Communication --- Model 2: Shannon–Weaver’s Communication Model 📖 Explanation: Shannon–Weaver Model (1949) like a Professor Lecture 🔧 The Birth of a “Mathematical” Message Machine… In the late-1940s, at the buzzing research halls of Bell Telephone Laboratories, two brilliant minds—Claude Shannon, an engineer obsessed with binary signals, and Warren Weaver, a linguist-turned-scholar—sat staring at a tangle of wires and blinking lights. > Weaver: “Claude, telephones let people talk across continents, but lines crackle and words get distorted. How can we describe that, mathematically?” Shannon (tapping his slide rule): “Let’s imagine every conversation as a coded journey from one brain to another.” They grabbed a chalkboard and drew a straight path: Information Source → Transmitter → CHANNEL → Receiver → Destination (Noise sneaks in here!) 1. Information Source (Sender): The person who decides to speak. 2. Transmitter (Encoder): The telephone mouthpiece turns speech into electrical pulses. 3. CHANNEL: Copper wires carry the pulses across miles, but… 4. NOISE: Static, crackles, and line disturbances try to scramble the pulses. 5. Receiver (Decoder): The earpiece turns pulses back into sound. 6. Destination (Receiver): The listener’s ear—and mind—finally hears the message. That simple drawing became the Shannon–Weaver Model, nicknamed the “Mathematical Model of Communication.” It treated messages like data moving down a single-lane highway, where any pothole (noise) could flip a 0 into a 1, or twist “hello” into “yellow.” > Shannon: “If we measure and reduce noise, we boost accuracy.” Weaver: “And we can apply the same logic to human language, radio, TV—any system that sends symbols!” Their model revolutionized telecommunications and planted the seeds for information theory, digital coding, and even today’s Wi-Fi error-correction tricks. ✅ Exam-Fact Nuggets Creators: Claude E.
