AS ABOVW YOU SAW IT HAS 7 LAYERS
TCPIP HAS 4 LAYES
OSI HAS VERTICAL APPORACH
TCP IP HAS HORIZONTAL APPOROCH
OSI IS RELIABLE
TCPIP ISN'T
IT LAYERS USE ERROR CHCKING ,NIC PACKET
TRANSMISSSON,SEQUENCING,EMAILSERVERS
TCPIP IP CHEKS IP&PACKET IS TCP

Answer / lalitha
The main differences between the two models are as follows:
1.OSI is a reference model and TCP/IP is an implementation
of OSI model.
2.TCP/IP Protocols are considered to be standards around
which the internet has developed. The OSI model however is
a "generic, protocol-independent standard."
3.TCP/IP combines the presentation and session layer issues
into its application layer.
4.TCP/IP combines the OSI data link and physical layers into
the network access layer.
5.TCP/IP appears to be a simpler model and this is mainly
due to the fact that it has fewer layers.
6.TCP/IP is considered to be a more credible model- This is
mainly due to the fact because TCP/IP protocols are the
standards around which the internet was developed therefore
it mainly gains creditability due to this reason. Where as
in contrast networks are not usually built around the OSI
model as it is merely used as a guidance tool.
7.The OSI model consists of 7 architectural layers whereas
the TCP/IP only has 4 layers.
8.In the TCP/IP model of the Internet, protocols are
deliberately not as rigidly designed into strict layers as
the OSI model.[6] RFC 3439 contains a section entitled
"Layering considered harmful." However, TCP/IP does
recognize four broad layers of functionality which are
derived from the operating scope of their contained
protocols, namely the scope of the software application, the
end-to-end transport connection, the internetworking range,
and lastly the scope of the direct links to other nodes on
the local network.
9.The presumably strict consumer/producer layering of OSI as
it is usually described does not present contradictions in
TCP/IP, as it is permissible that protocol usage does not
follow the hierarchy implied in a layered model. Such
examples exist in some routing protocols (e.g., OSPF), or in
the description of tunneling protocols, which provide a Link
Layer for an application, although the tunnel host protocol
may well be a Transport or even an Application Layer
protocol in its own right.
10.The TCP/IP design generally favors decisions based on
simplicity, efficiency and ease of implementation.

Answer / gagandeep
1.Tcp Ip defined after tha advent of internet.Osi defined
before the advent of internet.
2.Tcp Ip support internet working.Osi does not supported
internet working.
3.Tcp ip model has 4 layers.the osi model has 7 layers.
4.the purpose of Tcp Ip is to connect multiple network and
tha purpose of Osi model is to show that how to faclitate a
communication between different computers without reqwiring
changes in the logic of h/w and s/w.
5.Tcp Ip is protocol dependent standard.Osi model is
protocol independent standard.

Answer / ankit dubey
1. OSI make clearly distinct between service,interface,protocol but TCP/IP does not.
2.OSI protocol are better hidden than TCP/IP.
3.In OSI model is invented before protocol so functionalities
are not perfectly described .
in TCP/IP protocol came first than model , so functionalities are perfectly described.
4.OSI has 7 layer while TCP/IP has only 4 layers.
5.In OSI network layer has both connectionless and connection oriented service but only connection oriented service in transport layer.
In TCP/IP network layer has connectionless service but support both modes in the transport layer.

Answer / giri
osi layer having seven layers , tcp, ip having only four
layers. osi stands for open system interconnect , tcp ip
stands for tranmission control protocal or internet protocal

Answer / deepak
Tcp/ip innovate in 1969
osi innovate in 1971
Tcp/ip in 4 layer Model
OSI is 7 Layer Model
TCP/ip works according to Socities
OSI works according to Layers
TCP/Ip has two ip Version(Ip Version 4 and 6)
OSI hasn't ip version

Answer / cath
1.OSI has both, the session layer and the presentation
layer, whereas TCP/IP combines both into an application
layer.
2.In the TCP/IP model of the Internet, protocols are
deliberately not as rigidly designed into strict layers as
the OSI model.
3.TCP/IP combines the presentation and session layer issues
into its application layer.
4.TCP/IP appears to be a more simpler model and this is
mainly due to the fact that it has fewer layers.

Answer / abhishek navale
osi doesnot support to the intenet.tcp/ip layer support to
the internet.osi model was 1st defined beore implementaion
takes place.tcp/ip model defined after protocol wee
immplementation.
