Explanation:
The wake-up receiver is an ultra-low power chip that continuously looks out for a specific radio signal, called a wake-up signature, that tells it when to wake up the main device
Answer:
The solution code is written in Python 3
- import random
- import string
-
- def simulate_several_key_strikes(l):
- char_set = string.ascii_lowercase
- return ''.join(random.choice(char_set) for i in range(l))
-
- print (simulate_several_key_strikes(10))
Explanation:
The program is aimed to generate random characters and the number of characters generated is dependent on user input. Hence, we will need to import the random module (Line 1). We also import string module so that we can make use of its associated method to generate English letters (Line 2)
Next, we create the function simulate_several_key_strikes that takes one single parameter, l, as input. Within the function body, we use ascii_lowercase method to generate the lowercase letter set and assign it to char_set variable (Line 5). We use random.choice method to randomly pick one of the letter in char_set and join it with an empty string (Line 6). Please note there is a for-loop that will repeatedly generate l-number of character and eventually return it as output.
We test the function by passing 10 as input parameter and we shall get a sample output as follows:

The only one that would make sense in for this is C
Answer- C
Answer:
A. Smart card
Explanation:
Smart cards contain a chip that can store a large amount of information as well as on a magnetic stripe for backward compatibility.
Smart card are cards made of plastic or metal material that has an embedded integrated chip that acts as a security token. Smart cards are the same size as a debit or credit card.
They connect to a reader either by a chip (microcontroller or an embedded memory chip) or through a short-range wireless connectivity standard such as radio-frequency identification or near-field communication.
It can be used to perform various functions though most commonly are used for credit cards and other payment cards.
