IEEE
It is the Institute of Electrical and Electronic Engineers. The IEEE is a
professional technical body promoting the development and
application of technology.
IP Address
At the moment, IP address is a 32-bit binary digit that defines each
sender or receiver of information across an IP network.
IPSec
Internet Protocol Security. It is a suite of protocols used to implement
secure exchange of packets at the IP layer.
ISP
Internet Service Provider. It is a company that provides individuals or
corporations with Internet access and other related services.
corporations with Internet access and other related services.
LAN
Local Area Network is a group of computers and devices sharing a
common communication medium within a small geographical area.
common communication medium within a small geographical area.
Latency
Latency is a time-delay.
MAC Address
MAC is the abbreviation for Media Access Control. The MAC address
is a unique number assigned by the manufacturer to any Ethernet
networking device, such as a network adapter or router that allows a
networking device, such as a network adapter or router that allows a
network to identify the hardware. Unlike IP addresses, this number is
permanent and is therefore a valuable identifier.
Mbps
Mega bits per second. It is a unit of measurement for data
transmission indicating a million bits per second.
MDI
Medium Dependent Interface. On a network hub/switch, a MDI port
(uplink port) connects to another hub/switch using a straight cable.
To connect a MDI port to a computer, a crossover cable is used.
To connect a MDI port to a computer, a crossover cable is used.
MDI-X
Medium Dependent Interface Crossed. On a network hub/switch, a
MDI-X port connects to a computer using a straight cable. To
MDI-X port connects to a computer using a straight cable. To
connect a MDI-X port to another hub/switch, use a crossover cable.
Multicast
A multicast is a packet that is sent to a subset of end stations in a
LAN, or VLAN that belong to a multicast group. If the network is set up
LAN, or VLAN that belong to a multicast group. If the network is set up
correctly, a multicast can only be sent to an end station if it has
joined the relevant group.
joined the relevant group.
NAT
Network Address Translations multiplexes multiple private IP addresses
on the LAN to a single public IP address on the Internet.
on the LAN to a single public IP address on the Internet.
OFDM
Orthogonal Frequency Division Multiplexing. It is a modulation
scheme employed by the IEEE 802.11g standard, which combines
numerous signals of different frequencies to form a single signal for
transmission over a medium.
transmission over a medium.
Packet Filtering
This is a means of discarding unwanted network traffic based on its
originating addresses or the type of data transmitted.
