What is font smoothing and why would I need it enabled?

Text displayed on screen is really displayed as images in bitmap mode. What this means is that every image is shown by a bunch of tiny little dots (pixels) and so there is really no smooth curve because curved or diagonal lines made up of dots will end up having jagged edges. If this text is magnified, the jaggedness will also be magnified. To solve this problem, programmers use a technique called anti-aliasing, which involves shading the pixels along the edge of curves to create a smooth line. Since the term anti-aliasing applies to both text and graphics, the term "font smoothing" is used to denote anti-aliased text. In simple words, font smoothing makes the magnified text easier to read.
