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.
The Definition of Writing Styles Depends on Who is Defining Them (writing styles) While researching this topic, you may have found many different answers to what are the different types of writing styles. No two answers were the same. They range anywhere from your personal way of writing that is your writing style to formal and informal. Many people feel the best answer to what writing styles are the those will be outlined below in this article. You can decide for yourself if this definition suits your. The term creative writing covers a range of writing areas. Poetry, fiction books, short stories, and screenplays are considered creative writings. Any writing in which is not strictly non-fiction would be classified as such. Journalism and news reporting are forms of Expository writing. The purpose is to focus on one topic and inform the reader by provided the facts. These writings can be seen in the forms of travel brochures, professional journal, business reports, and new paper articles. Descriptive writing is what gives you the mental pictures of what we have read. It uses a lot of adjective and adverbs to describe things. When descriptive writing is very good you can close your eyes and know exactly what the author is saying. The kind that makes you taste what the characters and see what they are seeing. Analytical Writing is a writing that focuses on a topic and then verifies the purpose of it. It is often taught school age children through out the years because it is something they will use in their life. Book reports, conference papers, thesis, essays, and dissertations are all academic writing. It is created using a third person point of view and deductive reasoning supported by facts. Its purpose is to show a clear understanding of a subject by presenting information. Technical Writing is used in owner manuals, how to guides, magazine articles, and design specs just to name a few. Its purpose is to take complicated technical information and turn it into something the intended audience can understand. Technical writing usually deals with electronics of all sorts, chemistry, robotics, and finance. Any kind of writing that has to do with business matters is considered business writing. It is concise and to the point. Your intended audience wants to know what happen and why, but with minimal detail in between. An active voice is necessary in business writing. It keeps people focused and shows that you are in control of situations. Correspondence is the writing of memos, letters, or emails between people. It is a message that is sent between two people or groups of people. To provide facts and statistic and having the ability to influence your readers with your words is persuasive writing. This is used for products ads, political campaigns, or any kind of promotion. It is not necessary to prove why something is else is wrong or bad you just need to prove why your promoting is better. Narrative writing is use to tell a story or list of events that have already happen, might have happened, or could happen in the future. These writings may include novels, poetry, short stories, or a number of other things. A lot of times many of these styles are meshed together in our writing. Business writing and technical writings are often one in the same as are academic writing and analytical writing. With the overlapping of the styles it hard to define one writing style from another, you can guess it is all a matter of the point of view you are looking at it from and your opinion. Movie Copyright Law College Students Are Being Targeted For Breaking Movie Copyright Law Many people have taken up the hobby of downloading movies and songs on the Internet and sharing them with their friends and family online. However, this is direct violation of the movie copyright law. Not surprisingly, the biggest violators of the movie copyright law are students. It is not surprising that the movie industry sector is sending out copyright infringements claims to college universities around the country. One reason that college students may be the hardest hit when it comes to violations brought against them for infringing on movie copyright law is that they are not aware of how serious a crime it truly it. Many college students who have suits brought against them are shocked, to say the least. They question why they were not warned about the perils of downloading movies and songs online and passing them along to friends. However, with the rise of claims that are being handed down, no one can claim ignorance for much longer. Word is being spread near and far that if you are engaging in illegal downloading and/or sharing then you can be brought to court. College students are learning the hard way that it is against the law and in violation of the movie copyright law to share or download copyrighted material. Many colleges and universities are now stating in their handbooks that it is against the law and the university rules to illegally download movies, music and other forms of media online using a school computer. In addition to illegal downloading and sharing software, the files take up space on the computer systems and use a considerable amount of bandwidth. While most universities and colleges will not look at the content an individual has -- they can isolate and identify the individuals who are hogging up the bandwidth by using illegal file sharing software. The movie and music industries have stepped in and are demanding restitution for illegally downloaded movies, music and other forms of copyrighted media. They have detection agencies that have the technology to identify and trace copyright infringements straight to their source. Once the computer is located they can notify the university or the college that they are in violation. The university will be told that they have a copyright infringement claim against them. Based on the Digital Millennium Copyright Act once the computer is isolated Internet access is terminated to that computer and court proceedings can begin. Does this sound far fetched? Well, it is not. You should know that in April of 2003 four students were sued by Recording Industry Association of America. These students attended Princeton, Michigan Technical University and Rensselear Polytechnic Institute. One student alone had an estimated liability of $150 billion. When you consider that you can be charged $750 per song that is illegally downloaded, the total can add up fast! The good thing is the lawsuits against the college students were settled for amounts less than $20,000. That is not pocket change for college students – or anyone for that matter! Movies and music are meant to be enjoyed. However, illegally downloading movies and music is not much different than walking into a video store and sticking DVDs and CDs in your pocket. Be careful. You do not want to be caught violating the movie copyright law. |
