Ethernet Meltdown
 
Ethernet Meltdown refers to an event that causes saturation, or near saturation, on an Ethernet. It usually results from illegal or misrouted packets and typically lasts only a short time.
 
 
Ethernet VPN
 
Ethernet VPN refers to a group of technologies to provide Virtual Private Network services over the Internet between the Ethernet LANs. One of the Ethernet VPN technologies is based on Virtual Private LAN Services (VLPS) and Multiprotocol Label Switching (MPLS), which provides more benefits than other alternative layer 2 or 3 VPN technologies.
 
 
Fibre Optics
 
Fibre Optics is a physical method for the transmission of information (audio, video, and data) using optic fibre cable and light. Light is modulated and transmitted over high purity, hair-thin fibres of glass. The bandwidth capacity of fibre optic cable is much greater than that of conventional cable or copper wire.
 
 
Fibre-optic Cable
 
Fibre-optic Cable is the physical medium capable of conducting modulated light transmission. Compared with other transmission media, fibre-optic cable is not susceptible to electromagnetic interference and is capable of higher data rates.
 

Fibre Channel
 
Fibre Channel, also known as Fibre Channel, is a set of related physical layer networking standards for high-performance disk storage networking of corporate networks. Fibre Channel supports functions such as data backups, clustering and replication. Fibre Channel can utilize copper wiring. However, copper limits Fibre Channel to a maximum recommended reach of 30 meters. When using more expensive fibre optic cables, Fibre Channel reaches to 10 kilometres.
 

 
Front End
 
Front End refers to a node or software program, such as a web browser, that requests services of a back end such as a database
 

 
Full Duplex
 
Full Duplex transmission indicates the transmission of data in two directions simultaneously. For example, on a local area network with full-duplex transmission, one workstation can be sending data on the line while another workstation is receiving data. On the other hand, a half duplex transmission indicates that data transmission happens only in one direction at a time.
 
 
Gb: Gigabit
 
Gigabit (Gb), approximately 1,000,000,000 bits, is a measure of computer data storage.
 

GB: Gigabyte
 
Gigabyte (GB), approximately 1,000,000,000 bytes (one byte is 8 bits), is a measure of computer data storage.
 

 
GBIC: Gigabit Interface Converter
 
Gigabit Interface Converter (GBIC) is a standard for transceivers, commonly used with gigabit Ethernet and fibre channel.
 
 
Gbps: Gigabits per Second
 
Gigabits per Second (Gbps) is a measure of data transfer speed in networking. Gigabytes per Second (GBps) is eight times more than the Gigabits per Second (Gbps).
 
 
GBps: Gigabytes per Second
 
Gigabytes per Second (GBps) is a measure of data transfer speed in networking. Gigabytes per Second (GBps) is eight times more than the Gigabits per Second (Gbps).
 
 
Gigabit Ethernet
 
Gigabit Ethernet is a type of the Ethernet with speed tenfold over the fast Ethernet supporting a theoretical maximum data rate of 1000 Mbps. It uses shorter frames with carrier Extension. It is defined in the IEEE 802.3z and 802.3ab, supplement to the IEEE 802.3 base standards.
 

Grid Network
 
A grid network consists of a number of computer systems connected in a grid topology. In a regular grid topology, each node in the network is connected with two neighbours along one or more dimensions. If the network is one-dimensional, and the chain of nodes is connected to form a circular loop, the resulting topology is known as a ring.
 
 
Half-Duplex
 
Half-duplex is a data transmission method in which data can be transmitted in both directions on a signal carrier, but not at the same time. For example, on a local area network using a technology that has half-duplex transmission, one workstation can send data on the line and then immediately receive data on the line from the same direction in which data was just transmitted. On the other hand, full-duplex transmission implies that data are transmitted in both directions simultaneously.
 

 
Hub
 
The Hub (or repeater) is a device that accepts numerous Ethernet connections from network devices and cross-connects them. Data arriving via the receive pair of one connection is regenerated and sent out on the transmit pair to all connected devices except for the device that originated the transmission.
 

Hybrid network
 
Hybrid network is an internetwork made up of more than one type of network technology, including LANs and WANs.
