| LAN |
|
| A LAN is a
network of interconnected workstations sharing the resources of a single processor or
server within a relatively small geographic area. Typically, this might be within the area
of a small office building. However, FDDI extends a local area network over a much wider
area. Usually, the server has applications and data storage that are shared in common by
multiple workstation users. A local area network may serve as few as four or five users
or, in the case of FDDI, may serve several thousand. The main LAN technologies are:
Typically, a suite of application programs can be kept on the LAN server. Users who need an application frequently can download it once and then run it from their local hard disk. Users can order printing and other services as needed through applications run on the LAN server. A user can share files with others at the LAN server; read and write access is maintained by a LAN administrator. A LAN server may also be used as a Web server if safeguards are taken to secure internal applications and data from outside access.

| LapTop Computer |  |
| A laptop
computer, usually called a notebook computer by manufacturers, is a battery-powered
personal computer generally smaller than a briefcase that can easily be transported and
conveniently used in temporary spaces such as on airplanes, in libraries, temporary
offices, and at meetings. A laptop typically weighs less than 5 pounds and is 3 inches or
less in thickness. Among the best-known makers of laptop computers are IBM, NEC, Dell,
Toshiba, and Hewlett-Packard. Laptop computers generally cost more than desktop computers with the same capabilities because they are more difficult to design and manufacture. A laptop can effectively be turned into a desktop computer with a docking station, a hardware frame that supplies connections for peripheral input/output devices such as a printer or larger monitor. The less capable port replicator allows you to connect a laptop to a number of peripherals through a single plug. Laptops usually come with displays that use thin-screen technology. The TFT or active matrix screen is brighter and views better at different angles than the STN or dual-scan screen. Laptops use several different approaches for integrating a mouse into the keyboard, including the touch pad, the trackball, and the pointing stick. A serial port also allows a regular mouse to be attached. The PC Card is insertable hardware for adding a modem or network card to a laptop. CD-ROM and DVD drives may be built-in or attachable.

| LPT | |
| LPT (line
print terminal) is the usual designation for a parallel port connection to a printer or
other device on a personal computer. Most PCs come with one or two LPT connections
designated as LPT1 and LPT2. Some systems support a third, LPT3. Whatever the number, LPT1
is the usual default. You can add a parallel port for a second printer or other device by
buying and adding a parallel port adapter card to your computer. An LPT port can be used
for an input device such as QuickCam, a video camera used with CU-See-Me. Parallel computer connections traditionally have used the Centronics signalling interface for printer communication. A newer standard called EPP/ECP supports the older interface while providing faster communication for a range of devices, including scanners and video cameras.

| Linux
(often pronounced LIH-nuhks with a short
"i") is a UNIX-like operating system that was designed to provide personal
computer users a free or very low-cost operating system comparable to traditional and
usually more expensive UNIX systems. Linux has a reputation as a very efficient and
fast-performing system. Linux's kernel (the central part of the operating system) was
developed by Linus Torvalds at the University of Helsinki in Finland. To complete the
operating system, Torvalds and other team members made use of system components developed
by members of the Free Software Foundation for the GNU project. Linux is a remarkably complete operating system, including a graphical user interface, X Window System, TCP/IP, the Emacs editor, and other components usually found in a comprehensive UNIX system. Although copyrights are held by various creators of Linux's components, Linux is distributed using the Free Software Foundation's copyleft stipulations that mean any copy is in turn freely available to others. Unlike Windows and other proprietary systems, Linux is publicly open and extendible by contributors. Because it conforms to the POSIX standard user and programming interfaces, developers can write programs that can be ported to other operating systems, including IBM's OS/390 running UNIX. Linux comes in versions for all the major microprocessor platforms including the Intel, PowerPC, Sparc, and Alpha platforms. Linux is distributed commercially by a number of companies. A magazine, Linux Journal, is published as well as a number of books and pocket references. Linux is sometimes suggested as a possible publicly-developed alternative to the desktop predominance of Microsoft Windows. Although Linux is popular among users already familiar with UNIX, it remains far behind Windows in numbers of users.

| From the Linux Journal, here is Linus Torvalds' picture. | |
| Other popular sources for the Linux code are RedHat, Debian, MkLinux (for the Power Macintosh), and Caldera. | |
| You can download Linux directly. Or you can purchase it on CD-ROM from SSC, the Linux Journal publishers, by sending them an e-mail note. SSC also provides a help page. | |
| Linux Online! is a good starting place and notifies you about updates to the site. | |
| According to the Linux on the Web site, Linux running on
a 486 PC compares favorably with systems that run on mid-range workstations from Sun and
Digital.
