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 exciting telephone line into a high speed digital line capable of carrying data up to 40 times conventional modern speeds. Any download is available at the click of a mouse-there is no dial-up as there is with standard Interact 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. N A. further B. critical C. costly D. global [单项选择]上表面紧实度高,下表面紧实度低的机器造型方法是()

A massive flood caused by heavy monsoon rains has devastated large parts of Bangladesh.

Power lines, roads and other infrastructure have sustained major damage as well. Hundreds of people have been killed in the initial flood, and there is concern that thousands more will die due to water-borne diseases and other hygiene-related health problems.
