Answer :

Final answer:

Letters on a page or electronic screen are represented by fonts (a combination of typeface and other qualities), typefaces (the design of the characters), and pixels (the smallest basic unit of programmable color on a digital display). Hex numbers, while related to digital display, define colors rather than letters.

Explanation:

When we see letters on a page or an electronic screen, they are composed of different fonts, or more accurately, they are represented by typefaces and pixels. Fonts refer to the combination of typeface and other qualities, such as size, pitch, and spacing. Typefaces describe the design of the characters, for example, Arial, Times New Roman or Helvetica.

On the other hand, pixels are the smallest basic unit of programmable color on a digital display. Letters that we see on the screen are composed of many pixels. Each pixel can be a different color, and collectively they create the visual representation of a letter.

While hex numbers relate to digital display, they are not used to represent the letters directly. Instead, they are often used to define colors in web pages.
