The Types of Phones Essay Example for Free
The Types of Phones Essay The telephone is one of the best and most effective ways to communicate with people who are far away from you. It is a common household device used to transmit and receive sound by sending electronic signals through a network. The invention of the telephone basically revolutionized the mode of communication among people from different places in the world as it basically overshadowed the earlier ways of communicating such as snail mail. à à à à à à à à à à à However, the vast improvement of technology over the past decade or so gave rise to new types of phones that are being used by people in most parts of the world. These include the car phone and the mobile phone, which can be further classified into analog phones and digital phones. The introduction of the car phone is possibly one of the first significant developments in phone history. Basically, it provided convenience to people who are not at home most of the time and are unable to answer calls from the telephone. However, the boom of mobile phones basically made the car phone obsolete as the latter proved to be more effective and accessible when communicating with other people. Like the telephone, a mobile phone basically can also make and receive calls. It can be classified into two types, namely the analog phone and the digital phone. à The analog phone was the original type of mobile phone. Its size is relatively larger compared to its digital counterpart and its sound, image, and data transmission is done through a continuous signal flow which varies in phase and amplitude, among others. The disadvantage of an analog phone is that is slower in transmitting signals than the digital phone. However, it is more efficient than its digital counterpart when it used in other countries. à On the other hand, digital mobile phones transmit sound, images, and other types of data through a service provider that receives these data and retransmits it to another mobile phone. In addition, digital phones can also send instant messages through a system called Short Messaging Service (SMS) which is now commonly known as text messaging. Moreover, due to the rise of technology, certain digital phones also enable users to access the internet, take pictures, send email, shoot videos, and listen to music, among others. Some digital phones also have the capability to send images and other information through a wireless feature called ââ¬Å"Bluetoothâ⬠and ââ¬Å"Infraredâ⬠provided that the recipient also has these features. Furthermore, unlike analog phones, the digital phone transmission data faster to other mobile phones as there are usually multiple network providers. Using digital phones, SMS messages can be sent in a matter of seconds. However, a digital phone is not suitable for use especially when traveling to other countries since the network or service provider may not be compatible with the phone or may not be available in the area. Today, while the standard telephone still remains as a standard and necessary device in any home, the continuous surge of technology has made mobile phones almost a necessity than a luxury for almost everyone in the world.
