Final answer:
A group of eight bits is called a byte according to the American Standard Code for Information Interchange (ASCII).
Step-by-step explanation:
In the American Standard Code for Information Interchange (ASCII), a group of eight bits is called a byte. A byte is the smallest addressable unit of data in computer storage and represents a single character, such as a letter, number, or symbol.
ASCII assigns a unique numerical value to each character, ranging from 0 to 127. The representation of a character as a byte allows computers to process and transmit data in a standardized format, ensuring compatibility across different systems.
