to identify the precise location of any place on earth
The grid system allows people to accurately pinpoint locations in terms of "degrees", which are then pinpointed more by units called "minutes".
In an electrical power transmission system: the grid is what the feeder feed into.

National grid is nothing but a net work (power system) of many different generation points across a region / country to feed to different end user points.

Well it's not really a grid it's lines of longitude and latitude so you can find the coordinates of whatever.
a global grid
So you can be told a point on a map and know where to look quickly instead of scanning the page! x
its either by studying landforms, the grid system, lines of latitude, or photos taken high above earth.

Because geographers are sexy.. ;)
Geographers use maps because that's what geographers do for a living. Geographers use maps to learn about the Earth's surface. That is their job.
geographers use computer-based systems called what to connect information with locations.

Geographers (those who study weather/land/people) usually do not often need to use a coordinate grid. However those studying geometry (a branch of maths) do use them.
