A transmission medium is the physical pathway that connects computers, devices, and people in a network, facilitating the transfer of data, signals, and information. It can be classified into guided media like cables and unguided media such as wireless signals, each with unique characteristics affecting bandwidth, latency, and noise levels.

Latency refers to the delay between a user's action and the corresponding response in a system, crucial in determining the perceived speed and efficiency of interactions. It is a critical factor in network performance, affecting everything from web browsing to real-time applications like gaming and video conferencing.

latency

Noise levels refer to the magnitude or intensity of sound in a given environment, typically measured in decibels (dB). Managing these levels is crucial for maintaining auditory health, concentration, and overall well-being, especially in urban and industrial settings.
