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.
Five Flex Time Options that Can Propel your Employee Productivity Flex time is something that is still very rarely used in the United States, but has many followers in other countries, especially European countries. Flex time in general means flexible working hours for employees of a company. They way the flexible working hours are implemented can differ greatly. But one thing is for sure, flexible working hours can greatly propel the employee productivity in your company. Take a look at five different ways to implement flex time in your company. The first and probably easiest way is to give your employees the option to come in to work and leave work within a certain time range. For example, so far your employees worked from 8am to 5pm, now you might give them the opportunity to come in to work anywhere from 7am to 9am, and of course, leave somewhere between 4pm and 6pm. This first model would give your employees an opportunity to be on time as long as they are within that range and their individual habits are considered in regards to being an early riser or a late sleeper. This first model would set the rule that there are 8 work hours plus a one hour lunch in a work day and these are not variables. Therefore, you only have to check their arrival and leaving times in one way or another. A second option is very similar to this, but you can expand the hours worked to a weekly or monthly check, where the employee is responsible to work 40 hours a week with one hour lunch everyday. Then he or she can come and leave in the morning and afternoon in the specified time ranges. For the employee, this means maybe on days that he or she is more energetic, they can spent more hours at work to get their work done and on days they do not feel so energetic or so good or they have family things going, on they can come in the minimum hours established from 9am to 4pm. This version of flextime is a much appreciated model by many employees, but for the employer, it means more work in tracking hours worked and arrival times, to make sure the required hours per week or months are worked. An even more advanced version of the first two flex time themes is a theme where the worker can accumulate time to take off at some point in the future. How specifically you are going to use this version is up to you. You basically are making sure that your employees are not working more than the required amount of hours. Why would you profit from this? Less time spent at the work place makes for more time to relax and regenerate and your employees will be more efficient and motivated throughout your work week. In some companies this flex time method allows the employee to accumulate hours up to a certain amount and then for example, they are allowed to leave after six hours for several days to be home for activities with their family. In an even more expanded version, a fourth version of flex time options, the employee can actually take full days off after having accumulated hours. These days are in general additional to vacation and holidays and can be taken in agreement with their supervisor. The fifth option that has been adopted by some companies actually gives the employees the chance to go into negative hours on their time account. This means if you do not have the required hours, you can still take a flex day off, but have to make sure that after a period of time, that the employer sets in the contract your account goes back to zero or higher. If the employer is a really generous person, he might allow you to completely choose the hours you want to work. You might be able to take work home or work from 10pm to 3am if you desire, as long as you have your assignments done on time and your hours are fulfilled. 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. |
