a) A protocol for encrypting data transmitted over the internet
b) A method for assigning IP addresses
c) A tool for compressing network traffic
d) A network routing device
Answer:
a) A protocol for encrypting data transmitted over the internet
Explanation:
SSL (Secure Sockets Layer) is a cryptographic protocol that provides encryption and authentication for data transmitted over the internet. It is commonly used to secure web traffic, ensuring that sensitive information, such as passwords and credit card details, is protected from interception.
SSL creates a secure, encrypted link between a user’s browser and a web server, preventing third parties from accessing or altering the data being transmitted. Websites that use SSL are identified by the “https” prefix and a padlock symbol in the browser’s address bar.
SSL is essential for protecting the privacy and security of online communications, particularly when transmitting sensitive information over the internet.
