1) ftp: file transfer protocol, that allows users to copy files between their local system and any system they can reach on the network.
udp: user datagram protocol.
2) switch it is an data link device, it works with physical adress. it has 1 broadcast domain & number of collision domains.
router is a network layer device, it works with logical adress & fixed band width. it connects two or more different domains.
3) DORA is a process to give a ip automatically to client
D-discover, the client system discover the server in the domain
O-offer, server offer an pool of ip adressess
R-request, from the pool of adress client select one of the request
A-acknowledgement, selected request of client was confirmed by the server by sending acknowledgment.
4) ?

dear friend,

FTP . file transfer protocols, which is used to send a bulk data. not only send u can receive also. if u want get the data from u r ftp server(placed in u r org.,) u should know the ip address of the ftp server. so that u can contact u r ftp server from anywhere else. the ftp it uses port number 20 and 21 in the application layer, it uses tcp protocol in the transport layer.

UDP : user datagram protocol, it is a connectionless protocols in the transport layer of the OSI model. it is very fast, so that u can send voice, video.

DORA: Discover, Offer, Request,Acknowledgement

when the client need a ip address from the dhcp server. at first the client , it has to find out who is the dhcp server in our network isn't it for that it send discover pkt., (That means where is the dhcp server located).

Once the client Discover the server, than the server it will give the Request to that particular client , as (with the help of mac address of that particular client) i will offer this particular ip ( it is giving offer only so the client weather may it will accept or not).

once the client accept that praticular which it has received from the server , than the client it will give the request as ok server sir i will use that particular ip.

for that particular rqst the server it will give tha Acknowledgement ok client sir u got the ip from me. that's all

the dhcp it uses two port number one is udp-67 for server, another one is udp-68 for the client
