Size Matters! Or Does It? On Space & Bandwidth
A Bit of This, A Byte of That: Crunching the Numbers
If someone offers you the world, decline politely and run away.
It is not theirs to give.
If someone offers you unlimited bandwidth, storage space,
speed, or traffic, do the same.
However boring or mundane a sensible, reasonable offer may be,
take it over the hyped-up one any day of the week.
In the end, it is not the superlatives and hype that matter,
rather common sense; brains ultimately triumph over brawn,
and content is indeed king. It is not shear size or space that
it going to keep clients coming back to your website,
but what you do in that space, what you have to offer them, be it goods,
services, or useful information.
However, because information on computers is stored in
binary numbers - 0's and 1's - as most of us now know, we must be
aware of the basics of brawn to some extent. For computers are not brains.
They are dry and finite machines with only so much storage capacity,
as most of us now know also, having found out the hard way!
Too much is never enough...
So let's start with the basics of brawn, however boring,
just so we are sure of the common terms we are about to discuss -
it is a quick, relatively painless lesson; and then, we'll know.
A "bit" is the smallest unit of digital information,
and consists of ones and zeros; this often translates to
something being "on" or "off" - like a light or a pregnancy,
there really is no in-between state, as much as we'd like there to be one.
True or false makes a computer happy.
1,024 bytes equal 1 "kilobyte" (Kb). Why? Because the math is clean.
We are working in a binary world here. 1,024 / 8 = 128; 128 / 8 = 16;
and 16 / 8 = 2. The data cubes can be neatly packed and shipped this way.
1,024 kilobytes (Kb) are equal to 1 "megabyte" (MB or "Meg" as
we like to call her.) As you can see, you get more bang for
your buck in cyberspace, kind of like a "Baker's Kilo" where
you get 2 dozen extra every time!
1,024 megabytes are equal to 1 "gigabyte" (Gb or "Gig", something
people used to dance about, but something that is now quite common).
No one blinks at 10 Gig hard drives any more, do they?
But what would all that information look like in a pile in
the middle of your room? Would it even fit in your room? No one's
really sure, but we'll come back to this later, anyway.
1,024 gigabytes are equal to 1 "terrabyte." Now "terra" is big!
Almost incognito! Like a Terra-dactyl! Sorry about that. The fact is
that this is as far and as big as we need to go - no web hosts offer
terrabytes of anything - bandwidth, space, service or what-have-you.
As usual, some people out there like to bend the rules, and use the
old Kilo = only 1,000 equation; it's best to check with the party in
question to see what rules they are playing by.
Of course, it sounds faster if you're sending less data per second; so,
in terms of speed, you'll often be getting this, in these terms:
Bps = bits per second
Kbps = kilobits per second = 1000 bits per second
Mbps = Million bits per second = 1,000,000 bits per second
Gbps = Gigabits per second = 1,000,000,000 (one billion) bits per second
Tbps = Terabits per second = 1,000,000,000,000 (one trillion) bits per second

What do You Really Need? How Much is Enough?
We are so used to wanting to get as much as we can for our money
that we sometimes do not realize that we can never use it all.
If that's the case, why pay for it? Answer: because you don't know
how much is enough and how much is too much!
If I'll never be able to use it, why are they offering me so much?
Answer: because (they know) you'll never be able to use it!
If MegaHost offers you a Gig of bandwidth and UltraHost offers you 500 Megs at the same price. Who you gonna call?
Answer: it should depend
on a number of other factors. Like their Customer Service? Are the
lights on but nobody seems to be home? Nowadays, this seems to be
the exception rather than the rule!
Action: Email them!
Ask them anything, and see if someone - a human! - gets back to
you with a sensible answer.
The fact is that more
and more web hosts have the equipment required, but not the personnel.
Check out their complete packages, what all they are offering you,
what all you need, and then compare prices. If a few dollars a month
really matters to you, perhaps you need to reconsider your business
plan.
