What is data link framing?
Framing is a function of the data link layer. It provides a way for a sender to transmit a set of bits that are meaningful to the receiver. Ethernet, token ring, frame relay, and other data link layer technologies have their own frame structures.
What are the types of data link protocol?
Examples of Data Link Layer Protocols
- Synchronous Data Link Protocol (SDLC) –
- High-Level Data Link Protocol (HDLC) –
- Serial Line Interface Protocol (SLIP) –
- Point to Point Protocol (PPP) –
- Link Control Protocol (LCP) –
- Link Access Procedure (LAP) –
- Network Control Protocol (NCP) –
What are the function of data link layer?
The data link layer is responsible for multiplexing data streams, data frame detection, medium access, and error control. It ensures reliable point-to-point and point-to-multipoint connections in a communication network.
What is unacknowledged connectionless service?
Unacknowledged Connectionless Service, as the name suggests, is a service in which data frames are sent or transmitted from destination to source machine without any acknowledgment and without connection established among source and destination machine.
Why do we use framing in data link layer?
Framing in data link layer is a point-to-point connection between the sender and receiver. The framing is the primary function of the data link layer and it provides a way to transmit data between the connected devices. Framing use frames to send or receive data.
What are the sub layers of data link layer?
The data link layer within 802.11 consists of two sublayers: logical link control (LLC) and media access control (MAC).
What are responsibilities of data link layer?
The main functions of data link layer include framing, error detection and correction, acknowledgement, flow control, ensuring well-defined reliable service interface to the network layer, encapsulating packets from network layer to frames, etc.
Which is data link layer protocol?
The Data Link Layer protocols are Ethernet, token ring, FDDI and PPP. An important characteristic of a Data Link Layer is that datagram can be handled by different link layer protocols on different links in a path. For example, the datagram is handled by Ethernet on the first link, PPP on the second link.
What is function of data link layer?
2 Data Link Layer. The data link layer is responsible for multiplexing data streams, data frame detection, medium access, and error control. It ensures reliable point-to-point and point-to-multipoint connections in a communication network.
