What term is used to describe a combination of multiple bits?

The term used to describe a combination of multiple bits is "Byte." A byte consists of eight bits and serves as the basic unit of data in computer processing and communication. It represents a single character of data, such as a letter, number, or symbol, in a typical encoding scheme like ASCII. The reason the byte is fundamental in computing is that it provides a standardized way to handle data, enabling systems to efficiently store, process, and transmit information.

While a nibble, which consists of four bits, is also relevant in data representation, it is a smaller unit compared to a byte. A signal refers to the physical transmission of data over a medium, and a frame represents a packet of data transmitted over a network that may contain multiple bytes. Hence, a byte is the most comprehensive term here for describing a combination of multiple bits, making it the correct choice.
