Which of the following is the BEST definition of a bit? A physical signal that becomes a digital signe A single 1 or 0 in a digital signal An electrical signal in a wire 256 possible combinations of ones and zeroe

## Step 1<br />A bit, short for binary digit, is the most basic unit of information in computing and digital communications. It is a binary value, which means it can be either a 0 or a 1. <br /><br />## Step 2<br />The bit is the building block of all digital data. It is the smallest unit of data that a computer can process. <br /><br />## Step 3<br />The bit is not a physical signal, nor is it an electrical signal in a wire. It is a binary value, which means it can be either a 0 or a 1. <br /><br />## Step 4<br />The bit is not a combination of 256 possible combinations of ones and zeros. It is a single binary value, either a 0 or a 1.
