devices transmit simultaneously, a collision occurs and the colliding
devices delay their retransmissions for a random length of time.
DHCP Dynamic Host Control Protocol. A protocol that lets you centrally
manage and automate the assignment of Internet Protocol (IP)
addresses in an organization's network.
Digital Certificate Digital Certificates are blocks of data that are used to identify users and
systems and encrypt their data. Digital Certificates used by SSL adhere
to the X.509 standard.
Distance Vector
Algorithm (DVA)
Routing protocol algorithm that calculates routes for transmitting
packets through networks with multiple paths to a destination.
DNS Domain Name System. This system maps a numerical Internet Protocol
(IP) address to a more meaningful and easy-to-remember name. When
you need to access another device on your network, you enter the
name of the device, instead of its IP address.
endstation A computer, printer or server that is connected to a network.
Ethernet A LAN specification developed jointly by Xerox, Intel and Digital
Equipment Corporation. Ethernet networks use CSMA/CD to transmit
packets at a rate of 10 Mbps over a variety of cables.
Ethernet address See MAC address.
Fast Ethernet An Ethernet system that is designed to operate at 100Mbps.
forwarding The process of sending a packet toward its destination using a
networking device.
Forwarding Database See Switch Database.
filtering The process of screening a packet for certain characteristics, such as
source address, destination address, or protocol. Filtering is used to
determine whether traffic is to be forwarded, and can also prevent
unauthorized access to a network or network devices.
flow control A mechanism that prevents packet loss during periods of congestion on
the network. Packet loss is caused when devices send traffic to an
already overloaded port on a Switch. Flow control prevents packet loss
by inhibiting devices from generating more traffic until the period of
congestion ends.
