AbbreviationFinder, ASCII is the acronym that corresponds to
the English expression American Standard Code for Information
Interchange. This phrase can be translated as the American
Standard Code for the Exchange of Information. It is a coding
pattern that is used in the field of computing.
The ASCII is basically a character code that
is based on Roman or Latin alphabet. This means that ASCII serves
to convert, through a series of rules, a character that is part of a natural
language (like a letter of an alphabet) into a symbol that
belongs to another class of representative system.
The creation of ASCII occurred in 1963 from
the reformulation of the codes used in telegraphy. Four years
later, lower case letters were added and certain codes were
The American telecommunications company known as AT&T,
of international popularity, at that time was called Bell, and it
provided the data services that promoted the ASCII code. Bell originally
intended to use just six bits, but after joining the American Standards Agency,
whose acronym was ASA, this changed and the seventh bit was added.
For character representation, ASCII uses 7 bits. The
code allows you to define 32 characters that are not printable, followed by 95
printable characters. Being a 7- bit code, it appeals to
strings of bits that can be represented with seven binary digits, which are
decimal between 0 and 127.
When ASCII code first appeared, the most common was the use of groups of
eight bits in computers as the smallest possible unit of information; The last
bit, which was known as the parity bit, used to be
used to control errors in communication lines, although it could also be used
for other functions, depending on the device in question.
Computers that did not use error checking generally assigned
a zero to this bit; however, the Prime series of computers, among
others, placed a one in the eighth bit. It is important to highlight that the
ASCII code does not take into account data such as the appearance or the
structure of the text, since for all this there are certain specific languages,
such as those of labels, but it focuses on the characters and some
control codes that take advantage of word processors.
Specifically, ASCII maps these strings to the symbols they
represent (such as letters and numbers). This makes it easier to store and
process information on a computer (computer) and communication
between different digital devices.
The use of a particular character code is extremely useful to avoid the loss
of information as a consequence of the incompatibility between different
programs; In other words, if we know what code a text document
is based on, we can always interpret it. Of course, this happens automatically
for most users, since the operating system and word processors do not emphasize
the importance of encryption or provide accessible options to manipulate it.
As with most topics specific to the world of technology, advanced users use
software that does allow them to change this and many other aspects of their documents,
although many times they must take certain extra steps to adapt the applications
to their needs..
Artistic manifestations that use this code to create images are
known as ASCII art. By developing drawings with ASCII
characters, artists achieve a very particular optical effect.
