3. OSI model & TCP/IP Suite.
 OSI model is a network model standardized
by ISO in 1970 to make networks more
flexible, robust and interoperable.
 TCP/IP Suite was developed as prior of OSI
model . It is a stack of protocols required for
communication.

4. TCP/IP and layers of OSI model.

5. TCP/IP and layers of OSI model.

6. TCP/IP protocols.
 Each layer in TCP/IP Suite is a set of protocols .
Let us see below_
 Application layer protocols: These are some
protocols come under application layer of TCP/IP
suite.
1. http (hyper text transfer protocol) - It is a protocol to
access data (plain, hypertext, audio, video etc.) on
the WWW.
2. ftp (file transfer protocol) – For copying a file from
one host to another.

7. TCP/IP protocols.
3. Smtp (simple mail transfer protocol) – It provides e mail
services to the users having email addresses on the
internet.
4. telnet (terminal network) – It provides remote access
services to the users on client server networks.

8. TCP/IP protocols.
 Transport layer protocols:
1. TCP (transmission control protocol): It provides a
reliable connection oriented support to transmit data
segments. All the segments follow the same
pathway in a sequence during transmission.
2. UDP (user datagram protocol): It provides
connection less support to transmit data in the form
of user datagrams. Here datagrams transmission is
path independent.
Note: These protocols also controls flow of data and
error during transmission.

9. TCP/IP protocols.
 Internet layer protocols:
1. IP (internet protocol): It provides path independent
transmission of IP- datagrams.
It is unreliable and doesn’t keep track of routes.
2. ARP (address resolution protocol): It associates logical
addresses to physical addresses.
3. RARP (reverse address resolution protocol): It
associates physical addresses to the concerned logical
addresses.
4. ICMP (internet control message protocol): For
specificaton of datagrams.
5: IGMP (internet group messase protocol): responsible
for simultaneous transmission of data in a group of
recipients.

10. TCP/IP protocols.
 Host to network layers don’t specify any special
protocol.
