A few examples of application layer protocols are the Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), Post Office Protocol (POP), Simple Mail Transfer Protocol (SMTP), and Domain Name System (DNS).
What is link control in data link layer?
Data Link Control is the service provided by the Data Link Layer to provide reliable data transfer over the physical medium. For example, In the half-duplex transmission mode, one device can only transmit the data at a time.
What do you mean by data link layer?
The data link layer is the protocol layer in a program that handles the moving of data into and out of a physical link in a network. The data link layer also determines how devices recover from collisions that may occur when nodes attempt to send frames at the same time.
What are physical layer protocols?
Examples of protocols that use physical layers include:
What is protocol data unit in network layer?
A protocol data unit is information delivered as a unit among peer entities of networks containing control information, address information or data. In layered systems, PDU represents a unit of data specified in the protocol of a given layer, which consists of protocol control information and user data.
Which of the following protocols are examples of TCP IP data link layer protocols?
Examples of data link protocols are Ethernet, Point-to-Point Protocol (PPP), HDLC and ADCCP. In the Internet Protocol Suite (TCP/IP), the data link layer functionality is contained within the link layer, the lowest layer of the descriptive model, which is assumed to be independent of physical infrastructure.
