Package Format
Package format is a type of archive containing computer programs and additional metadata needed by package managers; an instance of this type of archive is called a package. While the archive file format itself may be unchanged, package formats carry additional metadata, such as a manifest file or certain directory layouts. Packages may contain either source code or executable files. Packages may be converted from one type to another with software such as Alien. Software supply chain and security Packages are an important component in managing the security and integrity of the software supply chain. Packages containing executables and configuration can be digitally signed to establish the integrity of running software and protect against tampering. Package formats that support code signing include .deb (Debian), .msi (Microsoft Windows), .apk ( Android) and .ipa (IOS, IPadOS). Common formats Specialized formats BSD-based formats Linux-based formats Windows f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archive File
In computing, an archive file stores the content of one or more files, possibly compressed, with associated metadata such as file name, directory structure, error detection and correction information, commentary, compressed data archives, storage, and sometimes encryption. An archive file is often used to facilitate portability, distribution and backup, and to reduce storage use. Applications Portability As an archive file stores file system information, including file content and metadata, it can be leveraged for file system content portability across heterogeneous systems. For example, a directory tree can be sent via email, files with unsupported names on the target system can be renamed during extraction, timestamps can be retained rather than lost during data transmission. Also, transfer of a single archive file may be faster than processing multiple files due to per-file overhead, and even faster if compressed. Software distribution Beyond archiving, archi ...

FreeBSD Ports
The FreeBSD Ports collection is a package management system for the FreeBSD operating system. Ports in the collection vary with contributed software. There were 38,487 ports available in February 2020 and 36,504 in September 2024. It has also been adopted by NetBSD as the basis of its pkgsrc system. Installing from source The ports collection uses Makefiles arranged in a directory hierarchy so that software can be built, installed and uninstalled with the make command. When installing an application, very little (if any) user intervention is required after issuing a beginning command such as make install or make install clean in the ports directory of the desired application. In most cases the software is automatically downloaded from the Internet, patched and configured if necessary, then compiled, installed and registered in the package database. If the new port has needed dependencies on other applications or libraries, these are installed beforehand automatically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Android App Bundle
Android App Bundle is the Android application publishing file format. The App Bundle must include the application's compiled code and resources, which allows for the signing and generation of APK files to be deferred to the app store, reducing the initial download size of the app. The file extension used for this format is ".aab". Google Play requires Android App Bundles for all new apps since August 2021 and for all updates to preexisting apps since November 2021. Since May 2023, Android TV requires AABs. Split APKs Without Android App Bundles, an APK can support multiple languages, up to four different CPU architectures, and several display resolutions. This meant that each installation file could contain potentially large amounts of bloat irrelevant for a device's specific combination of CPU, locale, and screen size. Split APKs, which are generated by an app store like Google Play, contain only the code and resources that are needed for the specific device downloading ...

