Which portion of a received datagram is decoded and used by the internetwork layer of the tcpip model?
Only the Network Layer (Layer 3) portion of the datagram is used by the Network Layer (Layer 3) portion of the TCP/IP Model. The network portion of the datagram includes IP Addressing information, and things such as TTL (Time to Live), and Datagram Priority markings.
What is datagram Subnet?
datagram subnet is connection oriented network.
What is the difference between datagram and packet?
datagram is used in conectionless n/w e.g. UDP Whereas packets used in connection oriented n/w e.g. ATM X.25 tcp
In the context of tcpip a packet is also known as?

The datagram length field in an IPv4 datagram contains which numeric value?
Total number of bytes in the datagram, including the header.The length of an IP datagram itself is technically measured in bytes. The length field represents the size of both the header and the data portions of the datagram.
The maximum size of an IP datagram including the header is?
The datagram length field in an IP header is 16 bits in length. Therefore, the maximum datagram size an IP datagram can support is 2^16 - 1 = 65,535 bytes
How does UDP verify datagram integrity?
It uses something called a checksum to verify datagram integrity
What does a client do when it has UDP datagrams to send?
When a client wishes to send a UDP datagram there is nothing that they are required to except to send it. The datagram will use a checksum to verify the integrity of the datagram and deliver it where it needs to go.
