Switch work's full-duplex mode, but HUB work's on Half-duplex mode. each port of switch is a different collision-domain, but HUB is single collision-domain.
USB ports transmit data to up ti 127 devices in a daisy chain.
ports are important because through which goods are imported and exported.
To switch frames between different ports
just connect the switches in a star shape and connect your machines to the "edge"-switches.You've one "core"-switch which uses 4 of it's 8 ports to connect to the other switches. These edge switches have 7 ports free for machines.4x7=28 plus you've 4 ports free on your "core/center"-switch, makes 29(+3)
VLANs.
There are typically 5 to 24 ports on a network switch, though real high end switches can house more. Internally the ports are connected with copper wires.
A firewall is what opens ports to allow devices, apps or anything to transmit anything

Serial ports transmit data one bit at a time, which is why they are becoming obsolete.
The minimum number of ports on most brands of switches is four. While there is no industry rule that limits the number of ports on a single switch, practical application has shown that a minimum of four ports is about right.
