Channel capacity

Channel capacity refers to the maximum rate at which information can be transmitted over a communication channel without errors, given the level of noise and other factors affecting the connection. Think of it as the bandwidth limit: it determines how much data can flow through the channel efficiently. Higher capacity means more information can be sent in less time. It is a fundamental concept in communications engineering because it defines the ultimate limit of data transmission quality, ensuring that systems are designed to operate as close to this maximum as possible while maintaining accuracy.
