This world is full of questions and we will try to answer a few of them.
Q11. What is a bit? What is a binary code?
Ans. A bit is an elementary unit of the memory. A bit means binary digit, it is the smallest unit of memory.
A binary code is a coding system using the binary digits 0 and 1 to represent a letter, digit , or other character in a computer or other electronic device.
A binary code is a code written in binary language that is, it’s a combination of 0’s and 1’s.
For example, 1101 1001.
