The correct answer is: A. server
A network operating system (NOS) is a software that runs on a server and manages the resources on the network. It provides a platform for applications to run on and allows users to access shared resources such as files, printers, and databases.
A NOS is responsible for the following tasks:
- Managing the network’s resources, such as files, printers, and databases
- Providing a platform for applications to run on
- Ensuring that users have access to the resources they need
- Securing the network from unauthorized access
There are many different types of NOSs available, each with its own strengths and weaknesses. Some popular NOSs include Windows Server, Linux, and macOS Server.
The choice of NOS depends on the specific needs of the network. For example, a small business may need a simple NOS that is easy to use and manage, while a large enterprise may need a more complex NOS that can handle a large number of users and resources.
Here is a brief explanation of each option:
- Option A: Server. A NOS runs on a server, which is a computer that is dedicated to managing the network. The server provides a platform for applications to run on and allows users to access shared resources such as files, printers, and databases.
- Option B: Every system in the network. This is not correct. A NOS does not run on every system in the network. It runs on a server, which is a computer that is dedicated to managing the network.
- Option C: Both server and every system in the network. This is not correct. A NOS does not run on both the server and every system in the network. It runs on a server, which is a computer that is dedicated to managing the network.
- Option D: None of the mentioned. This is not correct. The correct answer is A.
