Questions:
1. What is broadband?
Broadband is the term used for any kind of fast Internet access. Broadband is designed to give a business or residential user instant Internet access 24 hours a day.

2. What units are used to measure bandwidth?
The speed of a modem is measured by the number of bits of data it can transmit per second, expressed as kilobits per second (Kbps). The larger the Kbps transferred, the faster you will download pages or other material such as music or email from the Internet.
The standard prefixes of size/speed are used to indicate the number of bits. A kilobit is about 1000 bits, so a 256Kbps speed will transfer 256 000 bits of information per second. A megabit is about 1 million bits and a gigabit is about a billion bits.

3. How much faster is broadband than dial up?
Broadband is at least five times faster than dial-up. It enables you to access services and opportunities through the Internet, such as VOIP (Voice over Internet Protocol), streaming media and online gaming, which are simply not practical on a dial-up connection.
Broadband is 'always-on' which means as long as your computer is switched on, you can be connected to the Internet.

4. What are the speeds that broadband operates at compared to dial up?
10-20 times faster than your existing dial-up modem. A typical dial-up modem operates at either 28.8 kbit/s or 56 kbit/s. A broadband connection operates at between 256 kbit/s and 10 Mbit/s, depending on the service you have selected. To give you an idea of the difference that this speed can make, a 3.5 minute MP3 music file takes about 18 minutes to download using a 28.8 kbit/s dial-up modem but only about 21 seconds on a 1.5 Mbit/s broadband link. An e-mail containing a family photo takes about 55 seconds at 28.8 kbit/s but only about three seconds on a 512 kbit/s link.

5. What are some of the advantages of using a broadband connection to download something like a video compared to dial up?
Broadband can allow you to transfer large files of text or graphics at high speeds give you instant access to webpages, even those with large amounts of graphics that are typically very slow to download on a dial-up connection; allow employees to telecommute, operating from their home or elsewhere with the same response speeds and level of security as if they were in their office; link several computers to the Internet through the same connection; make videoconferencing faster, smoother and more practical; save money by allowing a business to rationalise and centralise its servers.
