Study Notes

Computer Software

Computer software refers to a collection of data or instructions that instruct a computer on how to work.
Software can be categorized into two main types:
System Software
Application Software

System Software

System software is designed to provide a platform for other software.
It consists of the operating system (OS) and utility programs.
Operating system (OS) is the most essential software that manages computer hardware and provides services for computer programs.

Operating Systems (OS)

Functions of an OS:
Process Management: handles creation, scheduling, and termination of processes
Memory Management: manages physical and virtual memory
File System Management: manages files on different storage devices
Device Management: manages device communication via their respective drivers
Security and Access Control: ensures unauthorized users do not access the system and protects against malware and other security threats
User Interface: provides two main types of user interfaces:
- Graphical User Interface (GUI)
- Command-Line Interface (CLI)

Types of Operating Systems

Multitasking/Time-sharing OS: executes multiple jobs by switching between them
Real-time OS: responds to input immediately
Distributed OS: manages a group of independent computers and makes them appear to be a single computer
Embedded OS: used in embedded computer systems like washing machines, ATMs, etc.

Examples of Operating Systems

Desktop OSs: Windows, macOS, Linux distributions (like Ubuntu, Fedora), UNIX
Mobile OSs: Android, iOS, Windows Phone, BlackBerry OS
Server OSs: Windows Server, Linux distributions optimized for server use, UNIX
Embedded Systems: Real-time operating systems like RTLinux, VxWorks, and Windows IoT

Components of an OS

Kernel: core component of an OS, manages operations of the computer and hardware
Shell: interface between user and kernel, receives commands from users and executes kernel's functions

Utility Software

Focuses on supporting the computer infrastructure
Interacts primarily with the computer hardware or the operating system
Importance of Utility Software:
Optimized Performance: ensures that the computer runs at its optimum speed and performance
Enhanced Security: protects computers from threats that could compromise data and privacy
Prevention of Data Loss: ensures that data isn't lost in case of hardware failure or accidental deletions
Better organization: helps to manage files and folders, keep the system organized, and find what you need quickly and easily

Common Types of Utility Software

System Utilities: provide tools to manage and maintain a computer's performance
Virus Scanners & Antimalware Tools: detect and remove malicious software from a computer
Backup & Recovery Utilities: create copies of data and system files
File Compression Utilities: reduce the size of files or folders
Network Utilities: help analyze and monitor networks, diagnose network problems, and measure network performance
