Question 38

What is a protocol?

Answer 38

A protocol is a set of rules that computers follow to communicate with each other. These rules tell computers how to send, receive, and understand messages correctly. It’s similar to how people need to speak the same language and take turns when texting—protocols make sure computers stay in sync and avoid confusion. Examples include: • HTTP – used for loading websites • Wi-Fi protocols – for connecting wirelessly • Bluetooth – for short-range device communication Without protocols, computers wouldn’t know how to share information or work together.

Question 39

Answer 39

1. How to start and end communication (e.g., handshakes, connection setup) 2. How data is formatted (e.g., headers, message structure) 3. How data is sent (e.g., in chunks, with timing or order) 4. How to handle errors (e.g., retries, checksums) 5. How to confirm receipt (e.g., acknowledgments or status codes) 6. Who speaks when (e.g., turn-taking or flow control) These rules ensure reliable, clear, and coordinated communication between devices.

Answer 42

We use programming languages to give computers clear, step-by-step instructions they can follow. Each language has its own syntax (rules for writing code), just like grammar in English or Spanish. When you write a program, you’re basically creating a recipe the computer will follow to complete a task—like doing math, displaying a website, or playing a video. In short, programming languages are tools we use to create software and control what computers do.
