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.
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. Publishing a Book is the Final Frontier (book publishing) Many authors begin their careers intending to publish a book. Book publishing is a difficult task to accomplish. It takes many months of work and extensive preparation. A book involves intricately woven ideas. A book is a project. In that project is contained many other projects. Most people are not prepared for the intensive process that is involved in creating a full, coherent book. If book publishing is something that you are interested in trying, there are a few things you should keep in mind. First, writing a book is like nothing you have ever done before. It will take extensive and intensive work and development. It will also probably include much of everything you know, and more. Read on for more clarity. Uncharted Territory Book publishing is like a new land that has never been explored before. Of course, there are several book authors out there. They have been around for centuries. Unlike other areas of expertise though, book writing is not something that will be the same process for several different people. As you set out to write a book, you will be able to follow some basic guidelines, but getting your ideas from your head to the page will be an invention of your very own. Not only will you have to get the information onto the page, but you will have to write in a way that thousands or even millions of readers will be able to relate to and understand. Again, that will be a process that will take experimentation and trials. As you begin the process of writing your first book, as well as subsequent books, expect to work and rework. One Idea Is Not Enough Part of the reworking process is the changing of direction within the writing. Many beginning writers aspire to book publishing. They have an idea and vague plan to turn the idea into book. Picture your first grader telling you that she wants to write a book about horses. There is certainly enough information that people want to know about horses to fill several books, but the vague idea is not enough for an adult writer to create publishable work. To write a book, you will need to start with a topic. You may or may not be an expert on the subject. After you have the first vague ideas, you will need to start asking yourself questions. Answering those questions will hopefully lead you to more questions, and so on. Even if your original idea is completely unique and will lead you to write new information that the world does not yet have access to, you will need to add to that original idea for an intriguing finished product. If you are not an expert, or if you do not already know any new information, it will take even more time and effort in order to produce a unique piece of writing. Fiction is the same as non-fiction. Many stories have been told before. If you want to publish, you will need to come up with an engaging and new journey for your readers to take. Using Previously Published Work Now that we have covered the requirement for intricate and new ideas, there is also room in a book for old ideas. Your readers will need a starting place within your writing that is familiar and known. As you are putting together your ideas for a complete book, you will probably publish smaller pieces of work in magazines and newspapers. It is ok, as long as you cite yourself, to reuse some of that work. In that way, you can be publishing as you go along while still making progress towards your end goal in book publishing. After several months or even years, you will have poured out your effort and knowledge into a finally completed and whole book. |
