Which one of the following is a transport layer protocol?a)stream cont...
Transport Layer Protocol
The transport layer is the fourth layer of the OSI (Open Systems Interconnection) model and is responsible for ensuring reliable and efficient data transfer between end devices. It establishes a connection, breaks data into smaller segments, and reassembles them at the receiving end.
There are several transport layer protocols, but the correct answer to the given question is the Stream Control Transmission Protocol (SCTP). Let's understand why:
SCTP (Stream Control Transmission Protocol)
SCTP is a transport layer protocol that provides reliable, ordered, and error-checked delivery of messages between applications. It is designed to support the transmission of real-time data and is often used for voice and video streaming applications.
Other Options:
Let's briefly discuss the other options provided in the question:
- Internet Control Message Protocol (ICMP): ICMP is a network layer protocol used for diagnostic and error reporting purposes. It is responsible for sending error messages and operational information about network conditions.
- Neighbor Discovery Protocol (NDP): NDP is a network layer protocol used in IPv6 networks. It is responsible for discovering neighboring nodes and managing address resolution, duplicate address detection, and router discovery.
- Dynamic Host Configuration Protocol (DHCP): DHCP is an application layer protocol used for dynamically assigning IP addresses to devices on a network. It provides a way for devices to obtain an IP address, subnet mask, default gateway, and other network configuration parameters automatically.
Conclusion
In summary, the correct answer is option A, the Stream Control Transmission Protocol (SCTP). SCTP is a transport layer protocol that provides reliable and ordered delivery of messages. The other options provided in the question are either network layer protocols (ICMP, NDP) or application layer protocols (DHCP).
