tell me ten diffrence between Hub & Switch
tell me ten diffrence between Hub & Switch
1) ftp: file transfer protocol, that allows users to copy files between their local system and any system they can reach on the network.Originally Posted by mittra_ashish
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) ?
"2.router deside the path and send the message to the destination.
switch
can send the message only the given path .
Explain about MODEM commands?
how to connect router and bridge?
what is difference between socket &port?
how the port is applied in c language,java,or vb?
using c lanuage how will you connect socket using c,vb,java.
how will you implement datagram protocol and tcp in c lanuage ,vb,or java?
hi,
what is the peer to peer?
what is the y2k problem? my knowledge in cable problem but clarification?
with regards,

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
ans2: switch broadcast the signal. and router route the data packet in certain location.
ftp is file transfer protocol to upload files form ftp server and udp is user datagram protocol
tcp is transmission cantrol rotocol
udp is user datagram protocol
switch is used to connect a local area network i.e.network of a singal office.
router is used to connect two diffrent network i.e offices of diff citys
Re: Networking Questions
Hey... friends please answer this....
What is the differnce between A "Switch" and a "Hub"...
both can be used in LAN i think...
Is there any speed issue is concerning with these two when we talk about Data transfer....?
Please explain....

Re: Networking Questions
switch:-
1) switch works in the data link layer of osi model
2) Switch unicast the data
3) switch create mac table itself
4) switch have memory
5) switch contain one broadcast domain
6) switch contain multiple collision domain
7) switch contain all ports conect to the other ports with individual channel
8) switch one time broadcast to take mac address from connected all system with ports
HUB
1) hub works in the physical layer of osi model
2) hub broadcast the data
3) hub contain nothing any table
4) hub have not memory
5) hub contain one broadcast domain
6) hub contain one collision domain
7) hub contain one port are connect to next port with singal channel means on single channel all port transfer data to other port
switch is a layer 2 device .it supports full-duplex but hub doesn't ok
what is the difference between physical and logical address apart from that logical r computer generated and physical r by manufacturer...?
Re: Networking Questions
Physical address is your mac address.. it'll be given by manufacturer... its fixed.. you can change it using some software.. but after you restart your system the original mac will be set...
to retrieve your MAC address(physical address) type
getmac in dos-mode
Logical address comes into picture when you talk about virtual memory...
i.e a part of the secondary memory is used as ram... there we refer logical address rather physical..
Re: Networking Questions
logical address are that address that is asigned by user in the system like ip address
physical address are thataddress that is physically assigned by manufecturer like mac address. it is also known as physical address, mac address, ethernet address, hardware address. it is 48 bit size in 12 hexadecimal code that is divided into 24 bit 24 bit two part. first 24 bit is used for vendor and second 24 bit for unique addess.
mac address of any lan card manufectured by any company will not full match to other lan card manufectured by any company
The process of assigning the IP addresses by the DHCP server is also known as DORA (Discover, Offer, Request, and Acknowledgement).
