Bandwidth refers to the amount of data that can be transferred over an internet connection in a given period of time, typically measured in kilobytes or megabytes per second. The more bandwidth available, the faster multimedia products containing various types of media like video, audio and images can be downloaded and interacted with. Limitations of small bandwidth include slow download speeds for multimedia content and potential throttling of downloads to prevent overuse of the connection.

3. What is Bandwidth?
Think of where you have heard of it before…

4. Understand meaning of bandwidth
Bandwidth Be able to describe limitations
 This is a measure of how much data can be used
within a second e.g. Kilobytes per second or
Megabytes per second.
 Sometimes people want to look at lots of data at
once, especially with interactive multimedia
products. This might include text, videos, images,
animation and sound.
 Bandwidth is often restricted to only allow so much
data to filter though at a time and this is when you
might find that some products run slowly.

Bandwidth Be able to describe limitations
 Download times for Virgin Media:
30mb 60mb 100mb
Album 18 sec 9 sec 6 sec
TV Show 102 sec 54 sec 30 sec
Movie 5 mins 2.5 mins 1.5 mins
HD Movie 20 mins 10 mins 6 mins
 The larger the connection size the faster the
download will occur.
 Bandwidth can be throttled to prevent further #bandwidth #limit
downloads from taking place.

8. Key Words
 Bandwidth  The measure of how much data is allowed
along a connection every second
 Limit  The point beyond which something may not go
any further
 Multimedia  A product that combines various types of
media such as images, audio, video etc.
