Describe how ARP improves efficiency of MAC to IP address mappings?
ARP allows to get those mappings in the first place.

This is a peer-to-peer network, where all devices in the workgroup have equal status. In this model there is no central management of the network (or any network management at all).
The short answer is no, your internet does not still work. Now, it depends on what you are asking. There are many things that could be considered sleep mode. It could be that the screen saver kicked on in which case, everything in the background is still working and the answere would be YES. However, if you are in standby, your monitor and hard drive have stopped and in hibernation, you system has saved a snapshot of what you were doing and powered down.
>All application such as browser will be minimize after you put it "sleep" mode. Maybe, you mean with the screen saver I will say "yes" because only your monitor sleep (standby) not the entire Central Processing Unit (CPU). Meaning your Internet connection stop, the moment you put it to "sleep" or "hibernate" mode.
The rest of the frames will be held in the incoming queue until the first frame is served.
Which command excludes seven host addresses from a DHCP pool that has a 255.255.255.192 mask?
A. router(config)#ip dhcp excluded-address 192.168.7.0 192.168.7.6
B.router(config)#ip dhcp excluded-address 192.168.7.121 192.168.7.127
C.router(config)#ip dhcp excluded-address 192.168.7.159 192.168.7.165
D.router(config)#ip dhcp excluded-address 192.168.7.193 192.168.7.198
Answer A: cannot provide network address to host(192.168.7.0) so answer A is incorrect.
Answer B: address 192.168.7.127 is broadcast address so it cannot be given to a host.
Answer C: is correct. IP address 192.168.7.159 falls in network 192.168.7.128 which is valid and .159-.165 gives you seven IP addresses.
Answer D: IP address 192.168.7.193- 192.168.7.198 gives you six IP addresses and you need to exclude seven, so answer D is incorrect.
IP TCP and UDP all discard a packet that arrives with a checksum error and do not?
Only TCP will automatically discard a packet with a bad checksum. UDP packets have a checksum field, but it is rarely used, and then only by the application (not UDP itself)

How is p2p different from a peer to peer network?
It isn't peer to peer and P2P refer to the same thing.
Use BgInfo on each computer and the desktop will display the computer name or lots of other configurable information. Here is a link to it. http://technet.microsoft.com/en-us/sysinternals/bb897557.aspx
peer checking is much like desk checking in that it is simply another way to test if your program or algorithms are correct and accurtate and function as they should. desk checking is when you personally test your program using sample test data. peer checking is when other individuals other than yourself test your program using different test data.
Use 2 bits to determine the subnet mask to make the host range?
If you are borrowing 2 bits, then the subnet masks will look like:
255.192.0.0 Class A
255.255.192.0 Class B
255.255.255.192 Class C
What is several network layer models proposed in the OSI model?
Suggest you go to a search engine and look for OSI seven layer model
What id the role of iana in ip address?
The IANA organization was originally responsible for registering an IP address for an organization, and also handling domain name requests, and so forth.
IANA is now part of ICANN, which oversees these areas and others within the Internet.
One no longer has to register directly via IANA (which used to be the only way to get an IP address for your network in the past). You can register via other domain registrars and ISP organizations, which do the work for you.
Only the Network Layer (Layer 3) portion of the datagram is used by the Network Layer (Layer 3) portion of the TCP/IP Model.
The network portion of the datagram includes IP Addressing information, and things such as TTL (Time to Live), and Datagram Priority markings.
as we know the protocol is collection of rules and regulation.while every communication takes place there is a protocol.protocol states whwt is format of data ,how much time to given.

When a LAN world is created, you can find the world in the 'multiplayer' section in the main menu. Double click on the selected LAN world to connect to the world. Remember that you have to be on the same Wi-Fi as the person you are trying to connect with.
