What is SI?

SI could refer to several technologies or concepts depending on the context. Without more information, it is difficult to provide a precise description. Some possibilities include: * **Signal Integrity (SI):** In electronics, signal integrity refers to the quality of an electrical signal. It ensures that the signal transmitted on a circuit board or cable is accurately received at the other end. Poor signal integrity can lead to errors and malfunctions. * **Système International d'Unités (SI):** This is the international system of units, the modern form of the metric system, and is the most widely used system of measurement. It comprises a coherent system of units of measurement built on seven base units. * **Strategic Intelligence (SI):** Strategic intelligence involves gathering and analyzing information to support strategic decision-making, often used in business and government contexts.
