The techniques specified in the ISA to determine where the data operands for an instruction are located (e.g., in registers or main memory).
The distinction between these two concepts is fundamental to understanding modern computing systems. Computer Architecture Computer Organization High-level system design and behavior. Low-level physical components and interconnections. Visibility Directly visible to the assembly programmer. Transparent/hidden from the programmer. Core Elements COMPUTER ORGANIZATION AND ARCHITECTURE
Instruction Set Architecture (ISA), data types, and addressing modes. Control signals, memory technology, and bus structures. The architectural blueprint of a house. The techniques specified in the ISA to determine
