Omnipresence of information and Communication Technologies in contemporary lives and workplaces makes Computer Science a sought after area of study, vocation and research. Established in 1984, the Computer Science Department of Miranda House is one of the youngest departments in the college. The department has a spacious laboratory with more than thirty five computers connected in a LAN, fully supported by Open Source Softwares. The department also maintains a well-stocked library of Computer Science books.

The department frequently conducts talks, seminars and workshops for its students including those on Personality Development and Soft Skills Enhancement to help the students have an edge when they venture out in life. To keep pace with latest subjects and technologies, students are encouraged to participate in Massive Open Online Courses (MOOCs).

The department has a technical society, CompuAda named after Lady Ada Lovelace, credited with writing the first algorithm for a computer in 1840. CompuAda holds a yearly inter college event, Orrey, which sees large participation from students from within and outside Delhi.

The Department can boast of a large number of alumnae working wonders in technology and management.
