Nulls

As a noun, 'nulls' refers to instances where a value or item is rendered absent, void, or lacking significance. These absences can exist in data fields (e.g., a blank cell in a spreadsheet), legal documents (e.g., a clause deemed invalid), or systems of measurement (e.g., a zero reading). It represents the state of nothingness, an empty set, or a lack of meaningful content. The concept extends beyond literal zeros to encompass the erasure or invalidation of data or information, and may be the result of computational or data processing errors. It often contrasts with existing, meaningful, or valid data.
