Which factor has the most significant impact on the amount of space needed to archive digitized data?

The factor that has the most significant impact on the amount of space needed to archive digitized data is the sampling rate. The sampling rate refers to how frequently the data is sampled per unit of time during the digitization process. A higher sampling rate means more samples are taken, resulting in a more detailed representation of the original signal but also requiring more storage space.

For example, in audio data, if the sampling rate is increased from 44.1 kHz to 96 kHz, the resulting file size increases because more data points are collected over the same duration. This directly increases the volume of data that must be stored, making the sampling rate a crucial factor in determining storage requirements.

Other factors, while important, typically impact storage space to a lesser extent. The compression method can reduce the file size significantly depending on how effectively the data can be compressed, but it does not fundamentally change the initial amount of data generated by the sampling process. The data type is relevant because different types (like audio, video, or image files) have varying inherent space requirements, but again the sampling rate is a primary determinant. Lastly, the storage medium (like HDD or SSD) influences access speed and cost but does not change the data size itself. Thus,
