What are ASCII symbols?
El North American Standard Code for Information Interchange (ASCII) was introduced by Robert W. Bemer for compatibility between different computer manufacturers. This is a series of codes to represent alpha-numeric characters (that is, letters, symbols, numbers, and accents). This code uses a decimal scale that goes from 0 to 127. These numbers are later converted by the computer into binary numbers and thus processed.
How to write ASCII codes?
ASCII codes are written by pressing the alt key on the keyboard in combination with a numeric code corresponding to the specific code we want to write.
Here is a very useful selection of symbols in ASCII:
