Over the past 10 years， technologies that have combined computers with telephone have developed. Technologies such as PC fax programs and LAN Fax servers （局域網(wǎng)傳真服務(wù)器） have been used to improve fax communications. The latest computer-based technologies are new mechanisms （機(jī)制） which use IP to send faxes， that is， IP fax.

Traditional fax has a fairly simple usage model. First， the user inserts a document into the fax machine， enters the destination fax number and presses the start button on the machine. The sending machine dials the receiving fax machine. If it connects， the sending machine scans the documents and sends it over the public switched telephone network （公共電話交換網(wǎng)） to the receiving machine. At the same time， the receiving machine receives the document and then prints it.

In IP fax system there are two basic transmission modes： sore-and-forward mode and real-time mode. Store-and-forward mode has been widely used. In this mode， the entire document is sent to a network-based server that stores it and then sends it to the destination. Real-time IP faxing is similar to traditional fax. Real-time mode allows two fax machines to directly communicate through some standard.

IP fax enables a fax document to be sent from one person to another. A fax machine or a computer can be used to send or receive the fax. IP fax also allows e-mail to be used to receive faxes. This would enable users to receive faxes anywhere， anytime with an Internet fax address.

United Nations officials warn that many animals important to agriculture are disappearing forever. The UN Environment Program and Food and Agriculture Organization released a report with the new findings. The findings are based on the information collected in one hundred and seventy nations during the past ten years.

FAO officials say the world has lost about one thousand kinds of farm animals in the past one hundred years. The officials say many other breeds are still in danger. They warn that one-third of them are at risk of disappearing.

About two thousand million people depend at least partly on farm animals to earn money. That is one-third of the worlds population. They warn that meat， milk and egg production will need to increase by more than twice during the next twenty years.

FAO officials have gathered information about more than four thousand kinds of birds and animals. Seven hundred and forty of those breeds on longer exist. More than one thousand three hundred others are said to be endangered or at high risk of extinction.

Many of them are very important farm animals. For example， in Madagascar， Renitelo cattle have almost disappeared. In the Philippines， the Banana chicken is now rare. Fewer than one thousand of the birds remain. In Mexico， the Chiapas sheep are at risk of disappearing.

The report warns that more than two thousand other breeds could disappear within the next twenty years unless action is taken. It says the greatest threat is the export of animals from industrial nations to developing countries. It says this can lead to replacement of some native animals.

The report says animals from industrial nations are often considered more productive in developing countries. However， it says these animals are best for the environment of the areas they come from. It says they may have a difficult time surviving under extreme conditions.

The FAO says having different breeds of animals is a way to protect against loss of animals from severe weather conditions or the spread of disease. The UN agency is starting a five-year project to help countries better understand the issue.
