What is the difference between a “line feed” and a “carriage return”?

Question

If there are these two keywords then they must have their own meaning. So I want to know what makes them different and what is their code?

Answer 1

Since I can not comment because of not having enough reward points I have to answer to correct answer given by @Burhan Khalid.
In very layman language Enter key press is combination of carriage return and line feed.
Carriage return points the cursor to the beginning of the line horizontly and Line feed shifts the cursor to the next line vertically.Combination of both gives you new line(\n) effect.
