What do I need to know about bandwidth?

Bandwidth
The amount of bandwidth your web site requires will depend on the amount of traffic your web site gets. Obviously, the more traffic your web site has (or expects to have) the more bandwidth you will need. Most small and medium sized web sites will require about 30 to 40 megabytes of bandwidth. Most web hosting companies have basic plans starting at about 10 gigabytes (more than enough for most web sites).
FYI: 1000 megabytes = 1 gigabyte.
