Email, in my opinion is key to changing the way we communicate. With only have one email address, we can follow the various models of communication on the Internet. Some models of communication, including:
1. Forum
2. Mailing List / Group
3. Social networking site
4. Blogs
5. File sharing site
6. E-learning using a teleconference

Let’s discuss one by one sixth above communication model.

Forum

The forum is an online discussion forum that discusses a particular themes or topics. Some portal sites or websites of a vendor product, usually provides a forum on their website. This forum can only be followed by visitors who have registered on the Web. If not registered, visitors web forums, can only read the results of discussions that already exist, but they can not make comments on the forum.

Registration form to become a member of this forum, normally requires us to fill in your email address, user and password to verify our membership. Activation code usually sent via email.

The famous example of a web forum for Delphi programmers in Indonesia is http://www.delphi-id.org. In this forum every member can make a topic to be discussed or answer / make comments on topics other people.

I felt the benefits to follow this forum. Especially when we have difficulty in making the case of certain programs. Then we can ask through this forum. With us to post our problems on the forum, surely many of the member who will read and provide solutions to our problems. In this Delphi forum, actually posting a comment / answer overseen by moderators, so that it does not deviate from the theme of this forum is Delphi.

But there are some forums that it is less useful. For example there are forums on the web portal seconds which sometimes raise the topic less educated. For example as I recall, I never read one of the topics in a second forum is “How do you feel when you first kiss?”. I think the topics are less than helpful. Therefore, because of the many forums that exist, then we must be really smart to choose and know exactly what the main themes and objectives of the forum.

World Telecommunications VoIP technology has given birth. Voice over Internet Protocol (also called VoIP, IP Telephony, Internet telephony or Digital Phone) is the technology that allows voice conversations remotely over the internet. Voice data converted into digital codes and flowed through the network that sends packets of data, rather than through traditional telephone analog circuits.

Definition of VoIP is a voice that is sent via the internet protocol (IP).

The simplest form of VoIP systems, two computers are connected to the Internet. The basic requirements to hold a VoIP connection is a computer connected to the internet, have a sound card (sound card) which is connected with a speaker and a microphone. With the support of specialized software, both computer users can connect the VoIP connection to one each other.

Form of this relationship may be in the exchange of files, sounds, images. The main emphasis for the VoIP is the relationship both in the form of sound. If both locations are connected by large distances (between cities, between countries) then it could be seen benefits in terms of cost. Both sides just enough to pay the cost of internet pulse alone, which usually will be cheaper than the cost of telephone long distance and international.

In its development, VoIP connection systems evolve. Developing any form of equipment, not only in the form of interconnected computers, but other equipment like a regular telephone connected to the VoIP network. Digital data network with a VoIP gateway to allow dealing with analog PABX or regular phone network. Communications between computers on the plane (extension) in the office is possible. Just a form of communication rather than voice alone. Can be shaped article (chat) or if the network is large enough can be used for Video Conference. In a further form of communication is better known as IP Telephony, which is a form of multimedia communication as a form of personal communication continuation of sound (VoIP). Flexibility of VoIP in the form of networks, equipment and communication media to make VoIP become quickly popular in public.
