USB (for Universal Serial bus
A common example is USB. The Universal Serial Bus interface is used to connect external (and occasionally internal) devices to a computer. Multiple devices are all connected to this one interface, and the electrical signalling on that interface determines which device or devices are in communication at any point in time.
Another example is the bus internal to the computer that connects the CPU to multiple banks of RAM and other internal components. While electrically very different than USB, the concept – that of connecting multiple devices to a single communication path – is the same.

If it’s “Enhanced”, it’s USB 2.0. If it’s not, then it’s USB 1.x.
Now, wasn’t that obvious?
Important: on most machines the presence of “Enhanced”, even only once (which it typically is), means that all USB ports are USB 2.0 ports. Typically a machine will have only one type of port
Port numbers are typically well defined. For example, by definition, a mail server will “listen” for incoming connections on port 25. When an attempt is made to connect to that server requesting a connection to port 25, that means that the machine requesting the connection wants to “talk to” the email server listening there, presumably in order to send mail.
There are hundreds of different pre-defined port numbers for all common services. Some common examples:
* http is port 80 and https is 443* Sending mail (SMTP) is typically port 25 and receiving mail (POP3) is port 110* ftp, or file transfer protocol, uses both ports 21 and 22.
One way of looking at port numbers might be to think of them as apartment numbers in a large apartment building.
The apartment building’s street address might be analogous to the server’s IP address, which locates the apartment building (server). Once at the front door, the apartment number (port number) locates the specific resident (service) you wish to talk to. If that resident (service) doesn’t respond, it might be because their door is locked (access blocked, perhaps by a firewall) or they’re not home (the service isn’t running).
Not all port numbers exist on all servers, because not all servers provide all possible services; that would be analogous to an apartment number that doesn’t exist at a particular address.

Port, when used in reference to hardware, is a physical connection to a machine.
A desktop computer might come with several ports, including USB ports, networking ports, display ports, and more.

The one exception to this scenario is a machine with USB 1.1 ports that has a USB 2.0 expansion card added. In this case I know of no way to tell which is which, other than simply knowing you added a USB 2.0 card to a machine with built-in 1.1 ports. Obviously in a case like this, the built-in ports are 1.1, and the added expansion card ports are 2.0. /no-time-for-caution-download.html.
