Question

Which protocol makes a connection, checks whether the data is received, and resends it if it is not?

Answer 1

The TCP (Transmission Control Protocol) makes a connection and checks whether the data is received and resend it if it is not.

Before being sent between a server and a client, TCP organizes data. It guarantees the correctness of data sent through a network. Before transferring data, TCP establishes a connection between a source and destination and makes sure it is active until the data transmission begins.

Then, it splits massive amounts of data into smaller packets while always maintaining data integrity.
