What is a primary advantage of using a network operating system?

A primary advantage of using a network operating system is that it facilitates centralized network management. This means that administrative tasks, such as user account management, security protocols, and resource allocation, can be managed from a central location rather than on individual computers. This centralized approach allows for easier monitoring and control of the network, ensuring that resources are efficiently utilized and policies can be uniformly applied across all devices in the network. Centralized management not only simplifies network administration but also enhances security by allowing for consistent updates and monitoring of potential threats.

The other choices suggest outcomes that are either negative impacts or not primary functions of a network operating system. For instance, decreasing network speed goes against the purpose of such systems, as they are designed to manage resources and traffic efficiently. Enhancing the capabilities of individual computers is more about the operating system running on each machine rather than a function of the networked environment itself. Restricting access to only remote workers is a limitation rather than an advantage; effective network operating systems are designed to support a range of access scenarios that can include both local and remote users.
