List and describe the three categories that tcp/ip divides port numbers into.

The TCP/IP protocol suite maps to a four-layer conceptual model known as the DARPA model, which was named after the U.S. government agency that initially developed TCP/IP. The four layers of the DARPA model are: Application, Transport, Internet, and Network Interface.

Your answer would be, The three categories that TCP/IP divides port numbers into, Well-known port numbers (0-1023). Reserved for the most universal applications; Registered port numbers (1024-49151). Other applications that are not as widely used; Dynamic and private port numbers (49152 - 65535). Available for use by any application.

Hope that helps :)

is this question from a book? ?
