2. What Is Network Protocol
A protocols is a set of rules for the exchange of data
between a terminal and computer or between two
computer.
A protocol is a set of rules or agreed upon guidelines for
communication. When communicating it is important to
agree on how to do so. If one party speaks French and one
German the communications will most likely fail. If they
both agree on a single language communications will work.

3. Types Of Network Protocols
• Network routing protocols
• Internet protocols
• Wireless network protocols

4. Network Routing Protocols
A routing protocol uses software and routing algorithms to
determine optimal network data transfer and communication paths
between network nodes. Routing protocols facilitate router
communication and overall network topology understanding. There
are three major types of routing protocols.
1. Enhanced interior gateway routing protocol (EIGRP)
2. Open Shortest Path First (OSPF)
3. Border Gateway Protocol (BGP)

5. 1. Enhanced interior gateway routing protocol (EIGRP)
EIGRP is an advanced distance-vector routing protocol that is used on a
computer network for automating routing decisions and configuration. The
protocol was designed by Cisco Systems as a proprietary protocol, available
only on Cisco routers. Functionality of EIGRP was converted to an open
standard in 2013 and was published with informational status as RFC 7868
in 2016.
2. Open Shortest Path First (OSPF)
OSPF is a routing protocol for Internet Protocol (IP) networks. It uses a link
state routing (LSR) algorithm and falls into the group of interior gateway
protocols (IGPs), operating within a single autonomous system (AS). It is
defined as OSPF Version 2 in RFC 2328 (1998) for IPv4.[1] The updates for
IPv6 are specified as OSPF Version 3 in RFC 5340 (2008). OSPF supports
the Classless Inter-Domain Routing (CIDR) addressing model. OSPF is a
widely used IGP in large enterprise networks.

6. 3. Border Gateway Protocol (BGP)
• Routing protocol
• Exterior routing protocol
• Routing between AS
• Routing protocol of internet

7. Internet protocols (IP)
The Internet Protocol (IP) is the principal communications protocol
in the Internet protocol suite for relaying datagrams across network
boundaries. Its routing function enables internetworking, and
essentially establishes the Internet.
IP has the task of delivering packets from the source host to the
destination host solely based on the IP addresses in the packet
headers. For this purpose, IP defines packet structures that
encapsulate the data to be delivered. It also defines addressing
methods that are used to label the datagram with source and
destination information.

8. 1. User Datagram Protocol (UDP)
UDP is a connectionless and
unreliable transport protocol.The
two ports serve to identify the end
points within the source and
destination machines. User
Datagram Protocol is used, in place
of TCP, when a reliable delivery is
not required. However, UDP is
never used to send important data
such as web-pages, database
information, etc. Streaming media
such as video, audio and others
use UDP because it offers speed.

9. 2. Transmission Control Protocol
(TCP)
Abbreviation of Transmission
Control Protocol, and
pronounced as separate letters.
TCP is one of the main protocols
in TCP/IP networks. Whereas
the IP protocol deals only with
packets, TCP enables two hosts
to establish a connection and
exchange streams of data. TCP
guarantees delivery of data and
also guarantees that packets
will be delivered in the same
order in which they were sent.

10. 3. File Transfer Protocol (FTP)
• Tt is used to exchange files
on internet.
• FTP is most commenly
used to upload & download
the files from the internet.
• FTP also allow to update
(delet,renew,move and
copy) files at a server.
• it use the port 21.

11. Hypertext Transfer Protocol (HTTP)
• used to access data on
www.
• HTTP is a combination of
FTP & SMTP.
• HTTP massages are
delivered immediately.
• HTTP is the services of
TCP on the port 80.

12. Hypertext Transfer Protocol
Secure (HTTPS)
• HTTPS also work like
HTTP .
• It is more secure than
HTTP
• For security it work with
SSL(secure socket layer)
• HTTPS = HTTP + SSL

13. Wireless Network Protocols
Wireless protocols and technology are constantly changing --
increasingly affecting how we communicate. Wireless deployments
are currently just one of many parts of an enterprise's network. As
the protocols and technologies change, if current predictions come
true, wireless could eventually replace wired networks completely.
1. WIFI
2. Bluetooth

14. 1. Wireless Fidelity System (WIFI)
• WIFI is the standard for the
high wireless LAN.
• Developed in 1997 by IEEE
named 802.11 speed of 2mbps.
• In 1999 802.11a (commercial)
at 54mbps & 802.11b at
11mbps (domestic)
• In 2003 802.11g (2.4GHz at
54mbps)
• In 2009 802.11n up to
600mbps
• In 2013 802.11ac at 1.3gbps
(5GHz)

15. 2. Bluetooth
• Developed by Ericson in
1994.
• It provides a way to
connect & exchange info
between devices.
• It works on radio frequency
(2.4GHz-2.485GHz).
• It is designed for low
power consumption with a
short range.
• Can connect up to 8 devices
1 master + 7 slave.
