A Linux distribution is an operating system made from a software collection that is based upon the Linux kernel and, often, a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices and personal computers to powerful supercomputers.
KNOPPIX is an operating system based on Debian designed to be run directly from a CD / DVD or a USB flash drive, one of the first of its kind for any operating system. Knoppix was developed by, and named after, Linux consultant Klaus Knopper. When starting a program, it is loaded from the removable medium and decompressed into a RAM drive. The decompression is transparent and on-the-fly.
A live CD is a complete bootable computer installation including operating system which runs directly from a CD-ROM or similar storage device into a computer's memory, rather than loading from a hard disk drive. A live CD allows users to run an operating system for any purpose without installing it or making any changes to the computer's configuration. Live CDs can run on a computer without secondary storage, such as a hard disk drive, or with a corrupted hard disk drive or file system, allowing data recovery.
dyne:bolic GNU/Linux is a Live CD/DVD distribution based on the Linux kernel. It is shaped by the needs of media activists, artists and creators to be a practical tool with a focus on multimedia production, that delivers a large assortment of applications. It allows manipulation and broadcast of both sound and video with tools to record, edit, encode, and stream. In addition to multimedia specific programs, dyne:bolic also provides word processors and common desktop computing tools.
A bootable business card (BBC) is a CD-ROM that has been cut, pressed, or molded to the size and shape of a business card. Alternative names for this form factor include "credit card," "hockey rink," and "wallet-size". The cards are designed to hold about 50 MB. The CD-ROM business cards are generally used for commercial product demos, are mailed to prospective customers, and are given away at trade shows.
Kanotix, also referred to as KANOTIX, is an operating system based on Debian, with advanced hardware detection. It can run from an optical disc drive or other media i.e. USB-stick without using a hard disk drive.
Berry Linux is a Live CD Linux distribution that has English and Japanese support. Berry Linux is based on and is compatible with Fedora 20 packages. The distribution is primarily focused on use as a Live CD, but it can also be installed to a live USB drive. Berry Linux can be used to try out and showcase Linux, for educational purposes, or as a rescue system, without the need to make changes to a hard disk. The current version is 1.35 released on 7 July 2021.
Disk cloning is the process of creating a 1-to-1 copy of a hard disk drive (HDD) or solid-state drive (SSD), not just its files. Disk cloning may be used for upgrading a disk or replacing an aging disk with a fresh one. In this case, the clone can replace the original disk in its host computer. Disk cloning may also be used for disaster recovery or forensics. In the context of backup software, disk cloning is very similar to disk imaging; in case of the latter, a 1-to-1 copy of a disk is created inside a disk image file.
Puppy Linux is an operating system and family of light-weight Linux distributions that focus on ease of use and minimal memory footprint. The entire system can be run from random-access memory with current versions generally taking up about 600 MB (64-bit), 300 MB (32-bit), allowing the boot medium to be removed after the operating system has started. Applications such as AbiWord, Gnumeric and MPlayer are included, along with a choice of lightweight web browsers and a utility for downloading other packages. The distribution was originally developed by Barry Kauler and other members of the community, until Kauler retired in 2013. The tool Woof can build a Puppy Linux distribution from the binary packages of other Linux distributions.
GParted is a GTK front-end to GNU Parted and an official GNOME partition-editing application. GParted is used for creating, deleting, resizing, moving, checking, and copying 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.
In Linux systems, initrd is a scheme for loading a temporary root file system into memory, to be used as part of the Linux startup process. initrd and initramfs refer to two different methods of achieving this. Both are commonly used to make preparations before the real root file system can be mounted.
A live USB is a portable USB-attached external data storage device containing a full operating system that can be booted from. The term is reminiscent of USB flash drives but may encompass an external hard disk drive or solid-state drive, though they may be referred to as "live HDD" and "live SSD" respectively. They are the evolutionary next step after live CDs, but with the added benefit of writable storage, allowing customizations to the booted operating system. Live USBs can be used in embedded systems for system administration, data recovery, or test driving, and can persistently save settings and install software packages on the USB device.
Software remastering is software development that recreates system software and applications while incorporating customizations, with the intent that it is copied and run elsewhere for "off-label" usage. The term comes from remastering in media production, where it is similarly distinguished from mere copying.
Ubuntu Studio is a recognized flavor of the Ubuntu Linux distribution, which is geared to general multimedia production. The original version, based on Ubuntu 7.04, was released on 10 May 2007.
UNetbootin is a cross-platform utility that can create live USB systems and can load a variety of system utilities or install various Linux distributions and other operating systems without a CD.
This is a partial comparison list of disk cloning software, computer programs that can copy the contents of one disk into another disk or into a disk image.
Clonezilla is a suite of open source drive cloning, drive imaging and system deployment utilities used to simpify deployment and maintenance of a group of computers. CloneZilla Server Edition uses multicast technologies to deploy a single image file to a group of computers on a local area network. Clonezilla was designed by Steven Shiau and developed by the NCHC Free Software Labs in Taiwan.
NimbleX is a small Slackware-based Linux distribution optimized to run from a CD, USB drive or a network environment. NimbleX has been praised for how fast it boots, as well as for its small disk footprint, which is considered surprising for a distribution using KDE as desktop environment. NimbleX was also remarked for its web site that allows users to generate custom bootable images using just a web browser. It was also covered in mainstream Romanian press as the first Linux distribution put together by a Romanian.
Netbooks are small laptops, with screen sizes between approximately 7 and 12 inches and low power consumption. They use either an SSD or a HDD for storage, have up to 2 gigabytes of RAM, lack an optical disk drive, and usually have USB, Ethernet, WiFi and often Bluetooth connectivity. The name emphasizes their use as portable Internet appliances.
