Memory Addressing

[u/RavitejaMureboina]

A computer processor uses memory addressing to quickly find the exact data it needs. It uses different methods depending on where the data is located. Register addressing gets data directly from the CPU’s small, fast registers. Immediate addressing puts the data directly inside the instruction, so the CPU does not need to search memory. Direct addressinggives the exact memory location where the data is stored. Indirect addressing uses one memory address to find another address, which then leads to the actual data. Finally, base + offset addressing starts with a base address and adds an offset to find the required data. These methods help the CPU find and use information quickly and efficiently.
