Coding is called the transformation of the formulation of a message through the rules or norms of a predetermined code or language.
We know encoding as any operation that involves assigning a value of symbols or characters to a certain verbal or non-verbal message with the purpose of transmitting it to other individuals or entities that share the code.
Coding is something as simple as what we do on a daily basis when we transform visual images or conceptual entities into words, sentences, texts and communicate them to those around us. It is also encoding those more complex operations that involve codes shared by fewer interlocutors, such as an encrypted message or information issued through Morse code. Metaphorically, in addition, one can speak of coded messages when they contain a cryptic or unintelligible value for the average public.
In computing, therefore, coding is also that operation that takes place to send data from one place to another, process it and obtain results from it. All computer operations are encrypted in binary code, or more or less complex combinations of ones and zeros that occur constantly.
In turn, certain computer operations require a second level of encryption. They are those that require security and confidentiality aspects and, therefore, imply the creation of encrypted messages that can only be read by certain types of computers or by the user who created them, as happens with passwords and personal data in transactions. online.
This type of encryption has a high reliability value and is used in all types of tasks and computing environments, in matters as simple as creating an account on a social network and as complex as conducting banking and financial operations over the Internet.
