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.
ï»żWhat is copyright infringement What Is Copyright Infringement? The Layperson's Copyright Primer Copyright laws are constantly changing, and knowing exactly what copyright infringement is, whether youâre creating an eBook, publishing articles, using music as a backtrack to your podcast - or what have you - is essential to selling your online media. Although the laws change from one jurisdiction to another, knowing the basic rules of copyright infringement will ensure youâre following the proper rules of engagement when it comes to creating your works. Before you make any final decisions regarding the use of a work that has been copyrighted, please contact a copyright attorney to ensure youâre following the law â this will keep you from being sued or, even worse, punished in a court of law. What is Copyright Infringement? Copyright infringement, as defined by Wikipedia.org, states: âCopyright infringement (or copyright violation) is the unauthorized use of material that is protected by intellectual property rights law particularly the copyright in a manner that violates one of the original copyright owner's exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative works that build upon it. The slang term bootleg (derived from the use of the shank of a boot for the purposes of smuggling) is often used to describe illicitly copied material.â So, what is copyright infringement in plain English? It means that if youâre not allowed to use something, then donât use it â plain and simple. It can be very simple to get permission to use a work â many times youâll be able to use a âsampleâ of music or excerpt of written work for a nominal fee, or small attribution. However, if you do not have the permission of the copyright holder â whether itâs an author or a publishing house â you can be sued for copyright infringement or worse. What is Copyright Infringement in America? In many jurisdictions, such as the United States of America, this act is known as a strict liability crime or tort (a tort is a civil wrong â not a criminal wrong). This means that the person who infringes the copyright - whether intentionally or not - will be responsible for the damage or loss. Also, the prosecutor (in criminal court) or plaintiff (in civil court) must only prove that the act of copying was committed by the defendant â they do not need to prove guilty intent. This means, even if you had no intention of committing copyright fraud or infringement, you can (and in present times, in many cases, WILL) be prosecuted, even if you used the material in good faith. What is Copyright Infringement in action? Many cases of copyright infringement are difficult to see to the layperson, because the violation is not limited to exact copying. In many cases, when something is inspired by another thing â such as in music, when the inspiration of one song is used to create an entirely different song â itâs difficult to see where the new product or âthingâ has crossed the line to something illegal. Some works arenât even protected by copyright, such as compilation of facts that lack the creativity necessary to be covered by copyright, or works that are in the public domain because the copyright has expired. Knowing the difference is often very difficult to see, and because of this weâve seen a number of copyright infringement cases in recent years, especially in tandem with the music industry. As you can see, copyright infringement is a very difficult, albeit necessary, act to define. However, if you make sure that youâre using works that are in the public domain, or have long since been out of copyright (think Beethoven or Frankenstein) youâll be safe. Do you fair research, and if you have any questions contact a copyright lawyer and ask âwhat is copyright infringementâ to learn the most up-to-date information for your jurisdiction. ï»żCopyright infringement case Learning Copyright Law through Copyright Infringement Cases Copyright infringement cases can be both costly and time consuming. Considering copyright infringement is something that isnât as easily defined as theft or speeding, there are numerous copyright infringement cases that are changing the way copyright law is viewed in the United States of America. By reviewing a few of these copyright infringement cases, youâll be able to get a better idea of what is, and is not, acceptable use of copyrighted works. As a forward, however, youâll need to know a little bit about copyright law. Most copyright lawsuits are brought to the courts because a copyright owner has found their copyright is being used outside the copyright laws. This usually means that the copyright holder hadnât been asked for permission to use the work, or if they had, that the work is not being used in an agreed-upon context or they have not been paid royalties. The copyright infringement cases, listed below, give a sampling of what goes to the Supreme Court in copyright infringement. Feist Publications v. Rural Telephone Service Co (6th Cir. 1996) This copyright infringement case was brought upon the Supreme Court in 1996 regarding the copyright of a database. The supreme court, in this instance, decided that compilations of data (such as in a database) are only protected by copyright when they are âarranged and selected in an original manner.â Although the level of originality needed to make the database copyright-able is not very high, the pages of a directory such as a phone book are not protect-able because the data contained therein is arranged geographically, then alphabetically. Because of this, the data was not original enough to warrant a copyright infringement charge, and the competing telephone company was allowed to tap into their competitorsâ database and use that data in their own work without liability. Princeton University Press v. Michigan Document Services, Inc (6th Cir 1996) This case has to do with the âfair useâ law, which is defined in the Copyright Act of 1976, 17 U.S.C. § 107. In this case, a photocopying service was sued for copyright infringement for making âcourse packsâ for the University of Michigan. In this case, a course pack was a group of reading materials assigned by a professor â then the course pack was bound together by a professional copy shop. In the fair use system, there is a system available for payment of copyright fees to publishers whose works are used in course materials, the printing shop owner refused to pay the copyright cost. When it went to the Supreme Court, they analyzed the fair use code and found that it was NOT fair use, and the printing shop had to pay the copyright costs. As you can see, copyright infringement cases are cases in which someone violates the rights of a copyright owner, as provided by 17 USC §106, or of the author as provided in §106A. These copyright infringement cases can be taken to either criminal or civil court, and can carry with it a hefty fine. Copyright infringement cases are brought upon people who violate copyrights every day. In recent times, youâll find many copyright cases in relation to electronic copyrights â such as those youâd find on a website or PDF file, as well as other digital media such as music and audio files. Itâs probable that youâve seen copyright cases brought against the common person â such as a child or family â for downloading digital music in the form of MP3s. In the current internet age weâre in, itâs not surprising to see so many music and video copyright cases brought to us because of peer to peer file sharing made possible by the internet. You can be certain that until people know the rules of copyright, and downloading copyrighted material from the internet that weâll see many more copyright cases. |
