Explanation:

1. In binary code, each digit represents a bit. A bit is the basic unit of information in computing and digital communications, having two possible values (0 or 1).
2. The Internet became widely accessible in the 1990s. It enabled sharing of information, communication, and access to a vast amount of resources, which made personal computing more useful and thus spread it in homes and businesses. Smartphones became prominent later (2000s - 2010s), integrated circuits and microprocessors were developed earlier (mid - 20th century).
3. Wearable computers like smartwatches are commonly used for monitoring health (e.g., heart rate) and tracking physical activity (e.g., steps taken). Running complex simulations and performing large - scale data processing are usually done by more powerful desktop or server computers. Hosting websites is typically done by web servers.

Answer:

1. A. A bit
2. B. The Internet
3. C. Monitoring health and tracking physical activity
