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.
Web Hosting - All About Domain Names "What's in a name?" Shakespeare asks in Romeo and Juliet. In the case of your web site the answer is: quite a lot. A domain name is the English (or other) language designator for your site. Because of the way the Internet functions, that name is associated with an IP address, a numeric identifier that computers and network components use to connect a browser to a web site. It's not mandatory that a site has a name. But directing visitors by IP address can quickly generate difficulties. Having an IP address IS mandatory, since it's ultimately the way a web site is located by other computers and network software. In the early days of the Internet the name was chosen carefully in order to help a person remember the URL. That made it easier to type, too. With hotspots on a page, great search engines, social networking and other contemporary tools, that's not as important now. But from a marketing perspective, it still helps to have a good name. It's still beneficial to have a site called 'CheapTVs.com' if what you sell are inexpensive TV sets. Calling your site, 'InexpensiveElectronicVisualDisplayDevices.com' may describe your business in some way, but it's a little harder to refer a new person to your site. Which name you choose can, therefore, affect how much traffic your site gets, how soon. Sooner or later, if you have information and/or products/services that people want, word will get around. But having a good name can certainly help. Love them or hate them, the Google company chose well. Of course, the fact is that there are millions of web sites around the world. That means, you don't necessarily get the name of your first choice. ICANN (Internet Corporation for Assigned Names and Numbers) is the internationally recognized authority for managing IP addresses across the worldwide Internet, along with the top-level domain name-parts (.com, .net, .org, .edu, and so forth). But registering a name is done by simply contacting any of a hundred organizations that work as intermediaries to establish and track the names. GoDaddy, Register.com, Network Solutions and a great many others provide the service for anywhere from free to a few dollars per month or year. You contact them by navigating to their web site. Then, using a feature they all provide, you can select a possible name. They use something called whois and other software to determine if the name is already claimed. Or, you can check yourself at www.whois.com. Registration is for a limited time, but typically renewable in perpetuity provided you pay the (usually annual) fee. You may have to go through several choices to find a domain name that isn't already in use. With so many millions of sites, the odds of you getting your first choice is slim, unless you have a highly unusual imagination. But, it's also true that domains tend to die or expire. As they do, the name becomes available for use by someone new. A method for getting on a 'waiting list' is available. You register the name you want and if and when the name becomes available, you are offered the chance to claim it. Naturally, there's competition even on the waiting list for 'good' names. There are many different ways of establishing priority that vary by company. At any given time there are thousands of so-called auctions going on to bid on names. Give some thought to your new domain name and research its availability, but don't stress over it. The name isn't everything. After all, if Google had built a search engine that delivered usable results only 10% of the time, their name would be mud.
