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 do packets get to the right computer?
Each packet carries the address of the intended recipient. Each computer has a unique address. It works rather like the postal system.
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 .
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 do you get IP header of a UDP message?
Did you try Wireshark?
What has port numbers in its header?
both tcp and udp
A UDP header contains what fields?
A UDPheader contains four 16-bit fields. They are the source port, destination port, length, and checksum -- in that order.
The Protocol field used in IPV4 header is not present in the fixed IPV6 header Why not?
The Protocol field in the IPv4 header, which specifies the transport layer protocol used (like TCP or UDP), is not present in the fixed IPv6 header because IPv6 uses a more flexible approach with extension headers. Instead of a single Protocol field, IPv6 allows for multiple extension headers to be used, which can carry information about the transport protocol and other features. This design improves efficiency and scalability, enabling better handling of various protocols and options without cluttering the main header.
The fields in TCP header that are missing from UDP header?
The sequence number, acknowledge number, and Window fields.
Which is the correct order of headers from left to right in a completed frame?
UDP,Frame,IP
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
