Communication
ICT standardisation is the voluntary cooperation for the development of technical specifications that outlines the agreed properties for a particular product, service, or procedure.
Technology is the use of scientific knowledge, experience and resources to create processes products that fulfill human needs.
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.
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.
Technology
Standards are critical to the interoperability of ICTs and whether we exchange voice, video or data messages, standards enable global communications by ensuring that countries’ ICT networks and devices are speaking the same language.
