What is DC bin?
The first bin is the DC which is the sum/average of the samples in time domain. It’s zero if your signal is zero mean.
What is a bin in signal processing?
frequency bins are intervals between samples in frequency domain. For example, if your sample rate is 100 Hz and your FFT size is 100, then you have 100 points between [0 100) Hz. Each such small interval, say 0-1 Hz, is a frequency bin.

How is a frequency bin similar to a DFT?
Similar concepts can be found in probability bins. An FFT is a method of computing a DFT. And a DFT is a transform of a finite length vector which produces the same finite number of results. However the range of frequencies of a sinusoid that can be windowed to a finite length in order be fed to an FFT is infinite.
Are there frequency bins that cover the whole spectrum?
Classically, the frequency bins are even in size, non-overlapping, and cover the whole spectrum. On occasion, they can somehow overlap, be non-uniform, for instance when this term is used (rarely) for multirate filter banks.
Is there a single peak in a FFT bin?
Although one might expect a single peak, as one would obtain on the full continuous-time signal with a continuous Fourier transform, the peak is not precisely localized with an FFT, and leaks in the neighboring bins.
Which is the highest frequency in a frequency bin?
From that and knowledge of sampled audio, the highest frequency in the bins cannot be more than half the samplerate (in Hz). Also, according to this stack conversation, 0 is the lowest bin frequency (a.k.a. the DC component).
