Information refers to organized data that provides meaning or context. In the digital realm, information can be structured, manipulated, and analyzed to extract valuable insights and support decision-making processes. For example, data analytics and artificial intelligence (AI) technologies enable organizations to derive actionable intelligence from large datasets, driving innovation and efficiency.


Communication in the context of ICT involves the transmission and exchange of information using different mediums and technologies. Traditional communication methods such as emails, phone calls, and video conferences have evolved with advancements like Voice over Internet Protocol (VoIP), which enables voice communication over the internet, and Unified Communications (UC), integrating various communication channels for seamless interaction.


Technology encompasses hardware, software, and infrastructure components that enable the processing, storage, and dissemination of information. Advancements in technology, such as cloud computing, Internet of Things (IoT), and blockchain, have revolutionized how data is managed, accessed, and secured. Cloud services, for instance, offer scalable and cost-effective solutions for storing and processing data, while IoT devices connect physical objects to the digital world, enabling real-time data monitoring and analysis.

Evolution of ICT

The evolution of ICT can be traced back to the development of computing devices in the mid-20th century. From mainframe computers to personal computers (PCs), the digital revolution has ushered in an era of unprecedented connectivity and innovation. Key milestones in ICT evolution include:
