G-4 Glossary
asynchronous transmission A form of data transmission in which information is
sent one character at a time, with variable time intervals between characters. Asynchronous
transmission does not rely on a shared timer that allows the sending and
receiving units to separate characters by specific time periods. Therefore, each
transmitted character consists of a number of data bits (which compose the character
itself) preceded by a start bit and ending in an optional parity bit followed by
a 1-, 1.5-, or 2-stop bit.
ATM See Asynchronous Transfer Mode (ATM).
auditing A process that tracks network activities by user accounts and is a routine
element of network security. Auditing can produce records of users who have
accessed—or attempted to access—specific resources; help administrators identify
unauthorized activity; and track activities such as logon attempts, connection and
disconnection from designated resources, changes made to files and directories,
server events and modifications, password changes, and logon parameter
changes.
audit policy Defines the types of security events that Windows XP Professional
records in the security log on each computer.

Control Protocol/Internet Protocol (TCP/IP) is configured for dynamic
addressing and a Dynamic Host Configuration Protocol (DHCP) server is not available.
