What is not a disadvantage of an in-house microcomputer network?

The answer highlights that data sharing is not a disadvantage of an in-house microcomputer network. In fact, one of the primary advantages of an in-house network is the ability to facilitate effective data sharing among users. With a microcomputer network, various devices can be interconnected, allowing for easy access to files, applications, and resources. This promotes collaboration and efficiency as employees can share information quickly without the need for external storage or communication methods.

In contrast, keeping the system up to date, requiring a network manager, and facing initial installation costs are all inherent challenges or disadvantages associated with managing an in-house network. Regular updates and maintenance can be resource-intensive, a network manager incurs additional staffing costs, and the initial setup involves considerable investment in hardware and software. These factors can complicate the management of the network. However, the capability for seamless data sharing serves as a strong benefit, outweighing these potential downsides related to the network's operation.
