Question

Both UDP and TCP use port numbers to identify the destination entity when delivering a message. Give at least one reason for why these protocols invented a new abstract ID (port number), instead of using process IDs, which already existed when these protocols are designed.

Answer 1

Follows are the solution to this question:

Step-by-step explanation:

The process ID is not static because this can't be used to identity, therefore, it includes excellent service providers like HTTP since it is allocated dynamically only to process whenever a process is initiated.

Sometimes its instance connectors are managed on numerous TSAPs. This can be implemented unless the process ID is being used as each procedure could have an identity.
