Final answer:
While many modern systems do use mobile computers and GPS, not all information is accessed this way. Various sectors like agriculture and law enforcement have seen a considerable impact due to the advent of these new information technologies, facilitating data-driven decision-making and enhanced monitoring capabilities.
Step-by-step explanation:
The statement 'All information is accessed through dispatch or mobile computer systems' is not entirely true. While many modern systems, such as for law enforcement, transportation, and agriculture, heavily rely on dispatch systems, mobile computers, Global Positioning System (GPS), and Geographic Information Systems (GIS) for information access and data processing, not all information is solely accessed this way. There are still many instances where information may come from other sources, such as direct human input, printed materials, or other forms of communication that are not digital or computer-based.
Over time, technologies like the Internet, GPS, and GIS have had a considerable impact on various sectors by providing instant access to vast amounts of data, reshaping how decisions are driven. For example, American farmers who used to rely on the Farmer's Almanac and the Weather Bureau for planting and harvesting now use detailed data from these advanced technologies to maximize production efficiency. Similarly, the law enforcement sector has shifted to a digital paradigm where activities such as vehicle tracking are increasingly computerized, allowing for the monitoring of vehicular movements through the use of cameras and electronic toll collection systems that employ GPS tracking.
