to the external world: paths for input, paths for output - nerve paths, to compare to a human brain, if you will. Humans send input to that brain, input being things to which the CPU should react, or "instructions" via one of these built-in paths. "Hey you! Add two and two, two times over and over again, until I tell you to stop! Okay, stop!" "Hey, Add, Over, and Stop" are items from the "instruction set".

Hi
The applications like word and excel refer their inquiries to the CPU. It carries out the calculations and passes the answer back to the application.
So when your poota seems slow the processor is having a bad hair day.
RAM is also important but that will have to wait for later on in my series of winter lectures
Thank you

The program on the HD, sends data to the memory, then the memory sends data to the CPU. The CPU send data back to the memory, then it is sent back to the HD.
This happens billions of times per second, defined as Nanoseconds, which is one billionth/second.
