1 INSTITUTE OF AERONAUTICAL ENGINEERING Dundigal, Hyderabad COMPUTER SCIENCE AND ENGINEERING TUTORIAL QUESTION BANK Course Name : SCRIPTING LANGUAGES Course Code : A80537 Class : IV B. Tech II Semester Branch : Computer Science and Engineering Year : Course Faculty : E. Lingappa Assisstant Professor, P. Sunil Kumar Assisstant Professor OBJECTIVES The course demonstrates an in depth understanding of the tools and the scripting languages necessary for design and development of applications dealing with Bio- information/bio-data. The instructor is advised to discuss examples in the context of Bio-Data/Bio-information application development. In line with this, Faculty of Institute of Aeronautical Engineering, Hyderabad has taken a lead in incorporating philosophy of outcome based education in the process of programming skills and career development. So, all students of the institute should understand the depth and approach of course to be taught through this question bank, which will enhance learner s learning process. S.
