What is TCP and UDP?

What is TCP and UDP?

TCP stands for Transmission Control Protocol. It is a type of method used by computer to send data from a computer to another computer. With this method, two computer can guarantee the data arrived safely and correctly. This type of transferring data tends to be quicker but puts a high load on the computer as it has to monitor the connection and the data going across.

UDP stands for User Datagram Protocol. The computer normally use this type of method to send data packages with hopes that other side will get the data. UDP does not connect directly to the receiving computer like TCP does, but rather sends the data out and relies on the devices in between the sending computer and receiving computer to get the data by itself. By using this type of transmission, it is not guarantee that the data will reach its destination. On the other hand, this method has a very low overhead and it is very useful for services that are not that important to work on.
