The former occupying a great deal of memory is prone to be affected while the latter is very expensive. Our system is established on pure hardware,and is formed by adding relative controlling devices into the present teaching net. Its function includes rehearsal, practice, question and solution. This system occupies no memory,and is convenient to operate, and is stable in performance and costs little.
