I don't think it has to be anymore than 2, but it can be quite a few. The problem with a hub say for a computer like a usb hub is that each device receives less power and they are all sharing the same port, its like hooking 5 computers to one modem.
Switch is faster than HUB. If you are using managed switch you can create VLAN, you can secure ports and many other things.
Most of the time, a switch will send information only to the destination, while a hub will send to all of its ports. That makes the hub inefficient - in a hub, only one computer can transmit at a time.Most of the time, a switch will send information only to the destination, while a hub will send to all of its ports.

It depends on how many ports are on the hub. Some might have 4 ports, some might have 8 ports some might have 16 ports etc...
A switch. Each port has a separate path to each of the other ports on the switch. On a hub, all the ports are tied together into 1 single port. Think of a switch as an 4 lane freeway with 8 entrances and exits; a hub is a one lane highway with the same 8 entrances and exits. It can pass data from only one port to another port- switch can connect 4 ports to the other 4 ports (or 8 to 8 or 16 to 16, you get the idea) A switch is quite a bit more complicated AND is generally more expensive: between 20% and 300% more than a hub with the same number of ports BUT it's very useful on a busy network (business especially.)
In regards to the average usb port hub and how many ports are available, this can vary. The average usb port hub can support up to four usb inputs at a time.
Hubs and Switches make 1 ethernet connection out of as many is on the hub or switch.

Up-link ports are used to "Up-link" a device to another device such as a hub, router, or switch. Normal ports are used to attach a device to the before mentioned devices. A lot of devices have "auto configuration" or auto-sensing ports. With these auto sensing ports, any port can be utilized as a up-link port. In the early days of networking, you had to use a crossover cable to up-link a device to another switch, hub, or router. This was before they had up-link ports.
Simply plug into your network and share 4 USB ports.
You will see an "X" on many of the switch and hub input ports, indicating that this is a crossover connected input. This means that transmit and receive pairs are internally swapped to maintain proper signal alignment of the TX and RX pairs.
A hub, a switch, a router. They are all what you have described. A hub is a central point of a computer network. A switch is a series of ethernet ports with no wireless functionality. A router can have both wireless and wired capabilities, but can also have a modem built in.
Since Hubs are Physical-layer devices and do not segment collision domains (which switches do), the answer is "one". Since switch DO segement collision domains, a switch can pass as many frames as it has ports.
