A port is the interface through which external devices connect to a computer. It allows communication between the computer and peripherals such as keyboards, mice, printers, and external storage devices. Ports can be physical (USB, HDMI, Ethernet) or virtual (software-based communication channels like network ports).

External devices are used for storage just like internal devices but with the added bonus of being portable and not requiring space inside your computer. This usually comes at the sacrifice of access time or write times. Depends on the interface used for the external device.

The port is an external connection device on the computer which is used to connect different peripherals. Concretely it is a socket (and the corresponding plug) that enables an external device (peripheral) to be attached to a computer (usually to a motherboard or adapter card).
Expansion Buses are used to connect devices to the motherboard and therefore allow the flow of data between that device and other devices in the computer.

A parallel connector, or parallel port, is an interface used to connect a computer to some external peripheral. An example of things that can hook up to a computer using a parallel port include a printer and/or a scanner. More recently, the USB interface has become extremely common and most types of devices that used to commonly hook up via parallel port now hook up by USB instead.
The RS 232 interface is one of the standards used in serial communications. It uses serial signals (as opposed to parallel) to connect computers to devices like printers and modems.
It's used to connect to a serial device to a computer. The term "serial board" usually refers to an electronic printed circuit board that can be plugged into a computer, in order to attach an external device via a serial interface. In the past, the most common type of serial interface was RS-232, this was used to connect all kinds of devices to computers, most notably modems. These days, RS-232 has been replaced by USB, which stands for Universal Serial Bus.
SCSI stands for Small Computer System Interface. It is a set of standards used by computer engineers to physically connect and transfer data between computers and other devices.
