In communications and also info processing, code is system of regulations to transform info-- such as a letter, word, photo, gesture, or sound-- right into another, occasionally shortened or secret, kind or representation for interaction through a stations or storage in a tool. Speech limits the array of interaction to the range a voice can bring, and limits the audience to those present when the speech is uttered.
The process of encoding converts info from a source right into signs for communication or storage space. Deciphering is the reverse procedure, transforming code signs back right into a form that the recipient understands.
One reason for coding is to enable interaction in position where ordinary plain language, spoken or created, is difficult or difficult. For instance, semaphore, where the configuration of flags held by a signaller or the arms of a semaphore tower encodes parts of the message, typically specific letters and also numbers. Another individual standing a country mile away can interpret the flags and also duplicate words sent out.
Probably the most extensively well-known information communications code so much (a.k.a. character representation) in use today is ASCII. In one or one more (rather compatible) variation, it is used by nearly all individual computers, terminals, printers, and other interaction tools.
