TCP/IP 模型和网络学科的 OSI 模型之间有很多相似之处。但是这里我们将讨论一些与 TCP/IP 相关的要点，如下所示。
OSI 模型：
开放系统互连简称OSI模型，它由7层组成，每一层都有一定的函数。这些是数据在到达目的地之前流动的层，基本上从底层开始，在数据通过网络从地球上的一个位置传输到另一个位置时在顶层结束。这些是存在于 OSI 网络模型中的层。
TCP/IP 模型：
传输控制协议简称为 TCP/IP 模型。它由4层组成，每一层都有一定的函数。这些是数据在到达目的地之前流动的层，基本上从底层开始，在数据通过网络从地球上的一个位置传输到另一个位置时在顶层结束。这些是存在于 TCP/IP 模型中的层。
TCP/IP 模型和 OSI 模型之间的相似之处：
以下是 TCP/IP 和 OSI 模型之间的相似之处。
| S.NO. | Similarities | TCP/IP and OSI Model |
|---|---|---|
| 1. | Model | Both TCP/IP are logical models. |
| 2. | Structure | Both are arranged as layered wise which is also called an architectural model. These models have a stack of protocols it means the protocol is arranged in every layer. Both the models have some set of protocols. |
| 3. | Networking | Both TCP/IP define standards for networking. |
| 4. | Framework | Both TCP/IP provide a framework for creating and implementing networking standards and devices. |
| 5. | Communication process | Both TCP/IP divide the network communication process into making their layers. |
| 6. | Similar components | In Both TCP/IP models manufacturer allows making sets devices and network components that can co-exist and work with the devices and components that are made by the other manufacturers. |
| 7. | functionality | In both TCP/IP models, a single layer defines a particular functionality and set standards for that functionality only. |
| 8. | Troubleshooting | Both the TCP/IP models simplifying their troubleshooting process by dividing the layer’s complex functions into simpler components of the layer. |
| 9. | Ethernet standards | Instead of defining the already defined standards and protocols in both the TCP/IP models. For example, the Ethernet standards were already defined by IEEE before proceeding to create these models. So instead of defining them again in both the models of IEEE Ethernet standards. |
结论 ：
在本节中，我们已经涵盖了 OSI 和 TCP/IP 模型的概述，并且您将能够理解计算机网络的 TCP/IP 和 OSI 模型的相似之处。
