Do mobile phones affect your privacy?

Nowadays life is unthinkable without a mobile phone. Wherever you are, you see people talking on the phone, playing, messaging, listening to music, watching videos, reading the news, surfing... Do you want to know more about mobile phones and how they have changed our lives? Then, answer the following questions.

1. How have mobile phones changed in the last 30 years?
- First Generation technology: the first mobile phones, referred to as First Generation or 1G, were introduced to the public market in 1983 by the Motorola Company. These first mobile phones used analog technology which was much less reliable than the digital technology we use today. The analog phones also had a great deal more static and noise interference than we are accustomed to today. The first mobile phones during this era were confined to car phones and they were permanently installed in the floorboard of automobiles. After a few years, they became mobile and consumers could take the phones with them outside of the car. However, they were the size of a large briefcase and very inconvenient. These new mobile phones were also rather expensive.
-Second Generation technology: in 1990, the first cell phone call was made using the new digital technology that became characteristic of this era and cellular phone technology was faster and much quieter than its analog predecessor. The new technology also made them capable of being smaller rather than the large briefcase-sized units.
-Third Generation technology: or 3G, is what many people currently use in their digital cellular phones today. This technology is capable of a lot of things. These capabilities have helped to increase the amount of sales and the popularity of these new phones
