Introduction to TCP/IP - Class 101 HD

#Buy TCP/IP: http://amzn.to/1T69RS3 If You Want to Learn the TCP/IP Protocol than You Need Understand the Fundelmental of TCP/IP. #1. Introduction to TCP/IP# So the TCP Stand for "Transmission Control Protocol" and IP Mean "Internet Protocol". TCP is First Networking Protocols to Define Networking Standard. The Internet Runs on the Top of TCP/IP and World Wide Web Runs on the Top of Internet. All the Major Web Applications Such as eMail, Remote Desktop, FTP, etc Run on the TCP/IP Stack. --1. IP is Responsibility is Moving Data Packets from Node to Node. Node is a Connection point, a Redistribution point, or a Communication Endpoint. The Real Meaning of Node depends on Network Layer and Protocol Layer. -- 1. Physical Node is Electronic Device Which is Attached to the Network. --2. TCP is Responsibility is to Verify Delivery of Data from Client to Server. Because Data Can Be Lost So the TCP Add Errors or Data Lost Support and It Resend the Data Until the Data is Correctly Recived. #2. TCP/IP Protocol Stack Before I Start Talking about the TCP/IP Stack, I Want to Talk about OSI Model. So the OSI Model Stand for Open Systems Interconnection Which Standardizes the Communication Functions of a Telecommunication and Computers. OSI Protocol Stack 7. Application -- Applications Such as Web,FTP and eMail. 6. Presentation -- Data Compression and Encryption/Decryption. 5. Session -- Authenication and authorization 4. Transport -- Reliable Transmission and Gaurentee Delivery of Packets 3. Network -- Packet Routing and Traffic Control 2. Data Link -- Transmit and Receive Packets Physical layer 1. Physical -- The Physical Cable and Connection itself. TCP/IP Protocol Stack. 5. Application -- Authenication and Compression. 4. Transport -- Handles and Splitis the Data into Smaller Chunks and Adds Ports Information. 3. Network -- Packet Routing and Adds IP Address on Where the Data is Going and from. 2. Link -- Add MAC Address to Identity Where the Data is Coming from. MAC Address is a Physical Address Communications on Physical Network. TCP/IP VS OSI: Layer 5,6 and 7 of OSI is Handle By TCP/IP Application Layer. TCP/IP Transport Layer Do Not 100% Guarantee the Packet Had Been Deliver as the Transport Layer of OSI. #3. IP Address So the IP Address is Assign to Each Device Who is on the Network Which Use the Internet Protocol for Communication. IP Address Have 2 Functions: 1. Host 2. Network Interface Identification and Location Addressing Today We are Using IPv4 Which is a 32 Bit Address But Also We Have IPv6 Which is 128 Bits Address. IPv4 Address is Such as 192.12.252.1. IPv6 Address 2001:db4:0:1534:0:637:0:1 The IPv4 Address Can Be from 0 to 255 and When you are in an Isolated Netwrok than Your IP Address us Unquie. Static Vs Dynamic IP Addresses: So We IP Address Can Static Which Never Change and Good for Printer and Dynaimic IP Address Which Change Everyone time You Connect to the Net
