The advent and rapid development of the Internet technology brought significant changes to various disciplines of our lives. Before, telegraph and telephone services are the only means of communication especially for individuals who have relatives or friends working or residing on other parts of the world.

The farther your friend or relative you want to keep in touch with, the more that cost that you will incur (expensive long distance call rates). However, with the advent of Internet technology, you will be able to make unlimited long distance calls to your friends and relatives abroad through the VOIP or the Voice over Internet Protocol Services or even see and talk to them through free messaging services on the Internet. All you need to have is a personal computer and high-speed Internet connection and you are now off to keep in touch with your loved ones.
