TCPIP Model of Networking TCPIP Model Layers Application

TCP/IP Model of Networking

TCP/IP Model - Layers Application Transport Internet Access

TCP/IP and Protocols Application Layer HTTP, HTTPS FTP, TFTP DHCP, DNS POP 3, SMTP, IMAP

TCP/IP and Protocols Transport Layer TCP UDP

TCP/IP and Protocols Internet Layer IP ICMP

TCP/IP and Protocols Access Layer Ethernet Wi. Fi Point to Point

TCP/IP and Functions Application Layer Data is created and used Client and/or Server Software

Client Server Networks

TCP/IP and Functions Transport Layer TCP – 3 Way Handshake UDP – Request, Send

3 Way Handshake Request Rules y m e r a HKe, re. Here are my Rules OK, O OK, Fine Data

TCP/IP and Functions Internet Layer IP - Addressing of Nodes IP – Best Path Delivery ICMP – Diagnostic and ID

TCP/IP and Functions Access Layer Local Delivery

TCP/IP and Encapsulation Application Layer Produces Data Encryption, Compression

TCP/IP and Encapsulation Transport Layer Segments Data Port Numbers Added

Well Know Port Numbers Application Port Number FTP 20, 21 Telnet 23 SMTP 25 DNS 53 TFTP 69 HTTP 80 HTTPS 443 DHCP 546, 547

TCP/IP and Encapsulation Internet Layer Adds IP Addresses Now called a Packet

Socket IP Address: Port Number Or URL: Port Number https: //10. 140. 100. 63: 5009

TCP/IP and Encapsulation Access Layer Adds MAC Address for local delivery Now called a Frame

TCP/IP and Dencapsulation Access Layer Reads MAC Address Checks for Errors Should I read it?

TCP/IP and Decapsulation Internet Layer Reads IP Address Should I read it?

TCP/IP and Decapsulation Transport Layer Reads Port Number TCP – Put message together Which App should I send it to?

TCP/IP and Decapsulation Application Layer Uses Data
