"Networking Protocol | Communication & Data Exchange | Presentation"

"This presentation covers the fundamentals of networking protocols, their role in data communication, and how they enable seamless connectivity. It explores key protocols like TCP/IP, HTTP, FTP, and DNS, highlighting their importance in modern networking."

1. Networking Protocol

2. Protocol Established set of rules that determine how data is transmitted between different devices in the same network

3. Human Protocol Communication LANGUAGE Speed and Timing Delivery Confirmation and Ackowledgment

4. Elements in Protocols Message Encoding Message Fomatting and Encapsulation Message Size Message Timing

5. TYPES Wireless Network Protocol WiFi Bluetooth LTE Internet Protocols TCP UDP HTTP SMTP FTP Network Routing Protocol EIGRP OSPF

6. HTTP TCP/IP based communication protocol Hypertext Transfer Protocol

7. Hypertext Transfer Protocol Basic Features client and server knows about each other during current request and response only Connectionless any type of data can be sent by HTTP as long as both the client and the server know how to handle the data content Media independent Server and client are aware of each other only during a current request. Afterwards, both of them forget about each other. Stateless

8. HTTP Protocol Web Client Web Server Serve Side Script Database The HTTP protocol is a request/response protocol based on the client/server based architecture where web browsers, robots and search engines, etc. act like HTTP clients, and the Web server acts as a server. Architecture

9. FTP provided by TCP/IP used for transmitting the files from one host to another. File Transfer Protocol

10. File Transfer Protocol Basic Features Out of band control cannot passes control data on the same connection as main data. Out of band the client establishes a Control Connection for the duration of an FTP session that typically spans multiple data transfers Stateful The client sends a request and waits for a response from the service. Synchronous

11. Working User Interface Control Process Data Transfer process Disk Disk Control Process Data Transfer Process TCP/IP Control Connection Data Connection File Transfer Protocol User

12. TCP rules and procedures that governs communications among computers on the internet Transmission Control Protocol

13. Transmission Control Protocol Features TCP keeps track of the segments being transmitted or being received by assigning numbers to each and every single one of them. Segment Numbering System Flow control limits the rate at which a sender transfers data. This is done to ensure reliable delivery. Flow Control TCP implements an error control mechanism for reliable data transfer Error Control TCP takes into account the level of congestion in the network Congestion Control

14. to make sure that each message reaches its target location intact, the TCP/IP model breaks down the data into small bundles and afterward reassembles the bundles into the original message on the opposite end. Working

15. UDP message-oriented communication protocol, used for communication channels and data paths. User Datagram Protocol

16. User Datagram Protocol Features Udp is faster then the TCP but not as relaiable Faster than TCP No acknowledgement is needed No acknowledgement Lower error control than TCP Error Control Unable to sequence Data sequence

17. Architecture UDP Header UDP Data Source port 16 bits Length 16 bits Destination port 16 bits Checksum 16 bits 8 Bytes

18. SMTP a standard protocol on a TCP/IP network for sending emails Simple Mail Transfer Protocol

19. Three Phases of Transfer handshaking (greeting) transfer of messages closure

20. Simple Mail Transfer Protocol Types The end-to-end model is used to communicate between different organizations End-to-end method the store and forward method is used within an organization Store-and- forward method

21. Working User agent User agent Message transfer agent Message transfer agent Queue User mailbox user user TCP Connection Server Receiver Sender

22. POP a point where many devices share a connection and can communicate with each other Post Office Protocol

23. Post Office Protocol Characteristics Post Office Protocol is an open protocol It allows access to new mail from a spread of client platform types. It supports download and delete functions even when offline. It requires no mail gateways due to its native nature. POP can handle email access only while the emails are sent by SMTP

24. Working Internet Sender Mail Server Recever Mail Server Sender Receiver SMTP SMTP POP
