Study Notes
Computer Software
- Software is one of the main components of computer systems
- Software is a collection of programs and related data
- Software provides instructions to the computer on what to do and how to accomplish each task
Types of Software
- There are three main types of software:
- Programming software
- System software
- Application software
Programming Software
- Programming software helps programmers develop other software
- Programming languages are used in programming software
- Examples of programming languages: C, C++, C#, BASIC, JAVA, Visual Basic, Python, etc.
- Programming software includes tools like compilers, assemblers, debuggers, interpreters, and linkers
Levels of Programming Languages
- Programming languages are categorized hierarchically
- Languages are ranked based on proximity to the computer's language (low level) or the human language (high level)
- Examples of high-level languages: Python, JAVA, C++
- Examples of low-level languages: Assembly, Machine language
System Software
- System software operates computer hardware and provides basic functionality
- System software enables the running of application programs
- System software includes the operating system and utility programs that manage computer resources at a low level
Operating Systems (OS)
-
OS functions:
- Manages computer tasks and resources
- Provides an interface between the user and the computer hardware/software applications
- Controls hardware and software applications
- Supports built-in utility programs to fix errors
- Manages data access (hard drive and RAM)
- Manages network communication
-
Types of OS:
- Multi-tasking: Runs multiple programs at once
- Single-tasking: Runs one program at a time
- Multi-user: Allows multiple users to access the system concurrently
- Single-user: Usable by a single user at a time
-
Examples of operating systems: Windows, Linux, iOS, Android, macOS
-
System software also includes system utilities (disk defragmenter and System Restore)
Applications
- Applications perform tasks at home, school, and business
- Examples of application software:
- Word processing (Microsoft Word, LibreOffice Writer)
- Spreadsheets (Microsoft Excel, LibreOffice Calc)
- Presentations (Microsoft PowerPoint, LibreOffice Impress)
- Databases (Microsoft Access)
- Note-taking (Microsoft OneNote)
- PIM/Email (Microsoft Outlook)
- Business apps (accounting software, CAD)
- Multimedia applications (creating and editing videos and audio)
- Educational applications (Blackboard, Moodle, Canvas)
Software Licenses
- Software licenses are legal agreements governing software usage and distribution
- Types of software licenses:
- Register ware: Requires user registration
- Shareware/Demoware: Free trial periods
- Freeware: No cost or optional payment
- Open Source Software (OSS): Source code is available for inspection, modification, and enhancement
- Abandon ware: No longer in use
