TCP vs UDP: Which one to use? Learn the differences and use cases in this video.

Love the package delivery analogy for explaining UDP and TCP! However, I think the UDP guy's actions could better illustrate the connectionless nature of UDP. Instead of kicking the package, why not have him simply throw it from a distance without waiting for confirmation? This would show how UDP prioritizes speed over reliability.

The TCP/IP model powers the internet — and every developer should know it. This video makes the layers and protocols crystal clear, even if you’re just starting out.

TCP/IP goal (1970s): “Any host can talk to any host.” Blockwidth goal (2020s): “Any intent-carrying signal can arrive predictably enough to keep independent machines in better sync and coordination.”

🚀 TCP vs. UDP: The Handshake That Makes All the Difference 🤝 When devices communicate over the internet, they rely on two key transport protocols: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). While both get your data from point A to point B, they do it in very different ways—with trade-offs that matter depending on the use case. Here’s a quick breakdown to help you understand when to use which:

TCP & IP --> TCP = Transmission Control Protocol --> IP = Internet Protocol. " IP: Like your house address (tells where data should go " " TCP: Like a delivery system ( makes sure the parcel/data reaches safely, in order, without loss ".

New blog post: Ethernet Frames: The Unsung Heroes of Your Network Without them, your data’s just chaos in the void. With them, we get order, VLANs, and fewer broadcast meltdowns. A quick guide to Layer 2 for anyone brushing up on CCNA or just curious how networks actually keep it together.

Are you battling protocol compatibility on the plant floor? This video provides some practical solutions to consider in the age of TCP/IP.

Day 28️⃣ | GATE 2026 CSE Preparation 📚 Topic of the Day: Computer Networks – OSI & TCP/IP Models 🔑 Key Points: OSI Model: 7 Layers (Physical → Application) TCP/IP Model: 4 Layers (Link, Internet, Transport, Application) Functions of each layer (Encapsulation, Addressing, Error Control, Routing) Protocol examples: HTTP, FTP, SMTP, IP, TCP, UDP, Ethernet ⚡ Tip: Always compare OSI vs TCP/IP – GATE often asks differences & mapping between them. #GATE2026 #CSE #ComputerNetworks #OSIMode #TCPIP #GatePreparation #Day28

Every new TCP connection = 3-way handshake overhead. Keep-Alive keeps the connection open, skipping the repeated setup → faster requests, lower latency. 🚀"
