hmm, what's the difference between space and bandwidth? What does each does? Because I'm buying a hosting plan with 300MB Space and 8GB Bandwidth and plan to host people and stuffs. Would it be enough or too much? Because i don't know the difference between the two. Please help!

"space" is the amount of space you get on the server's hard drive for your files. bandwidth is a measure of the data transferred between the server and the visitors computers.

the quantity of each you need really depends on your site. add up the sizes of all your files, and that's the amount of space you'll need. multiply that by how many visitors will be viewing all those files and that's how much bandwidth you'll need. (so if 100 people view your 15 KB home page, that will use 1500 KB of bandwidth- plus all the other files that those people view)
