4/ DNS = The Translator ๐Ÿ”„.DNS converts the human-readable domain into its machine-readable IP. โšก To save time, ISPs cache the results so you donโ€™t wait every time. #DNS #CloudComputing.

2/ Registrars & ICANN ๐Ÿข.Domains are sold by registrars (like Google Domains). But the whole system is regulated by ICANN, the global internet authority. ๐ŸŒ. #Internet #Domains.

AI isnโ€™t about math only. Itโ€™s about storytelling. Can your ML model explain WHY it made a decision?.Explainability > Accuracy. Python has SHAP and LIME just for this. Future belongs to interpretable AI. #XAI #Python #MachineLearning.

Learning Python for AI? Donโ€™t just copy tutorials. ๐Ÿ‘‰ Pick a dataset (Kaggle, UCI, your own life logs). ๐Ÿ‘‰ Try building a mini-model. ๐Ÿ‘‰ Fail. Debug. Learn. Thatโ€™s where real ML skills are born. #Python #MachineLearning #AI.

โœ… Key takeaway:.Next time you stream a video or open a website, remember that UDP & DNS are silently working behind the scenes. #Day6 #Networking #ComputerScience #LearnInPublic.

3/ How it works. You type a domain name. DNS + ISP + ICANN work together to find the right IP. Browser connects you to the server instantly. All thanks to a decentralized system that keeps the web human-friendly ๐ŸŒ.

2/ DNS (Domain Name System).Think of DNS as the internetโ€™s phonebook ๐Ÿ“–. It maps:.๐Ÿ‘‰ โ†’ 152.158.1.39XX.(Names โ†’ Numbers). Without it, weโ€™d be memorizing IP addresses instead of names ๐Ÿ˜….

1/ UDP (User Datagram Protocol). No need for connection setup ๐Ÿš€. Some packets may arrive late or never, but speed > reliability. Used in live streaming, video calls, and online games ๐ŸŽฎ. Also powers DNS queries.
