How is data rate related to frequency?

The relationship of speed to frequency is a bit complex, but in simple terms, higher frequencies are needed to carry more bits of data. Each data bit is encoded on a carrier frequency, and the amount of data that can be transmitted per second depends on the signal encoding scheme of the active equipment.

Is data rate the same as frequency?

The data rate is determined by how quickly you switch between "on" and "off". Frequency is irrelevant; the carrier wave is always at the same, unchanging frequency. [Note: you're not necessarily restricted to two amplitudes.

Does higher frequency mean higher data rate?

Higher frequencies allow larger bandwidth and more data to travel through a channel, if the architecture of the channel is such that the data is not garbled by interference.

How is bit rate related to frequency?

If one cycle of signal carries 1 bit of information, then the frequency of the system (in hertz) equals its speed (in bits per second). However, there is no reason why a single cycle cannot carry more than 1 bit of information. Therefore, increasing the speed of a system without changing its frequency is possible.
