The Letter J
An object oriented programming language similar to C++, developed by Sun MicroSystems and used in the creation of network-based applications.
An input device used in computer gaming, primarily for games that utilize flight simulation. May also be used with other games, though less commonly. Older versions connected through a serial port. Modern Joysticks are USB based.
A plastic covered metal clip that sets over two pins on a circuit board. Jumpers connect pins, completing an electric circuit that changes configurations on devices, or can be used to kick start a switch.

The Letter K
The core component of an operating system. Provides the basic architecture that the system is built upon.
A series of keystrokes that are automatically input when a single key is pressed. Used often in Office application delivery for improved speed of performance and in PC gaming to take the place of laborious, systematic keystroke sequences.
A unit of storage equal to 1,024 bytes.

The Letter L
Stands for level one cache. A memory cache that is built into the CPU core to temporarily hold data being processed.
Stands for level two cache. A memory cache housed outside the processor core, but still a part of the CPU. Typically larger and slower than the L1 cache.
A computer system that is smaller than a briefcase but larger than a notebook. Typically has a clamshell design where the keyboard and display are on separate halves of the system. Named for its use as a computer that can be used while resting in the users lap.
A type of printer that is a combination of an electro-static copying machine and a printer. An electro-static charge is used to transfer toner onto the page, which is then fused onto the paper due to very high heat. As a result, pages are expelled from the printer very quickly and output in a completely dry state. Laser printers are fast, accurate, and don't require as much resupplying of printing media as Inkjet's do. They are, however, much more expensive.
LCD - Liquid Crystal Display
A display that uses liquid crystal sealed between two pieces of glass. Must be coupled with a back-light in order to display images. Quickly replacing CRTs as the computer display standard. Offer high resolution and true colors in a compact design.
LED - Light-Emitting Diode
A semiconductor diode that emits light when a current is passed through it.
Local Area Network
The connection of multiple computers using a network adapter card, and often a hub, switch, or router.
