Document Summary

Is a computer program that gives the computer certain instructions. Can have different types of software: applications, system software. Serves as a bridge between user and computer: translates what the user wants and the computer does. Has many layers: inner most layers: kernel. Has 3 softwares: process management, memory management, device management. When devices are hooked up to the computer: these softwares determine what the computer will do next (kind of like a traf c light, second layer: services. Error detection: outer most part: the shell. The processes requisite a something form the computer. Operating system sees these requisites come in: the requisites go through stages. They are either ready: operating system decides (using a alogrithm) to decide which one goes next. Can be waiting: dont have the data needed to run it. Can be running: requisite from the computer being ful lled.
