When you play a move the computer considers numerous possible moves for it to play. After each one, there is a separate part of the program that has an "evaluation" capacity which assigns a number to each of the positions. It does this based on what the programmers have determined, including number of pieces, value of the pieces, the amount of space each side controls, etc. The computer then makes the move that it determines will result in the position with the highest evaluation, that is, it thinks it is best for itself. This is actually a simplification because computers will consider many moves, it will not only look at its next move and your next move after that, but then looks at its next move after that and then determines the evaluation.
