___ 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.

Consider your program for the Spinning Out section. How might you adjust your code to stop your SDV after spiraling outward on a 5 x 5 grid? How about a 7 x 7 grid?
Answer:
To adjust the code for the Spinning Out section to stop the SDV after spiraling outward on a 5 x 5 grid, you could add a conditional statement that checks the current position of the SDV and stops the program if the position exceeds the limits of the grid.
For example, you could add the following code to the end of the main loop:
if (x > 5 || y > 5) {
break;
}
This will stop the program once the SDV has moved beyond the 5 x 5 grid.
To stop the program after spiraling outward on a 7 x 7 grid, you would simply need to update the conditional statement to check for a maximum position of 7 in both the x and y directions:
if (x > 7 || y > 7) {
