# TCP

After clicking on **TCP** in the **Plugins Module**, its options will show. All **TCP Communication** related components are encompassed by the **TCP Plugin**.

To refresh, **TCP**, or *Transmission Control Protocol*, is an integral form of data communication that is a part of the Internet protocol suite. More information can be found [here](https://en.wikipedia.org/wiki/Transmission_Control_Protocol). Within **Incari**, this is done by using the [**TCP Nodes**](https://docs.incari.com/incari-studio/2023.2/modules/plugins/communication/tcpconnectionsmanager) and connections are configured in the [**Project Settings**](https://docs.incari.com/incari-studio/2023.2/modules/project-settings/tcp-connection). They add the necessary functionality to a **Project** that requires this type of communication. However, the user may decide that they would rather deactivate this portion of **Incari** to heighten performance and stability.

To do this, the user needs simply to locate the toggle labeled `Activated` and click it once.

**Incari** will alert the user of this by outputting this message to the screen:

By following these instructions (save and restart **Incari Studio**) the user will deactivate the **TCP Plugin**.

Once the user has followed these steps, they will see that after restarting **Incari Studio** and going to the **Plugins Editor**, the checkmark by **TCP** will be gone and the toggle labeled `Deactivated`.

To activate again, the user just needs to repeat this by clicking `Deactivated` and saving and restarting again.
