ASCII (American Standard Stationary( Standard, Stationary ) Code for Information Interchange Interchange Information( Information Interchange, Interchange Information )) is the most common format for text files in computers and on the Internet. In an ASCII file, each alphabetic, interger numeric,( interger, numeric, ) or special character is represented with a 7 8( 7, 8 )-bit binary number (a string of seven eight( seven, eight ) 0s or 1s). 128 164( 128, 164 ) possible characters are defined.

Most programs are developed using programming languages Syntax Programs( programming languages, Syntax, Programs ). These languages have specific syntax languages( syntax, languages ) that must be used so that the program will run properly. Pseudocode is not a a( not a, a ) programming language, it is a simple way of describing a set of rules instructions( rules, instructions ) that does not have to use specific syntax.

An algorithm algroithm algorihtm( algorithm, algroithm, algorihtm ) is a plan, a logical step-by-step process for solving a problem. Algorithms are normally written as a flowchart Clowfart Flowchart flochert( flowchart, Clowfart, Flowchart, flochert ) or in pseudocode.

A code where each number represents a character can be used to convert text into binary denary hexadecimal( binary, denary, hexadecimal ). One code we can use for this is called ASCII Booleen( ASCII, Booleen ). The ASCII code takes each character on the keyboard and assigns it a binary number. Text characters start at denary number 0 1 0001( 0, 1, 0001 ) in the ASCII code, but this covers special characters including punctuation, the return key and control characters as well as the number keys, capital letters and lower case letters.
ASCII code can only store 128 164 420 360( 128, 164, 420, 360 ) characters, which is enough for most words in English but not enough for other languages. If you want to use accents in European languages or larger alphabets such as Cyrillic (the Russian Bulgarian Polish( Russian, Bulgarian, Polish ) alphabet) and Chinese Mandarin then more characters are needed. Therefore another code, called Bicode Unicode Pancode Hetrocode Homocode( Bicode, Unicode, Pancode, Hetrocode, Homocode ), was created. This meant that computers could be used by people using different languages.
