Understanding TCP/IP is fundamental to networking. This knowledgebase provides essential information for grasping the core principles.
TCP/IP is the foundation of modern networking. It defines how data is transmitted between devices over a network. Key protocols include TCP (Transmission Control Protocol) for reliable data transfer and UDP (User Datagram Protocol) for faster, less reliable data transmission.
IP Addressing: Each device on a network has a unique IP address. The network address is the first 30 bits, and the host address is the last 30 bits. Routing: IP packets are routed from source to destination using routing tables.
DNS: Domain Name System translates human-readable domain names (like www.google.com) into IP addresses.
Let's illustrate a basic TCP/IP connection. Imagine a user connects to a web server:
User sends a request to 192.168.1.10. The server receives the request and replies with a response.
This process involves establishing a connection, transmitting data, and establishing a complete communication cycle.
The current page is requesting information about TCP/IP. We will process the request and return a response.
Server:
User:
The user has successfully connected to the network. You can proceed with your requests.
