Ok on the 19th edition on page 68 and give or take a few pages depends on the book. You talk how the CPU Cache L1 L2 & L3 cache works & Ram and hard disks & food.

Now how dose the graphics Card fit into this.

My guess would be It would go the Graphics card ask the CPU for instructions Kinda like the Boss (CPU) telling worker (GPU) what to do. then the graphics card would collect the info from the hard drive or SSD drive. Save most of it on the GDDR ram on the graphics card then the rest to the DDR Ram what ever is left over is on the Hard drive or SSD drive. While collecting instructions from the CPU.

So with a 32 bit OS. The cpu & graphics card Shares the 4 gb ram (Company Resource) or and has to access the Hard drive or SSD drive?

Vs

64 Bit OS which means a Larger company so 4 or 8 gb Ram or more (Company Resource) It would have more room for the Ram from both CPU and Ram so less access to the hard drive. So less access to the SSD Drive or Hard drive?

The graphics card or GPU (Graphics Processing Unit) is like a subordinate co-worker to the CPU. The processor feeds it commands and data, and the GPU does what it is told to paint pictures on the screen. In the restaraunt analogy I might think of the GPU as an in-house sign controller who is at the controls of a jumbotron type display outside the restaraunt, constantly changing the display as requested.

The GPU does not access the hard drive or RAM directly, it can only be fed data from the CPU or from other devices on the bus. It would work essentially no differently whether the CPU was running either 32- or 64-bit code. Scott.

Ok so the CPU controls the Ram and hard drive info and the cpu hands Info to the graphics card when needed.
