System Rescue CD
SystemRescue (Previously known as "SystemRescueCD") is a Linux distribution for x86-64 and IA-32 computers. The primary purpose of SystemRescue is to repair unbootable or otherwise damaged computer systems after a system crash. SystemRescue is not intended to be used as a permanent operating system. It runs from a Live CD, a USB flash drive or any type of hard drive. It was designed by a team led by François Dupoux, and is based on Arch Linux since version 6.0. Starting with version 6.0, it has systemd as its init system. Requirements For more recent versions, a 64-bit processor is required, with 32-bit processors being deprecated after version 9.03 in 2017. PowerPC had a single release with version 0.2.0 in 2004, with SPARC also having one for version 0.4.0 in 2007. If a PXE boot requires HTTP or TFTP, at least 1GB of memory will be needed for loading a required file for those into memory. However if NFS or NBD is used, the 1GB requirement isn't necessary.

Arch Linux
Arch Linux () is an Open-source software, open source, rolling release Linux distribution. Arch Linux is kept up-to-date by regularly updating the individual pieces of software that it comprises. Arch Linux is intentionally minimal, and is meant to be configured by the user during installation so they may add only what they require. Arch Linux provides monthly "snapshots" which are used as Optical disc image, installation media. #Pacman, Pacman, a package manager written specifically for Arch Linux, is used to install, remove and update software packages. Additionally, the Arch User Repository (AUR), which is the community-driven repository for Arch Linux provides packages not included in the official repositories and alternative versions of packages; AUR packages can be downloaded and built manually, or installed through an AUR 'helper'. Arch Linux has comprehensive documentation in the form of a community-run wiki known as the ArchWiki. History Inspired by CRUX, another mi ...

Modem
The Democratic Movement (, ; MoDem ) is a centre to centre-right political party in France, whose main ideological trends are liberalism and Christian democracy, and that is characterised by a strong pro-Europeanist stance. MoDem was established by François Bayrou to succeed the Union for French Democracy (UDF) and contest the 2007 legislative election, after his strong showing in the 2007 presidential election. Initially named the Democratic Party (''Parti démocrate''), the party was renamed "Democratic Movement", because there was already a small Democratic Party in France. MoDem secured an agreement with La République En Marche! (LRM) — later Renaissance (RE) — in the 2017 legislative election after Bayrou had endorsed the candidacy of Emmanuel Macron in February. The two parties have since been in alliance, as of late named Ensemble. The party's founder and leader Bayrou has served as Prime Minister of France since December 2024.

Asymmetric Digital Subscriber Line
Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL differs from the less common symmetric digital subscriber line (SDSL). In ADSL, bandwidth and bit rate are said to be asymmetric, meaning greater toward the customer premises ( downstream) than the reverse ( upstream). Providers usually market ADSL as an Internet access service primarily for downloading content from the Internet, but not for serving content accessed by others. Overview ADSL works by using spectrum above the band used by voice telephone calls. With a DSL filter, often called ''splitter'', the frequency bands are isolated, permitting a single telephone line to be used for both ADSL service and telephone calls at the same time. ADSL is generally only installed for short distances from the telephone exchange (the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GParted
GParted is a GTK front-end to GNU Parted and an official GNOME partition-editing application (alongside GNOME Disks, Disks). GParted is used for creating, deleting, resizing, moving, checking, and copying Partition (computing), disk partitions and their file systems. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks, and mirroring one partition with another (disk imaging). It can also be used to format a USB drive. Background GParted uses GNU Parted, libparted to detect and manipulate devices and partition tables while several (optional) file system tools provide support for file systems not included in libparted. These optional packages will be detected at runtime and do not require a rebuild of GParted. GParted supports the following filesystems: Ext2, Ext3, Ext4, FAT16, Fat32, FAT32, Hierarchical File System (Apple), HFS, HFS Plus, HFS+, JFS (file system), JFS, Linux swap, Linux-swap, ReiserFS, Reiser4, ...

Linux Framebuffer
The framebuffer subsystem in the Linux kernel fbdev is used to show graphics on a computer monitor, typically on the system console. It was designed as a hardware-independent API to give user space software access to the framebuffer (the part of a computer's video memory containing a current video frame) using only the Linux kernel's own basic facilities and its device file system interface, avoiding the need for libraries like SVGAlib which effectively implemented video drivers in user space. In most applications, fbdev has been superseded by the Linux Direct Rendering Manager (DRM) subsystem, but as of 2022, several drivers provide both DRM and fbdev APIs for backwards compatibility with software that has not been updated to use the DRM system, and there are still fbdev drivers for older (mostly embedded) hardware that does not have a DRM driver. Applications There are three applications of the Linux framebuffer: * An implementation of text Linux console that doesn't ...

Network Block Device
On Linux, network block device (NBD) is a network protocol that can be used to forward a device node, block device (typically a hard disk or partition) from one machine to a second machine. As an example, a local machine can access a hard disk drive that is attached to another computer. The protocol was originally developed for Linux 2.1.55 and released in 1997. In 2011 the protocol was revisedformally documented and is now developed as a collaborative open standard. There are several Interoperability, interoperable clients and servers. There are Linux-compatible NBD implementations for FreeBSD and other operating systems. The term 'network block device' is sometimes also used generically. Technically, a network block device is realized by three components: the server part, the client part, and the network between them. On the client machine, which uses the exported device node, a kernel driver implements a virtual device. Whenever a program tries to access the device, the ...

Network File System
Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, allowing a user on a client computer to access files over a computer network much like local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. NFS is an open IETF standard defined in a Request for Comments (RFC), allowing anyone to implement the protocol. Versions and variations Sun used version 1 only for in-house experimental purposes. When the development team added substantial changes to NFS version 1 and released it outside of Sun, they decided to release the new version as v2, so that version interoperation and RPC version fallback could be tested. NFSv2 Version 2 of the protocol (defined in , March 1989) originally operated only over User Datagram Protocol (UDP). Its designers meant to keep the server side stateless, with locking (for example) implement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trivial File Transfer Protocol
The Trivial File Transfer Protocol (TFTP) is a simple Lockstep (computing), lockstep communication protocol for transmitting or receiving files in a client-server application. A primary use of TFTP is in the early stages of nodes booting on a local area network when the operating system or firmware images are stored on a file server. TFTP was first standardized in 1981 and updated in . Overview Due to its simple design, TFTP can be easily implemented by code with a small memory footprint. It is, therefore, the protocol of choice for the initial stages of any network booting strategy like Bootstrap Protocol, BOOTP, Preboot Execution Environment, PXE, Boot Service Discovery Protocol, BSDP, etc., when targeting from highly resourced computers to very low resourced Single-board computers (SBC) and System-on-a-chip, System on a Chip (SoC). It is also used to transfer firmware images and configuration files to network appliances like Router (computing), routers, Firewall (computing) ...

HTTP
HTTP (Hypertext Transfer Protocol) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a Computer mouse, mouse click or by tapping the screen in a web browser. Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989 and summarized in a simple document describing the behavior of a client and a server using the first HTTP version, named 0.9. That version was subsequently developed, eventually becoming the public 1.0. Development of early HTTP Requests for Comments (RFCs) started a few years later in a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving to the IETF. HTTP/1 was finalized and fully documented (as version 1.0) in 1996 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preboot Execution Environment
In computing, the Preboot eXecution Environment (PXE; often pronounced as ''pixie''), often called PXE boot (''pixie boot''), is a specification describing 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 Dynamic Host Configuration Protocol (DHCP) and Trivial File Transfer Protocol (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 configu ...
