Design and Implementation of Online Examination System for Information Technology Fundamental
Abstract: This paper designs a B / S model based on the information technology based online examination system, the use of WAMP framework, static web pages using HTML5 standard, supplemented by JavaScript script programming. The system mainly includes the function modules such as user management, examination arrangement, examination arrangement, supervision and examination arrangement, test paper generation, examination examination, student online examination and so on. It can realize the test paper according to the knowledge and difficulty, the examination batch, the examination room student, Flexible arrangements, the use of JavaScript script to control the test interface to achieve anti-cheating effect, set the test 15 minutes before the buffer time to prevent the test server paralysis, student answers using random number algorithm to upload time to avoid server crashes. The main functions of the online examination system have been achieved, can be used as a teaching case to promote.
