Document Summary
Hardware runs the software but software does all the stuff y compu programs y major categories of software. The stored program idea is what makes the compu such a powerful tool: don t need to build new hardware every time u want to do something new. It took considerable genius to come up with the stored program idea: >in and around the same time many others had a similar idea: zuse, eckert and mauchly, >based on notes she made about the analytic engine. >she was fairly well to do cuz she had a painting of her. Compu programs are (ultimately) described in a machine lang. A lang of 1s and 0s (binary #s) >special low-level arithmetic and logical operations (can differ depending on machine architecture) Programmer writes a program to solve tasks and it is stored in memory. >compu retrieves the program from memory and carries out the instructions in the program. Wrote compu languages closer to the programming lang.
