Disk Image
A disk image, in computing, is a computer file containing the contents and structure of a disk volume or of an entire data storage device, such as a hard disk drive, tape drive, floppy disk, optical disc, or USB flash drive. A disk image is usually made by creating a sector-by-sector copy of the source medium, thereby perfectly replicating the structure and contents of a storage device independent of the file system. Depending on the disk image format, a disk image may span one or more computer files. The file format may be an open standard, such as the ISO image format for optical disc images, or a disk image may be unique to a particular software application. The size of a disk image can be large because it contains the contents of an entire disk. To reduce storage requirements, if an imaging utility is filesystem-aware it can omit copying unused space, and it can compress the used space. History Disk images were originally (in the late 1960s) used for backup and disk c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Administration Software
In computing, the term remote desktop refers to a software- or operating system feature that allows a personal computer's desktop environment to be run remotely off of one system (usually a PC, but the concept applies equally to a server or a smartphone), while being displayed on a separate client device. Remote desktop applications have varying features. Some allow attaching to an existing user's session and "remote controlling", either displaying the remote control session or blanking the screen. Taking over a desktop remotely is a form of remote administration. Overview Remote access can also be explained as the remote control of a computer by using another device connected via the internet or another network. This is widely used by many computer manufacturers and large businesses help desks for technical troubleshooting of their customer's problems. Remote desktop software captures the mouse and keyboard inputs from the local computer (client) and sends them to the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Hat Software
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the ...

Software Release Life Cycle
A software release life cycle is the sum of the stages of development and maturity for a piece of computer software ranging from its initial development to its eventual release, and including updated versions of the released version to help improve the software or fix software bugs still present in the software. There are several models for such a life cycle. A common method is that suggested by Microsoft, which divides software development into five phases: Pre-alpha, Alpha, Beta, Release candidate, and Stable. Pre-alpha refers to all activities performed during the software project before formal testing. The alpha phase generally begins when the software is feature complete but likely to contain several known or unknown bugs. The beta phase generally begins when the software is deemed feature complete, yet likely to contain several known or unknown bugs. Software in the production phase will generally have many more bugs in it than completed software, as well as speed/performa ...

End-of-life (product)
An end-of-life product (EOL product) is a product at the end of the product lifecycle which prevents users from receiving updates, indicating that the product is at the end of its useful life (from the vendor's point of view). At this stage, a vendor stops the marketing, selling, or provisioning of parts, services, or software updates for the product. The vendor may simply intend to limit or end support for the product. In the specific case of product sales, a vendor may employ the more specific term "end-of-sale" ("EOS"). All users can continue to access discontinued products, but cannot receive security updates and technical support. The time-frame after the last production date depends on the product and relates to the expected product lifetime from a customer's point of view. Different lifetime examples include toys from fast food chains (weeks or months), mobile phones (3 years) and cars (10 years). Product support Product support during EOL varies by product.

Good Faith
In human interactions, good faith ( la, bona fides) is a sincere intention to be fair, open, and honest, regardless of the outcome of the interaction. Some Latin phrases have lost their literal meaning over centuries, but that is not the case with ''bona fides'', which is still widely used and interchangeable with its generally-accepted modern-day English translation of ''good faith''. It is an important concept within law and business. The opposed concepts are bad faith, ''mala fides'' (duplicity) and perfidy (pretense). In contemporary English, the usage of ''bona fides'' is synonymous with credentials and identity. The phrase is sometimes used in job advertisements, and should not be confused with the ''bona fide'' occupational qualifications or the employer's good faith effort, as described below. ''Bona fides'' ''Bona fides'' is a Latin phrase meaning "good faith". Its ablative case is ''bona fide'', meaning "in good faith", which is often used as an adjective to ...

Ansible (software)
Ansible is a suite of software tools that enables infrastructure as code. It is open-source and the suite includes software provisioning, configuration management, and application deployment functionality. Originally written by Michael DeHaan and acquired by Red Hat in 2015, Ansible is designed to configure both Unix-like systems and Microsoft Windows. Ansible is agentless, relying on temporary remote connections via SSH or Windows Remote Management which allows PowerShell execution. The Ansible control node runs on most Unix-like systems that are able to run Python, including Windows with Windows Subsystem for Linux installed. System configuration is defined in part by using its own declarative language. History The term "ansible" was coined by Ursula K. Le Guin in her 1966 novel ''Rocannon's World'', and refers to fictional instantaneous communication systems. The Ansible tool was developed by Michael DeHaan, the author of the provisioning server application Cobbl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preboot Execution Environment
In computing, the Preboot eXecution Environment, PXE (most often pronounced as ''pixie'', often called PXE Boot/''pixie boot''.) specification describes a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP. The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and it forms part of the Unified Extensible Firmware Interface (UEFI) standard. In modern data centers, PXE is the most frequent choice for operating system booting, installation and deployment. Overview Since the beginning of computer networks, there has been a persistent need for client systems which can boot appropriate software images, with appropriate configuration parameters, both retrieved at boot time from one or more network se ...
