A center connectivity device means a star topology is being used. If it is a managed hub such as a MAU or MSAU unit, then it is a token ring network.
For a ring topology each client device is usually attached to a central hub, which is a managed hub, called an MAU or MSAU unit. It contains a grid that manages the electrical portion of the ring.

A router allows communication between two different networks. A hub just links devices in a network.
Network hub can be shared with your home or office and also serve as a router too
A network hub absconds with any stateful packet inspection (SPI), so it won't act as a firewall.
The difference is in the way how they process communications between two or more computers. If you send some information to one computer only using hub it will resend the information to all computers in the network. When switches resend information to the only one computer.
a hub is a central point in a network through which all the wires pass, a switch connects more than 2 LAN networks
