Introduction to ICT

Information and Communication Technology (ICT) integrates computing and communication tools. It enables the processing, storage, and transmission of data globally. Modern examples include smartphones, the internet, and cloud services like Microsoft 365.

Digital communication landscape: ICT, devices, and global data transmission.

Digital Age Foundation

Information and Communication Technology (ICT) forms the bedrock of modern society, acting as the essential infrastructure for nearly every sector. From enabling global financial transactions to facilitating remote healthcare diagnostics and smart city management, ICT drives unprecedented innovation. This pervasive integration necessitates the development of critical 21st-century skills like digital literacy, computational thinking, and collaborative problem-solving across all disciplines.

Connected infrastructure: ICT enables global interactions and innovation.

Information Technology (IT)

Communication Technology (CT)

Information Technology encompasses the creation, processing, storage, retrieval, and management of digital data and information. This involves hardware, software, and services used to handle vast datasets, such as large-scale database systems like Oracle or cloud platforms like Amazon Web Services (AWS). IT fundamentally underpins organizational efficiency by transforming raw data into actionable insights for strategic decision-making.

Communication Technology focuses on the transmission of information across various distances, facilitating interaction between individuals, devices, and systems. It includes infrastructure like fiber optic cables and advanced wireless networks (e.g., 5G), alongside protocols that enable seamless data exchange. Platforms such as Voice over IP (VoIP) services like Zoom and satellite communications exemplify CT's critical role in global real-time connectivity.

Core Component: Hardware

• Physical, tangible parts of an ICT system.

• Input devices: Keyboard, mouse, scanner, webcam.

• Output devices: Monitor, printer, speakers, projector.

• Processing (CPU, GPU), Storage (SSD, RAM).

Core Component: Software &amp; Data

Software consists of programmed instructions that direct hardware to execute specific tasks, such as operating systems like Linux or applications like Adobe Photoshop. Data, conversely, refers to the raw, unprocessed facts and figures, like sensor readings from an IoT device or user input into a database. These two elements are fundamental for any ICT system's functionality and information processing.

Combinatorial data representation: graphs, tables, and probability.

Core Component: Networks &amp; People

Information and Communication Technology (ICT) fundamentally relies on intricate networks, such as the global Internet or enterprise LANs, which facilitate the seamless exchange of vast data volumes. Simultaneously, people are indispensable within this ecosystem, acting as end-users consuming services, developers crafting innovative applications like mobile apps or AI models, and administrators maintaining critical infrastructure. This symbiotic relationship underscores how human interaction and technical architecture converge to drive digital progress.

Technology aids learning about society, ideology, and culture.

Input Devices Explained

• Keyboards, mice translate user input to digital signals.

• Scanners digitize physical documents, images for processing.

• Microphones convert analog sound waves into digital audio.

• Specialized input: touchscreens, biometric sensors, joysticks.

Output Devices Explained

Output devices translate processed digital data from a computer into human-perceptible forms. For instance, a monitor renders digital signals into visual displays, while a laser printer produces tangible hard copies of documents. Similarly, speakers convert digital audio files into sound waves, allowing us to hear music or voice recordings.

Televisions display audiovisual content, showcasing technological advancements.
