MalwareMalware (a portmanteau of malicious software) is any software intentionally designed to cause disruption or destruction to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or interfere with the user's computer security and privacy without their knowledge.
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.
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.
ASCIICharacter encoding standardASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English-language–focused) printable and 33 control characters – a total of 128 code points. The set of available punctuation had significant impact on the syntax of computer languages and text markup.
ARPANETThe Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first computer networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the Advanced Research Projects Agency (now DARPA) of the United States Department of Defense.
Shar (file format)In the Unixoperating system, shar (from "shell archive") is an archive format created with the Unix shar utility. A shar file is a type of self-extracting archive, because it is a valid shell script, and executing it will recreate the files. To extract the files, only the standard UnixBourne shellsh is usually required. shar files are also sometimes called "sharchives" (from "/bin/sh archive").
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.
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.BinHexBinHex, originally short for "binary-to-hexadecimal", is a binary-to-text encoding system which was used on the classic Mac OS for sending binary files over email. BinHexed files take up more space than the original files, but avoid data corruption by software that is not 8-bit clean.
Computer fileA computer file is a named collection of data treated as a unit by the system that manages it. Today, this system is called a file system. Many older computer systems lacked a distinct file system per se, yet a management feature is required in order to provide a file abstraction. Files can be shared with and transferred between computers and mobile devices via removable media, networks, or the Internet. Different types of computer files are designed for different purposes.
Simple Mail Transfer ProtocolThe Simple Mail Transfer Protocol (SMTP) is an Internet standardcommunication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages. User-level email clients typically use SMTP only for sending messages to a mail server for relaying, and typically submit outgoing email to the mail server on port 465 or 587 per RFC8314.
Uuencodinguuencoding is a form of binary-to-text encoding that originated in the Unix programs uuencode and uudecode written by Mary Ann Horton at the University of California, Berkeley in 1980, for encodingbinary data for transmission in email systems.*As an Amazon Associate I earn from qualifying purchases.
