Graphical user interface (GUI) - ANSWER-A method of human-computer interaction characterized by a
graphical display, a mouse to move a pointer around the screen, and the ability to perform actions by
pointing at objects on the screen and clicking a mouse button.
kernel - ANSWER-The core of an operating system, which provides multitasking (process creation,
interprocess protection, interprocess communication), memory management, and basic I/O
management.
X server - ANSWER-A program that implements X for a computer; especially the component that
interacts most directly with the video hardware.
X.org-X11 - ANSWER-In 2004, most Linux distributions shifted from XFree86 to _____ because of
licensing changes to XFree86. _____ 6.7.0 was based on XFree86 4.3.99, but it's developed
independently up to the current version, 7.7. Because _____ is based on XFree86, the two are virtually
identical in most important respects. One significant difference is the name of the configuration file;
another is the default location for fonts.
TiVo - ANSWER-A popular digital video recorder (DVR) that uses a Linux kernel and a significant number
of standard support programs, along with proprietary drivers and DVR software.
Binaries - ANSWER-Program files that are created by programmers for a particular processor and
kernel—for each OS.
libc - ANSWER-A library of standard functions that are used by all C programs.
UNetbootin - ANSWER-A tool that can copy the files from a Linux installation disc image file to a USB
flash drive.
,Parted Magic - ANSWER-A Linux distribution for PCs that's intended for emergency recovery operations.
Zettabyte File System (ZFS) - ANSWER-A filesystem designed to ensure that data stored on disks cannot
be lost due to any physical error or misprocessing by the hardware or operating system.
Free software - ANSWER-Software that is distributed under a license, such as the GPL, that permits
copying and modification under liberal terms. See also open source.
General Public License (GPL) - ANSWER-A common free software license, created and favored by the
Free Software Foundation.
Open source - ANSWER-A broad set of software licenses, or the software that uses them, that permits
redistribution and copying under liberal terms. The open source definition is somewhat broader than
that of free software.
BSD - ANSWER-A license used by the open source BSD OSs and by various software components
developed for them. It allows modifications to be distributed under other licenses.
GNU Free Documentation License (FDL) - ANSWER-A license that is intended for use in documentation
rather than by programs.
Copyright - ANSWER-A legally recognized right to create a copy of something.
Apache - ANSWER-An open source license that permits redistribution under the same or another
license.
Bounties - ANSWER-A crowdfunding method through which users can drive open source creation by
offering to pay for new software or new features in existing software.
Copyleft - ANSWER-A license that gives the right to people to freely distribute copies and modified
versions of a work with the agreement.
, Software - ANSWER-A type of intellectual property that is governed by copyright laws and, in some
countries, patent laws.
Berkeley Internet Name Domain (BIND) - ANSWER-A common Domain Name System (DNS) server for
Linux.
Common Unix Printing System (CUPS) - ANSWER-A printing system for Linux and other Unix-like
systems. CUPS adds several features that had been missing from the earlier BSD, LPD, and LPRng
printing systems.
Network Time Protocol (NTP) - ANSWER-A network protocol and server enabling one computer to set its
clock based on the value maintained by another clock.
Samba - ANSWER-The standard Windows interoperability suite of programs for Linux and Unix.
Source code - ANSWER-The version of a program written by a human and typically stored in plaintext
(ASCII) file format. A compiler converts source code to a binary form that a computer can run.
Preemptive multitasking - ANSWER-A task in which the kernel schedules the CPU time for programs,
even if the programs didn't voluntarily give up control.
Cooperative multitasking - ANSWER-A task in which the programs could voluntarily give up CPU time to
other processes.
Shareware - ANSWER-A software similar to commercial software in that it's copyrighted and the author
asks for payment.
X Window System - ANSWER-A highly configurable and free client-server system that manages the
graphical user interfaces (GUIs) on a particular computer and on computers within a network.
Dynamic Host Configuration Protocol (DHCP) - ANSWER-A protocol that is controlled by the DHCP server
and it dynamically assigns the IP address to any device over a network for the purpose of
communication through IP.
