When handling a connection timeout exception in Android, the first step is to ensure that the app has the necessary permissions declared before attempting any network operations. Then, utilize the HttpURLConnection class to connect to the URL and set the timeout values. If the connection times out, catch the IOException and handle it gracefully. Depending on the response needed, the app can either prompt the user to retry the connection or display an error message. Finally, use the disconnect() method to close the connection to avoid memory leaks.

1. Earn a degree in cyber security: A bachelor’s degree in cyber security, computer science, information technology or a related field is the first step to become a cyber security specialist.

Encryption is the process of encoding a message or information in such a way that only authorized parties can access it. This is done with the use of algorithms and keys. Hashing, on the other hand, is a one–way form of cryptography where a given input is converted into a unique output, known as a hash, using an algorithm. Hashing cannot be reversed, so it cannot be used to retrieve the original input. It is mainly used to verify the integrity of data.
