This document summarizes key aspects of system software, including operating systems, graphical user interfaces, booting processes, types of operating systems, and common troubleshooting utilities. It outlines the main functions of operating systems like coordinating computer resources and providing an interface between users and applications. It also describes different types of operating systems like embedded, network, and stand-alone and provides examples like Windows, Mac OS, and Unix. Finally, it discusses system troubleshooting tools for tasks like antivirus protection, backup, disk cleanup, and device drivers.
