4. Introduction
 Computers use network protocols to communicate
in computer networks. There are many network
protocols in existence; TCP/IP are the family of
network protocols that are used for the Internet.
 A network protocol is a standard written down on
a piece of paper [or, more precisely , with a text
editor in a computer]. The standards that are
used for the Internet are called Request For
Comment[RFC]

5. HISTORY
 The internet base protocols and system were
mainly devised in the 1970s and 1980s.
 TCP/IP describes a protocol which will work on
any source of computer and operating system
for transportation of data across the internet
between different systems.
 TCP/IP has proven to be remarkably robust,
but is very basic.

6. What are network protocols
 The word protocols comes form the Greek
protocollon , meaning a leaf of paper glued to a
manuscript volume that describes the contents.
 Network protocol is a set of rules that governs the
communications between computers on a network.
Network protocols are formal standards and policies
comprised of rules, procedures and formats that
define communication between two or more devices
over a network.
 Network protocols govern the end-to-end processes of
timely, secure and managed data or network
communication.

7. Requirements of Protocols
 Data formats for data exchange.
 Flow control.
 Routing.
 Acknowledgements.
 Loss of information.
 Sequence control.

8. Protocol Functions
 Identifies errors.
 Applies compression techniques.
 Decides on:
How to announce sent data
How to announce receive data
How to address data
How data is to be sent

9. Need of Protocols
 Protocols are needed for predetermined
understandings for communications.
 It helps the smooth functioning of a system,
such contribution to a system may benefit or
offend you from where you stand.

10. Types of Protocol
 TCP: Transmission Control Protocol
 HTTP: Hypertext Transfer Protocol
 FTP: File Transfer Protocol
 SMTP: Simple Mail Transfer Protocol
 UDPL: User Datagram Protocol
 ICMP: Internet Control Message Protocol
 SCTP: Stream Control Transmission Protocol
 ARP: Address Resolution Protocol

11. TCP/IP Protocols
 TCP/IP:
TCP/IP is a set of rules [protocols] governing
communications among all computes on the internet.
TCP/IP was developed in 1978 and driven by Bob Kahn
and Vint Cerf.
TCP/IP is a combination of two separate protocols:
Transmission Control Protocol [TCP] and Internet
Protocol [IP].
The Transmission control Protocol is responsible for
ensuring the reliable transmission of data across
Internet-connected networks.
TCP checks packets for errors and submits requests for
re-transmissions if any are found.

12. HTTP Protocol
 HTTP:
The Hypertext Transfer Protocol [HTTP] is an
application protocol for
distributed ,collaborative , hypermedia
information systems . HTTP is the foundation of
data communication for the World Wide Web.
Development of HTTP was initiated by Tim
Berners-Lee at CERN in 1989.
HTTP is an application layer protocol designed
within the framework of the Internet protocol
suite.

13. FTP Protocol
 FTP:
File Transfer Protocol [FTP] is a standard
Internet protocol for transmitting files between
computers on the Internet over TCP/IP connections.
FTP is a client-server protocol that relies on two
communications channels between client and
server: a command channel for controlling the
conversation and a data channel for transmitting
file content.

14. SMTP and UDP
 SMTP:
Simple Mail Transfer Protocol is used to transport
mail. Simple Mail Transport Protocol is used on the
internet, it is not a transport layer protocol but is an
application layer protocol.
 UDP:
An unreliable connection less protocol used to
control the management of application level services
between computers. It is used for transport by some
applications which must provide their own reliability.

15. ICMP and ARP
 ICMP:
Internet control message protocol provides
management and error reporting to help manage
the process of sending data between computers.
[Management].
 ARP:
Address Resolution Protocol enables the
packaging of IP data into Ethernet packages. It is
the system and messaging protocol that is used to
find the ethernet [hardware] address from a
specific IP number.

16. POP Protocol
 POP:
POP stands for Post Office Protocol. It is
generally used to support a single client. There
are several versions of POP but the POP 3 is the
current standard.
POP is an application layer internet standard
protocol.
POP does not allow search facility. It is not
suitable for accessing non mail data.

17. Benefits Of Network Protocols
 Some important benefits are;
 They provide the path t increase the network
connections.
 Enhance the speed of the connection.
 Enhance the data transmission rate and
provide easy working to the users.

18. Conclusion
 Computer Networks and Protocols have forever
Changed the way humans will work, play, and
communicate.
 New protocols and standards will emerge, new
applications will be conceived and our lives
will be further changed and enhanced.
