AppleLink Package
The AppleLink Package Compression Format, or AppleLink Package for short, is an obsolete file format used on Apple Inc.'s defunct AppleLink online service as a file transfer and file compression format. It was not particularly efficient and was easily outperformed by contemporary systems like StuffIt and Compact Pro Compact Pro is a software data compression utility for archiving and compressing files on the Apple Macintosh platform. It was a major competitor to StuffIt in the early 1990s, producing smaller archives in less time, able to create self-extrac ..., and remained rare outside AppleLink.

File Format
A file format is a Computer standard, standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary format, proprietary or open format, open. Some file formats are designed for very particular types of data: Portable Network Graphics, PNG files, for example, store Raster graphics, bitmapped Graphics file format, images using lossless data compression. Other file formats, however, are designed for storage of several different types of data: the Ogg format can act as a container format (digital), container for different types of multimedia including any combination of sound, audio and video, with or without text (such as subtitles), and metadata. A text file can contain any stream of characters, including possible control characters, and is encoded in one of various Character encoding, character encoding schemes. Some file formats, such as HTML, sca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Inc
Apple Inc. is an American multinational corporation and technology company headquartered in Cupertino, California, in Silicon Valley. It is best known for its consumer electronics, software, and services. Founded in 1976 as Apple Computer Company by Steve Jobs, Steve Wozniak and Ronald Wayne, the company was incorporated by Jobs and Wozniak as Apple Computer, Inc. the following year. It was renamed Apple Inc. in 2007 as the company had expanded its focus from computers to consumer electronics. Apple is the largest technology company by revenue, with billion in the 2024 fiscal year. The company was founded to produce and market Wozniak's Apple I personal computer. Its second computer, the Apple II, became a best seller as one of the first mass-produced microcomputers. Apple introduced the Lisa in 1983 and the Macintosh in 1984, as some of the first computers to use a graphical user interface and a mouse. By 1985, internal company problems led to Jobs leavin ...

AppleLink
AppleLink was the name of both Apple Computer's online service for its dealers, third-party developers, end users, and the client software used to access it. Prior to the commercialization of the Internet, AppleLink was a popular service for Mac and Apple IIGS users. The service was offered from about 1986 to 1994 to various groups, before being superseded by their short-lived eWorld and finally today's multiple Apple websites. Early years The original AppleLink, which went online in 1985, was a service available only to Apple employees and dealers, and shortly thereafter to Apple University Consortium members. Apple's consumer 800 number in fact touted this fact, promoting your dealer as the place to turn for help because of his access to AppleLink. In the late 1980s the service was also opened up to software developers, who could use it both as an end-user support system as well as a conduit to Apple development for questions and suggestions. AppleLink used client software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Online Service
An online service provider (OSP) can, for example, be an Internet service provider, an email provider, a news provider (press), an entertainment provider (music, movies), a search engine, an e-commerce site, an online banking site, a health site, an official government site, social media, a wiki, or a Usenet newsgroup. In its original more limited definition, it referred only to a commercial computer communication service in which paid members could dial via a computer modem the service's private computer network and access various services and information resources such as bulletin board systems, downloadable files and programs, news articles, chat rooms, and electronic mail services. The term "online service" was also used in references to these dial-up services. The traditional dial-up online service differed from the modern Internet service provider in that they provided a large degree of content that was only accessible by those who subscribed to the online service, whi ...

File Transfer
File transfer is the transmission of a computer file through a communication channel from one computer system to another. Typically, file transfer is mediated by a communications protocol. In the history of computing, numerous file transfer protocols have been designed for different contexts. Protocols A file transfer protocol is a convention that describes how to transfer files between two computing endpoints. As well as the stream of bits from a file stored as a single unit in a file system, some may also send relevant metadata such as the filename, file size and timestamp – and even file-system permissions and file attributes. Some examples: * FTP is an older cross-platform file transfer protocol * SSH File Transfer Protocol In computing, the SSH File Transfer Protocol, also known as Secure File Transfer Protocol (SFTP), is a network protocol that provides file access, file transfer, and file management over any reliable data stream. It was designed by the In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Compression
In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder. The process of reducing the size of a data file is often referred to as data compression. In the context of data transmission, it is called source coding: encoding is done at the source of the data before it is stored or transmitted. Source coding should not be confused with channel coding, for error detection and correction or line coding, the means for mapping data onto a signal ...

StuffIt
StuffIt is a discontinued family of computer software utilities for archiving and compressing files. Originally produced for Macintosh, versions for Microsoft Windows, Linux (x86), and Sun Solaris were later created. The proprietary compression format used by the StuffIt utilities is also termed StuffIt. In December 2019, Smith Micro Software, the product's most-recent owner and developer, officially announced that StuffIt had reached its end-of-life and that StuffIt products would no longer be developed. One last update did come out in December 2020 after the launch of the Apple M1 architecture to support that and Intel Mac systems through a universal binary of the program. Overview StuffIt was originally developed in the summer of 1987 by Raymond Lau, who was then a student at Stuyvesant High School in New York City. It combined the fork-combining capabilities of utilities such as MacBinary with newer compression algorithms similar to those used in ZIP. Compared to exist ...

Compact Pro
Compact Pro is a software data compression utility for archiving and compressing files on the Apple Macintosh platform. It was a major competitor to StuffIt in the early 1990s, producing smaller archives in less time, able to create self-extracting archives without the use of an external program, as well as being distributed via shareware which greatly helped its popularity. A PC version was also available, ExtractorPC. Neither program is actively supported. History When it was introduced in the early 1990s, Compact Pro (originally known as "Compactor") competed against StuffIt, which had been suffering from neglect after its original developer moved on to other projects. Compact Pro sported a clean interface and a variety of new features which quickly made it a favorite among the digerati. It quickly drove StuffIt from the leadership position and became very popular on BBS systems. StuffIt 3.0 fought back with an even more powerful compression algorithm, a shareware version ...
