Computers employ encoding techniques for storing and retrieving relevant data. This is also known as data encryption.
Data encryption involves specific coding strategies that consist of a sequence of electrical patterns that represent every item of data to be saved and later retrieved. For example, a sequence of electrical patterns is"A. "A." Data encoding and decoding occurs utilizing electronic signals as well as the electrical or electromagnetic encoded data.
In the process of data encoding, the data is serialized or transformed into a string consisting of ones and zeros and transmitted via a communications medium. Serialization must be done in such a way that the computer receiving the data can convert the data back into its original format.
Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 comes from a particular encoding of MIME content transfer encoding.
Basically, base-64 it is a way to encode arbitrary binary data in ASCII text. It takes 4 characters per 3 bytes of data, plus probably a bit of padding at he end.
Essentially every six bits of the input are encoded in an alphabet of 64 characters. The "ordinary" alphabet uses the character A-Z, a-z, 0-9 and + and/or = as padding. The variants are URL-safe.
URL encoding is a method for encoding information in an Uniform Resource Identifier (URI), allowing ASCII character set to send URLs over the Internet. Since URLs frequently contain characters outside of the ASCII set, the URL must be translated into an ASCII format that is valid. URL encoding replaces unsafe ASCII characters with two hexadecimal digits followed by a "%".
The encoder / decoder for the URL is useful when passing a url as a query string. Although most browsers understand non-encoded URIs, this may lead to errors in validation.
If you have to include specific characters within your URL, you'll have to encode them so that the URL stays valid. This can be accomplished using URL Encode. In contrast, if the URL has unique characters and is encoded, but you wish to display it in a human-readable form, you can use the URL decode to create a standard for the URL.
Character encoding is expressing a single character using a set of symbols and data corresponding to that character. There are numerous uses for character coding. A character set or character map are other names for character encoding.
An encoding defines a mapping between bytes and text, and different textual interpretations are possible from a sequence of bytes. We describe how the sequence of bytes is to be interpreted by supplying a specific encoding (like UTF-8).
