Currently, we can find a wide range of computers that vary in their functions depending on the tasks that are required. At present, there are many companies that compete every day to develop more powerful computers and laptops, and because of this, many people forget how computers worked in the beginning.
The truth is that the operation of a computer depends in the first instance on a fairly complex language based mainly on the implementation of a series of codes. At first, computers used a simple language where binary codes were the most used, that is, they only understood the use of 0 and 1. These digits were called bits, while the set of eight of them were called bits. called byte.
When sending some data by means of a computer, certain keys on the keyboard are pressed and the text resulting from this action is sent and also received in a set made up of digits. All of these make up the characters that were generated when the text was being written.
ASCII also known as ascii code made its first appearance long before the advent of the Internet, in fact, at the time of mechanical printers and teletypes it already existed. It is essential to make it clear that said code is used on computers that are not so powerful or with little measure to understand and at the same time transmit text data. For this reason, ASCII transforms information into a kind of generalized digital format that allows computers to communicate with each other and, in turn, process and also store a certain amount of data in a more efficient way.
What do you need:
- Basic and intermediate knowledge of computers.
- Interest in learning new topics, especially if you like technology.
- If you are a lover of computer-related topics and want to know a little more about this code, then you just have to read the whole post.
Instructions
- ASCII is a code made up of digits that represent characters, using a decimal scale that goes from 0 to 127. The computer transforms these decimal digits into binary to be processed later. Which means that all the text that is written will correspond to a code.
- The ASCII code comes from English which means American Standard Code for Information Interchange. We can translate it into Spanish as the North American Standard Code for Information Interchange. This code was created during the second world war in 1945 to be more specific and it was Robert W. Bemer who made the proposal. At that time, a method was necessary that was standard and also reliable enough for the telegraph system, this in order to transmit more information in a safer and clearer way.
- Bell Laboratories were in charge of working on it until they could develop a system that allowed the sending of messages thanks to the telegraph. At that time, the question that was repeated the most was how to go from Morse code to computers. However, the answer was not as difficult as many thought, because the two techniques share something in common, it is the binary system. With respect to the telegraph, the elements that made it up were silence and the audible signal, in this case both elements could be considered as binary ones and zeros.
- 20 years passed before the foundations of what is known as the ascii code were finally laid, this after the AESC and the American Engineering Standards Committee made it official. In its beginnings, the Ascii code only contained numbers and uppercase letters, however, thanks to constant revisions, the inclusion of lowercase letters and also one or another additional character became possible. It is very important to emphasize that the last revision made to the ASCII code was in 1986.
- At present, the ASCII code only uses a total of 7 bits in order to constitute each of the characters, however, during its beginnings it used only 1 additional bit which was called “parity”, this was used when required in troubleshooting during data transmission.
- The ASCII code has become so important in the area of computing, that it can be said that it is not possible to use a computer or any type of electronic device without said code being present, this means that regardless of the time in which we we find today, the ASCII code is still essential in many computing procedures.
- Although many people do not take it into account, if this code did not exist it is impossible that at this moment we could carry out simple tasks such as writing on the computer or reading this post. It is thanks to the ASCII code that today we can do this kind of thing, in other words, encode a variety of combinations of symbols and characters, which computers use internally to manage texts in indications, words and letters that all As people can understand, all of this makes using a computer so easy that anyone can do it.
- In fact, it could be said that ASCII is not just a code, but a kind of universal computer language, not in the realm of programming language directly, it goes beyond the inside of the device, right in the place where the binary system does that each of our instructions is translated into a language that is easy to understand not only for the devices but also for the different processors.
- Binary language is what gives life to a computer, allowing it to carry out various tasks, it is capable of translating all the instructions that we order to the same device and the opposite also occurs, in other words, the responses that we receive from the computer, mobile device or Tablet.
- Although it seems a bit strange, the ASCII code is not only used in the field of computing, in various parts of the world there are people who have become known for using this type of coding to make art, if you read correctly, art. What at first began as a simple experiment for the creation of art through new technologies, the truth is that today there are few artists who dedicate themselves fully to this type of art, however, in the same way we are before a specialty that little by little is growing. In general, this class of artists carry out their creations through software specially dedicated for tasks like this, however, the most refined assure that the true essence corresponding to this class of art is found in the direct creation through an editor of texts.
Tips
- To know a little more about the types of encryption that exist, you need to carry out a deeper investigation.
- If you are interested in codes like ASCII, you can use an old computer so you can do various practices.
- Computer science is a specialty that should preferably be studied academically, however, on the Internet you can find a large number of tutorials that will help you learn the most basic and then increase the level.
