Imaginary numbers: Imaginary numbers are multiples of i (the square root of -1). They have no real part but contribute to complex numbers when combined with real numbers.

Real numbers: Real numbers include all rational and irrational numbers. They do not have any imaginary components.

Complex plane: Also known as Argand plane or Gauss plane, it is a two-dimensional graph where complex numbers are represented by points, with the real part on the x-axis and the imaginary part on the y-axis.
