data logging

Data logging is like keeping a notebook. Instead of writing down information with your hand on paper, it's like a digital version of taking notes. Data logging is used when computers or machines collect information and store it to be used later. The collected data is usually stored in a file, which is like a digital scrapbook. The information stored in this digital scrapbook can be used to learn more about how things work, or to track changes over a period of time.