Apple Newton
The Newton is a specified standard and series of personal digital assistants (PDAs) developed and marketed by Apple Inc., Apple Computer, Inc. from 1993 to 1998. An early device in the PDA categorythe term itself originating with the Newtonit was the first to feature handwriting recognition. Newton devices run on a proprietary operating system, Newton OS; unlike the company's Mac (computer), Macintosh computers, Apple licensed the software to third-parties, who released Newton devices alongside Apple's own MessagePad line. Apple started developing the platform in 1987; concepted by Steve Sakoman as a Tablet computer, tablet-like device with handwriting capabilities, he worked with AT&T Corporation to develop a low-power processor, AT&T Hobbit, Hobbit, for the project. However, slow progress and other issues led to Sakoman leaving Apple in 1990 to form Be Inc., Be Computer, Inc. The Newton project would be revitalized by Michael Tchao and Steve Capps who pitched the idea directly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BeOS
BeOS is a discontinued operating system for personal computers that was developed by Be Inc. It was conceived for the company's BeBox personal computer which was released in 1995. BeOS was designed for multitasking, multithreading, and a graphical user interface. The OS was later sold to OEMs, retail, and directly to users; its last version was released as freeware. Early BeOS releases are for PowerPC. It was ported to Macintosh, then x86. Be was ultimately unable to achieve a significant market share and ended development with dwindling finances, so Palm acquired the BeOS assets in 2001. Enthusiasts have since created derivate operating systems including Haiku, which will retain BeOS 5 compatibility as of Release R1. Development BeOS is the product of Apple Computer's former business executive Jean-Louis Gassée, with the underlying philosophy of building a "media OS" capable of up-and-coming digital media and multi-processors. Development began in the early 1990s, initially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symbian
Symbian is a discontinued mobile operating system (OS) and computing platform designed for smartphones. It was originally developed as a proprietary software OS for personal digital assistants in 1998 by the Symbian Ltd. consortium. Symbian OS is a descendant of Psion's EPOC, and was released exclusively on ARM processors, although an unreleased x86 port existed. Symbian was used by many major mobile phone brands, like Samsung, Motorola, Sony Ericsson, and above all by Nokia. It was also prevalent in Japan by brands including Fujitsu, Sharp and Mitsubishi. As a pioneer that established the smartphone industry, it was the most popular smartphone OS on a worldwide average until the end of 2010, at a time when smartphones were in limited use, when it was overtaken by iOS and Android. It was notably less popular in North America. The Symbian OS platform is formed of two components: one being the microkernel-based operating system with its associated libraries, and the othe ...

UNIX System V
Unix System V (pronounced: "System Five") is one of the first commercial versions of the Unix operating system. It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, numbered 1, 2, 3, and 4. System V Release 4 (SVR4) was commercially the most successful version, being the result of an effort, marketed as ''Unix System Unification'', which solicited the collaboration of the major Unix vendors. It was the source of several common commercial Unix features. System V is sometimes abbreviated to SysV. , the AT&T-derived Unix market is divided between four System V variants: IBM's AIX, Hewlett Packard Enterprise's HP-UX and Oracle's Solaris, plus the free-software illumos forked from OpenSolaris. Overview Introduction System V was the successor to 1982's UNIX System III. While AT&T developed and sold hardware that ran System V, most customers ran a version from a reseller, based on AT&T's reference implementation. A ...

SunOS
SunOS is a Unix-branded operating system developed by Sun Microsystems for their workstation and server computer systems from 1982 until the mid-1990s. The ''SunOS'' name is usually only used to refer to versions 1.0 to 4.1.4, which were based on BSD, while versions 5.0 and later are based on UNIX System V Release 4 and are marketed under the brand name '' Solaris''. History SunOS 1 only supported the Sun-2 series systems, including Sun-1 systems upgraded with Sun-2 ( 68010) CPU boards. SunOS 2 supported Sun-2 and Sun-3 ( 68020) series systems. SunOS 4 supported Sun-2 (until release 4.0.3), Sun-3 (until 4.1.1), Sun386i (4.0, 4.0.1 and 4.0.2 only) and Sun-4 ( SPARC) architectures. Although SunOS 4 was intended to be the first release to fully support Sun's new SPARC processor, there was also a SunOS 3.2 release with preliminary support for Sun-4 systems. SunOS 4.1.2 introduced support for Sun's first sun4m-architecture multiprocessor machines (t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solaris (operating System)
Oracle Solaris is a proprietary software, proprietary Unix operating system offered by Oracle Corporation, Oracle for SPARC and x86-64 based workstations and server (computing), servers. Originally developed by Sun Microsystems as Solaris, it superseded the company's earlier SunOS in 1993 and became known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. After the Acquisition of Sun Microsystems by Oracle Corporation, Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris. Solaris was registered as compliant with the Single UNIX Specification until April 29, 2019. Historically, Solaris was developed as proprietary software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris Open-source software, open-source project.
