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 way in which the PC is able to keep track of the data flow between multiple application sessions and have each application receive the correct packet flows is;

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

The way this works is that;

The source port number of an application is usually generated randomly and used to keep track of each session individually that are connected out to the Internet.

Now, each of the applications generated randomly will make use of their unique source port number through the internet to provide simultaneous communication as a result of multiple applications.

 With the tracking via source ports.

Explanation:

Hi, each application has a unique source port number randomly generated, it allows the pc to track the data flow.

Because of this a pc can send multiple HTTP service requests to a web server at the same time, and these requests can be tracked based on the source ports.

Feel free to ask for more if needed or if you did not understand something.
