The FOG Project (named after Free and Open-source Ghost), is a suite of software tools for deploying disk images of Microsoft Windows and Linux using the Preboot Execution Environment (PXE). It makes use of TFTP , the Apache webserver and iPXE .
By default, read requests have an expiration time of 500ms, and write requests expire in 5 seconds. A rough version of the scheduler was published on the Linux Kernel Mailing List by Axboe in January 2002. [2] Measurements have shown that the deadline I/O scheduler outperforms the CFQ I/O scheduler for certain multi-threaded workloads. [3]
GHOST could clone a disk or partition to another disk or partition or to an image file. GHOST allows for writing a clone or image to a second disk in the same machine, another machine linked by a parallel or network cable, a network drive, or to a tape drive. 3.1 uses 286 with XMS and could still run on OS/2. [7]
A bootable device can be storage devices like floppy disk, CD-ROM, USB flash drive, a partition on a hard disk (where a hard disk stores multiple OS, e.g Windows and Fedora), a storage device on local network, etc. [7] A hard disk to boot Linux stores the Master Boot Record (MBR), which contains the first-stage/primary bootloader in order to be ...
The location of I/O schedulers in a simplified structure of the Linux kernel. The NOOP scheduler is the simplest I/O scheduler for the Linux kernel . This scheduler was developed by Jens Axboe .
Location of the "O(1) scheduler" (a process scheduler) in a simplified structure of the Linux kernel. An O(1) scheduler (pronounced "O of 1 scheduler", "Big O of 1 scheduler", or "constant time scheduler") is a kernel scheduling design that can schedule processes within a constant amount of time, regardless of how many processes are running on the operating system.
Darik's Boot and Nuke, also known as DBAN / ˈ d iː b æ n /, is a free and open-source project hosted on SourceForge. [2] The program is designed to securely erase a hard disk until its data is permanently removed and no longer recoverable, which is achieved by overwriting the data with pseudorandom numbers generated by Mersenne Twister or ISAAC.
Software that requires real-time input - Since all input at a thin client is sent over the network before it is registered by the operating system, there can be substantial delay. This is a major problem in software that requires real-time input (i.e. video games). Diskless nodes run the software locally, and as such, do not have this problem.
