The Effects of an Invention or Innovation in Modern Life (final)

      In these twenty years, many technology products have been invented in the application of human life. The main purpose of these products is to hope that our lives will be more convenient and more efficient. The invention of cell phones has turned traditional wired telephones into a movable and wireless way of communication. This invention brought us a lot of convenience, for example, in work and in contact with our friends and families. Now we can also see mobile phones in our daily lives are equipped with more and more applications. It not only can make a phone call but also can take pictures, function as a mp3 player, connect to the Internet, and so on.

      The main advantage of cell phone is its immediacy. When I need to make a phone call to someone, I do not need to spend time looking for an outdoor public telephone or an indoor telephone. As long as I have a cell phone, I can directly call my friend or family. Another advantage of cell phone is that we no longer need to remember phone numbers. Because most cell phones all provide telephone book function, through a simple search, we can get the phone number that we need right away to make a phone call, or we can write a text message through cell phone and then send it to another cell phone. These two communication methods are very popular now.

      In addition to calling features, another advantage of cell phone is that it has many additional features. For example, with a calendar function, we are able to record an important thing and when to do something, and we can even set an alarm to remind ourselves. And now most cell phones also combine music players, USB flash drives, and digital cameras inside. So when you need to listen to the music, or sometimes need to transfer computer files to another computer, or temporarily need to take photographs, you do not need to carry a MP3 player, a USB flash drive, a digital camera with you, as long as you have a cell phone that has the wonderful above-mentioned features, you can fulfill what you want to do.

      Finally, some cell phones even provide an access to the Internet. The technique of wireless communications allows us to use the Internet more immediately and more conveniently. Even in the outside, you can still use cell phones to receive your mails, book tickets, browse the WWW and so on.

      Although cell phones have many advantages, but in fact they still have some disadvantages, for example, a long-controversial topic such as "the impact of electromagnetic waves to the brain," which is not yet confirmed. Because mobile phones are used through wireless communication channels, and wireless communications model is the use of electromagnetic waves by transmitted calling information, some scholars believe that the electromagnetic waves generated by the magnetic field will affect the human body. Another disadvantage is that we can be easily contacted through cell phone, especially when you want to enjoy the holidays. If cell phones often ring, you might lose the holiday mood. In this digital age, in the future the control of Information Appliances(IA:資訊家電) is intended to integrate the functions of cell phones, at that time application of mobile phones will be more widespread and it will certainly bring to our lives more convenience.
