HTTP and HTTPS protocols in Intro to Computing - Flowchart & Logic Diagram

Process Overview

HTTP and HTTPS are protocols that help your web browser and websites talk to each other. HTTP sends data openly, while HTTPS adds a lock to keep data safe.

This flowchart shows how a web browser requests a website using HTTP or HTTPS, highlighting the secure connection steps for HTTPS.

Step-by-Step Trace - 8 Steps

Step 1: User types a website URL in the browser

Step 2: Browser sends a request using HTTP or HTTPS

Step 3: Check if HTTPS is used

Step 4: If HTTPS, browser and server establish a secure connection using SSL/TLS

Step 5: Server sends encrypted data back to the browser

Step 6: Browser decrypts the data and displays the website

Step 7: If HTTP, server sends data openly without encryption

Step 8: Browser displays the website

This diagram shows how data moves between browser and server memory during HTTP and HTTPS communication, highlighting encryption and decryption steps.

Flowchart Quiz - 3 Questions

What does HTTPS add to the communication between browser and server?

A Encryption to protect data

B Faster loading speed

C More colorful websites

D No difference from HTTP

Key Result

HTTPS protects your data by encrypting it between your browser and the website, unlike HTTP which sends data openly.
