Study Notes

User Interfaces Overview

  • A user interface (UI) facilitates interaction between users and computer systems.
  • Types of user interfaces are categorized into software and hardware interfaces.

Software User Interfaces

  • Graphical User Interface (GUI)

    • Comprises interactive visual components like icons, cursors, and buttons.
    • Enhanced by sounds and visual effects (e.g., transparency, drop shadows).
    • Considered more user-friendly compared to command-line interfaces.
    • Examples include operating systems and applications like Windows, Linux, iOS, Word, Excel, and Access.

  • Command Line Interface (CLI)

    • Operates via text input to execute operating system functions.
    • Was the primary method of interaction in early computing but is less common today.
    • Still utilized by developers and system/network administrators for tasks not available in GUIs.
    • MS-DOS serves as a classic example of a CLI.

  • Menu-driven Interface

    • Displays available commands through menus; users select options to perform actions.
    • Simplifies usage by eliminating the need to memorize command sets.
    • Can become cumbersome if menu levels are extensive, hindering user navigation.
    • Commonly found in ATMs for managing account functions like withdrawals and deposits.

Hardware User Interfaces

  • Touch User Interface
    • Operates through screen touch detection, translating gestures (tapping, swiping, pinching) into commands.
    • Intuitive and accessible to users of all ages, promoting ease of interaction.
