instruction and data memory; the effect of executed instructions on the registers and memory;
and an algorithm for controlling instruction execution.Examples of architectural attributes include the instruction set,
the number of bits used to represent various data types (e.g., numbers, characters), I/O
mechanisms, and techniques for addressing memory.Data processing
