    Study Notes

    Hardware and Software

    • Hardware refers to the physical components of a computer that are tangible, such as monitors and printers.
    • Common examples of hardware include microphones, mice, and keyboards.
    • Software consists of a collection of instructions that direct hardware functions; examples include Windows Vista and Microsoft Word.

    Types of Computers

    • There are various types of computers including personal computers (PCs), mainframes, laptops, palmtops, and personal digital assistants.

    Input and Output Devices

    • Input devices allow data entry and interaction, examples include keyboards, numeric keypads, pointing devices, and digital cameras.
    • Output devices display or present data processed by the computer, including monitors, printers, and speakers.
    • Specific examples of input devices:
      • Joysticks, touch screens, and scanners.

    Operating Systems

    • Two primary types of operating systems are Command Line Interface (CLI) and Graphical User Interface (GUI).

    Monitors

    • CRT (Cathode Ray Tube) monitors are known for excellent color accuracy and brightness but are heavy and consume a lot of energy.
    • LCD (Liquid Crystal Display) monitors are lighter, save space, and produce less glare but have poorer color accuracy and can be expensive.

    Projectors

    • Multimedia projectors enhance the user experience with large viewing areas but may suffer from lower image quality and require cooling fans.

    Systems Analysis and Design

    • Key stages of systems analysis and design include:
      • Research: Collecting information about the current system.
      • Analysis: Understanding and identifying issues with the existing system.
      • Design: Developing a new system to address current problems.
      • Production: Creating the new system based on the design.
      • Testing: Ensuring the new system functions as intended.
      • Documentation: Creating guides for using and understanding the new system.
      • Implementation: Transitioning to the new system.
      • Evaluation: Ensuring the new system meets established expectations.

    Data Collection Methods

    • Methods for collecting system information include observation, interviews, questionnaires, and document collection.
    • Advantages and disadvantages of these methods vary; for instance:
      • Observation can yield unbiased information but may disrupt normal work.
      • Questionnaires are quick and simple but limit information to predefined questions.
      • Interviews can provide detailed insights, but they may be time-consuming.
