PHY is an abbreviation for the physical layer of the OSI model and refers to the circuitry required to implement physical layer functions. A PHY connects a link layer device (often called MAC as an abbreviation for media access control) to a physical medium such as an optical fiber or copper cable.
The term pH refers to a numerical measure of the acidity or alkalinity of any solution. pH values typically vary across a scale from 0 to 14, with the pH of neutral solutions equal to 7, increasing values have increasing alkalinity and decreasing values have increasing acidity. The pH of the vagina corresponds to the secretions continually produced by the vaginal walls.
