COMPUTER NETWORKING

Detailed explanation-1: -The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks–hence, the name internet.

Detailed explanation-2: -Layer 3, the network layer, is most commonly known as the layer where routing takes place. A router’s main job is to get packets from one network to another. Layer 3 protocols and technologies allow for network-to-network communications.

Detailed explanation-3: -Internet Layer. This layer, also known as the network layer, accepts and delivers packets for the network. This layer includes the powerful Internet Protocol (IP), the Address Resolution Protocol (ARP), and the Internet Control Message Protocol (ICMP).

Detailed explanation-4: -The Internet layer of the TCP/IP model aligns with Layer 3 (network) of the OSI model. This is where IP addresses and routing reside. When data is transmitted from a node on one LAN to a node on another one, the Internet layer is used. IPv4 and IPv6 (among others) are Internet Layer TCP/IP protocols.
