scanner
To look over something quickly or to use a machine to copy a document into a computer.
Explanation at your level:
When you scan, you look at a page fast. You look for one word. You can also use a machine. The machine makes a digital copy of your paper.
You scan a text to find information quickly. For example, you scan a menu to find the price. You can also scan a document at work to send it by email.
To scan means to search through text or an area. It is different from 'reading' because you don't read every word. In technology, we scan documents to save them as PDFs.
The verb scan is versatile. It describes the rapid visual search for data, like scanning a barcode or a crowd. It also refers to the digital conversion process where hardware creates a high-resolution image.
In an academic context, scanning is a vital research skill, allowing scholars to process vast amounts of literature efficiently. Beyond the physical, it can imply a figurative 'scanning' of a situation to assess potential risks or outcomes.
Etymologically, scan bridges the gap between the rhythmic analysis of verse and the modern digital paradigm. Its usage spans from the tactile act of searching a physical space to the complex technical operations of medical imaging devices like MRI scanners.

When you scan something, you are essentially performing a quick search. Think of it like a lighthouse beam sweeping across the ocean; it doesn't stop to look at every single wave, but it catches the important things.
In the digital age, we use the word to describe using a scanner device. You place a photo on the glass, and the light moves across it to turn that physical memory into a digital file on your screen.
The word scan comes from the Latin word scandere, which originally meant 'to climb.' It sounds strange, right? But think of it as 'climbing' through a text line by line.
In poetry, it referred to measuring the rhythm of a line. Over time, it evolved into the modern sense of looking over something quickly, and eventually, the technical sense of electronic scanning was added in the 20th century.

In casual conversation, you might say, 'I scanned the room for my friend.' It implies you are looking for one specific thing amidst a busy background.
