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:
1. the size of computer files
2. the speed of transferring those files over the Internet
3. 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:
1. Definitions of terms which express the size of computer files and/or computer data.
2. Definitions of terms which describe the speed at which various Internet connections
will transmit data.
3. 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.
