Inaiku cs classu👍 Web servers and browsers communicate using standardized three‑digit codes called HTTP status codes. When you navigate to a webpage, your browser sends a request to the server: if the server locates the resource, it replies with 200 OK; if it can’t find the page at all, it replies with 404 Not Found. In essence, a 404 error simply tells you that the server is running and understood your request, but the specific page you asked for is missing—either because it never existed, was moved without updating the link, or was deleted. These status codes are grouped by their first digit to indicate the general class of response: 1xx for informational messages, 2xx for successful requests, 3xx for redirections, 4xx for client‑side errors, and 5xx for server‑side failures. Within the 4xx range, codes become more specific—400 signals a bad request, 401 means unauthorized, 403 is forbidden, and 404 denotes “not found.” The choice of 404 is therefore not arbitrary but fits neatly into this logical scheme: any user request that can’t be fulfilled because the resource is missing falls under the 4xx client‑error umbrella, and “04” within that range was designated for “not found.” Over the years, a colorful myth has grown that “404” refers to a Room 404 at CERN—the birthplace of the World Wide Web—where missing‑page errors were supposedly handled. In reality, this story is just internet lore. Tim Berners‑Lee and his colleagues confirm there was no such error‑handling bunker; they simply chose 404 for clarity and consistency. Today, many sites embrace the frustration of a missing page by turning their 404 screens into playful graphics, mini‑games, or helpful search tools, reminding us that even in error, the web can surprise us with creativity. #404error #httpcode #tamil #simplywaste

HTTP vs HTTPS: The Real Reason 🔐 --- In interviews, we often say “HTTPS is secure, HTTP is not” — but the real reason is rarely explained properly. In HTTP, data travels as plain text, which means anyone in between (like attackers or intermediaries) can read or intercept the packets. In HTTPS, data is protected using TLS encryption. TLS encrypts the communication between the client and the server, so even if someone captures the packets, they can’t understand the data. This video explains: • Why HTTP is insecure • How plain-text data can be read in transit • How TLS encryption makes HTTPS secure If you’re a developer, student, or preparing for interviews, this is the explanation you should actually give. Save it. Share it. Understand it. 🔐🚀 --- #HTTPS #SystemDesign #DeveloperLife #TechExplained #CodingInterview

🌐 Cloud series - Day 41 What is HTTP & HTTPS? @mr_shiva_tech_talks Ever wondered what happens when you open a website? 🤔 🔹 HTTP (HyperText Transfer Protocol) It’s the basic protocol used to transfer data between your browser and server. 👉 Not secure ❌ – data is sent in plain text 🔹 HTTPS (HyperText Transfer Protocol Secure) A secure version of HTTP 🔐 👉 Uses encryption (SSL/TLS) to protect your data 👉 Keeps your passwords & personal info safe 💡 Simple Example: HTTP = Like sending a postcard (anyone can read it) HTTPS = Like sending a sealed envelope (secure & private) 🚀 Always look for HTTPS before entering sensitive info online! #fypppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppp #tech #viral #python #cloudcomputing

Http Status Codes explicados de forma SENCILLA Parte 2🤩 ¿Qué son los status code? Son respuestas que devuelve un servidor cuando vos hacés una petición (por ejemplo, entrar a una página web). Sirven para indicar si la solicitud se pudo cumplir bien, si hubo algún error o si hace falta que el cliente (tu navegador, una app, etc.) haga algo más. 👉 Se dividen en grupos, según el número con el que empiezan (100, 200, 300, 400 y 500) y cada uno tiene su propio significado. Y vos... ¿Habías trabajado con Status Codes? #tech #python #programmer #webdev #coding #microsoft #http

Everyone says — “HTTPS is secure.” But as developers, that doesn’t tell us anything. So here’s the real explanation — from a software engineering + networking + backend systems POV 👇 What they actually are 🔹 HTTP — HyperText Transfer Protocol Application-layer protocol that defines how clients & servers exchange data — methods (GET/POST), headers, status codes, caching, cookies, payloads etc. It only handles communication semantics, not protection. 🔹 HTTPS — HTTP over TLS (Transport Layer Security) Same HTTP protocol — but wrapped inside a cryptographic TLS tunnel. Nothing changes in routes, APIs, JSON payloads or application logic… only the transport layer gains encryption, integrity & identity verification. 🧩 The real technical differences 1️⃣ Encryption (Prevents traffic sniffing) TLS handshake negotiates symmetric keys → packets become unreadable on Wi-Fi networks, proxies, corporate firewalls, ISP monitoring. 2️⃣ Integrity (Prevents packet tampering) MAC / AEAD ensures if data is modified → connection breaks. Plain HTTP cannot detect injections or alterations. 3️⃣ Server Identity & Trust Chain Certificates validate domain → protects against MITM, rogue DNS, hotspot proxies. HTTP has no concept of authenticity. 4️⃣ Cookie & Auth Token Safety HTTPS allows Secure, HttpOnly, SameSite attributes → reduces session hijacking & credential leakage. 5️⃣ Performance & Protocol Upgrades Modern web performance requires HTTPS: HTTP/2 multiplexing HTTP/3 / QUIC Service Workers / PWAs Brotli compression In real networks → HTTPS is often faster than HTTP. 6️⃣ Platform & Browser Policies On HTTP, many APIs are blocked (Geo, Clipboard, Camera, PWA install). Forms marked Not Secure. SEO rankings drop. 7️⃣ Ports & Transport HTTP → 80 HTTPS → 443 Protocol semantics remain the same — transport layer changes. 🟡 Developer takeaway HTTP = application protocol HTTPS = HTTP + TLS (encryption + integrity + identity) The core difference isn’t “secure vs insecure” — it’s: ✔ Can traffic be read? ✔ Can it be modified? ✔ Can the server be impersonated? ✔ Can modern web & network features run? #HTTPvsHTTPS #WebDevelopment #backend #softwareengineering #womenintech System design
