1. Typically organizations uses private networks which is not accessible by outside world only people within the organization can use the netwok. There are N numbers of people within the organization and not all the people should share the same data in other words data access should be restricted in sone extent. To acheive this once can use Hub in which group of people can be created. The data shared to a group is only accessible to those people who reside within that particular group. The type of hub that I recomend is Intellegent hub as it enables administration monitor system to get control over the network. In time when new people may be added to groups can be acheived easially by hub configuration.

4. Managed switches have more capability than unmanaged switches but also require a skilled administrator or engineer to make the most of them. A managed switch allows you have better control of your network and all the traffic moving through it. An unmanaged switch allows Ethernet devices to communicate with one another automatically using auto-negotiation to determine parameters such as the data rate and whether to use half-duplex or full-duplex mode.

5. The Instance in which unmanaged switches csn be used is when there is no restriction over the network and anybody can access the network withot monitoring.
