What is the need of MAC address if we have HID to identify a host??

MAC address is the permanent address where as ip address is static.Your ip changes after some time at that time we check the MAC address from the router and see the present ip address of that system and we send the data to that system.

public IP's efficiently utilize with the help of private IP's 

like that college campus uses public IP with privates IP's.

 in the lecture (video of subnetting )  you explain about  subnet masking there you told the Subnet Mask calculation that Point was wrong please make it correct.. In Subnet Mask all the network ID and subnet bits all should  1's and all host bits should be 0's. for example 255.255.255.128 is the Subnet Mask for network 200.1.1.1_ _ _ _ _ _ _ all left bits are host bits..

@shraddhagami that means they will receive also with different ports. but they are receiving a webpage sent through http protocol only and http application protocol is at port 80..

@dashish

Server opens a socket that 'listens' at port 80 and 'accepts' new connections from that socket. Each new connection is represented by a new socket whose local port is also port 80, but whose remote ip:port is as per the client who connected. All process use different source port number so they differentiate two process.

Correct me If i m wrong.
