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.
Patent and copyright law Understanding Patent and Copyright Law Patent and copyright law gives the inventor the exclusive rights to the invention. No one else can produce the invention for a set period of time under patent and copyright law. Patent and copyright law is set up to protect inventors. The law on patents can be found in the United States Constitution, Article 1, Section 8 and in Title 35 of the United States Code. The agency that is in charge of patent laws is a Federal Agency known as the Patent and Trademark Office. Anyone who applies for a patent will have their application reviewed by an examiner. The examiner will decide if a patent should be granted to the inventor. Individuals who have their patent application turned down can appeal it to the Patents Office Board of Appeals. Just because someone has a patent does not mean that they have the right to use, make or sell the invention. For instance, if a drug company comes up with a new drug, they can get a patent on it. However, it would not be available to be sold to the general public until the drug becomes approved by other regulatory bodies. Likewise, someone may invent an improvement to an existing product, yet they will not be allowed to produce or sell the item until they obtain a license to do so from the owner of the original patent holder. For someone to receive a patent, as stated, they must fill out an application on their invention. The application will entail the details of the invention and how it is made. In addition, the person applying for a patent must make claims that point to what the applicant deems or regards as his or her invention. A patent may have many claims with it. The claims protect the patent owner and notify the public exactly what the individual has patented or owns. If someone infringes upon patent and copyright law, it is usually enforced in a civil court setting. The owner of the patent will generally bring a civil lawsuit against the person who has infringed upon their patent and ask for monetary compensation. In addition, the patent owner can seek an injunction which would prohibit the violator from continuing to engage in any acts that would infringe upon their patent in the future. Many patent owners will make licensing agreements (or contracts) with others. These agreements allow another person or company to use someone’s patented invention in return for royalties. In addition, some patent holders who are competitors may agree to license their patents to each other to expand both of their profits. Most everything we use in our day to day life was invented by someone. That person had to seek out a patent for their invention. Patent and copyright law protects inventors from having their ideas and inventions stolen out from under them. This makes the playing field more level for individuals. Without these laws, the marketplace would be out of control and the small guy would probably be eaten alive by big business To-Do Lists an Important Part of Being a Better Employee What makes a good employee? Take a look at how the star employee in your office operates. Chances are that they don’t run around in a constant fog of stress and pressure. Good employees are usually calm and conscientious; they seem to always get the job done with a minimum of hair pulling and frantic rushing around. Is it just genes that these people have that allow them to work like this, or are some people just better at managing stress than others? The answer is probably not. If you take a closer look at the star employee in your office, you will are likely to see that they are so stress free and productive because they are good at managing their time. And chances are they manage that time with the help of a to-do list. The to-do list is an often-overlooked part of working life. While they are the kind of thing people expect housewives to carry around with them in their purse while they run errands, many people think they can do without them in the work place. This is a big mistake. Being productive at work is all about being able to carry out your tasks in a timely manner, and being productive at work is also about managing your stress. If you are too stressed out, your work will suffer for it. You will fall behind because you won’t be able to concentrate, and you will make mistakes you might not have made if you were able to take your time with your work. So, how can a to-do list help? To-do lists can do many things for you in your busy working life. For starters, to-do lists remove the problem of having that all important phone call or meetings slip your mind. When you have a to-do list, everything that needs to be accomplished is set out there for you, so there is no more explaining to your boss why you stood up your company’s most important client. With a to-do list, you can also see the bigger picture of everything that needs to be done, so you can plan your time wisely. Working on tasks one after another as they come up is not a smart way to accomplish things at the office. Some jobs are on a tight deadline, while other jobs can stand to wait a little while. When you set everything out for yourself in a to-do list, you will be able to prioritize your tasks in order of importance, so you get the crucial work out of the way first thing, and only move on to less important jobs when you have the time to devote to them. All of this organization will make your working life less stressful. Imagine a typical day without a to-do list. You come in to the office in the morning, you work through all of the email sitting in your inbox, you make a few phone calls, chat with some co-workers in the break room, answer a few more emails, and then bam! All of the sudden, you remember that the presentation your boss needs for the big meeting is due at 2 p.m., and you haven’t even started it. Now you resort to hair pulling and frantic working. Then, you give your boss the presentation over an hour late, and it is filled with mistakes and sloppy work. Now imagine the same day with a to-do list. You get the presentation out of the way first thing, and you have time to check it. Then you can move on to less important tasks without the dark cloud of stress hanging over you. To-do list writing is time well spent if you want to succeed at work. |
