A unique user-assigned identification number associated with a host that identifies a
particular device to other hosts during network transactions.
NEWT is a TCP/IP communication stack for Microsoft Windows. NEWT provides users a
degree of network access previously only available to workstation and mainframe users.
Network File System. An application of IP developed by SUN Microsystems that permits
one computer to access another computer’s file system as if it were local.
Network Information Center. Assigns IP addresses and network numbers per request
submitted by an organization. The number assigned is appropriate to the number of host
devices on the network.
Packet Internet Groper. A program that is useful for testing and debugging networks. It
sends an Echo packet to the specified host, and waits for a response. It reports success or
failure and statistics about its operation.
Point-to-Point Protocol. Serial protocol used for operation in a TCP/IP network, as
specified by Internet RFC 1661.
A set of rules that determines the behavior of devices in achieving and maintaining
communication.
Random Access Memory
.
Read/write memory that is volatile and loses its contents when
power is removed.
Files, devices, and users not attached to your local DTE.
The computer receiving the network command.
Request For Comment. The set of documents published by the Internet Engineering Task
Force that describes Internet protocol and policies.
A device that connects LANs by dynamically routing data according to destination and
available routes.
A device that offers a specific service, such as database management, to a client.
Serial Link Internet Protocol. Protocol for serial operation in an Internet network.
Structure of Management Information. The rules used to define the objects that can be
accessed via a network management protocol.
Simple Network Management Protocol. Protocol for open networking management.
A group of drives that work together to span the layers in the network protocol hierarchy.
An IP addressing standard in which a portion of the host address can be used to create
multiple network addresses that are logically a subdivision of the network address.
The subnet portion of an IP address. In a subnetted network, the host portion of an IP
address is split into a subnet portion and a host portion using an address (subnet) mask.
This allows a site to use a single IP network address for multiple physical networks.
Identifies the subnet field of a network address. The subnet mask is a 32-bit Internet
address written in dotted-decimal notation with all the 1s in the network and subnet
portions of the address.
Transmission Control Protocol. An Internet standard transport layer protocol defined in
STD 7, RFC 793. It is connection-oriented and stream-oriented.
Transmission Control Protocol/Internet Protocol. The dominant protocol suite in the
worldwide Internet, TCP allows a process on one machine to send data to a process on
another machine using the IP. TCP can be used as a full-duplex or one-way simplex
connection.
