Examples of Input and Output in Web Basics Algorithms

📚 Quick Study Guide

• 🖥️ Input: Data provided to a web application or algorithm. This can come from various sources like user forms, databases, or APIs.
• 📤 Output: The result produced by a web application or algorithm after processing the input. This is typically displayed to the user or used for further processing.
• ⌨️ User Input: Data entered by a user through forms, buttons, or other interactive elements.
• 💾 Database Input/Output: Reading data from a database (input) and writing data to a database (output).
• 🌐 API Input/Output: Sending requests to an API (input) and receiving responses (output).
• 🧮 Algorithm: A set of steps that processes input data to produce a specific output.
