The correct answer is HTTPS. HTTPS (Hypertext Transfer Protocol Secure) is the protocol used for secure communication over a computer network, particularly on the internet.
– HTTPS is the secure version of HTTP, where ‘S’ stands for Secure.
– It uses SSL/TLS (Secure Sockets Layer/Transport Layer Security) encryption to secure the connection between a user’s browser and a server. This ensures that data transmitted is protected from eavesdropping and tampering.
– HTTP (Hypertext Transfer Protocol) is the standard protocol for transmitting web pages but does not provide encryption, making it insecure for sensitive data like passwords or credit card information.
– FTP (File Transfer Protocol) is used for transferring files between computers. While secure versions exist (like SFTP or FTPS), the standard FTP is not secure.
– DHCP (Dynamic Host Configuration Protocol) is a network management protocol used for dynamically assigning IP addresses and other network configuration parameters to devices on a network. It is not a communication protocol for data transfer in the same sense as HTTP or HTTPS.
