Upgradeability
Upgrading is the process of replacing a product with a newer version of the same product. In computing and consumer electronics an upgrade is generally a replacement of hardware, software or firmware with a newer or better version, in order to bring the system up to date or to improve its characteristics. Computing and consumer electronics Examples of common hardware upgrades include installing additional memory (RAM), adding larger hard disks, replacing microprocessor cards or graphics cards, and installing new versions of software. Many other upgrades are possible as well. Common software upgrades include changing the version of an operating system, of an office suite, of an anti-virus program, or of various other tools. Common firmware upgrades include the updating of the iPod control menus, the Xbox 360 dashboard, or the non-volatile flash memory that contains the embedded operating system for a consumer electronics device. Users can often download software and firmware u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and development of both hardware and software. Computing has scientific, engineering, mathematical, technological and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology and software engineering. The term "computing" is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. Computing is intimately tied to the representation of numbers, though mathematical conc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emerging Technologies
Emerging technologies are technologies whose development, practical applications, or both are still largely unrealized. These technologies are generally new but also include older technologies finding new applications. Emerging technologies are often perceived as capable of changing the status quo. Emerging technologies are characterized by radical novelty (in application even if not in origins), relatively fast growth, coherence, prominent impact, and uncertainty and ambiguity. In other words, an emerging technology can be defined as "a radically novel and relatively fast growing technology characterised by a certain degree of coherence persisting over time and with the potential to exert a considerable impact on the socio-economic domain(s) which is observed in terms of the composition of actors, institutions and patterns of interactions among those, along with the associated knowledge production processes. Its most prominent impact, however, lies in the future and so in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System Restore
System Restore is a feature in Microsoft Windows that allows the user to revert their computer's state (including system files, installed applications, Windows Registry, and system settings) to that of a previous point in time, which can be used to recover from system malfunctions or other problems. First included in Windows Me, it has been included in all following desktop versions of Windows released since, excluding Windows Server. In Windows 10, System Restore is turned off by default and must be enabled by users in order to function. This does not affect personal files such as documents, music, pictures, and videos. In prior Windows versions it was based on a file filter that watched changes for a certain set of file extensions, and then copied files before they were overwritten. An updated version of System Restore introduced by Windows Vista uses the Shadow Copy service as a backend (allowing block-level changes in files located in any directory on the volume to be monitore ...

Snapshot (computer Storage)
In computer systems, a snapshot is the state of a system at a particular point in time. The term was coined as an analogy to that in photography. It can refer to an actual copy of the state of a system or to a capability provided by certain systems. Rationale A full backup of a large data set may take a long time to complete. On multi-tasking or multi-user systems, there may be writes to that data while it is being backed up. This prevents the backup from being atomic and introduces a version skew that may result in data corruption. For example, if a user moves a file into a directory that has already been backed up, then that file would be completely missing on the backup media, since the backup operation had already taken place before the addition of the file. Version skew may also cause corruption with files which change their size or contents underfoot while being read. One approach to safely backing up live data is to temporarily disable write access to data during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomicity (database Systems)
In database systems, atomicity (; from grc, ἄτομος, átomos, undividable) is one of the ACID (''Atomicity, Consistency, Isolation, Durability'') transaction properties. An atomic transaction is an ''indivisible'' and ''irreducible'' series of database operations such that either ''all'' occurs, or ''nothing'' occurs. A guarantee of atomicity prevents updates to the database occurring only partially, which can cause greater problems than rejecting the whole series outright. As a consequence, the transaction cannot be observed to be in progress by another database client. At one moment in time, it has not yet happened, and at the next it has already occurred in whole (or nothing happened if the transaction was cancelled in progress). An example of an atomic transaction is a monetary transfer from bank account A to account B. It consists of two operations, withdrawing the money from account A and saving it to account B. Performing these operations in an atomic transaction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OSTree
libostree (previously OSTree) is a system for versioning updates of Linux-based operating systems. It can be considered as "Git for operating system binaries". It operates in userspace, and will work on top of any Linux file system. At its core is a Git-like content-addressed object store with branches (or "refs") to track meaningful file system trees within the store. Similarly, one can check out or commit to these branches. Layered on top of that is bootloader configuration, management of /etc, and other functions to perform an upgrade beyond just replicating files. It is used by endless OS, Flatpak, Fedora, CentOS CentOS (, from Community Enterprise Operating System; also known as CentOS Linux) is a Linux distribution that provides a free and open-source community-supported computing platform, functionally compatible with its upstream source, Red Hat En ..., Atomic Host, and the GNOME continuous project for continuous delivery of GNOME components.

Brick (electronics)
A brick (or bricked device) is a mobile device, game console A video game console is an electronic device that outputs a video signal or image to display a video game that can be played with a game controller. These may be home consoles, which are generally placed in a permanent location connected to a t ..., router or other consumer electronics, consumer electronic device that is no longer functional due to corrupted firmware, a computer hardware, hardware problem, or other damage. The term analogy, analogizes the device to a brick's modern technological usefulness. Cause and prevention Bricking a device is most often a result of interrupting an attempt to software update, update the device. Many devices have an update procedure which must not be interrupted before completion; if interrupted by a power failure, user intervention, or any other reason, the existing firmware may be partially overwritten and unusable. The risk of corruption can be minimized by taking all possi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OtherOS
OtherOS is a feature of early versions of the PlayStation 3 video game console, allowing user installed software, such as Linux or FreeBSD. The feature was removed since system firmware update 3.21, released on April 1, 2010. Software running in the OtherOS environment has access to 6 of the 7 Synergistic Processing Elements. Sony implemented a hypervisor restricting access to the RSX. IBM provided an introduction to programming parallel applications on the PlayStation 3. After OtherOS was removed, a class action lawsuit was filed against Sony on behalf of users, but was dismissed with prejudice in 2011 by a federal judge. The judge stated: "As a legal matter, ... plaintiffs have failed to allege facts or articulate a theory on which Sony may be held liable." However, this decision was overturned in a 2014 appellate court decision finding that plaintiffs had indeed made clear and sufficiently substantial claims. Ultimately, in 2016, Sony settled with users who had installed Linux ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IPhone 7
The iPhone 7 and iPhone 7 Plus are smartphones that were designed, developed, and marketed by Apple Inc. They are the tenth generation of the iPhone.

Freeware
Freeware is software, most often proprietary, that is distributed at no monetary cost to the end user. There is no agreed-upon set of rights, license, or EULA that defines ''freeware'' unambiguously; every publisher defines its own rules for the freeware it offers. For instance, modification, redistribution by third parties, and reverse engineering are permitted by some publishers but prohibited by others. Unlike with free and open-source software, which are also often distributed free of charge, the source code for freeware is typically not made available. Freeware may be intended to benefit its producer by, for example, encouraging sales of a more capable version, as in the freemium and shareware business models. History The term ''freeware'' was coined in 1982 by Andrew Fluegelman, who wanted to sell PC-Talk, the communications application he had created, outside of commercial distribution channels. Fluegelman distributed the program via a process now termed '' shareware''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
