SD means self destruct
An "SD card" is a Secure Digital memory card.

I assume you mean CARD instead of port; an SD port and an SD slot are essentially the same thing. The answer is that you don't. You can, of course, get an SD card reader that plugs into a USB port.
The empirical rule is 68 - 95 - 99.7. 68% is the area for +/- 1 standard deviation (SD) from the mean, 95% is the area for +/- 2 SD from the mean; and 99.7% is the area for +/- 3 SD from the mean.
Self Defense
No.

The numbers must be greater than (mean - 2*sd) and laess than (mean + 2*sd).
