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.

Following Up on Fallacies about Getting Free Stuff “Free stuff” – the mere whisper of the words is often enough to make many people throw common sense out the window and head for the free goods like a missile to a target. And then there are those people whose eyes glaze over when they hear those words, because they can’t believe anything worth having can actually be free. The truth about free stuff is really somewhere in the middle. Yes, you can really and truly cash in on many freebie deals for things that you want to have, but a healthy sense of cynicism about free gear is also useful. Here are some of the important things to keep in mind about free stuff. The first myth you should throw out the window is that nothing good comes for free. The fact of the matter is that the price tag on a good doesn’t always match up to the quality, and there are many great free things out there. Case in point: music. Sure, everyone has heard the scare stories about file sharing online, and maybe some big record labels will come after you if you focus on their artists. Dig a little below the surface, however, and you can find a whole new world of really great bands that are more than happy for you to listen to their music over and over again. The same goes for free software. People on the cutting edge of technology who have a passion for creating new and efficient applications often develop open source code software. They’re doing it for the love of it, and they often have more talent than any ten suit-and-tie tech guys trying to hock their latest product for a mega profit margin. Here is where the reality part comes in, however. Yes, you can find wonderful things that are completely free – but yes, you can also find a lot of free things that aren’t worth your time at all and in some cases can cause you a lot of trouble. The net is a great place to fall victim to a “free stuff” scam, but you can also sometimes come across these scams in the mail as well. If something is free, but requires you to give your credit card number or bank details, run the other way. Another myth people have about free stuff, especially free stuff on the internet, is that when you try to cash in, the only free stuff you will be getting is an inbox full of more spam than you can handle. The truth about this is, well, that is can certainly be true. Many companies give away free things in exchange for your email address, so they can try to hit you up to purchase things in the future. What makes this a myth, however, is that it can be avoided. If you don’t want to choke on an inbox of spam, and who could blame you, set up a special (free) email account that you will use exclusively for freebie hunting. You’ll have the best of both worlds. The last myth about free stuff involves the “catch” people are always looking for. Often, for free stuff, the catch is a bit of junk mail or email or the fact that you have to submit to a time consuming survey. Sometimes, the catch is that if you get free stuff through a trial offer, if you don’t cancel it, it keeps coming, and this time you have to pay. The truth about these catches is, however, that the catch is in the eye of the beholder. These things don’t make products any less free; so don’t write off every free offer offhand. You might just find a catch you can live with to get a great free product you really want.

The History of Writing (history of writing) Writing is commonly used by billions of people each day. However, many of us don’t know the history of writing, and some of us would rather not ponder it for fear of getting a headache. Written communication is much needed today, and many societies could not survive without writing. Writing has a history like everything that is in existence today. The exact history of this form of communication may be clouded and even over exaggerated at times, but there are two known facts, writing has been used for a very long time and writing will be used for a very long time. The true beginning of writing is unknown, but it does have a comprehensive history. The first artistic paintings and writings were said to be done in the form of naturalistic paintings of animals and people in caves. The pictures were known as attempts to appease the spirits of animals that were needed to kill in the hunt. In ancient times pictures were also done of human beings. These pictures of humans were typically done in series, with a figure appearing in different physical positions progressively, which represented positions a ceremonial dance performed by ancient people. Progressively, the early societies began to stylize their messages, which were similar to using symbols to represent restrooms, handicap-accessible places, and international road signs. These stylized symbols are known a petroglyphs and hieroglyphs. The most famous system of hieroglyphs belonged to the ancient Egyptians who had hieroglyphics that were partially representational pictures that were stylized. Petrogylphs were often used by Native Americans as messages along trade routes, ritual information, and various other things. However, they were not as sophisticated as hieroglyphs. During this ancient period, Europeans preserved esoteric knowledge in runes and in an alphabetic writing system known as ogham. The Chinese culture also has a place in the history of writing. The culture began by writing like many others by using pictures then slowly moving to stylized pictures. However, over time the pictures became less representational and more abstract. Today, Chinese, Japanese, Korean, and other Asian languages are written with the use of ideeographs. An ideeograph is used to represent an idea instead of a word. Around 1700 B.C. a new form of writing appeared in the Middle Eastern cultures. During this time, the Phoenicians created an alphabet. This development was different from all others because the symbols represented sounds, not pictures or ideas. The combinations of sounds made up the words of the language, which was crucial in the history of writing. The alphabet developed by the Phoenicians spread to Northern Africa and became the system of the Arabs, and spread northwest to Greece. The Greek developed their own letters, which were modified even more to become the Cyrillic alphabets of Russia, the Balkans and the Romans. The Romans modified the alphabet and made it the alphabet that is recognized today. The history of writing developed even further into the 20th century. Following World War II, the Japanese and Chinese began to use the alphabet to represent the sounds of their languages. For these Asian cultures, the alphabetic system was easier to write by hand and to print economically, so it made life far simpler for those cultures. The artistic form of writing used by these Asian cultures will likely never die, but there are many advantages to using an alphabetic system, and many modern people of these cultures benefit handsomely from learning to read and write using the current alphabet. The history of writing is long and sometimes vague, but it can be seen as a necessary teaching that will help modern societies understand the importance of written communication, and understand how the world would be forever changed without it.
