What else can I help you with?
Why are the source and destination port numbers at the beginning of the TCP header?
That is the way the standard designed the header. They could be placed anywhere as long as everyone understood where in the packet header it was placed.
Why are port numbers included in the TCP header of a segment?
to enable a receiving host to forward the data to the appropriate application
What header that has source of 13357 and destination port of 23?
It is a TCP Header
Which three fields are used in a UDP segment header?
• checksum • destination port • source port
How does a client computer determine what source port number to assign to a UDP header?
The port number is random
Why are port numbers included in the tcp header of segments?
So the destination host knows what port to send it to. If the destination just takes a guess as to what port to send it to and sends an RDP packet to port 80 what do you think is going to happen?
Can oil fron a valve cover leak drip into the header and blow into the exhaust port and out the header?
Yes it sure can and will if the valve covers are leaking oil and the header gaskets are worn out/ leaking.
What are the two basic port numbers?
ephemeral port numbers and well known port numbers
Port number is 16bits what is the minimum header size of a transport layer?
8
What are the two basic types of port numbers?
Ephemeral port numbers and well-known port numbers.
Why to use tcp header?
a tcp header contains the information of the source and destination networks and well as what port to access with out it the packet would not know where to go
What is tcpip header and trailer?
An Ethernet frame has a 14 byte header, a data section, and a 4 byte trailer 14 byte header consist of destination address, source address and type The trailer is for CRC (Cyclic redundancy Check) An Ethernet frame can contain an IP and TCP PDU. IP header most important parts consists of (Version,IHL, Total length,Protocol, source and destination address) In details (Version,Header length,Differentiated services field, total Length, Identification, Flags, fragment offset, Time to live, protocol, header checksum, source and destination address). TCP header most important parts consists of (Source port, Destination port and header Length) In details (Source Port, Destination Port, Sequence number, Acknowledgment number, Header length,Flags,Window and check sum). The details of the IP and TCP header have been taken from a Network protocol Analyzer Wireshark on my own pc.
