1) State the size of MAC address both in Bytes and Bits.
MAC addresses are 12-digit (6 bytes or 48 bits).
2) Differentiate between IP and MAC address.

packets sent on a loopback address are re-routed back to the orginating node without any
alteration or modification.

ipconfig stands for Internet Protocol Configuration. This command is used to view all the
current TCP/IP network configurations values of the computer. It has to be taken under
consideration that ipconfig command displays both the enabled as well as the disabled
configurations of networking devices that are currently connected to the system.
ipconfig/all It gives the full configuration of the system.
7) What is Nslookup stands for? What is the significance of this utility? What
is Non-authoritative answer?
The name "nslookup" means "name server lookup". Non-authoritative name servers do not
contain original source files of domain’s zone. They have a cache file for the domains that is
constructed from all the DNS lookups done previously. If a DNS server responded for a DNS
query which doesn’t have original file is known as a Non-authoritative answer.
9) Write a command to find the remote computer user information.
The command is “ systeminfo “. Below the output of command.
