Secure Digital Card

A Secure Digital (SD) card is a removable flash-memory storage device used to save and transfer digital data, including records generated during behavioral research. It stores information in nonvolatile NAND flash cells, while an onboard controller manages data organization, error handling, and communication with a host device; some cards also provide a physical write-protect switch, although this is not the same as encryption. In behavior studies, SD cards can support portable data collection by recording video, audio, sensor measurements, or task-related files for later analysis. Their capacity, portability, and compatibility make them useful for moving experimental data between field equipment, laboratory systems, and archival storage.

The Security Market Line (SML) is a fundamental concept in finance that illustrates the relationship between an investment's expected return and its systematic risk, quantified by beta. This graphical representation helps investors understand how securities are priced based on their inherent risk levels and provides a framework for evaluating investment opportunities. The SML's slope, defined by the market risk premium, indicates the additional return investors require for taking on higher risk.
