Document Summary

Requires memory, processor, ability to perform basic functions, ability to manage / coordinate all sub-systems. Store programs and data, execute steps sequentially, produce output from input. The way hardware components in a computer interact and communicate. Hardware: cpu, memory, busses, clocks, peripherals computer built out of. A model for designing and building computers based on 3 characteristics: contains 4 major subsystems: memory, i/o (input / output), alu (arithmetic / logic unit), cu (control unit, has stored program concept, follows sequential execution of instructions. Additional components: motherboard, bus (communication lines), clock (regulates time / speed), registers, flip-flops . Alu performs integer arithmetic (addition / subtraction) and logic operations (boolean. Cu is the master conductor of all operations including reading and interpreting instructions, sequencing the processing of data, responsible for moving data between alu and memory, has instruction set of all possible instructions that may be asked to perform.
