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-extractin ..., and remained rare outside AppleLink.

File Format
A file format is a 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 or free. Some file formats are designed for very particular types of data: PNG files, for example, store bitmapped 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 for different types of multimedia including any combination of 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 schemes. Some file formats, such as HTML, scalable vector graphics, and the source code of computer software are text files with defined syntaxes that allow them to be used for specific purposes.

Apple Inc
Apple Inc. is an American multinational technology company headquartered in Cupertino, California, United States. Apple is the largest technology company by revenue (totaling in 2021) and, as of June 2022, is the world's biggest company by market capitalization, the fourth-largest personal computer vendor by unit sales and second-largest mobile phone manufacturer. It is one of the Big Five American information technology companies, alongside Alphabet, Amazon, Meta, and Microsoft. Apple was founded as Apple Computer Company on April 1, 1976, by Steve Wozniak, Steve Jobs and Ronald Wayne to develop and sell Wozniak's Apple I personal computer. It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977 and the company's next computer, the Apple II, became a best seller and one of the first mass-produced microcomputers. Apple went public in 1980 to instant financial success. The company developed computers featuring innovative graphical user inter ...

AppleLink
AppleLink was the name of both Apple Computer's online service for its dealers, third-party developers, and 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 w ... [...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, while ...

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 a file transfer protocol secured by the Secure Shell (SSH) protocol * Secure copy (''scp'') is based on the Secure Shell (SSH) protocol * HTTP can support file transfer * Bittorrent, Gnutella and other distributed file transfers systems use peer-to-peer * ...

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 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. Co ...

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 calle ...
