Simplelink WiFi enabled boards can use the WiFi library to connect to the internet. It can serve as either a server accepting incoming connections or a client making outgoing ones. The library supports WEP and WPA2 Personal encryption, but not WPA2 Enterprise. Supported Devices: CC3100, CC3200 Energia communicates with the WiFi network processor using the SPI bus. The WiFi library is very similar to the [Ethernet](http://energia.nu/reference/ethernet/ "Ethernet") library, and many of the function calls are the same. For additional information on Simplink WiFi, visit the support page from TI: [Embedded WiFi ](http://www.ti.com/lsds/ti/wireless_connectivity/embedded_wi-fi/overview.page)
The WiFi class initializes the ethernet library and network settings.
The IPAddress class provides information about the network configuration.
The Server class creates servers which can send data to and receive data from connected clients (programs running on other computers or devices).
The client class creates clients that can connect to servers and send and receive data.
The UDP class enables UDP message to be sent and received.
