Broadband technology is seen as the key to the new digital economy. In this rapidly changing world, media and technology information can be sent via phone calls and downloads like music, graphics, business information or films. The simpler the information, the smaller the package and the narrower the bandwidth needed to deliver it.
Broadband is used for high speed Internet connections at a fixed monthly rate. It turns an existing telephone line into a high speed digital line capable of carrying data up to 40 times conventional modem speeds. Any download is available at the click of a mouse—there is no dial-up as there is with standard Internet Service Providers. For home owners and families there are many advantages. One of the most important is simultaneous(同时的)access to both telephone lines and the Internet. No queues and no delay. For businesses, broadband can improve customer relations and provide direct access to corporate e-mails and databases. Entire operations can go online. [br] Compared with the modem speed the broadband technology can transmit data______.
