Answer:
The Push flag
Step-by-step explanation:
When sending a very small amount of information which the listening program needs to respond to immediately. The Transmission Control Protocol (TCP) flag that will be used is the Push flag.
The Push flag, like the Urgent flag, was brought into existence to ensure that the data is given the priority it deserves and it is urgently processed at the sending or receiving end. Push flag is used more often at the beginning and end of a data transfer, it affect the way the data is handled at both ends (sending and receiving).
When developers make available new applications, they must always ensure they follow specific guidelines given by the RFC's to ensure that the applications created work properly / efficiently and control the flow of data in and out of the application layer of the OSI model perfectly. When used, the Push bit ensure that the data segment is handled correctly and given the deserved priority at both ends of a virtual connection.
