Networking Knowledgebase

Introduction

Understanding TCP/IP is fundamental to networking. This knowledgebase provides essential information for grasping the core principles.

TCP/IP Fundamentals

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.

Key Concepts

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.

Example: A simple TCP/IP connection

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.

Request Handling

The current page is requesting information about TCP/IP. We will process the request and return a response.

Example of a Response

Server:

TCP/IP Connection Established.

User:

The user has successfully connected to the network. You can proceed with your requests.
