ASCII

We explain to you what the ASII code is and what this code of written characters is for. Complete table with ASCII codes.

The ASCII standard was first published in 1967.
  1. What is ASCII?

In computer science, it is known as ASCII (pronounced aski ) or ASCII code to a code of written characters that is based on the Latin alphabet, identical to the one used by the modern English . It comes from a renewal or reworking of the code used until 1963 in the telegraph, carried out by the American Standards Committee (today the ASA, for its acronym in English). Its name is an acronym for the American Standard Code for Information Interchange or the American Standard Code for the Exchange of Information.

The original ASCII code used 7 bits of information to represent each of the corresponding characters, and an additional bit for error checking (for a total of 8 bits, that is, one byte) . It should not be confused with various current 8-bit codes that extend the ASCII to incorporate signs from languages ​​other than English.

Put more simply, it is a numerical translation of the alphabet used by the English, since computer systems only handle binary code ( 0-1) as a language to represent your logical operations. Thus, each character (letter, sign or even blank space) corresponds in ASCII with an eight-bit number string (eight digits between 0 and 1, that is, in binary code) .

The ASCII standard was first published in 1967 and was updated for the last time in 1986, bringing it to its contemporary version for 32 non-printable characters and 95 Printables that follow them in numbering. This is a code used almost universally by today's computer systems, essential for administering typographic devices, such as keyboards.

As the usage needs of the code increased, extended versions of ASCII were created to facilitate the incorporation of languages ​​other than English and of logical, mathematical or scientific descriptors specialized guys . Even the ASCII art or computer generated images were popularized by the strategic positioning of code chains on the page, which when viewed from afar form figures and drawings
