You've got punch cards, a CPU and memory.

I see the memory operating, I see the CPU operating,

Co processor 8 bit Zilog Z80 Memory 32 kilobyte 96 kilobyte VRAM (internal CPU), 256 kilobyte DRAM (external CPU).

This family has five CPU registers that are not part of the memory.

There's this incredible complexity in the CPU, and this incredible regularity in the memory.

I have behind this wall a disk drive, a CPU, a graphics card, a memory system.

And then the CPU has to ask memory for the program for the button, which means that the CPU needs the monitor program again to show the video associated with the button, and so it goes.

Main memory A PC's main memory is a fast primary storage device that is directly accessible by the CPU, and is used to store the currently executing program and immediately needed data.

Because the CPU learns that the mouse was clicked when the cursor was over a picture of a button on the monitor screen, and so, the CPU asks memory for the monitor program to find out what that button is.

Many CPU architectures instead use so called memory mapped I O, in which a common address space is used for both RAM and peripheral chips.

So the bus diligently carries the data into the computer to the memory, to the CPU, the VRAM, etc., and it's an actual working computer.

I read about how the CPU is constantly shuffling data back and forth between the memory, the RAM and the ALU, the arithmetic and logic unit.

Divide CPU usage by number of CPUs

The current CPU usage of the process.

And here's RAM and here's the CPU.

The current total CPU usage of the process.
