06. A Mobile Phone
(a) What is a mobile phone?(b) How has science changed our life?
(c) Which mobile companies are remarkable in Bangladesh?
(d) For whom are mobile phones necessary?
(e) How can the criminals use the mobile phone?
The mobile phone is one of the latest editions of modern communication technology.
It is handy and portable as the term 'mobile' signifies. It is a small telephone that can
be carried in a hand or pocket. The effective speaking range of man is only a few
yards. But with the help of mobile phone he has increased the range to hundreds of
miles. Is it not a miracle that a man walking along a street or riding on a vehicle can
speak to his friends or relatives hundreds of miles away? A man traveling a distant
part of the land is talking to his friends or relatives at home. And all these are done at
a nominal cost. There are many mobile companies in our country. The Grameen,
Robi, Bangla Link, Tele Talk, Airtel and City Cell are remarkable. These companies
are providing the service to the customers, but their cost is not still at the range of the
common people. In comparison with other countries, we see that they are very much
expensive. A lot of world class companies are now manufacturing mobile sets. A
mobile phone is very useful to important persons such as politicians, artists, doctors,
businessmen and high officials. But like all other gifts of science it is not an unmixed
blessing. The mobile phone is a useful instrument and it can be used by both good and
bad people. The police can use it in maintaining law and order and detecting the
criminals and the criminals can make use of it in committing crimes.