So how much space do
I really need, then? Answer: it depends. Work it out.
Calculate your page
sizes and add them up. If you have too many pages to be bothered
doing this, "guesstimate" your average page size first.
The average web page
on HostSearch, for example, uses about 50 kilobytes of space, some
less, some a little more, and this includes a fair number of graphic
images, which we are sure to make as small as possible. This means
that we could fit about 20 HostSearch pages into a single megabyte
of space. If you were to purchase 100 megabytes of space from a
web host, then you could fit the equivalent of 2,000 HostSearch
pages into your web site!
Many sites are small
and modest - you are not Microsoft after all! - and do not need
more than 10 or 20 megabytes of space max. Still, some websites
may require more, for the following reasons: graphics and dynamic
content, such as multimedia files. Always ask yourself, "Do I need
all these graphics or multimedia files?" "How can I make my pages
smaller?" "Do I need all these tables?" "Should I split this page
into a number of smaller pages?"
The average graphic
uses between 5 Kb and 50 Kb of space alone. Always check your graphic
sizes and use a good graphics program to make them as small as possible
- "Save for Web" is a great new feature of many graphics programs.
If a web site has many different graphics, then it will certainly
need more space.
Also, some web sites
have message forums. These forums can generate web pages very quickly
and obviously require more space. Another reason you may need more
web space is if you are offering software or other products or files
for your visitors to download. You would then need to store these
products within your allotted web space and again, all these items
will take more space.
So, figure out how
much space you are currently using and then approximate how much
you think your site may grow from here. If you do not yet have your
web site finished, or are not experienced in this area, or hate
anything to do with numbers, it may be somewhat more difficult to
decide how much space you will need.
In this case, HostSearch
recommends that you start with around 20 megabytes of web space.
This should give you more then enough room to move, and you will
not have to pay too much for this amount of space.
If your site is obviously
very small, mostly text, and free of graphics, you can probably
host your site on 2 MB of space, which is about 200 pages of text.
For most average sites, 50 to 100 MB is an awful lot of space. Cyber-malls
and big Net Communities may require approximately 200 to 400 MBs
of space, but do you? In general, 1 MB equals about 100 pages of
text.
If your web site does
eventually use up the space you bought, fear not: you should easily
be able to purchase more space from your current host. Thus, it
is important when searching for a web host to make sure you find
one that makes it easy to upgrade and does not charge extra fees
for doing so, outside of the cost of the upgraded package of course.

What about Bandwidth and Data Transfer?
The other big buzzword
for web hosting these days is "bandwidth," not to be confused with
"data transfer." All kinds of numbers and loose interpretations
are bandied about. So what is it, anyway, and how much of this do
I need?
If you have a heavily
trafficked site, you will certainly require a large amount of bandwidth
and data transfer each month. You should also be aware of the differences
between bandwidth and data transfer, as some hosts will blur these
into one feature for the unknowing.
Bandwidth and data
transfer are in fact different! Look at it this way. Imagine bandwidth
as a water pipe. The bigger the pipe, the more water you can potentially
get through it. Whether you're gonna need or use all that water
is another issue!
Data transfer is the
amount of water that passes through your pipe.
For example, this is
one example of bandwidth --> 1.5Mbps (T1);
This is an example data transfer limit --> 1GB per account.
I know that some web
hosts used the word "bandwidth" to refer to data transfer. That
confuses people (including me before!).
To spell it out a little
more clearly, data transfer is the amount of data transmitted or
received through a unit of time. In web hosting, data transfer is
consumed when visitors make requests for files on your web site
and download them to their personal computers. When you add up the
total of all files downloaded from your site in a particular month,
your total should be lower than the amount allotted within your
hosting plan. If it is not, your file sizes may be too large or
you may be generating a lot of hits - in which case you may need
to upgrade to a larger hosting plan or to a dedicated hosting server.
(Please see our article on Dedicated Servers.)
