Putting all government forms on the city web site is the least activity likely to be effective in the purpose of reducing digital divide.
Holding basic computer classes at the community centers will very much help to reduce the digital divide.
Providing free wireless internet connections at locations in low-income neighborhood will also reduce the gap of digital divide
Requiring that every city school has computers that meet a minimum hardware and software will made computing resources available to users thereby reducing digital divide.
Answer:
Neural Networks
Explanation:
Neural networks are networks that mimic the behaviour of the human brain in which they tend to perform a task without been programmed with the task rule, although the neural network are artificial in nature and they often recognize patterns.
Neutral network have cell that enable them to carry out task together in order to produce a desired result and the cell can only solve a little part of tasks.
Technician A is correct.
Electrochemical batteries can be classified into two main categories; Primary Cells and Secondary Cells.
A primary battery or cell cannot easily be recharged after use and is usually recommended to be discarded following discharge. Most primary cells are termed dry due to their capability of utilizing electrolytes contained within absorbent material.
A secondary cell, on the other hand, can be recharged electrically to their original pre-discharge condition.
Answer:
See explaination for the code
Explanation:
def wordsOfFrequency(words, freq):
d = {}
res = []
for i in range(len(words)):
if(words[i].lower() in d):
d[words[i].lower()] = d[words[i].lower()] + 1
else:
d[words[i].lower()] = 1
for word in words:
if d[word.lower()]==freq:
res.append(word)
return res
Note:
First a dictionary is created to keep the count of the lowercase form of each word.
Then, using another for loop, each word count is matched with the freq, if it matches, the word is appended to the result list res.
Finally the res list is appended.
