Communication Channels and Performance Metrics
📡 What Are Communication Channels? A communication channel is the medium used to transmit data between devices. It can be physical (wired) or wireless (radio, microwave, optical). 🧩 Types of Channels Wired: Coaxial, Twisted Pair, Optical Fiber Wireless: Radio Waves, Infrared, Microwave, Satellite Duplex Modes: Simplex: One-way (TV) Half-duplex: Alternating (walkie-talkie) Full-duplex: Simultaneous (phone) 🧪 Key Performance Metrics Bandwidth – Max data rate (bps) the channel can handle. Latency – Time for data to reach destination. Throughput – Actual rate achieved. Jitter – Variability in latency. Error Rate – Ratio of corrupted bits. SNR (Signal-to-Noise Ratio) – Quality of transmission. 🧠 Deep Insight Every communication channel is a conversation between chaos and clarity — a struggle to preserve signal in a sea of noise. Performance metrics quantify how faithfully and swiftly meaning travels through this medium. ...
