How to use a microSD card reader with SCK instead of CLK?

Question

I've bought this microSD reader/writer: http://www.ebay.com/itm/131132034753

I've found only one tutorial, where the pins are similar to my pins, but in the example there is a CLK instead of SCK: https://learn.sparkfun.com/tutorials/microsd-shield-and-sd-breakout-hookup-guide

The pins on my MicroSD reader are:

CS
SCK
MOSI
MISO
VCC
GND

SCK is actually a clock signal. So basically, they are the same thing here. — Ikbel, Nov 16 '15 at 22:42

SCK stands for SPI ClocK

CLK stands for SPI CLocK

Two different acronyms for the same thing.

It's common practice for speakers/writers to use the generic term: "clock" (CLK) for various different situations. This clearly being a serial interface we don't need to specifically say Serial cloCK each time the signal mentioned, as it's more of a mouthful than saying "clock".

In this case consider "CLK" and "SCK" as fully interchangeable.
