One of the features of TCP/IP Transport Layer is Multiplexing using ports.

When data is being transmitted, Data for more than one application can be sent, the receiving host chooses which application the data is destined for based on the port number.

Multiplexing also applies to User Datagram Protocol (UDP).

Multiplexing makes the data transfer more efficient and hence increases performance.
