Why would your education be any less valuable because the school closed? Don’t other schools offer the same course or something comparable? Of course you can put it on your resume. Do so, and be proud.

Many people get their college degree years ago, and become lifelong learners and continue to keep up to date in their fields through continuing education and training. Most – if not all – employers practically require it. I would think this especially true in computer science.

I would continue putting your degree on your resume, and be proud of your accomplishment of graduating in any interviews you do. Enroll in school again, it will only help you.
