Information and Communication Technology is all technologies related to broadcast media, telecommunications, intelligent building management systems, network-based control and monitoring functions, audiovisual processing and transmission systems. ICT Application DetailsMeasurement applicationsMeasurement application worked as the computer can then either monitor the sensor's signal and react to changes or it can record the sensor's data at predetermined time intervals. The combination of information and communication technology (ICT) and sensor technology has a lot of promise for monitoring, transmitting,It is also used in managing field water quality data and, as a result, for establishing effective water quality management. Control applicationsIn a boiler, a gas supply is used to heat water. A microprocessor controls a valve on the gas supply that opens if the heating levels need to be increased. When the temperature dips below a certain level, a water pump is utilised to circulate hot water throughout the central heating system. Modelling applicationsA crash simulation is a computer simulation that simulates a damaging crash test of a car. Using modelling applications, virtual accident studies can assist reduce the number of full-scale automotive tests. The results of these tests can be utilised to anticipate real-world car behaviour, occupant interactions, and deformation during a collision. Expert systemsAn expert system is a computer programme that simulates the abilities of a human expert to make decisions. The goal of a medical expert system is to help doctors with their diagnoses. This means that a medical expert system recommends a diagnosis based on knowledge of diseases and facts about the patients. Therefore, A-II, B - III, C - I, D - IV is the correct option.
