# [Android Components](../../../README.md) > Browser > State

The `browser-state` component is responsible for maintaining the centralized state of a [browser engine](../../concept/engine/README.md).

The immutable `BrowserState` can be accessed and observed via the `BrowserStore`. Apps and other components can dispatch `Action`s on the store in order to trigger the creation of a new `BrowserState`.

Patterns and concepts this component uses are heavily inspired by Redux. Therefore the [Redux documentation](https://redux.js.org/introduction/getting-started) is an excellent resource for learning about some of those concepts.
