A set of devices that receive broadcast frame originated from any device within the set. All devices in the same VLAN are in the same broadcast domain.

An Ethernet frame sent with a destination address FFFF.FFFF.FFFF meaning that the frame should be delivered to all hosts in the LAN.

A set of NICs for which a frame sent by a NIC could result in a collision with a frame sent by any other NIC in the same collision domain.

Cut-through switching

One of the three options of internal processing in some models of the cisco LAN switches in which the frame is forwarded as soon as possible, including forwarding bits of the frame before the whole frame is received.

is the process in which Switches forward Broadcast, unknown unicast and multicast (some times) out all the other ports except the port where it came from.

Fragment-free-switching

The first bits of the frame may be forwarded before the entire frame is received, but not until first 64 bytes of the frame are received, in which case in a well designed LAN collision fragments should not occur as a result of this forwarding logic.

The process in LAN design by which every switch port connects to a single device creating a separate collision domain per interface.

The process of breaking large amount of data from an application into pieces appropriate in size to be sent thorough the network.

Spanning Tree Protocol (STP)

A bridge protocol allowing a switch to dynamically work around loops. Switches exchange Bridge Protocol Data Unit (BPDU) message with other bridges to detect loops, and remove the loops by shutting down the selected bridge interface.

Store-and-forward switching

One of the three processing options in some cisco LAN switches in which Ethernet frame must be completely received before the switch can begin forwarding the first bit of the fame.

Unknown-unicast-frame

An Ethenet frame whose destination MAC address is not listed in the MAC address table of the switch, so the switch must flood the frame.

A group of devices connected to one of more switches with the devices grouped in to a single broadcast domain through switch configurations.

Broadcast frame	An Ethernet frame sent with a destination address FFFF.FFFF.FFFF meaning that the frame should be delivered to all hosts in the LAN.
Collision Domain	A set of NICs for which a frame sent by a NIC could result in a collision with a frame sent by any other NIC in the same collision domain.
Cut-through switching	One of the three options of internal processing in some models of the cisco LAN switches in which the frame is forwarded as soon as possible, including forwarding bits of the frame before the whole frame is received.
Flooding	is the process in which Switches forward Broadcast, unknown unicast and multicast (some times) out all the other ports except the port where it came from.
Fragment-free-switching	The first bits of the frame may be forwarded before the entire frame is received, but not until first 64 bytes of the frame are received, in which case in a well designed LAN collision fragments should not occur as a result of this forwarding logic.
Microsegmentation	The process in LAN design by which every switch port connects to a single device creating a separate collision domain per interface.
Segmentation	The process of breaking large amount of data from an application into pieces appropriate in size to be sent thorough the network.
Spanning Tree Protocol (STP)	A bridge protocol allowing a switch to dynamically work around loops. Switches exchange Bridge Protocol Data Unit (BPDU) message with other bridges to detect loops, and remove the loops by shutting down the selected bridge interface.
