Much like multiplexing combines multiple signals into one in a digital system, the human brain receives input from the five senses—sight, hearing, taste, smell, and touch—and integrates them seamlessly into a unified perception of the world. Each sense delivers its own stream of sensory data, akin to the multiplexed channels of information in a digital system.

For example, when we experience a sunset, our eyes detect the colors and shapes of the sky, while our ears might pick up the sound of birds chirping or waves crashing. Additionally, we might feel the warmth of the sun on our skin, smell the scent of flowers nearby, and perhaps even taste the saltiness of the air. All these sensory inputs are processed concurrently by the brain, similar to how multiplexing handles multiple signals simultaneously. →
