What are bits defined as?

Bits are defined as binary digits, which are the fundamental building blocks of all digital data. Each bit represents a single binary value, either 0 or 1, and is the smallest unit of data in computing and digital communications. In binary systems, bits are combined in various ways to represent more complex information, including numbers, letters, and other characters. The use of bits allows for the entire range of digital data to be represented within computer systems, making them essential for data processing and storage.

While it is true that bits can be grouped together to form larger units of data, like bytes, the definition identifying them as binary digits is fundamental and captures their essence in the context of computer science and digital communications.
