Study Notes

Software Programs

  • Software functions only when loaded into RAM and saved permanently on the hard disk
  • Programming languages create commands to perform specific tasks
  • Software commands can be accessed through menus, toolbars, shortcuts, etc.
  • Algorithms are sets of rules that guide data input and output formats (text, numbers, sound, etc.)

Operating Systems

  • Operating systems are collections of programs controlling a computer's interactions and communicating with the user
  • They perform essential functions like managing input/output devices, files, and file types
  • Every computer requires an operating system to function
  • Popular operating systems include DOS, Windows, Unix, Linux, and Apple Operating System (macOS).

Windows Operating System

  • Windows allows "what you see is what you get" (WYSIWYG) screen displays
  • Each version improves graphics and file management
  • Windows 8 had advanced graphics and enhanced file/disk management
  • Windows 10 is a continually updated operating system

Macintosh Operating System

  • Designed for Apple Macintosh computers
  • Provides a graphical user interface (GUI)
  • Was one of the original GUI systems and set a standard for WYSIWYG programs

UNIX

  • Created in the early 1970s by programmers for programmers
  • Designed for flexibility, using one of the more common programming languages
  • Primarily uses one-line commands, not a graphical user interface, and is popular with universities and researchers

Linux

  • Based on Unix, offering more of a graphical user interface
  • Readily available and popular for high-end servers and entrepreneurial software developers

Handheld Operating Systems

  • Designed for personal digital assistants (PDAs)
  • Operating system type depends on the PDA type (e.g., Palm OS, Windows CE)
