electronic data processing
Electronic data processing ( EDP ) refers to the electronic recording, processing, transport, output and reproduction of data. It takes place through the execution of processes described by software on hardware systems . The description of the processes can also be part of the hardware (see also firmware ).
In detail, IT includes:
- Data acquisition, in which physical values or events through which information is transported ( message ) are encoded into data. This is done using sensors such as keyboards, measuring systems, cameras, etc.
- The actual electronic processing of this data. It is carried out by processors by interpreting software produced for the desired processing. See algorithm .
- The output of the data on displays or media, which enables their interpretation by humans as a message, or on physical actuators . The transmission of data to a mass storage device or a connected data processing system is also part of the output.
