A TCP protocol is oriented to the correct transmission of data, for this it makes a connection before sending data called ‘Three way handshake’ in which by means of three packets it makes a synchronisation and recognition between transmitter and receiver which ensures that the data path will be carried out, however this process will cause a considerable delay in the sending of data that can cause the receiver to listen to or receive data with a considerable delay and even with messages being mixed up.

However, UDP, despite skipping the connection stage and therefore ensuring a higher data transmission speed, also has the disadvantage of not guaranteeing that the data being sent will arrive correctly at its destination, which is necessary in the operation of real-time systems.
