Lesson Content/Board Summary

Information Technology Revision

1. Definition of Information Technology (IT)

Information Technology (IT) refers to the use of computers, storage, networking, and other physical devices, infrastructure, and processes to create, process, store, secure, and exchange all forms of electronic data. It involves the application of technology to handle information.

2. Components of a Computer System

A computer system is made up of two main components:

  • Hardware: These are the physical and tangible parts of a computer system that can be seen and touched.
    • Examples: Monitor, Keyboard, Mouse, Central Processing Unit (CPU), Printer, Scanner, Speakers, Hard Disk Drive.
  • Software: These are the set of instructions or programs that tell the hardware what to do. They are intangible.
    • Examples: Operating Systems (e.g., Windows, Linux), Application Software (e.g., Microsoft Word, Google Chrome, Paint), Utility Software (e.g., Antivirus).

3. Types of Computer Networks

A computer network is a group of two or more interconnected computer systems that share resources and data. Common types include:

  • Local Area Network (LAN): Connects computers within a limited geographical area, such as a home, school, or office building.
  • Wide Area Network (WAN): Connects computers over a broad area, such as cities, countries, or even globally. The Internet is the most well-known example of a WAN.

4. Internet and its Uses

The Internet is a global system of interconnected computer networks that uses standard communication protocols to serve billions of users worldwide.

The following are common uses of the Internet:

  • Information retrieval (research, news)
  • Communication (email, social media, video calls)
  • Online learning (e-learning, tutorials)
  • Entertainment (streaming, gaming)
  • Online shopping and banking
  • Business and marketing

5. Computer Security

Computer security refers to the protection of computer systems and data from theft, damage, unauthorized access, or disruption.

Common Computer Security Threats:

  • Viruses and Malware
  • Hacking
  • Phishing (fraudulent attempts to obtain sensitive information)
  • Data theft

Safeguards for Computer Security:

  • Using strong passwords
  • Installing antivirus software
  • Regularly updating software
  • Being careful about clicking suspicious links or opening unknown attachments
  • Backing up important data

Teaching Methods/Instructional Techniques
