Q 8
What is ARP and Write its working?
Answer
How ARP Works
When an incoming packet destined for a host machine on a particular local area network arrives at a gateway, the gateway asks the ARP program to find a physical host or MAC address that matches the IP address.
The ARP program looks in the ARP cache and, if it finds the address, provides it so that the packet can be converted to the right packet length and format and sent to the machine. If no entry is found for the IP address, ARP broadcasts a request packet in a special format to all the machines on the LAN to see if one machine knows that it has that IP address associated with it.
A machine that recognizes the IP address as its own returns a reply so indicating. ARP updates the ARP cache for future reference and then sends the packet to the MAC address that replied.
Q 9
Benefits of Disk Quota Management
Answer
Introduction
Disk quotas are a means of controlling the storage space available on a NTFS drive or partition. By setting quotas, an administrator can set the amount of information a user can store on that drive or partition.
An administrator can enforce limits on disk quotas, so that no user can exceed them. This means that, whenever a user exceeds its disk quota, he or she will not be able to store new data on it. Furthermore, the administrator can also set warning levels, so that they know beforehand when a user is getting close to its quota limit.

Q 8
What is ARP and Write its working?
Answer
- Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address that is recognized in the local network.
- For example, in IP Version 4, the most common level of IP in use today, an address is 32 bits long.
- A table, usually called the ARP cache, is used to maintain a correlation between each MAC address and its corresponding IP address.
- ARP provides the protocol rules for making this correlation and providing address conversion in both directions.
How ARP Works
When an incoming packet destined for a host machine on a particular local area network arrives at a gateway, the gateway asks the ARP program to find a physical host or MAC address that matches the IP address.
The ARP program looks in the ARP cache and, if it finds the address, provides it so that the packet can be converted to the right packet length and format and sent to the machine.
