Explanation:

Both Morse code and Braille try to use representations to form text messages.

Morse code is a method of transmitting information in text, using two distinct sound tones, which can only be understood by a qualified listener. The International Morse Code covers the conventional Latin Latin alphabet, some other Roman letters, and Arabic numbers, as well as a small amount of punctuation and standard signs, all of which are possible to be coded using only dots, dashes and spaces.

The Braille code consists of a combination of dots arranged in a cell of three rows and two columns. Through the combination of these symbols, the visually impaired can read and write any type of text. In simpler situations, Braille text can be produced using a special ruler and a stylus that records points on a base that marks the marked places.
