Systems that collect data need a one to one mapping between data entered and its meaning.
Truthfully, this is most common for data NOT entered. I’ve seen a lot of systems where a field which is not relevant is left blank. How do you know which ones were left blank intentionally and which ones were accidental?
If you’re going to bother collecting data why not be as specific as possible? Use units. Number of CPUs? Did you mean sockets or cores? Amount of RAM? Disk size? Is that in MB, GB, or TB?
“N/A” is a perfectly acceptable answer, too, if everybody knows what it means.
