Scenario: Two friends meet again!! Hey Dude! Look what I bought yesterday….An Android Smartphone!!! Samir said delightfully.

In fact, I wanted some help from you….. I wasn’t able to configure the Data Connection, GPS and Networking….I tried taking help from my Mobile Operator's helpdesk… but they too were unable to help after a point.

Why not! – Did you try using the User Guide/Manual ? I did, but I could not understand much of it!

– Samir replied sadly!!

Akshat explained, since today we have the power of PC in our hands, therefore we also need to configure & maintain our Smartphone, similar to what we have been doing for our PCs.

Very nice, so did you try those great apps, which I had shown you the other day!

Owning a Smartphone doesn’t make you that

Smart!!! Akshat blinked cleverly.

Global Positioning System

Now, wherever you go you can let your dear ones know where you are.

• GPS is actually a constellation of 27 earth-orbiting satellites. (24 in operation and 3 extras in case one fails)

• There are at least four satellites "visible" in the sky.

• A GPS receiver's job is to locate three or more of these satellites, figure out the distance to each, and use this information to deduce its own location.

• This operation is based on a mathematical principle called trilateration.
