A discrete cosine transform is a math process that can be used to make things like MP3s, and JPEGs smaller. It does this by breaking the sound or picture into different frequencies.
One way to calculate a discrete cosine transform is to use the Fourier transformation. "Discrete" means that it works on discrete-time signals (sampled data).
