UDP and how it works with Transport

What is UDP and how it helps the Transport layer in TCP/IP & OSI Model

What is UDP you ask? UDP stands for User Datagram Protocol and it mainly supports the internet/network layer of the TCP/IP model. UDP is a way for data to be organized and sent through the network. It is made up of single unit data grams that is first eight 8 bytes contained with its own id and the remaining bytes contain message data. The UDP data gram ID's was consist of 4 different classes.

• source port number
• checksum
• datagram size
• destination port number

Source Port- Basically allows access from a variety of different application to maintain a path for data to transfer; this works along with the Destination Port number.
Checksum- Secures data from being corrupted
Datagram Size- The total amount of memory (bytes) contained in the ID datagram.
