Losetup
In Unix-like operating systems, a loop device, vnd (vnode disk), or lofi (loop file interface) is a pseudo-device that makes a computer file accessible as a block device. Before use, a loop device must be connected to an existent file in the file system. The association provides the user with an application programming interface (API) that allows the file to be used in place of a block special file (cf. device file system). Thus, if the file contains an entire file system, the file may then be mounted as if it were a disk device. Files of this kind are often used for CD ISO images and floppy disk images. Mounting a file containing a file system via such a loop mount makes the files within that file system accessible. They appear in the mount point directory. A loop device may allow some kind of data elaboration during this redirection. For example, the device may be the unencrypted version of an encrypted file. In such a case, the file associated with a loop device may be anoth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix-like
A Unix-like (sometimes referred to as UN*X, *nix or *NIX) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like Application software, application is one that behaves like the corresponding List of POSIX commands, Unix command or Unix shell, shell. Although there are general Unix philosophy, philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux, FreeBSD and OpenBSD. These systems are often used on servers as well as on personal computers and other devices. Many popular applications, such as the Apache HTTP Server, Apache web server and the Bash (Unix shell), Bash shell, are also designed to be used on Unix-like systems. Definition The Open ...

FreeBSD
FreeBSD is a free-software Unix-like operating system descended from the Berkeley Software Distribution (BSD). The first version was released in 1993 developed from 386BSD, one of the first fully functional and free Unix clones on affordable home-class hardware, and has since continuously been the most commonly used BSD-derived operating system. FreeBSD maintains a complete system, delivering a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties such as GNU for system software. The FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The project includes a security team overseeing all software shipped in the base distribution. Third-party applications may be installed using the pkg package management system or from source via FreeBSD Ports. The project is supported and promoted by the FreeBSD Foundation ...

Superuser
In computing, the superuser is a special user account used for system administration. Depending on the operating system (OS), the actual name of this account might be root, administrator, admin or supervisor. In some cases, the actual name of the account is not the determining factor; on Unix-like systems, for example, the user with a user identifier (UID) of zero is the superuser .e., uid=0 regardless of the name of that account; and in systems which implement a r model, any user with the role of superuser (or its synonyms) can carry out all actions of the superuser account. The principle of least privilege recommends that most users and applications run under an ordinary account to perform their work, as a superuser account is capable of making unrestricted, potentially adverse, system-wide changes. Unix and Unix-like In Unix-like computer OSes (such as Linux), ''root'' is the conventional name of the user who has all rights or permissions (to all files and programs) in all mod ...

Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

A2 (operating System)
A2 (formerly named Active Object System (AOS), and then Bluebottle) is a modular, object-oriented operating system with features including automatic garbage-collected memory management, and a zooming user interface. It was developed originally at ETH Zurich in 2002. It is free and open-source software under a BSD-like license. History A2 is a successor to Native Oberon, the x86 PC version of Niklaus Wirth's operating system Oberon. Out of printElectronic reprint./ref> It supports multiprocessing computers, and provides soft real-time computing operation. It is entirely written in Active Oberon. User interface Bluebottle replaced the older Oberon OS's unique text-based user interface (TUI) with a zooming user interface (ZUI), which similar to a conventional graphical user interface (GUI). Like Oberon, though, its user interface supports a ''point and click'' interface metaphor to execute commands directly from text, similar to clicking hyperlinks in a web browser. F ...

Alcohol 120%
Alcohol 120% is a disk image emulator and disc burning software for Microsoft Windows developed by Alcohol Soft. An edition named Alcohol 52% is also offered which lacks the burning engine. The software can create image files from a source CD/ DVD/Blu-ray, as well as mount them in virtual drives, all in the proprietary Media Descriptor File format; images in this format consist of a pair of .mds and .mdf files. Features Alcohol 120%'s image recording feature is capable of bypassing certain copy protection schemes, such as SafeDisc, SecuROM, and Data Position Measurement (DPM). However, certain copy protection schemes require burner hardware that is capable of reproducing the copy protection. It can also create images of PlayStation and PlayStation 2 file systems. It lacks the ability to back up DVD titles encrypted with the Content Scramble System. Due to legal restrictions, Alcohol Soft has opted not to include this feature. Some software manufacturers employ software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diskpart
In computing, diskpart is a command-line interface, command-line disk partitioning utility included in Windows 2000 and later Microsoft operating systems, replacing its predecessor, fdisk. The command is also available in ReactOS. Overview The diskpart utility is used for partitioning internal hard drives but can also format removable media such as flash drives. It has long been possible, theoretically, to partition removable drives – such as flash drives or memory cards – from within Windows NT 4.0 / 2000 / XP; e.g., during system installation. In reality, however, it was not possible to create, for instance, a recovery console, for such a device. A message would appear: 'Cannot format removable disk'. Microsoft noticed this error and responded by disabling the functionalities of creating and viewing partitions on the device from within Windows, beginning with Vista up to Windows 10. With diskpart, scripts are supported to facilitate such functions. For example, the cod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
