TTT

A multiprocessing entity that is one or more sequences of instructions (threads) treated by the control program as a unit of work to be accomplished by the processors. A task has a definite address space shared in common by the individual threads composing the task.

A unique number that identifies an individual program, running at any given time at a workstation. Task numbers are only unique for a given workstation.

Transmission Control Protocol. The major transport protocol in the Internet suite. TCP provides reliable, connection-oriented, full-duplex streams. It uses IP for delivery.

Transmission Control Protocol/Internetwork Protocol. A protocol suite developed by the Advanced Research Projects Agency (ARPA). It includes TCP (Transmission Control Protocol) as the primary transport protocol and IP (Internet Protocol) as the network layer protocol.

1. In computer processing, a sequence of instructions executed as an independent entity and scheduled by system software. A thread is also known as an executable object.

2. Within an Internet discussion group, an ongoing discussion about a particular topic. Sometimes called a conversation.

A set of data items that are global only within each thread. That is, they have separate values for each thread. The data items of one thread cannot be referenced by another thread.

A group of one or more threads as defined by the programmer.

There is one instance of the data items for each thread group. Any change that one thread makes to the value of a thread group global data item affects all the threads in the group.

A thread that performs a request or polls for the occurrence of some event. Polling threads are always running but relinquish control after going through one polling loop. Normally, worker threads either quickly complete the request, or are put to sleep pending the completion of an external event, such as a disk I/O.

Describes a symmetric multiprocessing hardware design in which processors share common memory and are typically hard-wired together over a shared multiplexed hardware bus. NetWare SMP uses this design.

A code that indicates the time that an event happened.

A method of ensuring that all servers in an NDS tree report the same time. Single reference time servers or reference time servers are used to synchronize all other servers.

Transport Level Interface. A STREAMS-based interprocess communication mechanism that provides protocol-independent support for server applications.

Transport Layer Security. An IETF security protocol that contains SSL and other protocols. TLS is compatible with SSL and uses Triple DES encryption.

TSM. An NLM used with LAN drivers.

A set of one or more operations that must be completed together to maintain file and database integrity.

Transactions are backed out because of system failures resulting from hardware problems and power outages at a workstation or the server. But backouts also occur because of problems with applications running on a workstation or because of user intervention at a workstation.

TTS. A NetWare feature that protects database applications from corruption by backing out incomplete transactions that result from a failure in a network component.

TCP. The major transport protocol in the Internet suite. TCP provides reliable, connection-oriented, full-duplex streams. It uses IP for delivery.

TCP/IP. A protocol suite developed by the Advanced Research Projects Agency (ARPA). It includes TCP (Transmission Control Protocol) as the primary transport protocol and IP (Internet Protocol) as the network layer protocol.

TLS. An IETF security protocol that contains SSL and other protocols. TLS is compatible with SSL and uses Triple DES encryption.

TLI. A STREAMS-based interprocess communication mechanism that provides protocol-independent support for server applications.

Short for "NDS tree." A hierarchical structure of objects in the NDS database. The NDS tree includes container objects that are used to organize the network. The structure of the NDS tree can be based on a logical organization of objects, and not necessarily on their physical location.

Any object that has rights to access a network resource such as a directory, file, or object. Rights are granted to objects (making them trustees) by trustee assignments.

A privilege assigned to a user or group for a specific volume, folder, directory, or file. The user or group is known as the trustee. The rights assigned determine the kinds of tasks the trustee can carry out.

Topology Specific Module. An NLM used with LAN drivers.

Transaction Tracking System. A NetWare feature that protects database applications from corruption by backing out incomplete transactions that result from a failure in a network component.

An index of the blocks that pertain to a particular file. When a file exceeds 64 blocks, the traditional NetWare file system creates a turbo FAT index that groups together all FAT entries to the corresponding file. This index enables a large file to be accessed quickly.

A buffer that holds input from the keyboard before it is processed by the NLM.
