The data link layer provides error-free transfer of data frames between two devices on the same network. Tanenbaum explains the key functions of the data link layer, including framing, error detection and correction, and flow control. He discusses the different data link layer protocols, such as HDLC, PPP, and Ethernet, and their applications in various network environments. The author also covers the concept of MAC (Media Access Control) addresses and their role in identifying devices on a network.
The network layer is responsible for routing packets between devices on different networks. Tanenbaum explains the key functions of the network layer, including routing, addressing, and congestion control. He discusses the different network layer protocols, such as IP (Internet Protocol), ICMP (Internet Control Message Protocol), and IGMP (Internet Group Management Protocol). The author also covers the concept of subnetting and supernetting, and their role in optimizing network routing. computer networks tanenbaum 6th edition ppt
