1.0 INFORMATION AND COMUNICATION TECHNOLOGY AND SOCIETY
* The technology required for information processing.
* The use of electronic computers, communication devices and software applications to convert, store, protect, process, transmit and retrieve information from anywhere, anytime.
Describe the brief evolution of computers.
* First Generation (1940-1956) ENIAC (Electronic Numerical Integrator and Computer) build by Presper Eckert and Willian Mauchly that use vacuum tube instead of MARK 1 that use mechanical switches. * Second Generation (1956-1963) Transistor was created and used to transfer electronic signals across a resister. Famous computer scientists: John Bardeen, Walter Houser, William Shockley. * Third Generation (1964-1971) IBM 370 series was introduced in 1964. Other computer models introduced were CDC 7600 and B2500. Integrated circuit(IC) had been developing which reduced the size and cost of computers. * Fourth Generation (1971-Present) in 1971, Intel created the first microprocessor. In 1971, Steve Jobs built the first apple computer. In 1981, IBM introduced the first personal computer. Hardware technology such as silicone chips, microprocessor and storage devices were invented.
* Fifth Generation (Present and Beyond) technologically advance and are still being development to become more efficient. Examples of new hardware technology: Robotics, virtual reality, intelligent systems, program which translate languages. * New Era Computer is when the technology of computer has become more advanced, modern and sophisticated. Examples of the latest invention: Super Computers, Mainframe Computers, Mini Computers, Personal Computers, Mobile Computers.
List the main sector that used ICT in everyday life.
