Document Summary
Isa instruction set architecture concerned with the register set, instruction set, and addressing modes assembly language embodies isa. Computer organization is concerned with the implementation of an isa computer organization tells you how a computer does it computer architecture tells you what a computer does. Cpu (central processing unit) reads instructions and execute them, microprocessor. Bus is data highway and moves information around. There are two types of computers, dedicated and general, for general computers, its program and data are held in the same memory. The register a memory element that holds one unit of data, no difference between register and a word in the memory, located within cpu. The clock computer travel on electric pulses, synchronous and asynchronous. Memory hierarchy - registers -> cache -> dram -> hard disk. Range: variation between the largest and smallest values that can be represented by a number precision: how well we can represent the number.
