26. Summary And Conclusions The modules drivers utilize all the modules potential, and yet are very simple to understand and use. The modules can work simultaneously without interruptions, and support both Hebrew and English. The modules drivers utilize all the modules potential, and yet are very simple to understand and use. The modules can work simultaneously without interruptions, and support both Hebrew and English. When designing an application for the device, a deep thought should be directed to how to implement the application with a constant space complexity, in the expense of time complexity.
