What does scanning mean?
Scanning is the process of looking over or through something in order to find information, assess it, or record it with a device. As a verb, scanning is often a quick, systematic action: a person scans a list, a security worker scans a boarding pass, or a system scans a barcode. In electronic use, scanning means capturing an image or data in a form that computers can process. The noun scanning names that activity or process, and scanning also has the literary sense of examining verse for metre and rhythm. The word is neutral in most contexts, though it can suggest careful, methodical inspection rather than relaxed reading. It is also useful in medicine and security, where it means examining an area, signal, or body with specialized equipment. Scanning has an unusually literal history: before electronic scanners existed, writers and teachers were already scanning lines of poetry to analyse their structure.
To inspect, search, or read something quickly or systematically; to capture or digitize an image, document, or code with a scanner; or, in literary analysis, to examine verse for its metrical structure.
"The application scans each page and converts it into a searchable digital image."
The electronic sense is standard in computing, publishing, security, and medicine. The literary sense refers specifically to analysing metre and rhythm.
The act or process of inspecting, searching, reading, or electronically capturing something.

The noun is usually uncountable when referring to the general process, though plural forms may distinguish separate acts or interpretations.
Usually uncountable for a general activity; the plural is used for separate acts, results, or interpretations, especially of texts or poems.

Where does scanning come from?
Scanning belongs to the English word family of scan and scanner and ultimately traces to Latin scandere, meaning “to climb” or “climb over.” The earliest English use of scan was associated with examining the metre of verse, in which lines are analysed according to rhythmic units. The verb's meaning later broadened to searching or examining material closely, while technological developments gave rise to the sense of electronically capturing images and data.
How scanning is actually used
The literary sense is formal and somewhat specialized. Modern electronic, medical, and security uses are generally neutral and technical, though scanning can sometimes suggest a conspicuously thorough search.
