PhilipE: Ok, strap on your propeller beanie, here comes some serious geek stuff..
There are two numbers associated with all hosting accounts. How much storage space you get for your web pages, photos, etc. i.e. content and how much traffic your site is allowed before being charged extra.
In the example of the Fatcow folks, the 1 GB refers to the storage space you get to put all your stuff in such as your web pages, videos, photos, etc. (Site features such as bulletin boards or other extras do not count against this limit). So it's like the trunk of your car, it's where you put your stuff that makes up the web site.
The 30GB refers to how much traffic you are allowed each month. Traffic (or bandwidth) is what happens when someone comes to your site. When someone types in your site URL (e.g. Multimedia File Viewing and Clickable Links are available for Registered Members only!! You need to
or
) the machines at the other end called servers "serve" up the index or home page of your site. That means they have to transmit data through the net into your computer. That's traffic! And if the "size" of your page is 100kb then that 100kb is subtracted from the 30GB of bandwidth or traffic you are allowed. Every time someone goes to your site or a differnt page on your site, etc. i.e. every time the servers has to "serve" up a new page, that bandwidth is subtracted from the 30GB total allowed per month. What happens if you use or have traffic in excess of 30GB? They charge you extra.
Virtually all webhosting accounts work this way. If you are going to run a larger commercial venture then you can and should use a different type of web host provider (think big bucks) but for those of us just doing personal sites or sites for organizations (like my nephews baseball team or the neighborhood association) then hosting like Fatcow or GoDaddy (i.e. shared hosting) is just fine.
As for account sizes 1GB of storage is a lot and 30GB of bandwith is a lot! My nephews baseball site has lots of graphics, pictures from practices, and some video and I've only used about 15MB so far. As I add entire games of video, I might get close to filling it and using up the bandwidth but I doubt it will ever be a squeeze.
Hope that helped. If not, let me know and I'll take another stab at it. If you need more detailed help, send me PM and I'll see what I can do. (we are getting a bit off subject here. )
Cheers.
