What is the bit in computer?

Excuse me, could you please clarify what you mean by "the bit in computer"? Are you referring to the fundamental unit of digital information in computing, which is often abbreviated as "bit"? If so, a bit is a binary digit that can have a value of either 0 or 1. It serves as the basic building block of all digital information, including data stored in computer memory and transmitted over networks. Computers process and manipulate information by performing operations on bits, which are grouped together to form larger units of data such as bytes, kilobytes, and megabytes. Is this what you were asking about?
