<p class="intro">Make sure you get the disk space and the traffic volume you
need.</p>
<hr />
<h2>How Much Disk Space?</h2>
<p>A small or medium web site will need between 10 and 100MB of disk space.</p>
<p>If you look at the size of HTML pages, you will see that the average size is
very small. Maybe even smaller than 1KB. But if you look at the size of the
images (button, gif, banner, jpg) used inside the pages, you will often find
images many times larger than the page itself.</p>
<p>Expect each HTML page to take up between 5 and 50KB of disk space on your web
server, depending on the use of images or other space consuming elements. </p>
<p>If you plan to use lots of images or graphic elements (not to mention sound
files or movies), you might be needing much more disk space.</p>
<p>Make sure that you know your needs before you start looking for your web
host.</p>
<hr />
<h2>Monthly Traffic</h2>
<p>A small or medium web site will consume between 1GB and 5GB of data transfer
per month.</p>
<p>You can calculate this by multiplying your average page size with the number
of expected page views per month. If your average page size is 30KB and you
expect 50,000 page views per month, you will need 0.03MB x 50,000 = 1.5GB.</p>
<p>Larger, commercial sites often consume more than 100GB of monthly traffic.</p>
<p>Before you sign a contract with a host provider, make sure to check this:</p>
<ul>
<li>What are the restrictions on monthly transfer</li>
<li>Will your site be closed if you exceed the volume</li>
<li>Will you be billed a fortune if you exceed the volume</li>
<li>Will my future need be covered</li>
<li>Is upgrading a simple task</li>
</ul>
<hr />
<h2>Connection Speed</h2>
<p>Visitors to your web site will often connect via a modem, but your host
provider should have a much faster connection.</p>
<p>In the early days of the Internet a T1 connection was considered a fast
connection. Today connection speeds are much faster. </p>
<p>1 byte equals to 8 bits (and that's the number of bits used to transport one
character). Low speed communication modems can transport
from about 14 000 to 56 000 bits per second (14 to 56 kilobits per second). That
is somewhere between 2000 and 7000 characters per second, or about 1 to 5 pages
of written text.</p>
<p>One kilobit (Kb) is 1024 bits. One megabit (Mb) is 1024 kilobits. One gigabit
(Gb) is 1024 megabits.</p>
<p>These are connection speeds used on the Internet today:</p>

<p>Before you sign up a contract with any hosting provider, surf some other web
sites on their servers, and try to get a good feeling about their network speed.
Also compare the other sites against yours, to see if it looks like you have the
same needs. Contacting some of the other customers is also a valuable option.</p>