When you load a HostSearch
web page, for example (recalling the average HostSearch page is
50 Kb), you are downloading 50 Kb of data. How this adds up is the
same as we noted above when discussing web space. A 50 Kb web page
can be loaded 20 times before using a single megabyte.
Be sure to remember
that each file within a page is calculated also. So if you were
to have a 20 Kb web page (HTML file) that also included three 10
Kb images, then every time the page was visited, 50 kb of data transfer
would be used: 20 kilobytes for the page and 30 kilobytes for the
images. Very straightforward indeed.
If designed correctly,
a web site can be very successful and receive many visitors, 24
hours a day, 7 days a week, and still not come close to their data
transfer limit. In fact, some of the most successful and popular
pages on the Web are very small, Yahoo!'s homepage for example.
Most people can do without the bells and whistles, and the waiting
time involved for over-designed and over-stuffed pages.
Remember that your
success is dependent on how you develop, promote, care for, and
remain dedicated to the task at hand - your site. If you care about
the success of your web site, then you will care enough to educate
yourself about what it is your web site really needs. This includes
finding a host that will meet those needs efficiently and honestly.
With data transfer,
it is equally simple to guesstimate how much you will need if you
have an existing web site: by checking your current usage and evaluating
it from there. Multiply the size of your biggest page with all the
graphics by the number of impressions your site is getting, or will
get. For example: 50 Kb X 10,000 = 500,000 Kb; in other words you'll
need 500 Megs if your site generates 10,000 page views monthly.
Never settle for less than 1 Gigabyte.
For the first timer,
determining bandwidth and data transfer needs may be a bit more
difficult. HostSearch's recommendation: 2 gigabytes of data transfer
per month is usually more than enough to start out and big enough
to allow your site room to develop and grow. This is included, at
no extra charge, with the majority of packages most web hosts offer.
If the host is not offering a minimum of 2 gigabytes, you may want
to shop around a bit more and find one who does.
Again, you will want
to make sure the host you choose allows room for growth in case
your site does end up requiring more than anticipated. Remember,
just as with space, if a site contains an enormous amount of images,
message forums, or other products for download, your bandwidth and
data transfer needs will be higher.
Many web hosting companies
will promise you "unlimited" traffic, but you must check carefully
to see what they mean by "unlimited". Hosts that are currently promising
you unlimited bandwidth or data transfer are either not being honest
with you, have many hidden restrictions they are hoping you will
not notice, or simply are not educated themselves, and are possibly
risking their entire business on the hope that their clients will
not get that much traffic. Once you exceed a certain quota, they
may start charging you. Read the fine print. Any webhost that offers
unlimited anything will usually have a little asterisk and when
you follow that asterisk, you will find that there is indeed a limit.
Caveat emptor (let
the buyer beware): if a web host claims to offer you a certain amount
of hits, transfers, or page views, they are either showing a lack
of education with respect to their business, or they are assuming
that you, their potential client, are not educated enough to know
what these terms mean. A hit means someone has downloaded a file
from your web site; a page view means someone has visited your web
page; and a transfer is the same as a hit.
The host is actually
referring to data transfer when they make this offer. The problem
with the offer is that there is no way for the host to know what
size each of your files will be. Therefore, there is no way for
them to predict how many hits, transfers, or page views they will
be able to offer you. We recommend that you either avoid a host
making these claims or at least question them to confirm exactly
how it is they calculate a hit, a transfer, or a page view in terms
of data transfer.
Finally, any web site
that needs more then 15 gigabytes of data transfer per month should
be on what is called a "dedicated" server. Dedicated servers are
servers that host only your site; they do not share the resources
with other sites. These are more expensive than "shared" or "community"
hosting, as you would expect, but if you care about your site's
success and are using more then 15 gigabytes of data transfer, then
dedicated is the way for you to go.
And remember: when
you search for a company on HostSearch to meet your needs, your
search results will contain a link to much of this information about
different web hosts, so you can compare and make an informed decision
as to what is best for you.
