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.
Copyright music free Getting Copyright Music Free can Pay the Artists There are few people that will allow you to use their copyright music free. If you've found a person or a business that is willing to allow this then either consider yourself extremely lucky or start searching for the very fine print. Most people feel a certain kindred or passion for the music they like and they aren't overly willing to part with it at all unless they feel it is their calling to share this music with the world. In those circumstances you will be amazed at how eager they are to share their "message". I however, worry more about those that are eager to share than I worry about those who say no rather quickly and without sending another thought your way. Call me crazy but I'm usually the first one to give my things away and to share when I don't really have that much to begin with. I believe in sacrifice and the need for giving to those who have less or those whose needs are somehow not being met. This makes me a prime candidate for those who would ask me to share my copyright music free. I'm afraid my answer to that question is almost always going to be a no of my own. That being said I've always held a special fondness for musicians. Perhaps it's those teen crushes from which I've never fully recovered-ahem-2 or 3 years later. The problem today is the people are downloading copyright music free online without regards to the fact that when they get it free, someone isn't getting paid for their talents, efforts, and hard work. There are alternatives that will allow you to download the music really cheaply or pay a subscription fee for a service that allows you to download all the music you want for one set amount each month. These services allow the talented writers and performers of this music that adds so much to our lives each and every day to get paid for their labor. Paying for the music in this manner also allows us to enjoy that music while cutting out the middlemen and markups we often pay when purchasing music at retail prices. You do not have to get copyright music free in order to enjoy a wonderful bargain and when you pay something for your music you are ensuring that these talented writers and performers will find it profitable to continue providing this music that entertains you so much. We all enjoy getting things for free or feeling as though we've gotten a terrific bargain. That is one reason that subscription services are so wildly popular. You pay one price for the privilege of downloading as much music as your hard drive and modem can handle each month. It's like paying one fee and enjoying copyright music free except that you are actually paying for the music you are getting in other ways. More importantly though, the artists, writers, and recording companies are getting a piece of the profit pie, which keeps them in business. After the recent problems involved with massive and illegal downloading of copyright music free, recording companies began putting their proverbial feet down and demanding that action be taken. The solutions have been quite clever and highly effective. Consumers were much more willing to pay a monthly subscription fee that amounted to the amount of money that one CD would cost in order to download unlimited music from their homes. Record companies are getting paid for work that has already been done without the need actually produce, deliver, transport, and market their new CDs. This is copyright music free in its best form for all involved. Got Java on the Brain? Get Free Coffee Products!
