Answer:

C. NFC

Explanation:

NFC stands for Near Field Communication. NFC is been embedded in recent mobile device (ranging from phone to tablet) to ease payment. NFC is a short-range high frequency wireless communication technology that enables the exchange of data between devices over about a 10 cm distance.

From the option, Bluetooth look like a probable answer but when they are both compared; we realized that NFC has a shorter set-up time over bluetooth and is therefore faster than bluetooth.

MakcuM [25]

Answer:

import os

import nltk

import zipfile

from nltk. corpus import gutenberg

from nltk. text import Text

def findWordFreq(text, word):

   textfreq = nltk. FreqDist(text)

   wordfreq = nltk.FreqDist(word)

   maxfreq = max(textfreq)

   return wordfreq, maxfreq

if -_name__ == '__main__':

   text = input()

   word = input()

   if not os.path.exists(os.getcwd() + "/nltk_data"):

       with zipfile.ZipFile("nltk_data.zip", 'r') as zip_ref:

           zip_ref.extractall(os.getcwd())

   os.environ['NLTK_DATA'] = os.getcwd() + "/nltk_data"

   text = Text(gutenberg.words (text))

   word_freq, max_freq = findWordFreq(text, word)

   print(word_freq)

   print(max_freq)

Explanation:

The natural language package in python is used to get and analyse word from voice input. The python code above get words from a zipfile extract, and the 'findWordFreq' function gets the word count and the maximum number of alphabet used in the word distribution.
