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.
What to Think about While Choosing a Writing Desk (writing desk) Writing desks come in many shapes and forms. The technical definition is a piece of furniture with a surface for writing, with drawers and pigeonholes for writing materials and a portable case that when opened forms a surface on which to write. A writing desk could be as complex as that definition or as simple as a desk for writing. Basically a writing desk can be anything that you want it to be. You may not need to buy a writing desk. You may be perfectly comfortable with one you already have or working on the couch or at the kitchen table. This is fine. If it is a cohesive work environment for you that is fabulous, but some writers require a more formal, dedicated area just for them. By finding the perfect writing desk, you are on the way to the start of creative that work style atmosphere that they need. Before you begin your writing desk shopping venture you must first have two things picked out. The area in which your desk is going to go and the chair you are going to use. The location of the desk is important because it will be necessary to choose a size and style. The chair is important for comfort and maybe an important factor in determine the correct height of desk needed. Once these are figured out you shopping journey is ready to begin. While shopping for a writing desk the most important feature is comfort. You need to sit at the desk for most likely for hours at a time. Having a desk at the right height is imperative to this. With the writing surface being to high or to low will not only be uncomfortable but also will more that likely make it difficult for you to concentrate and write. Having a writing desk that is not the correct height is likely to cause neck and back strain. The function and the size of your writing desk are the next factors you need to consider before you purchase one. Do you need one with a little storage or a lot? Does it need to have an adjustable surface or can it just be flat? With all the choices available assessing what you need can help narrow down the ones that will work for you. How big of a space do you have for it? These are some simple considerations that are often forgotten while buying a writing desk. It would be terrible to fall in love with a desk and bring it home just to find out that it is not going to fit. The next important thing is style. When choosing the style of the writing desk you will want it to flow with the furniture already in your home. If your home is modern or contemporary you may want to choose one of the metal and glass desk designs or perhaps one with light wood tones and metal accents are right for you. Another great writing desk available is called the secretary. The secretary is wooden desk with drawers on the bottom and a fold down writing surface. They are usually compact in size but have ample storage and often offer shelving covered by glass doors on top. Plus having a fold down writing surface, it is easy to close up when you are done and hide you space altogether. Choosing the writing desk that is right for you may not seem that important. I mean how difficult could it be to choose a surface to write on, right? But making sure comfort, storage, and style fit into your lifestyle is an important decision. This is part of creating a suitable working environment for you to produce your work.
