Week 1:Introduction to information technology

Information and communications technology (ICT) is an extended-term for information technology (IT) which stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals), computers as well as the necessary software, its storage, and the audio-visual systems, which enable all users to access, store, transmit, and manipulate information. The term ICT is also used to refer to the combining of audio-visual and telephone networks with computer networks through a single cabling or link system. There are large economic incentives (huge cost savings due to elimination of the telephone network) to merge the telephone network with the computer network system using a single unified system of cabling, signal distribution, and management.
