Brief History of ASCII code:

The American Standard Code for Information Interchange, or ASCII code, was created in 1963 by the "American Standards Association" Committee or "ASA", the agency changed its name in 1969 by "American National Standards Institute" or "ANSI" as it is known since.

This code arises from reorder and expand the set of symbols and characters already used in telegraphy at that time by the Bell company.

At first only included capital letters and numbers , but in 1967 was added the lowercase letters and some control characters, forming what is known as US-ASCII, ie the characters 0 through 127.
So with this set of only 128 characters was published in 1967 as standard, containing all you need to write in English language.

In 1981, IBM developed an extension of 8-bit ASCII code, called "code page 437", in this version were replaced some obsolete control characters for graphic characters. Also 128 characters were added , with new symbols, signs, graphics and latin letters, all punctuation signs and characters needed to write texts in other languages, ​​such as Spanish.
In this way was added the ASCII characters ranging from 128 to 255.

IBM includes support for this code page in the hardware of its model 5150, known as "IBM-PC", considered the first personal computer.
The operating system of this model, the "MS-DOS" also used this extended ASCII code.
Almost all computer systems today use the ASCII code to represent characters and texts. (346) .

How to use the ASCII code:

Without knowing it you use it all the time, every time you use a computer system, but if all you need is to get some of the characters not included in your keyboard should do the following, for example:

How typing: Spanish letter enye, uppercase N with tilde, EÑE, enie ?

• WINDOWS: on computers with Windows operating system like Windows 8, Win 7, Vista, Windows XP, etc..

  To get the letter, character, sign or symbol "Ñ" : ( Spanish letter enye, uppercase N with tilde, EÑE, enie ) on computers with Windows operating system:

  1) Press the "Alt" key on your keyboard, and do not let go.
  2) While keep press "Alt", on your keyboard type the number "165", which is the number of the letter or symbol "Ñ" in ASCII table.
  3) Then stop pressing the "Alt" key, and ...you got it! (347)
