What is 2 bit?

1. A 2-bit computer architecture: A 2-bit computer architecture is a type of logic circuit that is capable of processing two binary digits (bits) of data at a time. It can be used for simple calculations and operations, but lacks the complexity and flexibility of modern digital circuits. The first computer to use 2-bit architecture was the UNIVAC 1101 in 1952.

2. Two's complement notation: Two's complement notation is a method of representing signed integers using binary digits. In 2-bit two's complement notation, the range of values that can be represented is -2 to 1. The first bit denotes the sign of the number, with a 0 representing positive and a 1 representing negative. The remaining bits are used to represent the magnitude of the number in binary form. For example, 00 represents 0, 01 represents 1, 10 represents -2, and 11 represents -1.
