The process whereby each user must login with a valid username and password before getting access to the user interface of a system.

An experimental Linux file system that contains advanced features such as storage pools and filesystem snapshots.

Also known as the Bourne Again Shell, this is the default command-line interface in Linux.

The part of a computer system that contains the programs used to initialize hardware components at boot time.

A program that exists on the file system and is executed when typed on the command line.

A nonjournaling Linux Filesystem.

A journaling Linux filesystem.

An improved version of the ext3 filesystem, with an extended future set and better performance.

A partition on a hard desk or SSD that can be further subdivided into components called logical drives.

The way in which a hard disk or SSD that can be further subdivided into components called logical drives.

The area of a large hard disk (> 2 TB) outside a partition that stores partition information boot loaders.

A list of hardware components that have been tested and deemed compatible with a given operating system.

A set of local, easy to read command syntax documentation available by typing the info commandline utility.

A file that contains the content of a DVD. ISO images of Linux installation media can be downloaded from the Internet.

A filesystem function that keeps track of information that needs to be written to the hard disk or SSD in a journal; common Linux journaling filesystems include ext3, ext4, and REISER.

Linux installation media that provides a fully functioning Linux operating system in RAM prior to installation on permanent storage.

The smaller partitions contained within an extended partition on a hard disk.

A set of services that are used to manage logical volumes stored on one or more hard disks.

The most common set of local command syntax documentation, available by typing the man commandline utility. Also known as man pages.

The area of a typical hard disk (< 2 TB) outside a partition that stores partition information boot loaders.

A common RAM-checking utility.

The key combinations that have special meaning in the Linux operating system.

The specific letters that start with a dash or two and appear after the command name to alter the way the command works.

A legacy hard disk technology that uses ribbon cables to typically attach up to four hard disk devices to a single computer.

A section of a hard disk or SSD. Partitions can be primary or extended.

The separate divisions into which a hard disk or SSD can be divided.

A type of storage that can be used to combine hard disks together to for performance and/or fault tolerance.

A journaling filesystem used in Linux.

A technology that allows for fast data transfer along a serial cable for hard disks and SSDs. It is commonly use the newer workstation and server-class computers.

A user interface that accepts input from the user and passes the input to the kernel for processing.

A high-performance hard disk technology that is commonly used in server class computers.

A type of disk drive that functions within a computer like a hard disk drive but instead uses fast flash memory chips to store data.

The channel that allows a certain user to login and communicate with the kernel via a user interface.

A non-journaling filesystem that might be used in Linux.

An operating system that is running within virtualization software.

An operating system that runs virtualization software.

An area on a hard disk or SSD that can be used to store information that normally resides in physical memory (RAM), if the physical memories being use excessively.

A set of programs that can be used to run an operating system within existing operating system concurrently.
