pnum

Pnum is not a term with a universal definition; it appears as an abbreviation or identifier across different domains, often as a compact label rather than a formal concept. Its precise meaning depends on the context.

In data management, pnum is frequently used as a field name representing a part number or product code in inventories, catalogs, and supplier data. In CSV files, a column header named pnum commonly stores numeric or alphanumeric product identifiers.

In computing and networking, pnum may denote a numeric identifier such as a packet number in traces and logs, or a process number in scheduling and process management. It can also stand in for partition number or page number in paging and memory management.

In software development, pnum is commonly used as a short variable name in source code to denote a counter or identifier for a particular entity, often chosen by the programmer for brevity.
