🔎 DNS – The Domain Name System 📜. This system translates domain names (like google.com) to the machine-readable IP addresses 🆔 needed for locating and routing traffic on the internet.

🌐 HTTP – The Hypertext Transfer Protocol. This application layer protocol defines how web clients 💻 and servers 🖥️ communicate. HTTP establishes connections, specifies request methods (GET, POST) 👾 and response codes (404, 500)❗️, and formats & transports web pages, assets, APIs etc.

🔒 HTTPS – HTTP Secure 🔒. It’s the same as HTTP but with added encryption 🔏 of communication and authentication 👤 of servers through SSL/TLS certificates 🪪. This provides security and data privacy.

✉️ SMTP – Simple Mail Transfer Protocol. The standard protocol for email 📧 transmission between servers over the internet. SMTP handles formatting, transmission, routing, and delivery of email.

🗂️ FTP – File Transfer Protocol. Allows transferring files (uploading & downloading) between hosts over TCP networks. Widely used for exchanging files between client 💻 and server 🖥️ programs.

⚡️ UDP – User Datagram Protocol. A lightweight transport layer protocol used for time-sensitive transmissions like video streaming 📺, online gaming 🎮, and voice chats 💬.
