The "ARP" stands for Address Resolution Protocol. The ARP
standard defines two basic message types: a request and a
response. a request message contains an IP address and
requests the corresponding hardware address; a replay
contains both the IP address, sent in the request, and the
hardware address.

The previous answers are sufficient enough for this
question especially Answer 1 ,but a more precise and
detailed answer [if needed] is added here
ARP is used to map a destination IP address to its MAC
address.An ARP request when added to a IP datagram has the
following fields to it [Note that a ARP request packet is
added to the IP datagram in the DATA Field]...
1) Hardware Type [Ethernet/Token Ring .. Details]
2) Protocol Type [IP/IPX ..details]
3) Operation field
[ARP Req,ARP reply,Proxy ARF Req,Proxy ARP Reply]
4) H/w Length
5) Protocol Length
6) Source IP
7) Source MAC addr
8) Destination IP
9) Destination MAC addr
Here the main focus will be on the fields 6-9 ..
6) Source IP [needs no explanation]
7) Source MAC addr [needs no explanation]
8) Destination IP [needs no explanation]
9) Destination MAC addr [This will be 0000:0000:0000]
So,how do we say a ARP request is broadcasted ?
Yes,it is broadcasted ... The reason is that,the
Destination MAC address at Layer 2 will be FFFF:FFFF:FFFF
whereas the Destination MAC on a ARP Packet will be 0000:
0000:0000 which is encapsulated as a payload in a datagram.
On receving this ARP request the Destination will fill its
own MAC address in place of all 0's and send it back to the
source as ARP reply.

Answer / priyanka
ARP is jst finding the mac address when the ip address is known of a host.ARP basically needs to be find out when NIC (network interface card) is not present in host as we know that mac address is present on it. So it is the reason of finding the mac address.
