modern technology. For public and private vehicles, computer technology
usually helps to send alerts such as low fuel levels, light on/off,
automatic safety alarms, mechanical part errors, etc.
Uses of Computer in Navigation
Computers have changed the way navigation systems work. Instead of checking
the location on paper maps, we can easily check the entire world map on the
computer. In conjunction with GPS technology, computers also show our live
location or exact location on a map, nearest areas, and other navigational
elements.
The great thing about using the navigation on a computer is that we can also
see our real-time location on a map to see which direction we're headed.
Similarly, we can set the route on the map to go from one place to another.
