Glossary G-45
tracert A Trace Route command-line tool that shows every router interface through
which a TCP/IP packet passes on its way to a destination.
trailer One of the three sections of a packet component. The exact content of the
trailer varies depending on the protocol, but it usually includes error checking in
the form of a cyclical redundancy check (CRC).
Transmission Control Protocol (TCP) The TCP/IP protocol for sequenced data.
See also Transmission Control Protocol/Internet Protocol (TCP/IP).
Transmission Control Protocol/Internet Protocol (TCP/IP) An industry standard
suite of protocols providing communications in a heterogeneous environment.
In addition, TCP/IP provides a routable enterprise networking protocol and
access to the Internet and its resources. It is a transport layer protocol that actually
consists of several other protocols in a stack that operates at the session layer.
Most networks support TCP/IP as a protocol. See also Internet Protocol (IP).
transport driver interface (TDI) An interface that works between the file-system
driver and the transport protocols, allowing any protocol written to TDI to communicate
with the file-system drivers.
transport layer The fourth layer of the OSI reference model. It ensures that messages
are delivered error-free, in sequence, and without losses or duplications.
This layer repackages messages for efficient transmission over the network. At the
receiving end, the transport layer unpacks the messages, reassembles the original
messages, and sends an acknowledgment of receipt. See also Open Systems Interconnection
(OSI) reference model.
transport protocol A protocol that provides for communication sessions between
computers and ensures that data can move reliably between computers.
Traverse Folder A permission that allows or denies moving through folders to
access other files or folders, even when the user has no permissions for the traversed
folder (the folder that the user is moving through).
tree A grouping of hierarchical arrangements of one or more Windows 2000 domains
that share a contiguous namespace.
Trojan horse virus A type of virus that appears to be a legitimate program that
might be found on any system. A Trojan horse virus can destroy files and cause
physical damage to disks.
trust relationship A trust relationships is a link between domains that enables passthrough
authentication, in which a user has only one user account in one domain
but can access the entire network. User accounts and global groups defined in a
trusted domain can be given rights and resource permissions in a trusting domain,
even if those accounts do not exist in the trusting domain’s database. A trusting
domain honors the logon authentication of a trusted domain.
