Labeling
(Context: General, Technology Management)
Definition
Proper labeling of all back-up media is critical to the timely restoration of data. There must be a correlation between the data, the media and the date the back-up was performed. The use of a back-up log would indicate the media set that contains the file(s) to be restored. The method used will be based primarily on the business objectives.

Lag
(Context: )
Definition
A modification of a logical relationship that directs a delay in the successor activity. For example, in a finish-to-start dependency with a 10-day lag, the successor activity cannot start until ten days after the predecessor activity has finished.
PMBOK
LambdaRail
(Context: )
Definition
National LambdaRail is a high-speed national computer network infrastructure in the United States that runs over fiber-optic lines, and is the first transcontinental Ethernet network. The name is shared by the organization of research institutions that developed the network, and, to date, plans to continue developing it. LambdaRail is similar to the Abilene Network, but LambdaRail permits deeper experimentation than Abilene does.
National LambdaRail is a high-speed national computer network infrastructure in the United States that runs over fiber-optic lines, and is the first transcontinental Ethernet network. The name is shared by the organization of research institutions that developed the network, and, to date, plans to continue developing it. LambdaRail is similar to the Abilene Network, but LambdaRail permits deeper experimentation than Abilene does.
It is primarily oriented to aid terascale computing efforts and to be used as a network testbed for experimentation with next-generation large-scale networks. National LambdaRail is a university-based and -owned initiative, in contrast with Abilene and Internet2, which are university-corporate sponsorships. This gives universities more control to use the network for these research projects. National LambdaRail also supports a production layer on its infrastructure.
Links in the network use dense wavelength-division multiplexing (DWDM), which allows up to 32 or 40 individual optical wavelengths to be used (depending on hardware configuration at each end). At present, individual wavelengths are used to carry a 10-gigabit Ethernet signal.
Erv Blythe is the Chair of the LambdaRail Board of Directors. In 2004, LambdaRail
Largest Contentful Paint (LCP)
(Context: General, Software)
Definition
Reports the render time of the largest image or text block visible within the viewport, relative to when the page first started loading.
Late Finish Date (LF)
(Context: )
Definition
In the critical path method, the latest possible point in time that a schedule activity may be completed based upon the schedule network logic, the project completion date, and any constraints assigned to the schedule activities without violating a schedule constraint or delaying the project completion date. The late finish dates are determined during the backward pass calculation of the project schedule network.
PMBOK
Late Start Date (LS)
(Context: )
Definition
In the critical path method, the latest possible point in time that a schedule activity may begin based upon the schedule network logic, the project completion date, and any constraints assigned to the schedule activities without violating a schedule constraint or delaying the project completion date. The late start dates are determined during the backward pass calculation of the project schedule network.
PMBOK
Layout Shift
(Context: General, Software)
Definition
Any time a visible element changes its position from one rendered frame to the next.
Lead
(Context: )
Definition
A modification of a logical relationship that allows an acceleration of the successor activity. For example, in a finish-to-start dependency with a ten-day lead, the successor activity can start ten days before the predecessor has finished.
PMBOK
Leadership
(Context: )
Definition
The way in which the project manager influences the project team to behave in a manner that will facilitate project goal achievement.
Least Privilege
(Context: )
Definition
The minimum level of data, functions, and capabilities necessary to perform a user's duties.
Lessons Learned
(Context: )
Definition
The learning gained from the process of performing the project. Lessons learned may be identified at any point. Also considered a project record, to be included in the lessons learned knowledge base.
PMBOK
Level of Effort (LOE)
(Context: )
Definition
Support-type activity (e.g., seller or customer liaison, project cost accounting, project management, etc.) that does not readily lend itself to measurement of discrete accomplishment. It is generally characterized by a uniform rate of work performance over a period of time determined by the activities supported.
PMBOK
Life-Cycle Cost
(Context: )
Definition
The overall estimated cost for a particular object over the time corresponding to the life of the object, including direct and indirect initial costs plus any periodic or continuing costs for operation and maintenance.
(GAO)
Light Weight Access Point Protocol (LWAPP)
(Context: )
Definition
A yet-to-be ratified standard of the IETF that defines interactions between wireless termination points and wireless access controllers. Ratification is expected in mid- 2006.
Lightweight Directory Access Protocol (LDAP)
(Context: )
Definition
A protocol for accessing on-line directory services. LDAP was defined by the IETF to encourage adoption of X.500 directories. The Directory Access Protocol (DAP) was seen as too complex for simple Internet clients to use. LDAP defines a relatively simple protocol for updating and searching directories running over TCP/IP.
Linux
(Context: )
Definition
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, an 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 modified version that is redistributed must in turn be freely available.
Load Balancing
(Context: )
Definition
Requests from clients are distributed across available servers to achieve better utilization of computing resources. In general, load balancing can be based on network traffic, CPU load, relative power of the server, size of the server’s request queue, a simple round robin method, or other mechanisms.
Local Area Network (LAN)
(Context: )
Definition
A private computer network generally on a user's premises and operated within a limited geographical area.
Log
(Context: Software)
Definition
A file that contains data about an event that occurred in an application or operating system.

Log Category
(Context: Software)
Definition
A classification of available event logs.

Logical Relationship
(Context: )
Definition
A dependency between two project schedule activities, or between a project schedule activity and a schedule milestone. The four possible types of logical relationships are: Finish-to-start, Finish-to-finish, Start-to-start, and Start-to-finish.
PMBOK
Logon ID
(Context: )
Definition
An identification code (normally a group of numbers, letters, and special characters) assigned to a particular user that identifies the user to the information system.
Long-Term State
(Context: General, Software)
Definition
Long-term state- The storage of information for extended periods, typically longer than a user’s specific login session, for future reference, compliance, or historical analysis.
Loosely Coupled
(Context: )
Definition
Architectures based on publish/subscribe communications can provide a lightweight and resilient foundation for applications that do not require tight coordination.
Lump Sum Contracts
(Context: )
Definition
This category of contract involves a fixed total price for a well-defined product. Fixed price contracts may also include incentives for meeting or exceeding selected project objectives such as schedule targets.
