What is the hierarchy of memory? It's not clear why the writers made it a pyramid.

How is dynamic memory distinct from static memory, and what does it entail, exactly?

You will learn more about memory hierarchies and how they operate in this section. Is there a particular reason why your writers picked a pyramid to symbolize their work visually?

Imagine we have a small computer which contains a simplified version of a CPU and RAM. The CPU can execute a single program that is stored in the RAM, and while running the program it can access 3 memory locations: its internal register AL, and two RAM locations that we'll call address 1 and address 2. Since this is a simplified computer it is able to skip some of the steps to access memory that are in our textbook, but accessing RAM still takes longer than accessing AL. The only values this computer is capable of storing in memory are unsigned bytes (8 bit binary numbers), and when it starts running a program all 3 of its memory locations initially contain the value 00000000.  Here is a list of all of the instructions our imaginary computer can perform: Write [number] to AL This instruction takes the operand [number], which must be an 8-bit binary number, and puts it into AL. This overwrites whatever was in AL previously. It takes 3 cycles to complete: 1 cycle each to fetch, decode,…
