Answer:

A. Switches identify the intended destination of the data that they receive. And C. Switches are capable of sending and receiving data at the same time

Explanation:

Switches can be used as inputs (Analog), or outputs (digital). These inputs and outputs are signals that the switches send or receive- Or at least as push button switches... But the same applies to network switches.

Hope this helps! Have a great day!

Alex writes down a string with four digits. (Since this is a string, not a number, it can start with a $0.$ For example, Alex co
Artist 52 [7]

Answer: The answers to all parts of this question are based on "automatic string". The condition is also provided which states that the string the machine outputs is the same string (4-digit string) which is fed to the machine as input.

Explanation: (a) The string will not remain automatic string if it contains a digit greater or equal to $5$. As we know that machine should print the same string which is fed into it. In this case the machine will insert a 0 in place of $5$. So the number is inserting a 0 when it is output by the counting machine. For example if we input $2152$ machine will print "$0120$" which shows that the digits are not the same as fed to the machine. If we take string $0702,$ which is given in the question, we see that machine prints out "$2010$" which means that number is inserting a 0 so automatic string cannot contain a digit greater than $5$

(b) The same answer as given in (a). For example the if we write $4220$ machine prints out "$1020$".  So the automatic string cannot contain $4.$

(c) This is a bit tricky as machine count the digit $3$. Lets take an example string $3303$. the machine prints out "$1003$". It counts three BUT its not an automatic string because the string printed out is different from the string that was fed to the machine. So automatic string cannot contain $3.$

(d) Now we know that an automatic string cannot contain digits 3,4,5 and above. So it can contain digits 0,1 and 2 with 0 at the end as the automatic string cannot contain digit 3 or above.Lets take a few examples of strings with combinations of 0,1 and 2 to check if they are automatic strings.

  • $1220$ the machine prints $1120$ which is not the same as fed into machine so its not an automatic string.
  • $2020$ the machine prints out "$2020$". Its 2 times "$0$", 0 times "$1$",2 times "$2$" and 0 times "$3$" which is the same as fed to machine so $2020$ is an automatic string.
  • $1210$  is an automatic string as the machine prints out "$1210$" which is the same string fed to machine.

Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integer
dalvyx [7]

Answer:

The program is as follows:

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

   for i in user_values:

       if i <= upper_threshold:

           print(i,end=" ")

           

def get_user_values():

   user_values = []

   n = int(input())

   for i in range(n):

       num = int(input())

       user_values.append(num)

   

   upper_threshold = int(input())

   output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold)

get_user_values()

Explanation:

This defines the output_ints_less_than_or_equal_to_threshold method

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

This iterates through user_values

   for i in user_values:

For every item in user_values

       if i <= upper_threshold:

This prints all items less than or equal to the upper threshold

           print(i,end=" ")

           

This defines get_user_values method

def get_user_values():

This creates an empty list

   user_values = []

This gets the number of inputs

   n = int(input())

This iterates through n

   for i in range(n):

This gets input for every item of the list

       num = int(input())

This appends the input to the list

       user_values.append(num)

This gets input for upper threshold    

   upper_threshold = int(input())

This calls output_ints_less_than_or_equal_to_threshold method

   output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold)

The main begins here; This calls get_user_values method

get_user_values()
