# TCP-IP Networking Model

One of the types of [Network Model](https://app.gitbook.com/@mudassirs46/s/network-fundamentals/~/drafts/-MRZ4cjfS8UXyANv_uLC/internet-networking-model) is TCP-IP Networking Model.

* DOD (Department of Defense) took on the task to create the Second Open vendor-neutral Networking Model for Aiding the competition & Reducing the complexity of what would become known as TCP-IP (Transmission Control Protocol-Internet Protocol) Networking Model in 1974.
* Other Networking Model & including the OSI Networking model failed because of a slower formal standardization process & TCP/IP had become a common choice by the end of the 1990s.
* TCP-IP Model both Defines a large collection of protocols using the RFC & it also References them.
* The Vendors that create the Hardware (like Ethernet/WLAN Card) & Software (like OS) implemented TCP-IP due to which when we turn on any new PC anywhere in the world they all works flawlessly.
* TCP/IP Model (like all the other models) breaks the functions into small [TCP-IP Networking Layers](https://app.gitbook.com/@mudassirs46/s/network-fundamentals/~/drafts/-MRZ4cjfS8UXyANv_uLC/tcp-ip-layers) with each layer describing a category of functions that includes Standards & Protocols.&#x20;
