Definition
Advanced High-performance bus
Cyclic Redundancy Check
Direct Memory Access
64 bit entity
Frame Check Sequence (CRC)
A (part of an) Ethernet frame; one or multiple fragments can add up to a single
Ethernet frame.
An Ethernet frame consists of destination address, source address, length
type field, payload and frame check sequence.
16 bit entity
Local Area Network
Media Access Control sublayer
Media Independent Interface
MII management
An 8 bit data entity, used in lieu of "byte" by IEEE 802.3
A frame that is transported across Ethernet; a packet consists of a preamble,
a start of frame delimiter and an Ethernet frame.
