Communication
Communication is an act of transmitting messages. It is a process whereby information is exchanged between individuals using symbols, signs or verbal interactions. Communication is important in order to gain knowledge.
Information refers to the knowledge obtained from reading, investigation, study or research. The tools to transmit information are the telephone, television and radio. Information is knowledge and helps us to fulfill our daily tasks.
Technology is the use of scientific knowledge, experience and resources to create processes products that fulfill human needs.
ICT standardisation is the voluntary cooperation for the development of technical specifications that outlines the agreed properties for a particular product, service, or procedure.
