It still retains the plug-and-play simplicity which has made it popular.

Alexa is supported by an array of in-built microphones which can capture sounds, including your voice. Therefore, when you command Alexa, for instance to wake up, your voice command is captured by the microphone which then relay it to servers, which processes the command and figure out what has been asked.
~ Thereafter, the servers issue appropriate instructions to Alexa on how it should respond to your command, in this instance, it turns on. This entire process lasts for only one second, and this attests to the efficiency of communication between Alexa and the cloud network of servers maintained by Amazon.
~ Alexa is central to the operations of the All New Echo Dot(2nd Generation)-Black. Alexa allows you to stream music from online music streaming platforms such as spotify, Pandora, and Amazon Prime Music; as well as stream podcasts from TuneIn and iHeartRadio. Moreover, Alexa can read news, set kitchen timers, set alarms, and even tell jokes. You can increase the functionality of Alexa by adding compatible third-party apps to its library. These third party apps are called skills, and not only increase the scope of app services, but they also make Alexa smarter.
