Data Measurement Chart
Starting with the Data Measurement Chart, you can see the difference between
things like a "Kilobyte" and a "Megabyte" and other computer
memory terms. For example, an average web page might be about 16KB in size. To
understand just how big that is, you can consult the first chart, the Data
Measurement Chart.
The charts below will give you a clear understanding of:
- the size of computer files
- the speed of transferring those files over the Internet
- and how fast those transfers are relative to the type of connection one
has to the Internet. Remember, speed is everything.
There are three basic, simple things you need to know first:
- Definitions of terms which express the size of computer files and/or
computer data.
- Definitions of terms which describe the speed at which various Internet
connections will transmit data.
- The difference between the speed of those Internet connections.
Next, you want to know definitions of terms which describe the speed at which
various Internet connections will transmit data. The Data Transfer Rate Chart
explains this and will tell you the difference between a "Kbps"
connection or a "Gbps" connection.
The final chart, the Connection Speed Chart, shows the difference between
having a 28.8K modem or a DSL connection and so forth.
Below the three charts begins the glossary definitions of terms used in
video, film and Internet technology.
