Which equipment helps track and save a digital record of computer use?

The correct answer is Digital Video Recorders (DVR) because they are specifically designed to capture and store video data, including footage from various sources like cameras or security feeds. In the context of computer use, a DVR can be utilized to record screen activity or video outputs, effectively creating a digital record of what is happening on a computer.

DVRs have the capability to save this data in a digital format, which can later be reviewed, accessed, or analyzed. This capability makes them particularly useful in monitoring computer usage, providing insights into user behavior, and maintaining a comprehensive log of activities.

Monitors, while essential for displaying information from a computer, do not record or save data. Closed Circuit TV (CCTV) is typically used for surveillance purposes and might record video feeds from cameras, but it is not specifically tailored for tracking computer usage or saving digital records of computer activity. Video cameras on their own also do not inherently provide the recording and saving functionality necessary for documenting computer usage unless paired with a recording device like a DVR.
