Correct option is D
In IP networking, a protocol field value of
0x06 specifies that the
TCP (Transmission Control Protocol) is being used. This value in the IP header indicates that the data payload is managed by TCP, providing reliable, ordered, and error-checked delivery of data between applications.
Important Key Points:
1.
Protocol Identifier: The protocol field in the IP header uses hexadecimal codes to represent different protocols; 0x06 corresponds to TCP.
2.
Reliable Transmission: TCP is a connection-oriented protocol, ensuring reliable data delivery through error-checking and retransmissions if needed.
3.
IP Header Function: The IP header includes protocol information to inform routers and devices of the type of payload being carried.
Knowledge Booster:
·
UDP: Represented by the protocol field value 0x11 (hexadecimal), UDP is a connectionless protocol, providing faster but less reliable transmission.
·
IGMP: Used for managing multicast groups in IP networks but has a different protocol number.
·
ICMP: Represented by the protocol field 0x01, ICMP is used for network diagnostics and error messages.
·
RIP: A routing protocol that operates at the application layer and does not have a protocol field designation like TCP in the IP header.
