In brief: Covers UVA and UVB

These days, majority of the sunscreens on the shelves are broad spectrum, covering both uva and uvb.
The physical blocks contain zinc or titanium, which covers all of uvb, and small range of uva spectrum. The chemical blocks contain avobenzone, oxybenzone and it's derivatives. Newer chemicals such as mexoryl and helioplex are good longer-lasting uva blocks.

In brief: Both UVA & UVB ++++

In the past, a broad spectrum antibiotic essentially covered both uva and uvb wavelentghs.
However increased knowledge about the effects of the sun on the skin and health have made this appear to be a limited definition. Broad spectrum essentially means covering all the various wavelengths.
