# System Configuration

Allow applications to access a device’s network configuration settings. Determine the reachability of the device, such as whether Wi-Fi or cell connectivity are active.

## Overview

Overview This collection of documents describes the programming interfaces of the System Configuration framework. The System Configuration framework provides functions that determine the reachability of target hosts in both a synchronous and an asynchronous manner. It also provides error detection facilities.
