ASCII Code Printable Characters
In computer language it is important to understand how the different devices that we use daily work, nothing is by coincidence and there have been years of work so that, for example, you can read this article today.
ASCII is a standard code United States for the Exchange of Information in accordance with its acronym in English, created as a method for standardizing computing devices.
Table of printable characters and ASCII code symbols

What are printable ASCII code characters?
The ASCII code is a symbol set they are assigned in a table for the correct operation of the devices and are divided into several positions that computers are only able to understand numbers.
Unlike the ASCII code control characters, the printable characters of ASCII code are those that we can print, such as letters, numbers, symbols, among others.
The printable characters of ASCII code is a numerical representation that has been previously assigned in a table with symbols and codes numbers previously, that is, it is in charge of passing information between the user and the computer.
The codes assigned in these tables ranging from 32 to 126 correspond to the printable ASCII code characters that are to be represented on the screen as letters, digits, different symbols, digits and punctuation marks.
There are seven-bit ASCII, the ASCII that commits the eighth bit belongs to the extended ASCII code characters.
Also used or called, within the spectrum in this table of printable ASCII code characters, the character "space", which is made with a different representation that does not have symbols, but a blank space.
These arose from the need for the transfer of information from one device to another to be faster and more universal.
This is because, at the beginning of the encoding of the various devices, all the codes, including the printable characters of ASCII code, were different on each of the computers that you will use.
So the way you could see or read a file on your computer it was not the same as another, making the information pass slower and clumsier.
This clumsiness for share information, send files and somehow, working efficiently and also effectively, made it impossible for working hours to be productive, hence the need to create a universal system that encompasses everything necessary for the efficient transfer of information.
What are they used for?
The printable ASCII code characters, as we mentioned before, are the ones we can see, the ones that allow us to read and write these articles and provide us with fluid communication.
That is to say, thanks to the symbols as to the signs, such as opening a parenthesis "(" if it were represented by the number 28, then every time we go to open a parenthesis in a text, the computer receives as information in its programming one of the printable ASCII code characters as 28, and if we do it followed as “(((“ it renders it as 282828 so we can see “(((“.
Exactly the same thing happens with the letters, at first they were only uppercase letters and later they evolved to lowercase.
The letter "m" if it were represented by the number 77 and the letter "a" was represented by the number 41 to write the word "mama" we execute it in a human way through the hardware and press the keys while internally it is represented like 77417741.
In this way, it is possible to pass information quickly and accurately.
How are ASCII code printable characters used?
It is not necessary to know how to use printable ASCII code characters professionally, in fact, we use them daily and we don't even realize it.
A very clear example is the moment you used your search engine to type the letters that put together the necessary phrase for you to reach this article.
When you type the phrase, thousands of numbers were internally assigned that were pre-encoded and achieved through a programming language put together the sentence
These characters that have been assigned in the table previously include codes and symbols in addition to letters, so every time we use them to communicate as we are doing.
So, if we go to a perhaps a little more complicated example involving signs, and we want to write “mama?, the open question mark “” would be 23 and the closed question mark “?” were 24, the result would be 237741774124 so that the screen reads “mama?”
Note then, that in the examples, despite wanting to write the word mom, the printable characters only include those that are not special, so the "á" is not part of a printable character, but rather an extended one.
On Mac
To use these characters on MAC, you can do it in two ways, the first is to do it through keyboard shortcuts ctrl + CMD + space.
The second is to click on system preferences, followed by keyboard and you will look for the option to “show keyboard and Emoji viewers in the menu bar”
Next, it will show you a symbol in the upper right, you must click on that symbol and select "show keyboard viewer"
After this, regardless of the two forms, a keyboard will appear, here you will have the option to see all the characters at once.
On windows
You can make use of one of the control characters and through the “WIN” key or menu, to display the start.
Once there, what you are going to do is enter the word “charmap” in the search bar and there you will be able to access and view all the printable characters, after this you only have to select the one you need.
On Linux
On Linux you can easily access this character map as it is usually part of the desktop.
You go to the Linux terminal and type Gucharmap in the search engine and you will automatically have access to the entire table with absolutely all the printable characters. Or you can select at home, apps, then accessories and character map.
In this way you can take advantage of what all operating systems provide you.
