Answer / chandramohan dhaked

osi is a 7 layer model & it's difficult
tcp is a 4 layer model & it's much easy than osi model &
tcp model is fast dovleped than the osi model

Answer / nathan

OSI is a standard "reference model" that describes how
protocols should interact with one another. Invented by the
Department of Defense, TCP/IP became one of the "standards"
that enabled the Internet to become what it is today.
TCP/IP doesn't map cleanly into the OSI model.

OSI has seven layers and TCP/Ip has 4 layers.

Answer / ravi badesra

tcp/ip has 5 layes somewere somewere it is 4 layers and in
osi it has 7 layers tcp is the better model of understanding
internet protocols and transmission of data
it is much better then osi model

1.Both connectionless and connection-oriented communication
are supported in the network layer, but only
connection-oriented communication in the transport layer.
2.Seven layers, Network (Internet), Transport and
Application layers being similar to TCP/IP
3.Only four layers
4.Because models were invented before protocols,
functionalities put in each layer are not very optimized
5.In this case, the protocols have been invented before
models, so the functionalities are perfectly described
6.Service, interface and protocol are not clearly defined.
For example, the only real services offered by the Internet
layer are
- Send IP Packet
- Receive IP Packe
7.Protocols in the OSI model are better hidden and can be
replaced relatively easily as the technology changes, which
is one of the main objective of layered protocols

Answer / sonia

osi has both the session layer and the presentation layer
whatever tcp/ip combines both into an application layer.

Hi,

OSI is a Open System Internetworking and TCP Transmission
Control Protocol.

OSI consists of 7 layers and among these 7 layers once
these 7 layers are configured Transmission or data exchange
is possible.one can say TCP is Integrated with OSI .

in the ospf area network dr and bdr selection procedure occur let there are 4 router in that n/w r1 have the higher priority then r2 and r2 have higher priority then r3 and so on like that r1>r2>r3>r4 now as we know that selection of dr and bdr based upon the router priority so in this case r1 will be dr and r2 will be bdr now my question is that if i am going to implement 5th router which have greater priority then r1 then will it become dr atomically remember that i am not going change my 5 or 1st router property answer that one please
