    Question

    In the context of web development, which of the following best describes the primary difference between HTTP and HTTPS?

    A HTTPS uses port 443 while HTTP uses port 80 Correct Answer Incorrect Answer
    B HTTPS is faster than HTTP Correct Answer Incorrect Answer
    C HTTP supports stateful connections while HTTPS does not Correct Answer Incorrect Answer
    D HTTPS uses JSON for data transmission while HTTP uses XML Correct Answer Incorrect Answer
    E HTTPS requires an additional DNS server Correct Answer Incorrect Answer

    Solution

    The primary difference between HTTP and HTTPS is that HTTPS uses port 443, which is associated with SSL/TLS encryption, while HTTP uses port 80, which transmits data in plaintext. HTTPS (HyperText Transfer Protocol Secure) provides a secure connection by encrypting the data transmitted between the client and server using SSL/TLS protocols. This encryption ensures confidentiality, data integrity, and authentication, making it more secure than HTTP. Why Other Options are Incorrect: B) HTTPS is faster than HTTP: This is incorrect; HTTPS is generally slower than HTTP due to the encryption overhead, although the performance difference is minimal. C) HTTP supports stateful connections while HTTPS does not: Both HTTP and HTTPS can support stateless communication, not stateful. D) HTTPS uses JSON for data transmission while HTTP uses XML: Both protocols can transmit any data format (JSON, XML, HTML, etc.). E) HTTPS requires an additional DNS server: HTTPS does not require an additional DNS server; it uses SSL/TLS certificates to establish secure connections.
