Online Virtual lab is a web based application which will provide a simulation to the e-learning students to enhance their degree of excellence in distance learning education and to improve their practical skills related to science and technology fields. This web application will give an online laboratory environment, where an e-Learner performs practical work. This solution overcomes the problems faced in rural areas due to insufficient time and practical instruments/apparatus used in science laboratories. It is also beneficial for enhancing the students research oriented studies. By using this application lab experiments can be taught more efficiently and less expensively. The virtual labs can be made available to students with no access to physical labs or where equipment is not available. ELearning students can access these online experiments at home, anytime and anywhere. The application should have graphical user interface which have apparatus and practical instruments objects. The interface should provide selection of computer science practical courses such as programming course, digital logic design, and software engineering etc and under this select the introduction, experiment lists of selected topics, procedure of performing experiments, tutorials, reference materials etc

Based on the above scenario you are required to identify

students

Functional requirements:

simulate the manual laboratory experiment in the system and provide an artificial simulated online computer laboratory where experiments will be virtually carried out.All the laboratory apparatus will be made avalaible by the online virtual lab software .

Non Functional requirements

Highly available :Anytime experiments can be carried out

Highly portable: System which houses the virtual labs software can be carried out anywhere and experiment can be simulated

Highly efficient:less cost and more time saved in setting up and working manual apparatus.even speed is faster

relaible and safer
