ICT TUTORIAL

Father of computing Charles Babbage was considered the father of computing after his concept and invention of the Analytical Engine in 1837. The Analytical Engine contained an ALU (arithmetic logic unit), basic flow control, and integrated memory, hailed as the first general-purpose computer concept. Unfortunately, because of funding issues, this computer was not built while Charles Babbage was alive. However, in 1910, Henry Babbage, Charles Babbage's youngest son, completed a portion of the machine that could perform basic calculations. In 1991, the London Science Museum completed a working version of the Analytical Engine No. 2. This version incorporated Babbage's refinements, which he developed while creating the Analytical Engine. Although Babbage never completed his invention in his lifetime, his radical ideas and concepts of the computer make him the father of computing. Father of the computer Several people can be considered the father of the computer, including Ala...

My name is Thishanth but my mother calls me “This”. I turned 14 years old this November and I study in class 9th. I studied in Jaffna Hindu College. I have an younger sister named Thishanth. She is like a second mother to me. I have a group of friends at school and out of them Nivenushan is my best friend. He visits my house at weekends and we play outdoor games together. I believe in her and I can share anything with him. I wanted to become a scientist, and being punctual and attentive are my characteristics as I never arrive late for school. Generally, I do my work on my own so that I inculcate the value of being an independent person. I always help other people when they are in difficult situations.

As ICT is becoming more and more part and parcel of teaching, it would be interesting to see how ICT has developed through the last decades. This article aims at helping teachers have a general idea of the history of ICT, from the invention of the first computer up to now. We will also try to peep into the future to see how ICT will look like in the next few decades.  A BRIEF HISTORY OF ICT The telegraph (1837) and telephone (1876) permitted communication by wire over long distances almost instantaneously, a vast improvement over the earlier methods of rail, ship and pony express. Communication by wireless telegraph (1895), shortwave radio (1926) and then more reliable high-frequency microwave radio (1946) overcame the physical constraint of connecting every point by wire or cable. Microwave provided larger-capacity communication channels for transmitting television signals and set the stage for the development of satellites and space communication (1957). In the...

Information and Communications Technology (ICT) is the use of computing and telecommunication technologies, systems and tools to facilitate the way information is created, collected, processed, transmitted and stored. It includes computing technologies like servers, laptop computers and software applications, as well as the wired and wireless communication technologies that support telephones, the Internet, the Internet of Things (IoT) and the metaverse. The goal of ICT is to improve access to information and and make human-to-human, human-to-machine and machine-to-machine (M2M) communication easier and more efficient.
