Study Notes

Introduction

Computer science is the operating system for all innovation
Operating system is a collection of software that manages a computer`s hardware and provides services for computer programs
OS is vital component of system software in a computer system
OS is interface between user and computer hardware
OS performs basic tasks such as file management, memory management, handling input and output, and controlling peripheral devices

Applications of Operating System

Key activities: security, error detection, control over system performance, job accounting, booting, coordination between other software and users
Security and error detection: Prevents unauthorized access; handles a variety of internal and external hardware errors such as memory error, or a device failure or malfunction
Control over system performance: Collects statistics on various resources, monitors performance parameters such as response time, recording delays
Job accounting: Keeps track of time and resources used by various jobs and users
Booting: Process of starting or restarting a computer
- Cold booting: Starting after being switched off completely
- Warm booting: Restarting the machine
Coordination: Enables coordination of hardware components, coordination of and assignment of compilers, interpreters, assemblers and other software to the various users

Firmware

Combination of firm and software
Installed directly onto hardware during manufacturing
Used to run user programs on the device
Can be thought of as the software that enables hardware to run, such as the BIOS (Basic Input/Output System)
Considered as software for hardware
Stored in non-volatile memory
Provides instructions to help hardware startup, communicate with other devices, and perform basic input/output functions.

Advantages of Operating System

Creates an abstraction, hiding details of hardware
Easy to use with a GUI
Offers an environment for users to execute programs/applications
Makes the computer system convenient to use
Acts as an intermediary among applications and hardware components
Provides computer system resources in an easy-to-use format
Acts as an intermediary between hardware and software in the system

Disadvantages of Operating System

If any issue occurs in the OS, you may lose all the contents stored in your system
Expensive for small organizations, adding a burden on them
