BCOM INFORMATION SYSTEM MANAGEMENT and BCOM COMPUTER APPLICATION both are three year UG courses. Both the courses have employability. Information system management is a IT skill to manage data and to sequence it in terms of data entry and data management. Also Computer Application will lead you to jobs in Accounting, Advanced IT etc.

For both the courses you have the same area to work on and most of the employers employ both the course pursue for same JD. I would recommend that BCOM COMPUTER APPLICATION will be more helpful for you in order to get job.
