What does a 'bit' represent in computing?

A 'bit' is the most fundamental unit of data in computing and is represented as a binary digit, which can take on one of two values: 0 or 1. This binary system is the foundation of digital computing, enabling all forms of data processing and storage.

While a sequence of bits can form bytes or larger units of data, the definition of a single bit is specifically tied to being either a 0 or a 1. Therefore, identifying a bit as a single unit of data correctly encapsulates its role in representing basic information in digital systems, making it crucial for understanding how computers communicate, store, and process data.
