BROADBAND.

1) What is broadband?
A connection allowing large amounts of data to be processed very quickly, and can split the available bandwidth into multiple channels. Basically a term which is used to describe high bandwidth which is greater than 256 bps. This is measured in kilobits, which is a unit of computer memory or data equal to minimum of 1,024 (210) bits.
2) What units are used to measure bandwidth?
The units used to measure bandwith is bits per second, although you can also use bytes yet this is not preferred as much. The units of measurement you are using depends on the computer network bandwidth. All together, the units are, bits, kilobits, megabits, megabytes, megabytes per second and megabits per second.
3) How much faster is broadband then dial up?

Dial up is the use of a telephone in order to establish a connection, it persists of 56 kbps. On the other hand broadband consists of at a minimum of 256 bps. Dial up may take a long amount of time, when being used for internet, such as if downloading a file, it may take hours or maybe even a day. Although broadband, may take up to minutes or even seconds depending on the rate the bits are processing at. The difference between both broadband and dial up is of 200bps of difference. :)
4) What are the speeds that broadband operates at compared to dial up?
The speeds that broadband operates at is at a minimum of 256 bps, although dial up's average speed is 56 kbps. Basically, broadband is seen as better and faster than dial up and is highly preffered.
5) What are some of the advantages of using a broadband connection to download something like a video compared to dial up? A broadband connection is ten times faster than a standard dial up connection, you pay for what you get. Also if you have dial up, you always have an engaged phone line which makes a lot of noise, but using broadband, you can use your phone and your internet at the same time with no interrupting noises. In majority of cases, broadband can be seen as cheaper than paying for your monthly line rental and dial up subscription. Broadband is the alternative for everyone! :)
