To help determine to which application a transmission should be delivered on a particular computer,TCP uses the application layer port addresses to distinguish among many open applications on a computer

Explain how TCP/IP works in a high level way,using a detailed diagram including the different roles of TCP vs.IP,and the times at which each function is utilized in the process.

Under what conditions does decentralized dynamic routing provide better performance than decentralized static routing?

Translating an application layer address to a network layer address and finally to a data link layer address is called address resolution.

A multicast message can be used to send a message to a maximum of two other computers.

When TCP/IP translates a network layer address into a data link layer address,it sends a special ____________ to all computers in the subnet.

IPv6 is based upon _________ -byte addresses.

Source port address is the logical address generated by the application layer on the source computer to identify the application,which is sending the data.
