ICT stands for information and communication technology. In general, it is a combination of information technology, a focus on computers and related devices, and digital telecommunications, including mobile phones, the internet, and other digital networks. The term may be a bit amorphic, but it’s fair to say that types of ICT include mobile phones, the internet, and home and office networking devices.
Types of information and communication technologies
Forms of ICT have expanded in recent decades. Digital mobile phones, including smartphones and traditional popular phones, have become popular in many countries. Internet routers and modems are found in offices and homes around the world. Communication software from social networking tools to encrypted messaging apps has exploded in popularity.
As digital networks have moved from being relatively slow and expensive, computers and phones becoming more reliable and easier to use, they have moved from the realm of hobbyists and early technology users to everyday devices.
The development of mobile phone technology
In recent years, billions of people around the world have started using mobile phones. In some cases, digital devices are even cheaper and more reliable than their wired devices, and newer devices are equipped with fast internet access and multiple applications downloads.
While mobile phones were initially used expensive, bulky to carry around and often lost signal, modern mobile phones are reliable and easy to transport. Society has also adapted to the point where it is difficult for many people to sustain their business and social lives without carrying a mobile phone.
At the same time, mobile plans become simpler, especially when providing basic communication services such as calling, texting, and voicemail. Many users no longer have to worry about exceeding their allowed minutes or waiting all night and weekend to make calls.
The rise of the Internet.
The Internet has gone from a limited government and academic experiment of the 1960s to an almost universal part of modern life. Modems, which stands for modulator-demodulator, are used to convert digital signals from computers to other forms that can be transmitted over a phone, cable or another network.
Examples of internet-related communication technologies include dial-up modems of the 1990s and more modern wireless routers and cable internet modems now found in many homes and businesses. Modern mobile phones and many computers can connect to built-in WiFi modems or cellular modems that allow them to connect to the phone service provider’s network. Wi-Fi routers allow them to connect to a modem installed locally, usually a hard-wired modem and connect to a larger network.
Many offices, universities, and other environments also have internal networks, known as intranets, which are used for secure internal communications.
