Here's a summary of common ICT (Information and Communication Technology) concepts: 1. Hardware: Physical components of a computer system, such as CPU, memory, and storage. 2. Software: Programs and operating systems that run on hardware, including applications and system software. 3. Networking: Connection of devices to share resources, communicate, and exchange data. 4. Database Management: Organizing, storing, and retrieving data in a structured and controlled manner. 5. Security: Protecting computer systems, networks, and data from unauthorized access, use, disclosure, disruption, modification, or destruction. 6. Cloud Computing: On-demand delivery of computing resources, applications, and services over the internet. 7. Artificial Intelligence (AI): Development of intelligent systems that perform tasks that typically require human intelligence, such as learning, problem-solving, and decision-making. 8. Internet of Things (IoT): Network of physical devices, vehicles, buildings, and other items that are embedded with sensors, software, and connectivity. 9. Cybersecurity: Practices, technologies, and processes designed to protect digital information, computer systems, and networks from cyber threats. 10. Data Analytics: Process of examining data sets to draw conclusions and identify patterns, trends, and insights. 11. E-commerce: Buying and selling goods and services online through digital platforms. 12. Telecommunications: Transmission and reception of information over distance through various electronic means, such as phone, internet, and television. These ICT concepts are fundamental to understanding the digital world and its various technologies, applications, and implications.
