Answer:
True
Explanation:
Solution
ZigBee uses unlicensed frequency bands but operate at slower speed or data rates.
ZigBee: This communication is particular designed for control and sensor networks on IEEE 802.15.4 requirement for wireless personal area networks (WPANs), and it is a outcome from Zigbee alliance.
This communication level defines physical and (MAC) which is refereed to as the Media Access Control layers to manage many devices at low-data rates.

Hope this helps!! :)
Answer:
In serial communication transfers one bit of data at a time, while parallel communication transfers many bits of data at the same time. Serial communication transmits the data bits sequentially, while parallel communication transmits data bits simultaneously, allowing greater amounts of data to be transferred.
-Serial communication is the one used to communicate the Arduino with the Computer through the USB cable.
-An example of a parallel port is the printer port. The Parallel Port was only created and used in the printers interface and the computers.
Explanation:
In <em>serial communication</em>, each bit is sent by its own clock flank where conditions are defined after each byte, if it is synchronous or asynchronous. In <em>parallel communication</em> there is only one single clock flank where the information is sent where it is an advantage to use it where there are several input or output data.
I hope it's help you.
