What protocol is commonly used for secure web browsing?

• A. FTP (File Transfer Protocol)
• B. HTTP (Hypertext Transfer Protocol)
• C. SMTP (Simple Mail Transfer Protocol)
• D. HTTPS (Hypertext Transfer Protocol Secure)

Answer: (D)

The protocol commonly used for secure web browsing is HTTPS, which stands for Hypertext Transfer Protocol Secure. This protocol is an extension of HTTP and is designed to provide a secure communication channel over a computer network. HTTPS utilizes encryption protocols, such as SSL (Secure Sockets Layer) or TLS (Transport Layer Security), to create a secure connection between the web server and the client’s browser. This encryption helps to protect sensitive information, such as login credentials, credit card data, and personal details, from being intercepted by third parties during transmission. When a user visits a website using HTTPS, they can be assured that their data is encrypted and secure, which is particularly important for sites that handle sensitive operations, such as online banking or e-commerce. Consequently, web browsers indicate this secure connection by displaying a padlock symbol in the address bar, providing users with confidence that their communication with the website is protected. In contrast, protocols like FTP, HTTP, and SMTP do not provide this level of security. FTP is used mainly for transferring files between devices but does not encrypt data. HTTP, while widely used for web browsing, transmits data in plaintext, leaving it vulnerable to interception. SMTP is primarily used for sending emails and does not cater to secure web browsing needs
