Document Summary

Processor: device that does actual computing (follows program instructions) Equivalent terms in common use are computer, microprocessor, central processor, Operating system: software that makes computer into useful device. Splash screen is an image that displays before an application starts running. Fetch/execute cycle: implemented in hardware- consists of getting the next instruction, figuring out what to do, gathering the data needed to do it, doing it, saving the result, and then repeating the cycle again and again. Anatomy of computer (5 parts): memory, control unit, arithmetic/logic unit, input unit, output unit. Memory: stores program while running and data on which program operates. Discrete location-memory organized as sequence of discrete locations each location made of on byte (8 bits) Addresses-every memory location has address, whole numbers starting at 0. Finite capacity-limited size. (memory) words: blocks of 4 bytes. Random access memory (ram): random access means computer can refer to the memory locations in any order.
