10/100Base-T
There are several standards for Ethernet over twisted pair or copper-based computer networking
physical connectivity methods. The currently most widely used of these are 10Base-T, 100Base-
TX, and 1000Base-T (Gigabit Ethernet), running at 10 Mb/s, 100 Mb/s, and 1000 Mb/s (1 Gb/s)
respectively.

802.1 Q/P
IEEE 802.1Q (also known as VLAN Tagging) was a project in the IEEE 802 standards process to
develop a mechanism to allow multiple bridged networks to transparently share the same physical
network link without leakage of information between networks (i.e. trunking). IEEE 802.1Q is
also the name of the standard that resulted from this process, and in common usage it is the name
of the encapsulation protocol used to implement this mechanism over Ethernet networks.
IEEE 802.1P is a standard that provides traffic class expediting and dynamic multicast filtering.
Essentially, it provides a mechanism for implementing Quality of Service (QoS) at the MAC
level.

Category 5
Commonly known as Cat 5, category 5 is a twisted pair cable type designed for high signal
integrity. Many such cables are unshielded but some are shielded. Category 5 has been
superseded by the Category 5e specification. This type of cable is often used in structured cabling
for computer networks such as Ethernet, and is also used to carry many other signals such as
basic voice services, token ring, and ATM (at up to 155 Mb/s, over short distances).

Ethernet
Ethernet is a family of frame-based computer networking technologies for local area networks
(LANs). The name comes from the physical concept of the ether. It defines a number of wiring
and signaling standards for the physical layer, through means of network access at the Media
Access Control (MAC)/Data Link Layer, and a common addressing format.

IGMP snooping
A switch with IGMP snooping enabled screens all IGMP packets between hosts that are
connected to the switch and multicast routers in the network. When the switch detects an IGMP
report from a host for a given multicast group, it adds the host°s port number to the multicast list
for that group. Similarly, if it detects an IGMP Leave request, it removes the host.
