electronic data processing

from Wikipedia, the free encyclopedia

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:

  1. 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.
  2. The actual electronic processing of this data. It is carried out by processors by interpreting software produced for the desired processing. See algorithm .
  3. 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.

Electronic data processing takes place through electronic data processing systems, which today not only include computers , but also controls, clocks , cell phones and electronic consumer products.
