One GB is 1024 Megabyte or 1073741824 bytes. You can do the following with 1 GB download limit :

1. An average web page is about 50 kilobytes in size - so you could download around 20,000 web pages for 1 gigabyte.

2. An hour of surfing the web would be around 10 megabytes (200 pages) so you could surf non-stop for about 100 hours for 1 gigabyte.

3. An hour of streamed radio would use about 15-20 megabytes.

4. An hour of streamed video uses around 100-150 megabytes.

5. Playing an online game typically uses about 10-15 megabytes per hour.

6. Emails are very small - so 100 emails would be just 1 megabyte - or 100,000 emails for 1 gigabyte! (of course the attachments count extra)

7. A super-high resolution (5-6 megapixel) digital camera JPEG picture or typical MP3 music file is about 2-3 megabytes so you could download 350-500 of these images/music files for 1 gigabyte. Very few users would actually exceed the download limits set.

A firewall is a system designed to prevent unauthorized access to or from a private computer/network. It is highly recommended that all Internet users (even using standard dialup access ) should have a firewall to protect their computer/network. As ADSL broadband service are Always on it is even more important. Many free firewall softwares like ZoneAlarm, Sygate Personal Firewall etc are available on the Web for download.

In broadband connection it is different from dial up connection. Here frequency does not matter as it is always on connection. What matters is the size of the pages you visit. If you visit sites which are having small graphics and more text then you are downloading very small amount of data. But if you are visitIng sites with large graphics or streaming videos then you are downloading higher amount of data.
