WGU C851 Linux Foundations Question
and answers already passed 2026
Graphical user interface (GUI) - correct 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 - correct 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 - correct answer A program that implements X for a computer; especially the component that
interacts most directly with the video hardware.
X.org-X11 - correct 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 - correct 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 - correct answer Program files that are created by programmers for a particular processor and
kernel—for each OS.
libc - correct answer A library of standard functions that are used by all C programs.
UNetbootin - correct answer A tool that can copy the files from a Linux installation disc image file to a
USB flash drive.
,Parted Magic - correct answer A Linux distribution for PCs that's intended for emergency recovery
operations.
Zettabyte File System (ZFS) - correct 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 - correct 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) - correct answer A common free software license, created and favored by
the Free Software Foundation.
Open source - correct 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 - correct 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) - correct answer A license that is intended for use in
documentation rather than by programs.
Copyright - correct answer A legally recognized right to create a copy of something.
Apache - correct answer An open source license that permits redistribution under the same or another
license.
, Bounties - correct 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 - correct answer A license that gives the right to people to freely distribute copies and modified
versions of a work with the agreement.
Software - correct answer A type of intellectual property that is governed by copyright laws and, in
some countries, patent laws.
Berkeley Internet Name Domain (BIND) - correct answer A common Domain Name System (DNS) server
for Linux.
Common Unix Printing System (CUPS) - correct 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) - correct answer A network protocol and server enabling one computer to
set its clock based on the value maintained by another clock.
Samba - correct answer The standard Windows interoperability suite of programs for Linux and Unix.
Source code - correct 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 - correct 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 - correct answer A task in which the programs could voluntarily give up CPU
time to other processes.
