    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
