What else can I help you with?
The fields in TCP header that are missing from UDP header?
The sequence number, acknowledge number, and Window fields.
What is a layer four header?
In the commonly used TCP/IP communications, that would either be a TCP header, or a UDP header.In the commonly used TCP/IP communications, that would either be a TCP header, or a UDP header.In the commonly used TCP/IP communications, that would either be a TCP header, or a UDP header.In the commonly used TCP/IP communications, that would either be a TCP header, or a UDP header.
How does a client computer determine what source port number to assign to a UDP header?
The port number is random
What is udp header?
8 bytes
How many fields are there in IPv4 header?
UDP is a Transport layer protocol or fourth layer protocol. UDP is a connection less protocol used in transport layer. UDP header have four fields in total .
How do you get IP header of a UDP message?
Did you try Wireshark?
What has port numbers in its header?
both tcp and udp
Why does the TCP use a sequence number in the header?
To reassemble the segments into data.
Udp header contains how many headers?
The UDP (User Datagram Protocol) header contains a total of four fields, which are: source port, destination port, length, and checksum. Each of these fields is 2 bytes long, making the total UDP header size 8 bytes. Unlike some protocols, UDP does not include additional headers like options or flags, keeping it simple and lightweight for fast transmission.
How is the checksum evaluated in UDP?
In UDP, the checksum is evaluated by taking the 16-bit one's complement sum of the UDP header, the UDP data (payload), and a pseudo-header that includes the source and destination IP addresses, protocol number, and UDP length. If the sum exceeds 16 bits, the overflow is wrapped around and added back into the least significant bits. The final checksum is then the one's complement of this sum. When a receiver checks the checksum, it performs the same sum; if the result is zero, the packet is considered valid.
Why does the TCP header have a header length field and UDP header does not?
in tcp header (32 bits) we have a field that is called options and padding that has variable in length and the header length shows the actual header size i.e size of 20 octets+size of options and padding field and in UDP we dont have any field like that and its header is fixed of 8 OCTETS (32 bits header size) refrence: WIRELESS COMMUNICATIONS AND NETWORKS by William Stallings Second Edition pg 91(see fig)
What information is found in both the TCP and UDP header information?
souce and destination ports
