There are two key characteristics that are shared by TCP and UDP: they are both transport layer protocols, and they are both connectionless protocols.
As transport layer protocols, TCP and UDP provide a way for data to be transferred between two points on a network. TCP is a reliable protocol, meaning that it ensures that data is delivered in the order in which it was sent. UDP is an unreliable protocol, meaning that data may be lost or delivered out of order.
Both TCP and UDP are connectionless protocols, which means that they do not require a connection to be established before data can be transferred. This allows for data to be transferred quickly and without overhead.
How do TCP and UDP differ in terms of flow control?
TCP and UDP differ in their approach to flow control. TCP uses awindow-based flow control scheme, which allows it to control the rate atwhich data is sent. UDP, on the other hand, does not use a flow controlscheme. This means that UDP is able to send data at a much higher rate,but it is also more likely to drop packets.
Frequently Asked Questions
What is the difference between UDP and TCP?
UDP is a connection-oriented protocol, while TCP is a connectionless protocol. UDP messages contain packets that were sent one by one, while TCP reads data as streams of bytes and transmits the message to segment boundaries.
What is TCP/UDP sequencing?
TCP sequencing means that the data packets arrive in the intended order at the receiver’s end. Sequencing of data does not occur in UDP.
Why do tcp and UDP use source and destination port numbers?
TCP and UDP use source and destination port numbers to distinguish different data streams and to forward the right data segments to the right applications. Using a check sum calculation, they can determine if the data is corrupted (has errors).
What is the header size of UDP and TCP?
UDP header size is 8 bytes, while TCP header size is more than double at 20 bytes.
What is TCP/UDP?
TCP is "transmission control protocol" while UDP is the "datagram protocol." TCP provides reliable, ordered delivery of data streams between applications on a network. TCP guarantees that packets will be delivered in the same order they were sent. UDP assigns no such guarantee; it is sometimes called a unreliable protocol.
