| + | We saw that the memory is a huge collection of boxes containing bits. We called these boxes ''words''. In general a word is partitioned into one or several bytes. A byte is a group of 8 bits and is used as a unit of data storage. Each memory word contains either instructions or data. We refer to data memory words in assembly language as ''variables''. The way the processor works, it constantly fetches an instruction from memory (RAM) and executes it. Most of the time, the instruction makes the processor transfer binary information between a variable in memory and the '''AC''' register. Executing an instruction takes '''one processor cycle'''. | ||
