Explain what the TLS protocol is and what it is used for on the internet.

TLS (Transport Layer Security) is a cryptographic protocol that provides a secure connection between a client and a server on the internet. It is used to protect data from interception and tampering, ensuring confidentiality, integrity, and authentication.

An example of TLS usage is HTTPS, where a browser establishes a secure connection with a website, encrypting the transmitted data so that no third party can read or modify it.
