Domain of Internet of Things \"IoT\" aims the human by the smart resolutions via Machine-to-Machine \"M2M\" connection in whole of world, efficiently. This was hard for ignoring internet of things domain importance field by novel applications deployment like the smartphone in current age. Most important layer in \"IoT\" architecture of internet of things isthe layer of network, due to the different systems (gateway, perform of cloud computing, switching, hub and so on), different technologies of connection (WiFi , Bluetooth, Long-Term Evolution (LTE), and so on) united in the layer. Layers of network must transfer information to / from the various applications /objects, via gateways / interfaces between the networks which are heterogeneous, also utilizing different technologies of connection, protocols. The current study highlighted the state-of-the-art of \"IoT\" technologies used in the \"IoT\" architectures and the variations between them in addition to their applications in life.
