Kernel: Today’s operating systems are built in "layers". Each layer has different functions such as serial port access, disk access, and the user interface itself. The base layer, or the foundation of the operating system, is called a kernel. The kernel provides low-level services, such as the hardware-software interaction and memory management.

Link: When you’re browsing the Web and you see a highlighted and underlined word or phrase on a page, there’s a good chance you’re looking at a link. These links allow you to "jump" to another Web site, another frame, or another part of the page you’re currently viewing.

JavaScript: A script language (with little in common with Java) developed by Netscape for writing short programs embedded in a Web page. Netscape supports it from version 2.0 on and Microsoft and AOL browsers from version 4.0. MSIE 3.0 partially supports some features of JavaScript.

High Performance Addressing (HPA): This is a form of passive matrix LCD display that improves the response time of the display. HPA screens still suffer from the same contrast problems that make passive matrix inferior to active matrix TFT LCD screens.

Router: A router connects networks together, controlling the routing of packets from source to destination and providing alternate paths when necessary. Routers are more sophisticated than bridges, connecting networks of different types (for example, star and token ring), and making logical routing decisions on the basis of available data. Typically a router hands off packets to another router along the path until the destination is reached.

Honeypot: This is a system left open and unprotected to entice hackers to break into it. Usually this is done so that system administrators can monitor the system and the methods used to break in.
