• Five Major Components of an Information System:

  1. Hardware: The physical components of a computer system, such as the CPU, RAM, hard drive, monitor, keyboard, and mouse.
  2. Software: Programs and applications that instruct the hardware to perform specific tasks. Examples include operating systems (like Windows), word processors, and database management systems.
  3. Data: Raw facts and figures that are processed into meaningful information. This includes both structured data (like numbers and dates) and unstructured data (like text and images).
  4. People: The individuals who interact with and utilize the information system, including users, system administrators, programmers, and support staff.
  5. Processes: The organized procedures and rules that govern the use and operation of the information system, including data entry, data processing, and information output.

• Three Examples of Information System Hardware:

  • Central Processing Unit (CPU): The “brain” of the computer, responsible for processing instructions and executing commands.
  • Monitor: The display device used to view information on the computer screen.
  • Hard Drive: The primary storage device for data, where files and programs are stored.

• Microsoft Windows:

  • Software: Microsoft Windows is an operating system, a type of software that manages all the hardware and software resources on a computer. It provides a platform for other applications to run.

• Application Software:

  • Software designed to perform specific tasks for users. Examples include:
    • Word processors: Microsoft Word, Google Docs
    • Spreadsheets: Microsoft Excel, Google Sheets
    • Browsers: Chrome, Firefox, Safari
    • Database management systems: MySQL, Oracle
    • Games: Fortnite, Minecraft

• Roles of People in Information Systems:

  • Users: Individuals who interact with and use the information system to perform their work tasks.
  • System Administrators: Responsible for managing and maintaining the computer systems and networks.
  • Programmers: Develop and maintain software applications.
  • Database Administrators: Manage and maintain databases.
  • System Analysts: Analyze business requirements and design information systems to meet those needs.
  • End Users: Individuals who utilize the information system to perform their job functions.

Key takeaway: Information systems are complex entities that involve a combination of hardware, software, data, people, and processes working together to achieve specific goals.
