What are the functions of carriage and keyboard of the typewriter?

The carriage of a typewriter holds the paper in place and moves horizontally as each character is typed, allowing for the sequential printing of letters on the page. It also returns to the starting position after reaching the end of a line, facilitating continuous typing. The keyboard, consisting of keys representing letters, numbers, and symbols, enables the typist to input text by striking the corresponding keys, which activates the typebars or ribbons to imprint characters onto the paper. Together, these components work to transform typed input into written output.
