___ requires a password when connecting to your router and makes your wireless transmissions unreadable by hackers
Wi-Fi encryption (such as WPA2 or WPA3) requires a password when connecting to your router and makes your wireless transmissions unreadable by hackers. Wi-Fi encryption is a method of securing wireless communications by encoding the data being transmitted over the airwaves.
This encoding makes it difficult for anyone who intercepts the data to read or understand it. The two most common forms of Wi-Fi encryption are WPA2 (Wi-Fi Protected Access 2) and WPA3. WPA2 uses a process called Temporal Key Integrity Protocol (TKIP) to encrypt the data. TKIP generates a unique encryption key for each packet of data that is sent, making it difficult for hackers to crack the encryption.
WPA3 is the latest version of Wi-Fi encryption. It is more secure than WPA2, and it uses a process called Simultaneous Authentication of Equals (SAE) to encrypt the data.

my_var = int(input("Enter a new value for my_var: "))
print("Inside the subroutine, my_var has a value of: ", my_var)
my_var = 0

my_subroutine(my_var)
print("Outside the subroutine, my_var has a value of: ", my_var)
What is the python program about?This program defines a subroutine called "my_subroutine" that takes one parameter called "my_var". The main program sets the initial value of "my_var" to 0 and then prints its value.
It then calls the "my_subroutine" and passes the current value of "my_var" to it as an argument. Inside the subroutine, the value of "my_var" is changed by prompting the user to enter a new value.
The new value is then printed along with a message indicating that it is inside the subroutine. After the subroutine is called, the main program prints the value of "my_var" again, along with a message indicating that it is outside the subroutine.
