Until the 1800s people used letters for communication. But this way was very slow, and people couldn’tcontact each other in emergency situations. There was also the possibility of letters being lost. But after the invention of the telephone in 1876 by Alexander Graham Bell, itbecame easier for people to communicate. Then in the 1970s, the cellular phone was invented. It brought many advantages into our lives. However, although cell phonesbrought many benefits into our lives, they also have disadvantages.
The most important advantage of cell phones is that they can be used almost everywhere withoutcables or electricity. By using a mobile phone, you can communicate with anyone whenever you want and wherever you are. Besides this, if there is an emergency situation, mobilephones can be useful. Furthermore, you can get access to the Internet by using a cell phone. These days, the world’s most common means of communication is SMS. Cellphones include this system, so in this way you can communicate with someone more cheaply than by normal calling.
In contrast, cell phones have some disadvantages. Forexample, cell phones spread electromagnetic waves. And these electromagnetic waves cause important health problems like cancer. Additionally, cell phones often affect theelectronic systems used by equipment like cars, ABS (automatic brake system), and computers. This can cause big problems, such as accidents.
To sum up, cellphones not only have advantages, but also they have disadvantages. Mobile phones make our lives easier. But at the same time, they cause some important problems in our health.
