L0phtCrack
L0phtCrack is a password auditing and recovery application. It uses multiple assessment methods to assist administrators in reducing security risks. L0phtCrack helps to identify and remediate security vulnerabilities that result from the use of weak or easily guessed passwords and recover Windows and Unix account passwords to access user and administrator accounts whose passwords are lost or to streamline migration of users to another authentication system. Additionally, some versions of L0phtCrack can process accounts using pre-computed password tables that contain trillions of passwords.

- L1 cache
Short for Level 1 cache, a memory cache built into the microprocessor. See under cache. The L1 cache is also called the primary cache.
- L2 cache
Short for Level 2 cache, cache memory that is external to the microprocessor. In general, L2 cache memory, also called the secondary cache, resides on a separate chip from the microprocessor chip. Although, more and more microprocessors are including L2 caches into their architectures.
- L2TP
Short for Layer Two (2) Tunneling Protocol, an extension to the PPP protocol that enables ISPs to operate Virtual Private Networks (VPNs). L2TP merges the best features of two other tunneling protocols: PPTP from Microsoft and L2F from Cisco Systems. Like PPTP, L2TP requires that the ISP’s routers support the protocol.
- L3 cache
As more and more processors begin to include L2 cache into their architectures, Level 3 cache is now the name for the extra cache built into motherboards between the microprocessor and the main memory. Quite simply, what was once L2 cache on motherboards now becomes L3 cache when used with microprocessors containing built-in L2 caches.
- LACNIC
The abbreviation for the Latin American and Caribbean Internet Addresses Registry, one of four regional Internet registries that supply and administer IP addresses. LACNIC focuses on the Latin American and Caribbean region.
