Any port in a storm refers to a ship on the high seas. It definitely doesn’t apply to input and output ports on PCs.

Most of the legacy ports have been around so long I’m pretty used to them. Mouse and keyboard (both the PS/2 type ports and the newer USB ports), VGA for the monitor, the fast disappearing parallel printer port, serial port (are there still any serial devices?), audio in and audio out port (and some ports I’ve probably missed).

My Dell Inspiron 530 threw me with another port, a DVI port. There were also two cables for the Dell SE198WFP LCD monitor, a standard VGA cable, and a DVI cable.
DVI is “a digital connector which is the ideal way to connect to an LCD monitor.”
DVI-I (Integrated) can carry both a digital and an analog signal to support VGA monitors, and DVI-D (Digital) provides only a digital signal. DVI was intended to replace VGA.

HDMI is backward compatible with DVI. HDMI carries both digital video and audio signals in a single cable. Most gamers would know about HDMI as the Xbox 360 Premium began shipping with a HDMI port last year.
