Question 14.14. (TCO 3) Data link layer protocols are not generally defined by RFCs requests for comment (RFCs) as are the upper layers of the TCP/IP suite. Functional protocols and services of the data link layer are described by engineering organizations such as the IEEE, ITU, and ANSI and communication companies. Unlike the upper layer protocols, which are implemented in software only, the data link layer processes occur in both software and hardware. Explain the importance of the Layer 2 standards and protocols for devices, such as NICs and wireless (PCMCIA) adapters, with which a node connects to the physical network. (Points : 10)
