In the case of equity options, a "one-unit move" in the underlying would be a $1 change in the price of the stock. In general, deep in-the-money call options have a delta close to 100 (1 x 100 shares), at-the-money call options have deltas near 50 and deep out-of-the-money call options have deltas close to zero. Put options behave the same way, except they have negative deltas
