DCN - Module 6

operates in the data link layer and the physical layer.

ETHERNET (SUBLAYERS):

(IEEE 802.2) Places information in the frame to identify which network layer protocol is used for the frame.

ETHERNET (SUBLAYERS):

(IEEE 802.3, 802.11, or 802.15)

Responsible for data encapsulation and media access control, and provides data link layer addressing.

ETHERNET (ENCAPSULATION ELEMENTS):

internal structure of the Ethernet frame.

ETHERNET (ENCAPSULATION ELEMENTS):

includes both a source and destination MAC address to deliver the Ethernet frame from the Ethernet NIC to the Ethernet NIC on the same LAN.

ETHERNET (ENCAPSULATION ELEMENTS):

includes a frame check sequence (FCS) trailer used for error detection.

The minimum Ethernet frame size is __ bytes

The maximum Ethernet frame size is ____ bytes

Any frame less than 64 bytes in length is considered a

“*****” or “****” and is automatically discarded.

Frames with more than 1500 bytes of data are considered

“****” or “***”.
