Question

a) TCP/IP what is the name of the packets at the data link layer?

b) What are the two identifiers to locate a process in other part of the world so we can connect to it?

c) Supposed you are making a broadcast in your local network and the broadcasts reach a router . Would the router forward this broadcast message further or stop it? Why or why not?

d) Tcp/IP is the defacto network architecture for today's internet/ What does this mean?

Answer 1

a) data link link layer PDU is called FRAME

b) IP address : to identify the system

   Port number : to identify port to connect with the process

    

c ) The router will note forward the packet to outside of of local network .

                  In broadcasting Packets are fowarded to all outgoing link using Broadcast IP adderess. A router is used to connect two different networks. all packets transmitted to other network will be forwarded through router . But broadcast packet in local network will not be fowarded to other networks through router beacuse other Network's Broadcast IP address will be different.

d)

The (TCP/IP) is 4 layer architecure which has become the de-facto network architecture for today's internet over ISO/OSI architecure . Most companys / organizations use (TCP/IP) for netwrk communication. TCP/IP architecure have the network-communication protocols and application support protocols. TCP/IP architecure is in use before the ISO/OSI architecture .ISO/ OSI is a 7 layer Architecture . layers of ISO/OSI and TCP/IP can not be directly matched.infact ISO/OSI is elobarated form form of TCP/IP.
