Invention of smartphones

Invention of smartphones - Development of a format that would cut the cost of long-distance phone calls - Standardization of VoIP - Development of GPS

1. Invention of smartphones

2. Development of a format that would cut the cost of long-distance phone calls
3. Standardization of VoIP
4. Development of GPS

To arrange the events in chronological order, we need to determine the order in which they occurred. Here's a step-by-step guide on how to do it:

1. Identify the events mentioned:
- Development of GPS
- Standardization of VoIP (Voice over Internet Protocol)
- Development of a format that would cut the cost of long-distance phone calls
- Invention of smartphones

2. Research the approximate timeframes for each event:
- Development of GPS: The development of GPS (Global Positioning System) began in the 1970s and continued through the 1980s.
- Standardization of VoIP: The standardization of VoIP took place in the late 1990s and early 2000s.
- Development of a format that would cut the cost of long-distance phone calls: It is unclear which specific format is being referenced. Various formats for cost-cutting long-distance phone calls have been developed over the years. Without additional information, we cannot determine a specific timeframe for this event.
- Invention of smartphones: The invention of smartphones dates back to the early 1990s, but they became more prevalent and widely adopted in the late 2000s.

3. Determine the chronological order based on the information obtained:
- Development of GPS: This occurred before the standardization of VoIP and the invention of smartphones.
- Standardization of VoIP: This occurred after the development of GPS but before the invention of smartphones.
- Development of a format that would cut the cost of long-distance phone calls: Without more specific information, we cannot accurately place this event in the chronology.
- Invention of smartphones: This occurred after the development of GPS and the standardization of VoIP.

So, the chronological order would be:
1. Development of GPS
2. Standardization of VoIP
3. Invention of smartphones

Note: The placement of the event relating to a format that would cut the cost of long-distance phone calls depends on the specific development being referred to, which is not specified in the question.
