CoS (Class of Servce) - The 802 .1p priority scheme .
CoS provides a method for tagging packets with priority
information . A CoS value between 0-7 is added to the
Layer II header of packets, where zero is the lowest priority
and seven is the highest .
DDNS (Dynamc Doman Name System) - Allows the
hosting of a website, FTP server, or e-mail server with a
fixed domain name (e .g ., www .xyz .com) and a dynamic IP
address .
Default Gateway - A device that forwards Internet traffic
from your local area network .
DHCP (Dynamc Host Confguraton Protocol) - A
networking protocol that allows administrators to assign
temporary IP addresses to network computers by "leasing"
an IP address to a user for a limited amount of time, instead
of assigning permanent IP addresses .
DHCP Clents - An Internet host using DHCP to obtain
configuration parameters, such as a network address .
DHCP Server - An Internet host that returns configuration
parameters to DHCP clients .
DNS (Doman Name Server) - The IP address of your
ISP's server, which translates the names of websites into
IP addresses .
Doman - A specific name for a network of computers .
Download - To receive a file transmitted over a network .
DSL (Dgtal Subscrber Lne) - An always-on broadband
connection over traditional phone lines .
DSCP (DffServ Code Pont) - Provides a method of
tagging IP packets with QoS priority information .
Dynamc IP Address - A temporary IP address assigned
by a DHCP server .
EIGRP (Enhanced Interor Gateway Routng Protocol)
- Provides fast convergence, support for variable-length
subnet mask, and supports multiple network layer
protocols .
Encrypton - Encoding data transmitted in a network .
Ethernet - IEEE standard network protocol that specifies
how data is placed on and retrieved from a common
transmission medium .
Frmware - The programming code that runs a networking
device .
Flow Control - Enables lower speed devices to
communicate with higher speed devices . This is
implemented by the higher speed device refraining from
sending packets .
FTP (Fle Transfer Protocol) - A protocol used to transfer
files over a TCP/IP network .
24-Port 10/100 + 4-Port Ggabt Swtch wth WebVew and Power over Ethernet
Full Duplex - The ability of a networking device to receive
and transmit data simultaneously .
GARP (General Attrbutes Regstraton Protocol) -
Registers client stations into a multicast domain .
Gateway - A device that interconnects networks with
different, incompatible communications protocols .
GBIC (GgaBt Interface Converter) - A hardware module
used to attach network devices to fiber-based transmission
systems . GBIC converts the serial electrical signals to serial
optical signals and vice versa .
GVRP (GARP VLAN Regstraton Protocol) - Registers
client stations into a VLANs .
Half Duplex - Data transmission that can occur in two
directions over a single line, but only one direction at a
time .
HTTP (HyperText Transport
communications protocol used to connect to servers on
the World Wide Web .
HTTPS (HyperText Transport Protocol Secure) - An
extension to the standard HTTP protocol that provides
confidentiality by encrypting the traffic from the website .
By default this protocol uses TCP port 443 .
ICMP (Internet Control Message Protocol) - Allows the
gateway or destination host to communicate with the
source host . For example, to report a processing error .
IGMP (Internet Group Management Protocol) - Allows
hosts to notify their local switch or router that they want
to receive transmissions assigned to a specific multicast
group .
IP (Internet Protocol) - A protocol used to send data over
a network .
IP Address - The address used to identify a computer or
device on a network .
IPCONFIG - A Windows 2000 and XP utility that displays
the IP address for a particular networking device .
IPSec (Internet Protocol Securty) - A VPN protocol used
to implement secure exchange of packets at the IP layer .
ISP (Internet Servce Provder) - A company that provides
access to the Internet .
Jumbo Frames - Enable transporting identical data in
fewer frames . Jumbo Frames reduce overhead, lower
processing time, and ensure fewer interrupts .
LAG (Lnk Aggregated Group) - Aggregates ports or
VLANs into a single virtual port or VLAN .
LAN - The computers and networking products that make
up your local network .
