Mobile Phones الهواتف النقاله

This subject talks about definition, advantages and disadvantages of
mobile phones.

 

Mobile phone is a hand held device with built-in antennas
often called cell phone.

 

Mobile phones are seen as a modern invention,
but they are a development of something that dates back a long way.
The
biggest and most obvious change is the rapid take-up of mobile phones.
Twelve years ago, they were only for the wealthy, and had a “yuppie”
image.

 

Seven years ago they were still rare.

 

Now there are more mobile
phones than households and numbers are still growing fast.

 

We are
approaching the time when it will be considered unusual not to have a
mobile phone.
There are many advantages of mobiles.

 

They are
convenient to use i.e.

 

using it anytime you need to make a call, SMS can
be used when one can’t afford to call, enables one to send and receive
e-mail, They are portable e.g.

 

it can be carried from one place to
another.
But the disadvantages are that children’s skulls are
vulnerable to radio waves from phones which can damage their brain
tissues as the nervous system is very sensitive during development.

 

Cell
phone antennas which are close to earpiece are harmful to humans due to
large volumes of electro-magnetic waves that get concentrated around it
during the receipt and placing of calls.

 

Vibrating phones affect men’s
reproductive system, radiation from phones also increase blood-pressure,
risk of brain tumors mainly acoustic neuromas.

 

Lab research also shows
that long exposure to mobile phone on stand-by leads to serious
degradation of white blood cells.

 

They are susceptible to loss and
theft.

 

Restricting access to corporate data and applications.
Non-repairable internal corrosion of parts if wet.

 

Vulnerable to extreme
heat or cold which may cause momentary loss of screen display.

 

Mobiles
are very noisy sometimes especially when we are praying in the mosque,
learning at university, or reading in libraries.

Useful Modern Inventions in the Home(اهمية الاختراعات الجديده)

Life
today is remarkably changed compared to that of our forefathers’ time.
Take, for instance, new inventions in the home.

 

The rice-cooker,
pressure cooker, gas stove, electric oven, microwave oven, electric
toaster and food-processor are a great boon to housewives who find
cooking and preparing meals very much easier now than in the olden days.
Now time is saved because electricity cuts long hours of tedious work
and we find we can afford to spend more time on hobbies and other
activities.
The rice-cooker is a real time-saver and it is so simple
to operate that even a child of ten or so can handle it and dish out
perfectly cooked rice.

 

So are the other gadgets which save the housewife
long hours of labour.
Besides the kitchen gadgets, there are others
like the vacuum-cleaner for cleaning the house, the electric lawn-mower
for trimming the grmind and the washing-machine for washing the clothes.

Life for housewives today is more relaxing and they have more free
time to attend to their children or do reading, sewing, shopping and
visiting.
