| Local Area Network (LAN) |
| A local area network is a short-distance system used to link a group of computers together. The most commonly used form of LAN is the 10BaseT Ethernet. A piece of hardware called a hub serves as the common wiring point, enabling data to be sent from one machine to another over the network. LANs are typically limited to distances of less than 500 meters and provide low-cost, high-bandwidth networking capabilities within a small geographic area. |
| Linux |
| What do you do if you're not happy with the computer operating systems on the market? You build your own, of course. That's exactly what Linus Torvalds did. He created an open-source operating system: "open source" meaning that it's available to all (unlike proprietary systems tied to individual brands) and "operating system" meaning the computer's fundamental programming. His freely distributed, Intel-processor-based system is now used around the world. While Linux (pronounced LIH-nucks) began life primarily as a hobby for supergeeks, it has made inroads into corporate life, particularly as an inexpensive substitute for high-priced Unix operating system-based Web servers. Linux is available from a number of vendors for several hardware platforms, including Intel x86, DEC Alpha, Sun Sparc, and Motorola PowerPC. It is compatible with Windows. |
| Megabyte (M or MB) |
| A unit of measure for a chunk of data totaling about 1 million bytes (1,048,576 bytes, or 2 to the 20th power, to be exact, because bytes are calculated as binary numbers, based on the number 2). The following table shows standard measures of data based on bytes:

| Malware |
| Malware is a kind of software program whose name derives from the words "malicious" and "software" -- and that is just what it is. Malware is typically transmitted via the Internet or a computer network, and can damage or destroy the infected computer or network. Malware comes in several forms: viruses, worms, zombies, Trojan Horses, and spyware. Each form is engineered differently, but all are destructive. Software is available to protect against malware. |
| Megabits Per Second (Mbps) |
| A unit of measure that tells how many megabits of data can be transferred from one computer to another in a second (a bit being the smallest unit of data and megabit being about 1 million bits). Typically used to measure the rate at which information travels over the Internet. |
| Multi-purpose Internet Mail Extensions (MIME) |
| MIME has absolutely nothing to do with Marcel Marceau. It's a way to extend the power of the Web to handle graphics, sound, multimedia, and non-text (non-HTML-based) data, or in the case of email, to handle text that is based on the ASCII computer language. |
| Moving Pictures Experts Group (MPEG) |
| MPEG is a standard for compressing sound and movie files into a format for downloading -- or even streaming it live -- across the Internet. It is one of three major video technologies for computing. (The others are Video for Windows and QuickTime.) There are three versions of MPEG. MPEG-1 moves video and sound data at 150 kilobytes per second (the same rate as a single-speed CD-ROM drive), which it manages by taking key frames of video and filling only the areas that change between the frames. But MPEG-1 produces only adequate-quality video, far below that of standard TV. MPEG-2 compression improves things dramatically, providing near-laserdisc clarity with a CD-quality stereo soundtrack. For that reason, modern video delivery media, such as digital satellite services and DVD, use MPEG-2. MPEG-4 combines the technology of the other two with that of QuickTime and uses narrower bandwith. |
| News Reader |
| A software program that connects you to the interactive online discussion group known as a newsgroup.
|
| Newsgroup |
| An interactive online discussion group, also called a forum. Think of newsgroups as worldwide bulletin boards, organized more or less stringently around a particular topic. They use the Network News Transfer Protocol technology. You need a news reader software program, such as Outlook Express and Forte FreeAgent, to view the discussion and add your comments. |
| Open Proxy, Open Proxy Server |
| A proxy server is a kind of server (a computer that delivers or "serves" information to other computers). The proxy links the user (often the Web browser on your personal computer, or a computer in a network or group) and another main server. The proxy can store information, so that if more than one user requests the same data, it delivers it, eliminating the need to tie up the main server with duplicated requests. The proxy can also filter transmissions, and is often used in workplace networks to screen out unwanted communications. An open proxy will accept connections from any network address, acting as a blind intermediary to virtually anybody. On the Internet, an open proxy can allow various kinds of malware (viruses, etc.) to be transmitted. |
