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.
Popular Operating Systems
- 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.
