Detailed explanation-1: -Examples of data link protocols are Ethernet, the IEEE 802.11 WiFi protocols, ATM and Frame Relay. 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.
Detailed explanation-2: -The foremost data link layer protocol is the Ethernet protocol. Like the check being placed into the envelope, the Ethernet protocol encapsulates data passed to it from higher layers. It also does the reverse: it decapsulates data that is presented to it from the physical layer.
Detailed explanation-3: -Ethernet is a layer 2 data link protocol that is widely used with the TCP/IP protocol, which resides at layers 3 and 4. To understand network communications, it is essential to learn about the protocol layers (see OSI model).
