What term refers to a character or group of characters used to separate individual items in data?

• A. Duplicate Records
• B. Delimiter
• C. Export
• D. Chart

Answer: (B)

Delimiters are used to separate individual items in data. They act as boundaries that tell a program where one item ends and the next begins. For example, in a CSV file the comma serves as the delimiter, so a line like "Alice,24,Engineer" is parsed into separate fields: Alice, 24, and Engineer. Other common delimiters include tabs in TSV files, semicolons in some locales, or pipes in plain text data. Understanding delimiters helps you see how data is broken into parts so it can be read, parsed, or transformed correctly. The other options refer to different concepts: duplicate records are copies of data rows, export is the action of saving data to a file, and a chart is a visual representation of data.
