The Linux kernel is a free and open-source, [12] : 4 monolithic, modular, multitasking, Unix-like operating system kernel. It was originally written in 1991 by Linus Torvalds for his i386 -based PC, and it was soon adopted as the kernel for the GNU operating system, which was written to be a free (libre) replacement for Unix .
File descriptor. In Unix and Unix-like computer operating systems, a file descriptor ( FD, less frequently fildes) is a process-unique identifier ( handle) for a file or other input/output resource, such as a pipe or network socket. File descriptors typically have non-negative integer values, with negative values being reserved to indicate "no ...
Hard link. In computing, a hard link is a directory entry (in a directory -based file system) that associates a name with a file. Thus, each file must have at least one hard link. Creating additional hard links for a file makes the contents of that file accessible via additional paths (i.e., via different names or in different directories). [1]
ext4 ( fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3 . ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance ...
The directory given to the operating system is called the mount point – it might, for example, be /media. The /media directory exists on many Unix systems (as specified in the Filesystem Hierarchy Standard) and is intended specifically for use as a mount point for removable media such as CDs, DVDs, USB drives or floppy disks. It may be empty ...
Optical discs. ISO 9660 (also known as ECMA -119) is a file system for optical disc media. The file system is an international standard available from the International Organization for Standardization (ISO). Since the specification is available for anybody to purchase, [1] implementations have been written for many operating systems .
Start downloading a Wikipedia database dump file such as an English Wikipedia dump. It is best to use a download manager such as GetRight so you can resume downloading the file even if your computer crashes or is shut down during the download. Download XAMPPLITE from [2] (you must get the 1.5.0 version for it to work).
The core data structure of Btrfs—the copy-on-write B-tree—was originally proposed by IBM researcher Ohad Rodeh at a presentation at USENIX 2007. Chris Mason, an engineer working on ReiserFS for SUSE at the time, joined Oracle later that year and began work on a new file system based on these B-trees.
