Purdue has many different technology groups, some focused on specific operational goals, research, or academics. As a Krannert student, you will likely only ever deal with two groups on campus.
ITaP, which stands for Information Technology at Purdue, is the large central IT organization of the University. They handle the overall architecture and provide gloal services. Some examples of the services they provide are your Purdue Career Account, provide Office 365 email access, run the wired and wireless network, and run multiple labs across West Lafayette campus.
The Krannert Computing Center (KCC) is a dedicated IT group for the Krannert School of Management. KCC provides IT solutions for academic and research needs primarily for Krannert faculty, staff, and students. Some of their solutions, such as Video Express, are used by other units on campus.
