ASCII code

The abbreviation ASCII stands for American Standard Code for Information Interchange . ASCII is a Unicode that allows encoding characters. Among other things, the code can be used for URL encoding. ASCII is a 7 bit code. It was first published in 1963 and in its final version in 1968.

Structure[ edit ]

A single character, be it letter, digit, or HTML special character , is represented as a number sequence between 00 and 255. This can be represented using 8 bits . However, it is no longer the classic seven-bit ASCII stream.

Character sets[ edit ]

Different sets of characters can be encoded. The default character set, which is always the same, has values ​​from 32 to 127 . Contains uppercase and lowercase alphabet, as well as Arabic numerals and punctuation. Values ​​00-31 are non-printable control characters and the rest are normally for special characters such as î, é, or €. Special characters like German ß or umlauts like ü, ä and ö are possible thanks to the eighth bit, which came later. The task may be different.

Today Unicode UTF-8 has replaced the original ASCII code, as it can represent all characters in human languages ​​using 8 bits.

ASCII table[ edit ]

The characters assigned to the code number appear in a table and can be accessed, for example, at .

ASCII and SEO code[ edit ]

ASCII characters are used today to make search snippets attractive . Check marks, stars, or other characters are stored in meta descriptions and displayed in search results. Therefore, the user’s attention can be specifically directed to search results, which may have a higher CTR result .

ASCII art[ edit ]

Using different character strings, computer artists create images that are also called ASCII art. Actual photos can, for example, be rewritten to ASCII images through programs

The ascii code is an alphanumeric encoding table of the Latin alphabet so that computer systems can store texts.

The name of the ascii code comes from the English acronym American Standard Code for Information Interchange , which translates into Spanish as: American (American) standard code for information exchange.

The ascii code is arranged in a table where each number or combination of numbers corresponds to a capital or lowercase letter, numbers and punctuation symbols adapted to the English language.

In computing, the importance of ascii code lies in that it allowed computers to store texts, since computer systems are only capable of storing numbers. With the character encoding system, systems could translate the numbers into a letter or symbol and then save them in memory.

The first ascii code corresponded to a 7-bit code that generates 128 characters, since computers work with a binary system . Over time, the table and bits expanded, but they did not cover characters from other languages, such as Spanish, for example.

Due to the limitation of ascii code, today it is used for web pages and document codes such as: Latin-1 (ISO-8859-1), UTF-8 and UTF-16.
