A text is a sequence of words. A text stays the same no matter how it’s rendered. Consider the sentence “I like Learning Code.” I can print that text on a piece of paper, or read it aloud, or save it in a file on my laptop. It’ll be the same text, just rendered different ways—visually, audibly, digitally.
But when “I like Learning code” is printed, typography gets involved. All visually displayed text involves typography—whether it’s on paper, a computer screen, or a billboard.
