Study Notes

Software

Software is a collection of programs, data, and instructions that tell a computer how to perform specific tasks.
It's intangible, unlike hardware, which are the physical components of a computer system.
Software manages, controls, and coordinates hardware components, enabling user interaction and function execution.

Main Categories of Software

System Software

System software manages and controls computer hardware, allowing other software and users to operate correctly.
It acts as a platform for application software.
Examples include Operating Systems (OS), Device Drivers, and Utilities.
- Operating Systems (OS): Control basic functions like file management, memory management, and device management. Examples are Windows, macOS, Linux, and Android.
- Device Drivers: Software that lets the OS talk to hardware (printers, network cards, graphics cards).
- Utilities: Programs for maintenance tasks, like disk cleanup and antivirus protection.

Application Software

Application software is used by users to perform specific tasks like creating documents, analyzing data, or editing photos.
Examples include Productivity Software, Multimedia Software, Web Browsers, and Games.
- Productivity Software: Word processors, spreadsheets, and presentation software (e.g., Microsoft Word, Excel, PowerPoint).
- Multimedia Software: Programs for creating and editing graphics, videos, and music (e.g., Adobe Photoshop, Final Cut Pro).
- Web Browsers: Software for accessing and interacting with websites (e.g., Chrome, Firefox, Safari).
- Games: Software for entertainment, including computer and mobile games.

Operating System (OS)

An OS is a vital system software that manages hardware and software resources, acting as a bridge between users and hardware.
It ensures smooth interaction and efficient operation among different applications and users.
Without an OS, a computer wouldn't function properly.
OS manages all software and hardware, coordinating CPU, memory, and storage access among active programs.

Popular Operating Systems

Microsoft Windows: A widely used OS for personal computers, known for its user-friendly GUI and broad software support.
macOS: Apple's OS for Macintosh computers, known for its sleek design, security, and seamless integration with other Apple products.
Linux: An open-source OS known for its flexibility, security, and popularity among developers. Linux distributions include Ubuntu, Fedora, and Debian.
UNIX: A foundational multitasking OS that influenced other operating systems and is common in servers and workstations.
Android: A mobile OS based on Linux, widely used in smartphones and tablets.
iOS: Apple's mobile OS for iPhones and iPads, known for its smooth performance, security features, and curated app ecosystem.

Mobile Devices and OS

Mobile devices (phones and tablets) use operating systems specifically designed for their functionalities, unlike desktop computers.
These OSs are generally less complex than desktop counterparts, but still enable various functions like watching movies, browsing the web, managing calendars, and playing games.

File Formats

File format dictates the structure of a file, guiding programs on how to display its content.
A program needs to understand a file's format to open it.
Some formats follow standards (like HTML5 for webpages).
Others are proprietary.
- Open Formats: Publicly available standards, free-to-use like HTML, PDF.
- Proprietary Formats: Defined by a company, and use is restricted, or requires payment for access like MP3.

File extensions

File extensions are used by operating systems to determine a file's format.
For example, a file with the .docx extension (e.g., a Word document) is opened by default using Microsoft Word. This is an example of proprietary software.

Types of Software (Proprietary & Open Source)

Proprietary Software

Owned, developed, and controlled by a company or individual.
Source code is typically not publicly available, and users usually need to buy a license.
Ownership is retained by the developer/company.
Licensing restricts use, modification, redistribution, and accessing the source code.
Companies often provide support, bug fixes, and updates.
Examples: Windows (OS), Microsoft Office (software suite), Adobe Photoshop (image editing software).

Open-Source Software

Source code is freely available for anyone to use, view, modify, and share.
It's collaboratively developed in communities.
Ownership is often community-based, not solely owned by a company or person.
Software is typically distributed under licenses, permitting modification and redistribution (e.g., GNU General Public License (GPL)).
Support is often community-based, but some companies do provide paid support.
Examples: Linux (OS), Apache HTTP Server (web server), GIMP (image editing software), LibreOffice (office suite).

User Interfaces (UI)

UI is the space where human-computer interactions occur.
Its goal is to allow effective and efficient user interaction.
UI takes various forms.
- Graphical User Interface (GUI): Users interact via graphical elements (windows, icons, menus, buttons). It is visually appealing and intuitive, though it can consume more resources.
- Command-Line Interface (CLI): Users interact through text commands, often used by developers or administrators. It is powerful, but requires memorizing commands, and is less user friendly for beginners.
