What is noisy and noiseless channel?

The exploration of protocols is split into those that can be applied for noiseless(error-free) channels and those that can be used for noisy(error-causing) channels. The first category of protocols cannot be used in actual life, but they serve as a basis for protocols for noise channels.

What is noisy channel?

The noisy channel model is a framework used in spell checkers, question answering, speech recognition, and machine translation. In this model, the goal is to find the intended word given a word where the letters have been scrambled in some manner.

What are noisy channels in data communication?

Noisy Channel: Noisy Channel means that there will be lot of disturbance in the path when data is carried forward from sender to receiver.

What are the protocols used in noisy and noiseless channel?

The simplest protocol is a data link layer protocol used for noiseless channels. It is also known as the Elementary Data Link Protocol. As the simplest protocol is used in noiseless channels, it has no error control and no flow control.
