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

A palindrome is a string that reads the same from left to right and from right to left. Design an algorithm to find the minimum
stepladder [879]

Answer:

Explanation:

The following code is written in Python. It is a recursive function that tests the first and last character of the word and keeps checking to see if each change would create the palindrome. Finally, printing out the minimum number needed to create the palindrome.

import sys

def numOfSwitches(word, start, end):

   if (start > end):

       return sys.maxsize

   if (start == end):

       return 0

   if (start == end - 1):

       if (word[start] == word[end]):

           return 0

       else:

           return 1

   if (word[start] == word[end]):

       return numOfSwitches(word, start + 1, end - 1)

   else:

       return (min(numOfSwitches(word, start, end - 1),

                   numOfSwitches(word, start + 1, end)) + 1)

word = input("Enter a Word: ")

start = 0

end = len(word)-1

print("Number of switches required for palindrome: " + str(numOfSwitches(word, start, end)))

Nataly [62]

Answer:

The Hobbit’s main theme is Bilbo’s development into a hero, which more broadly represents the development of a common person into a hero.

When Gandalf talks him into embarking on the quest with Thorin’s dwarves, Bilbo becomes so frightened that he faints. But as the novel progresses, Bilbo prevails in the face of danger and adversity, justifying Gandalf’s early claim that there is more to the little hobbit than meets the eye.??????
