Document Summary

Fetch/execute cycle (machine cycle: instruction fetch, instruction decode, data fetch, instruction execute, result return. Stores the program while it"s running, and the data in which it operates by. Fetches an instruction from memory and performs other operations of the fec. Comp interpreting at the addition of two numbers. Does not add 200 and 2080, it simply just adds the numbers stored in those two units, and stores the result in 4000. Logic gates: simples circuits that implement operations like and & or. Generally does the work during the instruction execute step of fec. Data fetch gets the values(aka operands) from memory that the alu needs to perform operations like add and multiply. Wires and circuits through which information moves into and out of a computer. Used to communicate w/ the two components that do the calculations and complete the operations.
