PHI and PUE: scope additions, not located slides
Cram this first — memory hook
Protected Health Information = health information; Power Usage Effectiveness = power use; Personally Identifiable Information = identifying a person.
Exam trap
The slides support , but that does not prove your note meant . Keep both visible until the lecturer confirms.
The slide facts
No dedicated definition of or was located in the supplied text and image-slide extraction. These remain because the original scope explicitly names them; they are not silently substituted for .
If you have time — extra
Protected Health Information () is a health-privacy term concerning individually identifiable health information within the applicable framework, particularly the United States Health Insurance Portability and Accountability Act context. Health Insurance Portability and Accountability Act () is the expanded act name. Not every isolated medical fact automatically has the same legal status in every country or context. Power Usage Effectiveness () is completely different: it measures data-center energy overhead. Divide total facility energy by information-technology equipment energy using the same time period and measurement boundary. If the building uses 150 kilowatt-hours and the IT equipment uses 100, is 1.5. A value nearer 1 indicates less facility overhead per unit of IT energy. It is not a privacy-compliance score and does not alone measure the usefulness of computing work.
Walkthrough
For a calculation, identify the total and IT-only energy values, align units/time periods, and divide total by IT. For , identify the health-information and identifiability context without assuming a jurisdiction not stated.
