Hello Palak,
It's Indeed very nice to hear from you that you are interested in doing graduation in engineering after completion of your Diploma in civil branch in DTU. I am afraid your desired branch that is computer science is not available for students seeking lateral admission. I am attaching a link that will give you all the required information about lateral admissions in Delhi Technological University and its various courses that it offers and also about the entrance test that Diploma holders have to give.
