checksumming

This term is a technical gerund used primarily in computer science and data transmission. It describes the active process of generating or verifying a checksum to detect errors in raw data. While it functions as a verb in progress, it is frequently used as a noun to describe the general mechanism of integrity verification.

Because it is derived from the noun "checksum," the word carries a highly specific technical register. It is rarely used outside of software engineering, networking, and cybersecurity contexts. In these fields, it implies a rigorous, algorithmic check rather than a casual inspection.
