Final answer:
A Network Operating System (NOS) offers better security and centralized data management compared to a Disk Operating System (DOS), advantages which are critical for the needs of a growing small business.
Step-by-step explanation:
Two advantages of installing a Network Operating System (NOS) rather than a Disk Operating System (DOS) for a small business can be identified. First, a NOS provides better security features, such as user authentication, encryption, and access control, which are essential for protecting business data. Additionally, with a NOS, small businesses benefit from centralized data management, which makes it easier to store, share, and backup critical business information from a central location, enhancing collaboration and data integrity.
On the other hand, while a DOS may be seen as more cost-effective and user-friendly, these benefits are often outweighed by the operational efficiencies and advanced capabilities provided by a NOS, especially as the business grows. It is assumed that the small business in question values data security and the ability to easily manage and share data between employees.
