Study Notes

Computer Software

  • Computer software is a collection of programs, data, and instructions that tell a computer how to perform specific tasks.
  • It's intangible, existing as digital assets unlike the physical components of a computer system (hardware).
  • Software manages, controls, and coordinates the hardware, enabling user interaction and diverse functions.

Main Categories of Software

System Software

  • Manages and controls computer hardware, enabling proper operation of other software and users.
  • It serves as a platform for application software.
  • Includes:
    • Operating Systems (OS): Control basic functions, file management, memory management and device management (e.g., Windows, macOS, Linux, Android).
    • Device Drivers: Allow the OS to communicate with hardware devices (e.g., printers, network cards, graphics cards).
    • Utilities: Perform maintenance tasks like disk cleanup, and antivirus protection.

Application Software

  • Used by users to perform specific tasks (creating documents, analyzing data, editing photos).
  • Examples:
    • Productivity: Word processors, spreadsheets, presentation software (e.g., Microsoft Word, Excel, PowerPoint).
    • Multimedia: Graphics, video, and music editing programs (e.g., Adobe Photoshop, Final Cut Pro).
    • Web Browsers: Access and interact with websites (e.g., Chrome, Firefox, Safari).
    • Games: Provide entertainment (computer and mobile games).

Operating System (OS)

  • A vital system software that manages computer hardware and software resources.
  • Acts as an intermediary between users and hardware.
  • Ensures efficient and secure interaction between applications and users.
  • Manages all of the software and hardware resources on the computer.
  • Simultaneously runs multiple programs.
  • Coordinates all program access to the CPU, memory, and storage.
  • Microsoft Windows: Widely-used OS for personal computers – known for GUI, ease of use, and broad software support.
  • macOS: Apple's OS for Macintosh computers – sleek design, security, seamless integration with Apple products.
  • Linux: Open-source OS – known for flexibility, security, and popularity among developers. Distributions include Ubuntu, Fedora, and Debian.
  • UNIX: Multiuser, multitasking OS – influenced many other operating systems, including Linux. Commonly used in servers and workstations.

Operating Systems for Mobile Devices

  • Mobile devices (phones, tablets) use different OS than desktop computers.
  • Examples:
    • Android: Linux-based OS – developed by Google; widely used.
    • iOS: Apple's mobile OS – known for smooth performance, security, and curated app ecosystem.
  • These OS are generally less fully featured than desktop counterparts. They can't perform every task, but they play a wide variety of functions.

File Formats

  • File format defines how a program displays file contents
  • Programs may handle files in different ways
  • Some file formats follow standards (e.g., HTML5).
    • Open formats: Published openly, free to use. Examples: HTML, PDF
    • Proprietary formats: Owned by a company – others can use if they pay for license. Examples: MP3.

File Extensions

  • Operating systems use file extensions to identify file formats.
  • E.g., .docx files open with Microsoft Word by default.

Types of Software (Specific Categories)

Proprietary Software

  • Developed, owned, and controlled by a company/individual.
  • Source code not available to the public.
  • Users must purchase a license.
  • Ownership stays with developer; users generally can't modify or redistribute.
  • Licenses limit how the software can be used.
  • Support often provided by company.

Open-Source Software

  • Source code is freely available for viewing, modifying, and distributing.
  • Usually collaboratively developed by communities.
  • Ownership and responsibility distributed among community members.
  • Published under licenses like GNU GPL or MIT License – allowing modifications and sharing.
  • Support typically community-reliant. (Paid support options also exist).

User Interfaces (UI)

  • UI are spaces for interactions between humans and computers/systems.
    • They facilitate effective and efficient user interaction.
  • Diverse forms exist including:

Graphical User Interface (GUI)

  • Uses graphical elements (windows, icons, menus, buttons).
  • Intuitive and user-friendly, even for non-technical users.
  • Typically more visually appealing and interactive.
    • Consumes more system resources than other interfaces.

Command-Line Interface (CLI)

  • Users interact via text commands.
  • Primarily used by developers and system administrators.
  • Relies on fewer resources.
  • More powerful for advanced users.
  • Can be difficult for beginners.
  • Needs to memorize commands.
