What does SSL stand for and what is its purpose?

The term SSL stands for Secure Sockets Layer, and its primary purpose is to encrypt data transmitted over the internet between a web server and a client, such as a web browser. This encryption ensures that any information exchanged, such as personal data, credit card details, and login credentials, remains secure and cannot be easily intercepted by malicious actors.

By establishing an encrypted connection, SSL helps maintain the confidentiality and integrity of the data being transmitted, thereby fostering trust between users and websites. This technology is essential in creating a secure browsing environment, making it a core component of online security practices. The widespread use of SSL has evolved into the more modern version known as TLS (Transport Layer Security), but the foundational purpose remains the same: to protect data in transit.

The other options refer to terms or purposes that do not accurately describe SSL or oversimplify its primary function. For example, while email encryption is important, SSL specifically focuses on web communication. Similarly, creating virtual private networks and improving file sharing relates to different aspects of network security and data transmission.
