CONNECTION METHODS
There are three methods for connection to the internet. Availability of each may depend on location.
1. WIRELESS Connects without using wires. Not fixed to a stationary computer. Can be used wherever wireless internet is available. Needs to have wireless internet available. Can be less secure than wired.
Internet WIRELESS ACCESS POINT
2. BROADBAND A wired connection through a broadband supplier. Better reception and faster than dial-up. Wired so has to be used on a stationary computer.

3. DIAL-UP A wired connection using a modem and telephone lines. Can use existing telephone lines, giving connection where broadband is not available. Older technology can give poor reception. Conversion between analogue signals can cause errors. Usually slower than other methods.

BANDWIDTH Bandwidth is how the speed of section of the internet is measured. It describes how much capacity (space) there is to carry data. Bandwidth is measured in bits per second the number of bits of data that can be transmitted is one second. High bandwidth means more information can be moved during that time, therefore giving faster internet connection and a higher transmission rate.
Model Question 1 Describe the effect low bandwidth would have on the running of a website and why this might be. (2 marks)
Model Answer 1 Low bandwidth would make the website run slowly. This is because less data can move through the cables (less bits per second), therefore the data is moving more slowly.
Model Question 2 Choose the best internet connection for each of these people from the options below.
