LAN Operating Systems Scenarios
Read the three scenarios below and answer the questions that follow each scenario.

1. You are the network administrator for a new company that has 10 users and that plans to add 5 more users within a year. The files need to be accessed by all 10 users, and each user must have different security rights.

What kind of network would you install? How would the pieces and components of this network relate to each other? Define each component.
For this scenario, I would install a Server/Domain-Based Model. It provides central control over the network resources by creating an environment that users can log into by using a single set of credentials that is maintained by the server. They can handle many logons and requests for shared data.

Domain – Collection of users and computers whose account are managed by domain controllers
Domain Controllers – Server that handles all the security requests from other computers and servers within the Windows Server domain.
Directory Service – Services that help network devices locate service providers.
Network Information Service (NIS) – Protocol for the administration of network-wide databases. Essentially uses two programs: one for finding a NIS server and one for accessing the NIS databases.

2. You are the network administrator for a company that has a peer-to-peer network.
How would the pieces and components of this network relate to each other? Define all the components of this type of network.
Each computer on the network can communicate with each other directly, and they do not have a central computer that monitors and controls the communication on the network. Each computer in the network is called a node. The owner of each computer partitions part of their power to be used directly by the other node(s) on the network. A basic peer-to-peer network is illustrated below:
