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.
Copyright music Copyright Music in Order to Protect Future Profits If you are a budding artist seeking to copyright music that you have labored over, there is good news. Many people confuse copyrighting music with registering music and they are two different things. According to the law in the United States, once you have written or recorded your music in a permanent form, it is copyrighted. Of course, it might help to first understand what it means to copyright music in the first place. A copyright is a certain legal protection that is offered to those who compose creative works. Whether those works be art, music, or the written word. According to the U. S. constitution there are limits that can be placed on the amount of time that the work is exclusively protected. If you copyright music, this means that you and you alone have the right to use your work or allow others to use your work. You also have the right to distribute copies of your work. Whether those copies are in the form of written or sheet music or recorded music to the public as well as the right to perform your music for the public. There is something called fair use that despite your copyright; music written or recorded by you may be used for the purpose of research, news reporting, commentary, or criticism. In other words, there are times when the use of copyrighted material is deemed appropriate without the consent of the one holding the copyright. To copyright music alone is not enough in many cases to protect your music, at least not without going through a lot of hoops in order to do so. One of the things you can do in order to protect your copyright is provide notice of copyright. This is a simple step that includes writing a simple statement to the effect of the word "copyright", the date, and your name at the bottom of your sheet music or on the case for the recording or the actual recording itself. CD's are the most common means for recording devices today and a notice of copyright can easily be added to the exterior of your CD or on your label if you have one printed. In case you are wondering: why copyright music? The answer is rather simple, so others cannot take credit for your creative genius. For an added layer of protection you may want to consider registering your copyright as well. Registering your copyright will provide you with formal legal documentation of your ownership of your music should anyone else attempt to lay claim to your music or any other dispute about true ownership/authorship come about. You must have your copyright registered if you wish to file a copyright infringement suit and it is, in my humble opinion, better to not only copyright music early on but also to register your copyright before it could possibly become an issue. Registering while not entirely painless is not as difficult a process as you might think. Basically it involves filling out an application, paying a filing fee (check with the U. S. Copyright Office for the current amount), and a copy of the work being protected (this will not be returned). It's also important to remember that your music doesn't have to be published in order for you to obtain a copyright. Music should be copyrighted and registered long before the publication process in order to protect your rights as the creator of the music. Whether you are dabbling with cute little limericks or writing masterpieces and concertos or are rock and rolls next super star you want to make sure to copyright music earlier rather than later for the best possible outcome should problems arise. Technical Writing: What is it? (technical writing) Technical writing is one of the most difficult forms of writing. To be a technical writer you need to be able to convey a technical message in a concise and effective manner. Technical documents must be created using comprehensive and precise information in a brief and understandable style. You will need the ability to be able to correspond with technical experts and have the understanding of all technical terminology. You are the middleman between the designers, engineers, or scientists and the audience of the technical writings. You have to have the ability to under stand what they are saying and the turn it into something that can be understood by someone else. Simply put it is writing that designs, creates, and upkeeps any kind of technical data such as user manuals, how to guides, and online help just to name a few. To be able to achieve a career in technical writing you must be able to write complex data in a straightforward, easy to understand and articulate fashion. You must be able to word step by step instructions in a way that seems effortless to a consumer. While doing technical writing one of the most important aspects of your job will be creating for an intended audience. So not only must you understand and convey what you are writing, you must understand whom you are writing it for. In most cases, you are generally trying to explain complex technical information to the average person. But with the diversity in the world today and having such a vast potential audience you must understand the meaning of the words you use and what they could mean to someone else. Some technical writing projects may also include magazine and newspaper articles. These articles will probably be focused on new technologies and products. In some cases this may be in the form of an advertisement. Or it could just be an introduction to a new product saying hey this is what we have and this is what it a can do. Although a formal education is always a plus, if you have experience and successful past ventures in technical writing it isn’t always necessary. Knowledge into the multiple components needed for technical writing is required. They key components to what you must know is an in depth knowledge many software programs. These applications can include Visio, Quadralay Web Works Publisher, Microsoft Word, and HTML script writing. Proper formatting, style, and organization of writings are what make them easy to follow. Correct wording, clear sentences, and easy terminology make your technical writings easy the read and comprehend. If you are employed as a technical writer with a company, you will most likely be working with a team of other writers. You writings will be reviewed for content efficiency as well as any grammar and spelling errors. Depending on the structure of the team they may be working on the same project as you or they may be working on separate projects. Either way the team is assembled as a support group to help make your technical writing be as accurate, effective, and as simple as it can be. To succeed in technical writing these are the simple rules to follow. Keep it as simple as possible; no one wants to read four pages to find a simple one word answer. Understand the people you are talking to and what you are telling them. If you don’t understand, neither will they. Make sure you get your work proofread or read it aloud to make sure it makes sense. You know what you are trying to say, but your reader does not. You are the carrier for getting information from point A to Point B. |
