A network hub absconds with any stateful packet inspection (SPI), so it won't act as a firewall.
Network hub can be shared with your home or office and also serve as a router too
A router allows communication between two different networks. A hub just links devices in a network.

Yes, switch as well as hub and router are network devices.
This is actually just a modem. A hub is a device with multiple ports for connecting computers to each other. A hub is now rarely used as a network switch is a faster more reliable device. Confusion comes from people like BT who supply what they call a home hub, which is actually a wireless router, they use the term home hub to refer to the central point (as in hub of a wheel) connection, probably because it's bright young designers never heard of a network hub! A modern wireless router normally consists of a combined router, 4 or 5 port network switch and wireless access point in one, and a non wireless one is the router and network switch Mohammad Talha 009746411902
Security between networks is implemented in an intermediary device (a router or firewall appliance) at the perimeter of the network. The firewall function performed by this device permits only known, trusted data to access the network.
In a star topology, all devices are connected to a central hub or switch, which manages data traffic between them. When integrating with other topologies, such as bus or ring, a router can be used to connect different network segments, allowing communication across diverse network structures. The central hub or switch facilitates easy management and troubleshooting, while the router enables data routing between multiple topologies, ensuring seamless connectivity. This setup enhances network flexibility and scalability.
Unfortunately, a hub isn't a router so you won't be able to get wireless Internet from one.
A router, switch or hub can be at the center of an ethernet network.
