Binary-to-text encodingRepresentation of binary data as text A binary-to-text encoding is a data encoding scheme that represents binary data as plain text. Generally, the binary data consists of a sequence of arbitrary 8-bit byte (a.k.a. octet) values and the text is restricted to the printable character codes of commonly-used character encodings such as ASCII.
8-bit cleanIn computer networking, a system is 8-bit clean if it processes 8-bitcharacter encodings without altering the high bit or treating any byte as an in-band control code. This property can describe both a communications protocol and the software and devices that implement such protocols. Although many early email systems only supported 7-bit data, the vast majority of modern email systems are 8-bit clean.
Base64Base64 is a binary-to-text encoding that uses 64 printable characters to represent each 6-bit segment of a sequence of byte values. As for all binary-to-text encodings, Base64 encoding enables transmittingbinary data on a communication channel that only supports text. When comparing the original data to the resulting encoded data, Base64 encoding increases the size by 33% plus about 4% additional if inserting line breaks for typical line length.YEncyEnc is a binary-to-text encoding scheme for transferring binary files in messages on Usenet or via e-mail. It reduces the overhead over previous US-ASCII-based encoding methods by using an 8-bit encoding method. yEnc's overhead is often (if each byte value appears approximately with the same frequency on average) as little as 1–2%, compared to 33–40% overhead for 6-bit encoding methods like uuencode and Base64.MIMEMultipurpose Internet Mail Extensions (MIME) is a standard that extends the format of email messages to support text in character sets other than ASCII, as well as attachments of audio, video, images, and application programs. Message bodies may consist of multiple parts, and header information may be specified in non-ASCII character sets.
Character encodingCharacter encoding is a convention of using a numeric value to represent each character of a writing script. Not only can a character set include natural languagesymbols, but it can also include codes that have meanings or functions outside of language, such as control characters and whitespace. Character encodings have also been defined for some constructed languages. When encoded, character data can be stored, transmitted, and transformed by a computer.
EmailElectronic mail (usually shortened to email; alternatively hyphenated e-mail) is a method of transmitting and receiving digital messages using electronic devices over a computer network. It was conceived in the late–20th century as the digital version of, or counterpart to, mail (hence e- + mail).
Mary Ann HortonMary Ann Horton (born Mark R. Horton, November 21, 1955), is a Usenet and Internet pioneer.UUCPUUCP (Unix-to-Unix Copy) is a suite of computer programs and protocols allowing remote execution of commands and transfer of files, email and netnews between computers. A command named uucp is one of the programs in the suite; it provides a user interface for requesting file copy operations.
UsenetWorldwide computer-based distributed discussion systemUsenet (), short for User's Network, is a worldwide distributed discussion system available on computers. It was developed from the general-purpose Unix-to-Unix Copy (UUCP) dial-upnetwork architecture. Tom Truscott and Jim Ellis conceived the idea in 1979, and it was established in 1980. Users read and post messages (called articles or posts) to one or more topic categories, known as newsgroups.
UnixUnix ( , YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, the development of which started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
University of California, BerkeleyPublic university in Berkeley, CaliforniaThe University of California, Berkeley (UC Berkeley, Berkeley, Cal, or California) is a publicland-grantresearch university in Berkeley, California, United States. Founded in 1868 and named after the Anglo-Irish philosopher and plantation owner George Berkeley, it is the state's first land-grant university and the founding campus of the University of California system. Berkeley has an enrollment of more than 45,000 students.CodeIn communications and information processing, a code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium. An early example of a code is language, which enables a person, through speech, to communicate what they think, see, hear, or feel to others.*As an Amazon Associate I earn from qualifying purchases.
