Information Technology Overview

Introduction to Information Technology

  • Humans rely heavily on inanimate objects (e.g., vehicles, communication devices) for ease and efficiency.
  • Information technology (IT) encompasses the use of computer systems, storage, networks, and devices to manage electronic data.

Definition of Information Technology

  • IT is the use of technology to create, modify, transfer, store, and exchange electronic data.

Understanding Data

  • Data includes facts, statistics, numerical sequences, and patterns.
  • Data is analyzed, stored, and used as a component for users to obtain necessary information.

Value of Information Technology

  • IT processes data more reliably and efficiently than manual methods (brain, paper, and pen).
  • Computers can process massive amounts of data simultaneously and secure information effectively.

Applications of Information Technology

  • IT is vital in business operations including:
    • Customer service and communication
    • Financial record-keeping
    • Everyday handling of electronic data
  • Essential for business scalability and profitability.

Hardware vs. Software

  • Hardware: Tangible technology (e.g., PCs, laptops, mobile devices).
  • Software: Intangible technology (e.g., websites, applications).
    • Software Types:
      • System Software: Basic programs for computer functions (e.g., operating systems like iOS, Android).
      • Application Software: Specific programs for tasks (e.g., databases, email servers, collaboration tools like Slack, Dropbox, Google Drive, Microsoft Office).

Career Path in Information Technology

  • IT offers a wide range of career opportunities with strong job security.
  • Median annual wage for IT occupations: $97,000, significantly higher than the average wage of $45,000 for other fields.
  • Entry-level IT positions (e.g., Help Desk Technician) can start at over $50,000 annually.
