Final answer:
Features 2, 3, and 4 are correct: information can be stored, digital signals can be transmitted over long distances, and signal loss happens less frequently.
Step-by-step explanation:
Out of the given features, numbers 2, 3, and 4 are correct.
Information can be stored for future recovery. Digital signals can be transmitted over long distances, making them suitable for satellite-transmitted information and land-based long-distance transmissions. Additionally, digital signals experience less signal loss compared to analog signals. This allows for clearer data transmission and reduces the need for amplification or signal regeneration.
