Mobile phone is an electronic device which is moveable
from one place to another. It is based on radio wave. The sending option
has the capacity to transform voice tone into electronic wave which is
taken by another device and transform into the sound instantly and then
the communication goes on. It is the gift of science. Now it is said
that the world is in fist of a human. It has some advantages as well as
disadvantages. Now it is not needed to go out for ring. Everybody who
has a phone can call others from their own place. It lessens our
tension. Once we had to wait a week or half of month for news from home
and abroad. But now in every moment messages are available from required
person. So it is said that mobile creates revolution in communicative
sector.
