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.
Networking Know-How: How to Get Through to the Busiest of People When you are job hunting, sometimes the most frustrating part is just getting your foot through the door to let the right people know that you are out there and available for work. Companies can be like members-only clubs; they tend to be a little distrustful of cold callers and most executives advise their assistants to run interference for them on the phone so they do not get stuck having a protracted conversation with someone they just aren’t interested in doing business with. The thing is that to get an interview, these people can be the very same people you need to talk to. How do you get these busy people to clear some time off in their busy schedule to speak to you? First things first – you have to get the right attitude. If you want busy people to make time to talk to you, you have to present yourself in a way that makes them feel like you are worth the time investment. The trick here is that you have to do this by phone, and often, you have to first convince an operator or personal assistant that your call is one worth putting through to the boss. Your phone etiquette and vocal confidence will be the key here. Consider you basic phone manners first. Instead of launching right into what you want, respond to the greeting of the person who answers the phone with a hello of your own. Animate your voice and always remember that simply saying “please” and “thank you” can go a long way. Be the kind of caller that you would want to talk to if your job was answering the phone all day. People will respond to your positive attitude with a positive attitude of their own. Next, consider your confidence level on the phone. Do you tend to get tongue-tied and stumble over your words? That kind of delivery from you will set all the warning bells ringing on the other end of the phone, and you will find the person with whom you wish to speak always “out of the office.” Instead, work on sounding like you are confident that it is a forgone conclusion that you will get to speak that busy person you want to talk to. Be confident that what you have to say is something that is worth hearing. It may help to write out a framework of what you will say and practice a few times so you sound relaxed and composed when you make that call. Once your attitude is right to make the call, you can then employ a few tricks of the trade for getting through to those busy people. Instead of giving away too much up front, start your call by asking if the person with whom you need to speak is in. If the answer is yes, then you can remove on potential “excuse” for not putting your call through. If your call can’t be taken at that time, skip the message. Let the PA or operator know that you will call back again. That way you have a legitimate reason to keep calling. Of course, you might have to keep calling and calling, and that assistant might start knowing the sound of your voice. If you keep speaking to the same person, it’s time to open up with some person details. Let them know your name, why you’re calling, and if someone referred you, who that person is. Developing that personal relationship can help you get your call through to the boss. Last but not least, don’t give up. Busy people are, well, busy, and not necessarily avoiding your call. Persistence pays off, so keep on calling until you get through. Being Effective in Your Persuasive Writing (persuasive writing) The goal of persuasive writing is to have the ability to influence or change a persons mind with your words. You encounter these in your normal everyday life. Whether it is a politician trying to convince you to vote for them, a commercial for a company that wants you to buy there product, or from your children trying to explain the reason why they should be allowed to go to that concert, persuasion is all around. You may even use the power of persuasion on yourself, like deciding why or why not you should eat that last piece of pizza or if you really need to buy another white shirt even though it is a really good deal. Everyday you have to decide on whether one choice is better than another and why. To succeed in your persuasive writing venture you need to follow a few simple rules. You must have focus. Decide on what position you are trying to persuade. Are you for or against the topic your writing about? Choose a side and stick with it. Arguing both sides of the fence will be detrimental to your persuasion. There are three techniques that you will need to use to have convincing persuasive writing. Now you need to provide facts and evidence to support your writing. Statistics and examples are used to provide the reason people should choose you position and believe your writings. You can also include facts and evidence that demonstrate why the opposition is wrong. This should be eased into. Remember you are trying to persuade and convince them on why you position is better not offend or alienate them. This is called the logos technique of persuasion writing. Another persuasive writing technique is ethos. This is where you have to prove yourself to be a creditable person. To be able to make your readers believe that they should have confidence in what you are telling them. The best way to prove your credibility is to provide true and undisputable facts, be articulate, and explain why you are capable of proving this information to them. Pathos is the third technique you will use in your writing. This will appeal to the emotions of the readers. This can be the most important technique but also the most critical. It must be used with caution or you can just as easily turn the readers against you as you could bring them with you. Appealing to your readers emotions can be tricky. This must be done subtly To work this effectively you must have the ability to make the reader feel your emotions, the joy, the pain, the hurt whatever the case maybe. You need to pin point your target audience and write to appeal to them. What sounds interesting and persuasive to a teenager most likely will not work with a middle age woman. Whether you are targeting men or women will make a difference in you writings. Identify with your target audience. An example of this would be “only the cool kids will be wearing product XYZ” or “we know as a respectable home owner you will want to…..” By identifying with the intended audience it pulls them into what you are writing and how or why it pertains to them. Persuasive writings can be a challenge. You have to objective and opened minded to other positions of the topic at hand even though sometimes you don’t want too. Remembering you goal is just to persuade them why yours is better. This does not necessarily mean that the opposition is bad or wrong, just that yours is a superior choice. |
