Lesson 1: ICT (Information and Communications Technology)

Information and Communications Technology (ICT)

It refers to all technology that is used to handle telecommunication and access information.

Modern definitions of ICT

It is the convergence of several technologies including internet and wireless medium, but the primary focus is on the access and sharing of information and communications.

WAN

wide-area network

wireless fidelity (Wi-Fi), Bluetooth, third generation (3G), fourth generation (4G), global system for mobile communications (GSM), general packet radio service (GPRS), data services, dial-up services, virtual private networks (VPN)

Mobile devices can communicate through what communication technologies?

wireless fidelity (Wi-Fi)

a type of wireless local area network technology

Bluetooth

uses packet-based transmission over short range radio signals

data services

data networking services for mobile phones

dial-up services

data networking services using modems and telephone lines

virtual private networks (VPN)

secure access to private network

artificial intelligence, robotics, biometrics, quantum cryptography, computer-assisted translation, 3D imaging and holography, and virtual reality

What are the 7 emerging technologies?

Artificial Intelligence (AI)

the branch of computer science focused with making computers work and act like humans

Robotics

The field of computer science and engineering concerned with creating devices that can move and react to sensory input. It is a form of artificial intelligence.

Biometrics

It is the technology used to measure and analyze human body characteristics such as DNA, fingerprints, eye retinas and irises, voice patterns, facial patterns, and hand measurements, mainly for authentication purposes

Quantum cryptography

The science of encoding and decoding information of messages which depends on physics; not mathematics. It is used for information privacy and security.

Computer-assisted translation (CAT)

The use of computers to assist in the translation of one or more natural languages into another or others, and vice versa.

3D imaging and holography

It is a photographic technique that uses light to project objects in a way that appears three-dimensional.

Virtual real

The term used to describe a three-dimensional, computer-generated environment that can be explored and interacted with by a person.
