Scanner is a versatile term with three common meanings. First, a hardware device that reads codes, text, or images by scanning, commonly seen at stores as a barcode scanner or a document scanner. Second, a medical imaging machine such as a CT or MRI scanner that creates internal pictures of the body. Third, a software program that checks files or systems for viruses or malware, often called an antivirus scanner or malware scanner. In everyday English, you will hear phrases like handheld scanner, flatbed scanner, MRI scanner, or virus scanner. Learners often confuse the noun with the verb "to scan" or misplace where to use "scanner" vs "scanning." Pronunciation stresses first syllable: SCAN-ner.
