What does it mean to window a signal?

The process of windowing a signal involves multiplying the time record by a smoothing window of finite length whose amplitude varies smoothly and gradually towards zero at the edges. The length, or time interval, of a smoothing window is defined in terms of number of samples.

Why do we use windowing in DSP?

Basically, window functions are used to limit a signal in Time (to make it shorter), or to improve artifacts of the Fourier transform.
