Study Notes

Registers and Cache Memory

Main memory stores program instructions and data.
Cache memory is located inside the processor and is faster than main memory.
There are different levels of cache memory, with Level 1 being the fastest and smallest, and Level 2 being larger but slower.

Secondary Memory

Secondary memory refers to storage devices that contain persistent data.

Functional Units

FPU (Floating-Point Unit): Performs arithmetic operations on floating-point numbers, similar to the ALU.
ALU (Arithmetic Logic Unit): Contains circuits for binary arithmetic and logical operations.

Programming Languages and Tools

Assembly Language: Uses human-readable symbolic instructions and addresses to represent machine language instructions.
Assembler: Converts assembly language programs (source code) into machine language.
Compiler: Translates the entire source program into machine language.
Interpreter: Translates each instruction in the source code only when it is required for execution.
