Final answer:
The statement is false; IT infrastructure encompasses a combination of both physical hardware and software components used to manage enterprise operations. High-voltage wires are not wrapped in insulating material; the air serves as an insulator.
Step-by-step explanation:
The statement "IT infrastructure consists of only those physical computing devices required to operate the enterprise" is FALSE. IT infrastructure not only includes physical devices but also comprises software applications, network resources, data management, and the services that are necessary to support the operations and management of an enterprise IT environment.
The infrastructural components are designed to work together to provide a stable and operational platform for both the hardware and software. This allows businesses and organizations to deliver IT solutions and services to its employees, partners, and customers.
Regarding the reference information provided about high-voltage wires, the correct answer is FALSE. High-voltage wires are indeed held aloft by insulating connectors; however, these wires are generally not wrapped in an insulating material. Instead, they are left bare because the air around them acts as an insulator, and wrapping them would be both impractical and unnecessary for the distances that power lines cover.
