Step-by-step explanation:
The term for the requirement to access a library using a computer and internet access is an Internet Connection. Although both hardware, which includes the physical computer, and software, the programs and operating systems that make the computer function, are necessary components, the specific requirement highlighted here to access library services is an internet connection.
