Operating Systems Lesson Quiz

Study Notes

Introduction to Operating Systems

Booting instructions are stored in Read Only Memory (ROM).
Booting is the process where the CPU reads the Master Boot Record (MBR) from the boot drive and loads the Operating System into Random Access Memory (RAM).
An Operating System (OS) is essential software that serves as an interface between the user and the computer hardware.

Functions of an Operating System

Manages computer hardware, enabling users to utilize various functions of the machine.
Acts as a mediator between application software and hardware components.

Types of Software

System Software: Includes the Operating System and Utility Software that help in managing and maintaining computer resources.
Application Software: Designed for end-users to perform specific tasks (e.g., word processing, spreadsheets, databases, web browsers, computer games).

User Interfaces of Operating Systems

Various types of user interfaces offered by operating systems include command-line interfaces and graphical user interfaces, enabling users to interact with the computer easily.

Services Provided by Operating Systems

Facilitates services such as file management, process management, memory management, and device management, ensuring smooth operation of the computer.

Types of Operating Systems

Operating systems can be categorized based on their architecture and usage, including batch, real-time, multi-user, single-user, and distributed operating systems.

Advantages of Operating Systems

Streamlines user experience by providing an interface for executing tasks.
Enhances system performance by efficiently managing resources and processes.

Utility Programs

Utility Software supports the operating system by performing maintenance tasks (e.g., virus scanning, file compression, disk management) to keep the system running optimally.
