TCP_IP_Model_Presentation for Network communication
- 1. TCP/IP Model • AnOverview of the Transmission Control Protocol/Internet Protocol
- 2. Introduction • TCP/IP isthe foundational communication protocol suite for the internet. • It enables reliable data transmission between devices over networks.
- 3. History • Developed byDARPA in the 1970s. • Adopted as the standard protocol for ARPANET in 1983. • Became the foundation of the modern internet.
- 4. Layer Overview • TCP/IPmodel has 4 layers: • 1. Network Interface • 2. Internet • 3. Transport • 4. Application
- 5. Network Interface Layer •Responsible for physical transmission of data. • Includes hardware and device drivers. • Examples: Ethernet, Wi-Fi.
- 6. Internet Layer • Handleslogical addressing and routing. • Key protocol: Internet Protocol (IP). • Other protocols: ICMP, ARP.
- 7. Transport Layer • Ensuresreliable data transfer. • Key protocols: TCP (reliable), UDP (unreliable). • Manages flow control and error checking.
- 8. Application Layer • Providesnetwork services to end-users. • Examples: HTTP, FTP, SMTP, DNS. • Interfaces with software applications.
- 9. Comparison with OSIModel • OSI has 7 layers; TCP/IP has 4 layers. • TCP/IP combines OSI's Application, Presentation, and Session layers into one. • More practical and widely used than OSI.
- 10. Real-world Examples • Webbrowsing using HTTP over TCP/IP. • Email transmission via SMTP. • Streaming media using UDP.
- 11. Conclusion • TCP/IP isessential for modern networking. • Its layered architecture ensures interoperability. • Continues to evolve with internet technologies.
