Bandwidth Computing

1).  What is Broad band?

Is a high data rate connection to the internet.

Def.com :  Of or using signals over a wide range of frequencies in high-capacity telecommunications, esp. as used for access to the Internet.

2). What units are used to measure bandwidth?

Bit rate - bits or bytes per second

3).How much faster is broadband than dial up?

The most you can get is around 56Kbps for dial up where as compared with broadband ,it allows a large amount of data to travel through a medium at the same time. In my opinion from extensive research broadbrand is much faster than dial up

4). What are the speed that broadband operates on compared with dial up?

Read the paragraph below:

Think of your connection to the internet as a tunnel that links your computer to the internet. A regular phone line can allow only a small amount of data to pass through at a time. In comparison, a broadband is a wider (or broader) tunnel, allowing a greater amount of information to pass through your connection at one time. The width of this tunnel is called "bandwidth." The more bandwidth you have, the faster you can move data.


6. Create an image in paint that illustrates how a high bandwidth connection can move more data compared to a dial up connection at a given time.
 Have a look at the Australian Bureau of statistics website link below. It shows all of the internet usage in the last 3 years. Answer the following:


A] How many people subscribed to the internet in 2007? How many of these were for business use? How many for home use?

Alot of people still used dial up most if them in 2007 have converted to DSL with about less then 3 quaters using cable and mobile or fixed wire.


Have a look at the site below. It tests the speed of your internet.


1. What is the speed of the connection from your computer to the Sydney location on the map?

0.02 Very slow.
