    　　Over the past 10 years, technologies that have combined computers with telephone have developed．Technologies such as PC fax programs and LAN fax servers(局域网传真服务器)have been used to improve fax communications．The latest computer-based technologies are new mechanisms(机制)which use IP(Internet Protocol, 因特网协议)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 starts 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(PSTN，公共电话交换网)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：store-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 enabled 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, anything with an internet fax address．

    　　A mobile phone（手机）is in fact a small radio. A radio sends a person's voice over a long way to another radio. A voice that is sent by radio is called a signal（信号）. A radio signal travels very quickly.

    　　Only a few years ago, mobile phones were very large. They needed large batteries（电池）. They had to be powerful（功率高）to send their signal to faraway places. This was because most cities had only one antenna tower（中继站）for mobile phones.

    　　Today's mobile phones are small and easy to use. Now most cities have a lot of antenna towers, not just one. This means that each mobile phone doesn't have to send its signal far away, so they don't need to be so powerful. Mobile phones today use small batteries. A large city, where lots of mobile phones are used, can have hundreds of towers.

    　　Do you know what use a mobile phone has? Yes, you can use it to do a lot of things.

    　　Call your friends and family from almost anywhere.

    　　Call the police immediately if there is an accident in the street.

    　　Send or receive e-mail.

    　　Get information from the Internet.

    　　Send and receive messages.

    　　Sending short written messages is a popular way to use your mobile phone. Many people use short forms of words, so the messages are quick to write and read. Can you guess what these messages mean? Try reading them out. What do you hear?

    　　RUOK?

    　　CUL8R!
