Determinate errors
have a definite direction and magnitude and have an assignable cause (their cause can be determined). Determinate error is also called systematic error. Determinate error can (theoretically) be eliminated.
Indeterminate errors
arise from uncertainties in a measurement. Indeterminate error is also called random error, or noise. Indeterminate error can be minimized but cannot be eliminated.
