FSF - The Free Software Foundation (FSF) is a non-profit organization founded in October 1985 by Richard Stallman to support the free software movement (free as in freedom), and in particular the GNU project.

G
GPL - The GNU General Public License (GNU GPL or simply GPL) is the most popular free software license, originally written by Richard Stallman for the GNU project. The latest version of the license, version 2, was released in 1991. The GNU Lesser General Public License (LGPL) is a modified version of the GPL, intended for some software libraries.

GNU - Standing for GNU's not UNIX, this is a UNIX-compatible software system developed by the Free Software Foundation (FSF). Anyone can download, modify and redistribute GNU software. Linux systems rely heavily on GNU software and in the past, GNU systems used the Linux kernel. This close connection has led some people to mistakenly equate GNU with Linux. They are actually quite separate. In fact, the FSF is developing a new kernel called HURD to replace the Linux kernel in GNU systems.

H
HTML - Short for HyperText Markup Language, the authoring language used to create documents on the World Wide Web.

HTML is similar to SGML, although it is not a strict subset. HTML defines the structure and layout of a Web document by using a variety of tags and attributes.

L
LAN - A computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN).

Linux - a computer operating system and its kernel. It is one of the most prominent examples of free software and of open-source development: unlike proprietary operating systems such as Windows, all of its underlying source code is available to the public for anyone to freely use, modify, improve, and redistribute.
In the narrowest sense, the term Linux refers to the Linux kernel, but it is commonly used to describe entire Unix-like operating systems (also known as GNU/Linux) that are based on the Linux kernel combined with libraries and tools from the GNU Project and other sources. Most broadly, a Linux distribution bundles large quantities of application software with the core system, and provides more user-friendly installation and upgrades. Desktop environments such as GNOME and KDE are sometimes generically associated with Linux and are often referred to as such, but this is incorrect: a number of other operating systems, including FreeBSD use them.
