A technician with a PC is using multiple applications while connected to the Internet. How is the PC able to keep track of the data flow between multiple application sessions and have each application receive the correct packet flows

The data flow is being tracked based on the source port number utilized by each application

Explanation:

Every application has a source port number which is usually generated randomly and used for the purpose of keeping track of every session of connection to the internet on an individual basis. In this way, each application is required to use a source code unique to an application to provide concurrent communication from a number of applications via the internet.
