There have been many advancements in technology that have made significant impacts on society and the way things are done. One of them is in the field of communication. Although the invention of the telephone alone made communication faster than stage coach, trains, and the postal service, which were in use at the time, the telephone has now become a mobile device such that people can be reached by phone anytime and nearly anywhere.
Mobile phones work by connecting to cellular networks that are mobile network operators. Using cellular networks, calls between mobile phones and other mobile phones or land line phones are seamless, enabling a person using a mobile phone to move over wide areas while talking.
Advances in mobile phones have made them more than simply telephones by adding features such as text messages, email, Internet access, cameras, small applications, MP3 players, and GPS. These phones with advanced computing abilities are known as smart phones.
Another advancement in technology that has greatly changed the way society operates is the World Wide Web or the Internet. The Internet brought along with it the development of electronic mail, web-based applications, and inter-linked hypertext documents containing a wide range of information. Traditional communications media such as music, film, and television are changing and being redefined by the Internet. Web sites and blogging have changed the way newspapers, books and other print media get their information out to the public. Many have added or even replaced their print media with web-based sites where the same material can be read for less or even for free. Human interactions have changed with the introduction of electronic mail, instant messaging and social networking. Shopping has gone online and been a boom to both major retail outlets as well as smaller establishments. Any question, no matter the topic, can be easily and simply answered using the Internet.
