is responsible for network interface card (NIC) to network interface card communications
Data Link Layer
Without the data link layer, network layer protocols such as IP, would have to make provisions for connecting to every type of media that could exist along a delivery path.
T
IEEE 802 LAN/MAN standards are specific to Ethernet LANs, wireless LANs (WLAN), wireless personal area networks (WPAN) and other types of local and metropolitan area networks
T
The IEEE 802 LAN/MAN data link layer consists of the following two sublayers:
Logical Link Control (LLC)
Media Access Control (MAC)
The MAC sublayer controls the NIC and other hardware that is responsible for sending and receiving data on the wired or wireless LAN/MAN medium.
T
The LLC sublayer takes the network protocol data, which is typically an IPv4 or IPv6 packet, and adds Layer 2 control information to help deliver the packet to the destination node
T
The framing process provides important delimiters to identify fields within a frame. These delimiting bits provide synchronization between the transmitting and receiving nodes
Frame delimiting
Provides source and destination addressing for transporting the Layer 2 frame between devices on the same shared medium
Addressing
Includes a trailer used to detect transmission errors.
Error Detection
The MAC sublayer also provides media access control, allowing multiple devices to communicate over a shared (half-duplex) medium. Full-duplex communications do not require access control.
T
Router interfaces encapsulate the packet into the appropriate frame.
T
What is another name for the OSI data link layer?
Layer 2
