Answer:
Bluetooth is a wireless communication is typically limited to six feet distances
Explanation:
Bluetooth is one type of communication maximum it covers 10 meters to 30 meters. but it is one to one communication made for data transactions. After 25 meters of coverage on communication will be very slow on data transactions. But Bluetooth has also had a limitation.
IR. It is one of communication where infrared technology used. It is like face to face communication and speed of data transaction limited and it is also one to one communication made for data transactions. Communication paired and covered very little distances.
NFC it is chip-based and covers very little in fact just to device meet each and communication started. And very it caries very little data during the data transactions. it is also one to one communication made for data transactions
RFID is one of communication and it is powerful to cover more areas with multiple connections at the same time. It has a limitation in distance and it covers like a net with a specific distance
In the NumPy function, the data preparation technique that is used to help machine learning algorithms is called the reshape technique or function
For better understanding, let us explain what the reshape function means
- The numpy package helps to give the right tools for scientific and mathematical computations in python
. it includes functions that cam be used to perform common linear algebra operations, fast Fourier transforms, and statistics
The reshape function simply alter or change the row and column arrangement of data in numpy function and it is said to just give new shape to an array without the altering of its data.
from the above, we can therefore say that the answer In the NumPy function, the data preparation technique that is used to help machine learning algorithms is called the reshape technique or function is correct

Answer:
//""Print results to screen""
Explanation:
In c,c++,java,javascript // is used for the single line comment.
syntax:- // comment.
Whatever text that is followed after // is commented means this line will not get executed by the compiler.
Comments are used to explain the code to other person who is working on the code or trying to understand that code.
