LANanalyzer:-

A hardware/software combination product from Network Communications Corp. used to troubleshoot and monitor performance and activity on Ethernet and Token Ring local-area networks (LANs).

The LANalyzer hardware includes an on-board processor and a 2-megabyte buffer for packet capturing. The package can decode most of the LAN protocols in common use, including NetWare, TCP/IP, DECnet. Banyan, Network File System (NFS), Apple Talk Filing Protocol (AFP), Open Systems Interconnection (OSI), SNA (Systems Network Architecture), NetBEUI, Xerox Network Services (XNS), and SMB (Server Message Block).

LANDesk Manager:-

A package of network management utilities from Intel Corporation that includes hardware and software inventory, NetWare server monitoring, client monitoring and control, network traffic monitoring, virus protection, remove access, remote control, and print-queue management.

LAN Distance:-

A remote access software package from IBM that lets network users log in from their PC or portable computer when they are away from the office

LANLord:-

A package of network management utilities from Symantec Corporation that includes hardware and software inventory, client monitoring and control, traffic monitoring, application metering, and virus protection. This package also includes automatic task scheduling, alerting, and report generation.

LAN Manager:-

A network operating system, developed by Microsoft and 3Com that runs on 80386 and 80486 computers. The file-server software is a version of OS/2; client PCs can be OS/2, DOS, UNIX, or Macintosh, Disk mirroring, disk duplexing and UPS (uninterruptible power supply) monitoring functions are available. The network operating system supports IPX/ SPX, TCP/IP, and NetBEUI. The illustration on the following page shows the LAN Manager architecture.

LAN Server:-

An IBM network operating system, based on a version of OS/2, that runs on 80386 and later Intel processors, as well as on the PowerPC. LAN Server supports Microsoft Windows, DOS, OS/2, and Macintosh clients, and AppleTalk, IPX/SPX, TCP/IP, and NetBIOS protocols. LAN Server supports domain directory services and encrypted passwords, but does not include C-2 level certification.

Laplink:-

A popular communication package, from Travelling Software, used to transfer and synchronize files between a laptop computer and a desktop or networked computer.

Laptop Computer:-

A small, portable computer that is light enough to carry comfortably, with a flat screen and keyboard that fold together. Laptop computers are battery.-operated. Advances in battery technology allow laptop computers to run for many hours between charges. Laptop computers often have a thin, backlit or sidelid liquid-crystal display (LCD) screen. Some models can mate with a docking station to perform as a full-sized desktop system back at the office, and many new laptop computers allow direct connection to the network with PCMCIA network interface cards. In some laptop computers, a set of business applications are built into ROM (read-only memory).

Line Driver:-

In communications, a hardware device used to extend the transmission distance between computers that are connected using leased lines. A line is required at each end of the line for digital communications.

Line-sharing device:-

A small electronic device that allows a fax machine and a telephone answering machine to share the same phone line. The device answers the call and listens for the characteristic high-pitched fax carrier signal. If this signal is detected, the call is routed to the fax machine; if it is not present, the call is sent to a telephone or answering machine instead.

LIP:-

Abbreviation for Large Internet Packet. A mechanism that allows the Novell NetWare inter-network packet size to be increased from the default 576 bytes, thus increasing throughput over bridges and routers-liquid crystal display.

List server:-

Abbreviated listserv. An automatic mailing system on the Internet. Rather than sending e-mail on a particular topic to a long list of people, you send it instead to a special e-mail address, where a program automatically distributes the e-mail to all the people who subscribe to the mailing list. Several programs have been written to automate a mailing list; you may also encounter mailserv, majordomo, or almanac. Mailing lists are usually devoted to a specific subject, rather than to general interest communications.

Load Balancing:-

A technique that distributes network traffic along parallel paths to make the most efficient use of the available bandwidth while providing redundancy at the same time. Load balancing will automatically move a user's job from a heavily loaded network resource to a less loaded resource.

Local Bus:-

A PC bus specification that allows peripheral devices to exchange data at a rate faster than the 8 megabytes per second allowed by the ISA (Industry Standard Architecture) and the 32 megabytes per second allowed by the EISA (Extended Industry Standard Architecture) definition. Local bus can achieve a maximum data rate of 133 megabytes per second with a 33 MHz bus speed, 148 megabytes per second with a 40 MHz bus, or 267 megabytes per second with a 50 MHz bus. Local bus capability must be built into the system's mother board right from the start; it is not possible to convert an ISA-EISA-, or MCA-based computer into a local-bus system.

To date, the VESA (Video Electronics Standards Association) video cards have been the main peripheral to benefit from local bus use, although Intel's PCI (Peripheral Component Interconnect) local bus is gaining popularity.

Local Printer:-

In networking, a printer attached to a workstation rather than to the file server or a print server.

LocalTalk:-

The shielded, twisted pair (STP) wiring and connectors available from Apple for connecting Macintosh computers using the built-in AppleTalk network hardware.

Login script:-

A small file or macro that executes the same set of instructions every time a user logs in to a computer system or network. Login scripts can map drives, display messages, set environment variables, and run programs, and are critical for proper configuration of each user's network environment.

A communications script may send the user-identification information to an online information service each time a subscriber dials up the service.

Logout:-

A Novell NetWare utility used to log out of the network, or to disconnect from a specific server while remaining attached to all other connections.

Loop back:-

A troubleshooting test in which ^ signal is transmitted from a source to a destination and then back to the source again so that the signal can be measured and evaluated or the data contained in the signal can be examined for accuracy and completeness.

Lotus SmartSuite:-

A popular software suite from Lotus Development Corporation. SmartSuite consists of the 1-2-3 spreadsheet, WordPro word processor (previously known as Ami Pro), Approach database, Freelance Graphics, and the organizer personal information manager.

SmartSuite is also available in a version called NotesSuite, which is integrated with Lotus Notes for groupware applications.

Luggable Computer:-

Slang term for an early portable computer, designed in the mid-1980s, that was just barely transportable. Fortunately, luggable computers disappeared quickly when the modern generation of small, light, and powerful laptop and notebook computers appeared.
