| Membership Reports that it wants to receive messages addressed to |
| a specific multicast group. All hosts conforming to level 2 of the IP |
| multicasting specification require IGMP. |
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 |
| 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. |
LAN | Local Area Network is a group of computers and devices sharing a |
| common communication medium within a small geographical area. |
Latency | Latency is a |
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 |
| 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. |
| Medium Dependent Interface Crossed. On a network hub/switch, a |

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 |
| correctly, a multicast can only be sent to an end station if it has |
| 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. |
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. |
Packet Filtering | This is a means of discarding unwanted network traffic based on its |
| originating addresses or the type of data transmitted. |
