Hi dear,

Hope you are doing well!

Now let's go through your question.

Yes, you can pursue CSE after diploma in computer science and on your diploma basis you will be given a option if lateral entry where you can directly get admitted to second year of your engineering course.

The eligibility criteria varies from college to college.

After that you can also go for higher studies and can take admission in Post-graduate courses in engineering after completion of Graduation in engineering.

Thank You & All the best!

Hii aspirant..

Yes you can surely do computer science engineering after doing your diploma in Computer Engineering. You will have to take your admission through lateral entry and and your course of Engineering will be of span of three years.

For getting admission in computer science engineering after diploma you have to get 60% marks in diploma after high school or intermediate.

And at the end of 3 years your engineering degree will be equivalent to B tech degree.

Hope it helps. 

Best of luck for your future.
