Glossary of Network Terms
•
10Base2
. One Part of the IEEE 802 specification using coaxial cable
also called
thin wire Ethernet
. The
10
indicates 10 Mbps transmission,
base
indicates that it is a baseband medium, and the
2
indicates that the
segment(s) can be (almost) 200 meters in length.
•
10Base5
. One Part of the IEEE 802 specification using thicker coaxial
cable also called
thick wire Ethernet
. The
10
indicates 10 Mbps
transmission,
base
indicates that it is a baseband medium, and the 5
indicates that the segment(s) can be up to 500 meters in length.
•
10BaseT
. One Part of the IEEE 802 specification using twisted pair
wires also called
twisted pair Ethernet
. The
10
indicates 10 Mbps
transmission,
base
indicates that it is a baseband medium, and the
T
indicates twisted pair wiring. Segments can be up to 100 meters in
length.
•
ACK
. The name given to network traffic that acts as an
acknowledgment, or the field in a network transmission unit that
indicates it as an acknowledgment.
•
Acknowledgment
. A response from a host indicating that a previous
transmission has been received.
•
Address
. A number or group of numbers that uniquely identifies a
network node within its own network (or internetwork).
•
Address Resolution
. The process of relating a logical address (like an
IP address) to a physical address (like the MAC address of a network
interface).
•
Anonymous FTP
. An instance of the File Transfer Protocol (FTP)
application that permits individuals who do not have explicit
authorization to perform file transfers with a host anonymously by
using a generic user ID to log in and (usually) their e-mail address as a
password.
•
Application
. A program that provides functionality to end users or
systems.
•
Architecture
. The structure of a system, a description of which can be
used to re -create the system; for example, the way the TCP/IP protocols
interact can be considered an interwork architecture; a physical
network’s architecture is defined by the systems components that make
it up (routers, servers, cabling, and attached hosts).
•
ARP
. Address Resolution Protocol; the protocol used in TCP/IP
networks to relate IP addresses with physical network addresses of
network interfaces.
•
ASCII
. American Standard Code for Information Interchange;
generally refers to standard seven-bit text with a limited number of
nontext characters.
•
Asynchronous
. A method of transmitting data that does not require
synchronization between hosts; instead, data must be “framed” with
extra bits to identify the beginning and end of each byte sent.
•
Bandwidth
. The volume of data a communications link is capable of
carrying, usually measured in bits; typical telephone link provide up to
28.8 Kbps, typical Ethernet links provide up to 10 Mbps; see
Latency
.
