🌟 What is Quality of Service (QoS)? QoS refers to a network’s ability to provide predictable service quality — essential for real-time and critical applications (VoIP, video streaming, online gaming). It focuses on managing network resources to meet performance requirements. 📏 Key QoS Metrics Bandwidth – Data transfer capacity of the network. Delay (Latency) – Time for a packet to reach the destination. Jitter – Variation in delay; critical for media quality. Packet Loss – Percentage of packets that fail to reach destination. 🛠 Mechanisms to Ensure QoS Traffic Classification and Prioritization ...

📡 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. ...
