KDE

Stands for "K Desktop Environment." KDE is a contemporary desktop environment for Unix systems. It is a Free Software project developed by hundreds of software programmers across the world. Both the KDE source code and the software itself are made freely available to the public.
KDE's primary benefit is the modern graphical user interface GUI it provides for Unix workstations. While Unix systems are notoriously difficult for novice users to operate, KDE makes it possible for the average user to work on a Unix system

Kernel

To understand what a kernel is, you first need to know that today's operating systems are built in "layers." Each layer has different functions such as serial port access, disk access, memory management, and the user interface itself. The base layer, or the foundation of the operating system, is called the kernel. The kernel provides the most basic "low-level" services, such as the hardware-software interaction and memory management. The more efficient the kernel is, the more efficiently the operating system will ru

Horizontal Market Software

A horizontal market is one that supplies goods to a variety of industries instead of just one. Therefore, horizontal market software is software that can be used by several different types of industries.
For example, word processing and spreadsheet programs are horizontal market applications because they can be used by many types of businesses and consumers.

EPS

Stands for "Encapsulated PostScript." EPS is a PostScript image file format that is compatible with PostScript printers and is often used for transferring files between various graphics applications. EPS files will print identically on all PostScript-compatible printers and will appear the same in all applications that can read the PostScript format.

Source Code

Every computer program is written in a programming language, such as Java, C/C++, or Perl. These programs include anywhere from a few lines to millions of lines of text, called source code.
Source code, often referred to as simply the "source" of a program, contains variable declarations, instructions, functions, loops, and other statements that tell the program how to function. Programmers may also add comments to their source code that explain sections of the code. These comments help other programmers gain at least some idea of what the source code does without requiring hours to decipher it.

Open Source

When a software program is open source, it means the program's source code is freely available to the public. Unlike commercial software, open source programs can be modified and distributed by anyone and are often developed as a community rather than by a single organization. Since the source code of an open source program can be modified by anyone, it makes sense that the software is also free to download and use.

Firmware

Firmware is a software program or set of instructions programmed on a hardware device. It provides the necessary instructions for how the device communicates with the other computer hardware. Firmware is typically stored in the flash ROM of a hardware device
