IntroductionThe history and importance of the problem. At present, development of technologies and more, including the development of a system of communication that is fast. Modern. Communication is by sending a message to the recipients of the message have an intermediary in communication is communication because communication systems has developed a communication and therefore developed according to this development, and there are several factors causing. The first reason is that the needs of consumers who want to transfer data or message, faster more comfortable and other causes like bulletins notify call ambulance or emergency contact in more easily. In addition, we use the phone to contact each other in the current tools and other types of communication. Like a letter in the middle of a communication as a basic early communication. Because in the past have used the mailing address as another contact. Rather than go home to reduce expenditure on travel and contacts more comfortable. But not just that humans have developed communication tools, much more modern causes a type of communication tool called the Telegraph, which in the past has called the Telegraph as a modern communication tool. By using the short message is sent. Sri Krishna jewel joy (2547) is researching the country's communication systems in Thailand up to 2540 (1997) 2550 (2007) found that during the country's communication system is a Thailand we mail chat. Reliance mobile phones started coming together during their development since 2545 by a good communication. If compared to developing communication tools currently accounted for 20 percent of the current. The development of better technology, step into the digital age now which is considered the most modern in now and there are communication devices that provide newer phones from the original, such as the iPod Tablet computer will contact each other through applications like Facebook in addition to typing to find a Line that saw only the current message and talk to each other face-to-face or video. these reflect changes in communication that is based on the ages and needs. Therefore, this project has been made to reflect the evolution of communication. Modern and meet your needs. Finally, communication is a necessary and useful life. Therefore, should use the language correctly and politely asked suit time and place and era. Why they make the subject project. The study of communication and the communication tools in 2540 (1997) To 2557 (2014) In the countries of Thailand, because they want to know if there are any communication, which is a tool used to communicate about current tools used in that communication has a wide variety of both new versions of the many popular, such as mobile phones, where the mobile phone is a communication tool that is being developed, most especially the Apple company's Samsung mobile phones and communication tool that has been developed is a mobile phone and a mobile phone, it will still continue to develop gradually. Sasima blessing glass Moonstone (2550) is studying the development of communication technology of interest ศัพท mobile calls and the result is that the results support younger here.(B) multimedia amun Jeju Hotel anhydrous -here is the image amun ngok mountain.

That can communicate to each other the Puerto time directory in response to sleep record chachu (Real Time Interactive Communication). There are many communication tool for many things, tools that have been developed together is one of mobile phones or mobile phone is a device used in electronic communication, two way through. Mobile phones use radio waves to communicate with mobile phone network base stations by network through a mobile phone service provider, each is connected to the telephone network and mobile phone network address of another service provider. Mobile phones have increased in a manner portable computer to a smart phone, which is mentioned in the title, the development of tools and communication systems is what scientists think helps to develop a system of communication tools, which scientists have been involved in the study.Boplangngan magnetic waves of the world we can bring into, or brought to the making and development of tools which make the communication systems of the world, we have developed the past because scientists of the world, we are the best and will make our world is improving communication so that these things do make our world has to communicate with each other. Mani Monday Thailand diamonds (2557) is understanding that there is a communication tool?
