Web Hosting - Bandwidth and Server Load, What's That?
Two key performance metrics will impact every web site owner sooner or later: bandwidth and server load.
Bandwidth is the amount of network capacity available, and the term actually covers two different aspects. 'Bandwidth' can mean the measure of network capacity for web traffic back and forth at a given time. Or, it sometimes is used to mean the amount that is allowed for some interval, such as one month. Both are important.
As files are transferred, emails sent and received, and web pages accessed, network bandwidth is being used. If you want to send water through a pipe, you have to have a pipe. Those pipes can vary in size and the amount of water going through them at any time can also vary.
Total monthly bandwidth is a cap that hosting companies place on sites in order to share fairly a limited resource. Companies monitor sites in order to keep one site from accidentally or deliberately consuming all the network capacity. Similar considerations apply to instantaneous bandwidth, though companies usually have such large network 'pipes' that it's much less common for heavy use by one user to be a problem.
Server load is a more generic concept.
It often refers, in more technical discussions, solely to CPU utilization. The CPU (central processing unit) is the component in a computer that processes instructions from programs, ordering memory to be used a certain way, moving files from one place to the next and more.
Every function you perform consumes some CPU and its role is so central (hence the name) that it has come to be used as a synonym for the computer itself. People point to their case and say 'That is the CPU'. But, the computer actually has memory, disk drive(s) and several other features required in order to do its job.
Server load refers, in more general circumstances, to the amount of use of each of those other components in total.
Disk drives can be busy fetching files which they do in pieces, which are then assembled in memory and presented on the monitor, all controlled by instructions managed by the CPU.
Memory capacity is limited. It's often the case that not all programs can use as much as they need at the same time. Special operating system routines control who gets how much, when and for how long, sharing the total 'pool' among competing processes.
So, how 'loaded' the server is at any given time or over time is a matter of how heavily used any one, or all, of these components are.
Why should you care?
Because every web site owner will want to understand why a server becomes slow or unresponsive, and be able to optimize their use of it.
When you share a server with other sites, which is extremely common, the traffic other sites receive creates load on the server that can affect your site. There's a limited amount you can do to influence that situation. But if you're aware of it, you can request the company move you to a less heavily loaded server. Or, if the other site (which you generally have no visibility to) is misbehaving, it's possible to get them moved or banned.
But when you have a dedicated server, you have much more control over load issues. You can optimize your own site's HTML pages and programs, tune a database and carry out other activities that maximize throughput. Your users will see that as quicker page accesses and a more enjoyable user experience.
Yes, There Really is a Freebie Santa Claus If you are a cynic when it comes to offers of free stuff, you are not alone. Everyone has had notions like “there is no such thing as a free lunch” and “if it sounds too good to be true then it probably is” drilled into their heads, and for good reason – these things often hold water. On the flip side, there ARE actually lots of places you can score some decent free stuff, if you know where to look and are willing to devote some time to hunting them down. The key to getting the best free stuff with the least amount of hassle is to stick with that healthy cynicism but to also dipping your toe in the freebie pool little by little. But why would anyone give stuff away for free? It is certainly an obvious question, but if you stop to consider it for a moment, you can see that companies actually have a lot of motivation to give away free stuff. After all, if they give you something for free, you are bound to have a little soft spot for their company, and when you are ready to part with some cash, their product may near the top of your list. Also, by giving away free things, companies can convince people to try new products. You might not want to try a new kind of shampoo if you have to pay for it, but you’d certainly be willing to give a free sample a try. You may end up loving it and switching to that shampoo for good, turning you into a paying customer. Another reason a company might give you free stuff is to complete market research. This is where getting free things can get a little complicated for some people because the products may not cost you money, but the offer may cost you a little time. A company might ask you to take a survey of your buying habits before they give you a free offer, or they may ask you to provide feedback on a regular basis as you try their product for free. Some people balk at the time commitment required here, but for other people, filling out some paperwork is a small price to pay for some free stuff. Of course, to convert you into a customer or to communicate with you about market research, a company will have to contact you, which is complicated area number two for freebie lovers. You will almost always be forced to hand over your email address in order to cash in on a free offer, and that is a recipe for opening your inbox up to a barrage of spam (many companies sell your email address to offset the costs of their free promotions, which means the number of people soliciting you can go through the roof very quickly). If you want to avoid this downside of freebie hunting, set up a special email address specifically for your freebie deals. That way all of your spam goes to this one address and your regular email you use with family and friends remains free and clear. One final note of caution about free stuff online: a lot of scammers have hit on the idea of using pretend freebie offers to solicit personal information about people or to convince people to send them money. Don’t send money, even for postage, to a company you don’t know and never, ever give out personal information online. No reputable company is going to ask for your social security number or bank account details for a freebie offer, so don’t hand them out to anyone. When in doubt, skip it and move to the next freebie. Software copyright buy For Software Copyright Buy Locally To gain permission to use software copyright, buy the software. This sounds like such a simple solution and yet I know this isn't always as easy as it seems. Software is expensive, largely due to misuse and abuses of the past and the average consumer can't always afford to buy the software package and product he or she needs for business or pleasure. It is important when setting priorities for software purchases that you don't limit all your purchases to pleasurable pursuits. When making copyright software buy, be sure that you are getting the best possible product for your money. I've seen so many people spend foolishly for one product because it is the most common product on the market when another less expensive product would have been completely adequate at far less than half the price. Most people never use the bells and whistles they pay for when purchasing software. The best way to be sure that you are getting the best copyright software buy you can possibly get is to make a list of things you need your software to do, the things you'd like it to, and find all the software on the market that does those things. Find the one with the lowest cost and the most necessary features and let that be the software you decide to purchase. Don't make these decisions on the spur of the moment as you will almost always cost yourself more money in the long run. Another way to insure that you are getting a great copyright software buy is by comparing prices at local and online stores before making the purchase. You might be surprised by where you will find the lowest price (also keep in mind shipping costs when purchasing online they do swing the vote sometimes). Comparative pricing can save you hundreds of dollars in the course of a year on personal software and quite literally thousands of dollars each year on professional software. Be sure to make those decisions wisely as money spent poorly is money that could have been spent elsewhere. You should always remember when comparing prices and searching for the deal of the century when it comes to copyright software buy from a reputable source. This shouldn't have to be said but it really must be said. You would be amazed at how many people have received pirated software from purchases they've made online. This is an especially bad things for business deals in which the software was needed rather than personal software that was merely wanted and looked forward to. In business you could very well loose your investment in the pirated software as well valuable time getting the copyright software buy you actually needed in the first place. While the costs of doing business locally are often more expensive than it can be online I do recommend that for some purchases, particularly copyright software buy locally even if it is a little more costly. It's nice to know that there's a person on the other side if something goes wrong and that they want your business and want people in the community to respect their business. In other words local businesses are much more likely to give the personal touch and protect their reputations by doing the right thing. There are many other reasons that buying locally is good for you and your business buying needs. Buying locally for your business will establish your business locally (this is especially good if you don't have a huge presence or massive storefront from which to advertise). It also helps you make important business contacts in order to help your local business grow. For your copyright software buy locally to have some degree of assurance about the product you are getting. |
