Question 4 (SO 4, AC 1, AC 2, AC 3, AC 4)

To test the installation and configuration of the multi-user networked operating system, the following steps can be taken:

a) To verify that the system software functions according to the manufacturer's specification, the following tests can be performed:
- Ensure that all users are able to log in and access the network resources.
- Test the file sharing capabilities to ensure that users can share and access files across the network.
- Check that any security features, such as user permissions and access controls, are working as intended.
- Test the system's ability to handle multiple users simultaneously without crashing or slowing down.

b) To ensure that the test procedure meets the manufacturer's guidelines, refer to the manufacturer's documentation for specific testing procedures and follow them accordingly. This may include running specific diagnostic tools or performing certain tasks in a particular order.

c) To verify that the system software functions in the specified environment, test the system in a variety of scenarios that mimic real-world usage. This may include testing the system with different network configurations, different hardware setups, and under varying levels of user load.

d) To ensure that the system software communicates with the hardware and other application software according to the installation specification, test the integration of the operating system with any hardware devices and third-party software applications. Make sure that all necessary drivers are installed and functioning correctly, and that the system is able to communicate with external devices and software seamlessly.
