Definition

• Information Technology (IT) refers to the use of computers, networking, and other electronics to store, retrieve, transmit, and manipulate data.

Key Components

1. Hardware

   • Physical devices (e.g., computers, servers, routers).
   • Components like CPU, RAM, storage devices.

2. Software

   • Programs and applications (e.g., operating systems, productivity software).
   • Two categories: system software (manages hardware) and application software (performs tasks).

3. Networks

   • Interconnected systems that share resources and data.
   • Types: Local Area Network (LAN), Wide Area Network (WAN), and the Internet.

4. Data

   • Information processed or stored by a computer.
   • Types: structured (databases) and unstructured (emails, videos).

IT Functions

• Data Management: Storing and organizing data.
• System Administration: Managing and maintaining IT systems.
• Network Management: Ensuring the integrity and efficiency of networks.

Current Trends

1. Cloud Computing

   • Using remote servers hosted on the internet for data storage and processing.
   • Offers scalability, cost-effectiveness, and flexibility.

2. Artificial Intelligence (AI)

   • Technologies that enable machines to mimic human intelligence.
   • Applications include data analysis, automation, and customer service.

3. Cybersecurity

   • Protecting computer systems from theft, damage, or unauthorized access.
   • Emphasizes the importance of firewalls, encryption, and security protocols.

4. Big Data

   • Large, complex datasets analyzed for insights and trends.
   • Drives business decisions and innovations.
