Question: The network layer protocol for internet is __________
| A | ethernet |
| B | internet protocol |
| C | hypertext transfer protocol |
| D | file transfer protocol |
Answer: B
Explanation: There are several protocols used in Network layer. Some of them are IP, ICMP, CLNP, ARP, IPX, HRSP etc. Hypertext transfer protocol is for application layer and ethernet protocol is for data link layer.
The bedrock protocol governing data transmission across the internet and other networks is the Internet Protocol (IP), situated within the network layer. IP constitutes an indispensable element of the TCP/IP protocol suite, an assemblage of protocols forming the bedrock of internet communication.
Functioning within the OSI (Open Systems Interconnection) model’s network layer (Layer 3), the Internet Protocol adheres to a conceptual framework that systematizes communication functions into seven tiers. This layer is charged with the task of directing and forwarding data packets between distinct networks. Notably, IP offers a connectionless, best-effort mechanism for packet conveyance, implying that delivery guarantees, sequential accuracy, and error-free transmission are not assured.
The Internet Protocol manifests in two prominent iterations: IPv4 and IPv6. The ubiquitously employed IPv4 employs 32-bit addresses, affording approximately 4.3 billion distinctive addresses. Yet, the surge in internet expansion coupled with IPv4 address exhaustion ushered in the advent of IPv6. Characterized by 128-bit addresses, IPv6 boasts a considerably expanded address space and enhanced routing capabilities.
The IP protocol works in conjunction with the Transport Layer (Layer 4) protocols, such as Transmission Control Protocol (TCP) or User Datagram Protocol (UDP), to ensure end-to-end communication between hosts. TCP/IP, the combination of IP and TCP, is the most widely used protocol for internet communication, providing reliable, connection-oriented, and error-checked data transmission.
To recap, the Internet Protocol (IP) is the network layer protocol responsible for routing and forwarding data packets across the internet and other networks. It is a core component of the TCP/IP protocol suite and operates at the network layer (Layer 3) of the OSI model.
