| Communication | The exchange of information between people or systems using a medium (e.g., voice, text, video, sensors). |
| Technology | Tools, devices, and infrastructure that enable the capture, storage, processing, and transmission of information. |
| ICT | The integrated use of computers, telecommunications, and other digital resources to create, store, retrieve, transmit, and manipulate information. |
Key Idea: ICT is not just “computers”; it includes networks, software, mobile devices, the internet, and emerging platforms such as IoT (Internet of Things) and cloud services.
| Component | Typical Examples | Primary Functions |
|---|---|---|
| Hardware | PCs, laptops, tablets, smartphones, servers, routers, switches, sensors | Physical devices that process or transmit data. |
| Software | Operating systems (Windows, Android), applications (Word, Excel), databases, web browsers | Instructions that tell hardware what to do. |
| Networks | LAN, WAN, Wi‑Fi, cellular (4G/5G), satellite links | Connect devices and enable data exchange. |
| Data & Content | Text documents, spreadsheets, multimedia files, web pages, big‑data sets | The actual information being handled. |
| People | End‑users, IT professionals, content creators, decision‑makers | Design, manage, and use ICT systems. |
| Procedures & Policies | IT security policies, data‑privacy regulations (GDPR), backup plans | Rules and processes that govern ICT use. |
