Telepresence technology goes beyond traditional video conferencing by creating a more immersive and lifelike experience. While video conferencing allows participants to see and hear each other, telepresence aims to make participants feel as if they are physically present in the same room. This is achieved through advanced audiovisual equipment, high-definition displays, and often 3D visualization, creating a more natural and engaging interaction.

Cloud computing, also known as tele-computing, involves accessing and using computing resources (such as storage, processing power, and software applications) over the internet, rather than relying solely on local infrastructure. Its advantages include scalability, allowing users to easily adjust resources based on demand; cost savings through pay-as-you-go models; accessibility from anywhere with an internet connection; and reduced need for local hardware maintenance.

Various industries have benefited from ICT applications and communication systems. For example, healthcare has seen advancements in telemedicine, enabling remote consultations and diagnostics. Education has been transformed by online learning platforms. Businesses use teleconferencing and telepresence for remote collaboration, and industries like logistics utilize GPS for accurate tracking and routing.

Data processing systems play a crucial role in modern information management by collecting, storing, processing, and outputting data in various formats. They help organizations manage and analyze large volumes of data, facilitating decision-making and generating insights. Examples include databases, spreadsheets, and enterprise resource planning (ERP) systems, which automate and streamline business processes.

The Global Positioning System (GPS) is a satellite-based navigation system. It consists of a network of satellites that orbit Earth, transmitting signals to GPS receivers on the ground. By calculating the time it takes for signals to travel from multiple satellites to the receiver, the receiver can determine its precise location on Earth's surface. GPS is used for navigation, mapping, surveying, location-based services (such as ride-sharing apps), outdoor activities, and military applications.
