Where can students access or purchase computers on campus?

Students at the University of South Carolina can access or purchase computers at several convenient locations on campus, which makes option C the correct choice. This option highlights not just the designated places where students can obtain computers, such as the Apple Authorized Campus Store, but also mentions the Gamecock iHub and the library's computer lab.

The Apple Authorized Campus Store allows students to purchase Apple products and provides resources for tech support, making it a valuable place for acquiring computers. The Gamecock iHub is a dedicated service and resource center for students, providing technology-related support, and the library's computer lab offers free access to computers for academic purposes, though it may not be a purchasing point. This variety helps meet the diverse needs of students, whether they are looking to buy a new computer or just need access for their studies.

This comprehensive approach not only provides students with options for purchasing but also includes accessible locations for using computers, thereby ensuring they have the tools necessary for their academic success.
