Answer:
C. Z-wave
Explanation:
The Z wave is a wireless communications protocol used primarily for automation. The Z- wave operates using a mesh network and then uses low energy radio waves to communicate from appliance to appliance.
The Z wave operates on a lower frequency than most other popular RF devices, thus making interference nonexistent.
The range of the Z-wave is 100m. Hence, it can give a perfect coverage from the base station to the company.
<em>Option A is wrong</em> . This is because the Zigbee is insecure and has a low coverage range (10m-20m). This means that there are possibilities of interference and also improper coverage beyond 50 m.
<em>Option B is wrong.</em> This is because Bluetooth devices are insecure, can loose connections under certain conditions. They have a range of 10m which is a lot lower than 50m benchmark.
<em>Option D is wrong</em>. NFC stands for Near Field Communication. This means its range is practically about 4cm and it cannot be used for long ranges as the company intends.
Answer:
# The below code is in python programming language.
if(numberOfSides==4): #check the value number of slide is equal to 4 or not.
isQuadrilateral=True # assignment statement for if condition
else:
isQuadrilateral=False # assignment statement for else condition
Explanation:
The above code is in python language in which--
- The first lines are the "if" condition which checks the value of "numberofslides" variable.
- The second lines assign true in "isQuadrilateral" variable if "if" condition is true.
- The third line is for "else" statement that executes when the "if" condition is false.
- The fourth line is for "else" statement which assigns the value false to the numberofslides variables.
Information is very important because it helps us as a society make decisions. Decisions are impossible without information, and we are constantly seeking information in everything we do. Information is important in decreasing our sense of doubt and uncertainty as well.
