35 likes18,431 views
This document provides an overview of operating systems and their components. It discusses hardware (1), firmware (2), and software (3) as the main parts of an operating system. Firmware includes the BIOS that initiates the boot process. Software is divided into firmware, operating systems, and applications. The document then discusses the boot process (A-F) and describes different types of software: operating systems, device drivers, anti-virus software, and productivity applications. It also covers user interfaces, both command-line interfaces (CLIs) and graphical user interfaces (GUIs).
