Chapter 7 notes
Ethernet is in association with which layer and which sublayer
Data Link layer
MAC sublayer
MAC Sublayer is responsable for
Data encapsulation and accessing the media
What does FCS stand for
Frame check sequence
Unicast MAC Address
A unicast MAC address is the unique address that is used when a frame is sent from a single transmitting device to a single destination device.
Broadcast MAC Address
An Ethernet broadcast frame is received and processed by every device on the Ethernet LAN.
Multicast MAC Address
An Ethernet multicast frame is received and processed by a group of devices on the Ethernet LAN that belong to the same multicast group.
QoS
quality of service
The two forwarding methods of a switching data between network ports
Store-and forward switching
Cut-through switching
Advantages of Cut-through switching
Lowest level of latency
Advantage of Store-and-forward switching
determines if a frame has errors before propagating the frame.
Port-based memory and
Shared memory
are example of
Memory Buffering Methods
What is (auto-MDIX) used for
When enabled, the switch automatically detects the type of cable attached to the port and configures the interfaces accordingly.
an optional function found on most Ethernet switches and NICs. It enables two devices to automatically negotiate the best speed and duplex capabilities.
Autonegotiation
