Kerberos V5 authentication protocol

An authentication mechanism used to verify user or host identity. The Kerberos V5 authentication protocol is the default authentication service for Windows 2000. Internet Protocol security (IPSec) and the QoS Admission Control Service use the Kerberos protocol for authentication. See also Internet Protocol security (IPSec); Key Distribution Center (KDC).

kernel

The core of layered architecture that manages the most basic operations of the operating system and the computer's processor. The kernel schedules different blocks of executing code, called threads, for the processor to keep it as busy as possible and coordinates multiple processors to optimize performance. The kernel also synchronizes activities among Executive-level subcomponents, such as I/O Manager and Process Manager, and handles hardware exceptions and other hardware-dependent functions. The kernel works closely with the hardware abstraction layer.

key

In Registry Editor, a folder that appears in the left pane of the Registry Editor window. A key can contain subkeys and value entries. For example, Environment is a key of HKEY_CURRENT_USER.

In IP security (IPSec), a value used in combination with an algorithm to encrypt or decrypt data. Key settings for IP security are configurable to provide greater security.

Key Distribution Center (KDC)

A network service that supplies session tickets and temporary session keys used in the Kerberos V5 authentication protocol. In Windows 2000 and Windows XP, the KDC runs as a privileged process on all domain controllers. See also Kerberos V5 authentication protocol.

keyboard filters

Special timing and other devices that compensate for erratic motion tremors, slow response time, and other mobility impairments.

Korn shell (ksh)

A command shell that provides the following functionality: file input and output redirection; command-line editing by using vi; command history; integer arithmetic; pattern matching and variable substitution; command name abbreviation (aliasing); and built-in commands for writing shell programs.
