Terms used on the VIX dashboard.

VIX
Cboe Volatility Index: the market’s expectation of S&P 500 volatility over the next 30 days, derived from S&P 500 option prices.
F1
Front-month VIX future: the monthly VIX futures contract with the nearest expiration. F2 is the following month, and so on.
VVIX
Volatility of the VIX, derived from VIX option prices. High values indicate that large VIX moves are expected.
F1 − VIX
Difference between the front-month future and the VIX. Positive in calm markets (contango), negative when near-term stress is priced in (backwardation).
Term structure
Prices of the VIX futures across expiration months.
Contango / backwardation
Contango: later expirations are priced higher than earlier ones, typical in calm markets. Backwardation: later expirations are priced lower, typical in times of stress.
Roll-over
Expiration of the front-month future. Afterwards the next contract becomes F1.
