Which term describes the standard for representing text in digital form (e.g., ASCII)?

• A. Character set
• B. ASCII code
• C. Sample rate
• D. Colour depth

Answer: (A)

The main idea is how text is defined and mapped in digital form. A character set is the collection of characters that a system can represent and the codes used to represent them. ASCII is an example of a character set, listing the characters that exist and the numeric codes assigned to each one. So when we talk about representing text like ASCII, we’re referring to the character set. The specific numeric values are the ASCII codes that encode those characters within that set. Other terms refer to different ideas—sample rate is about how often a sound is sampled, and colour depth is about how many bits store color information in an image.
