Web Hosting - The Internet and How It Works
In one sense, detailing the statement in the title would require at least a book. In another sense, it can't be fully explained at all, since there's no central authority that designs or implements the highly distributed entity called The Internet.
But the basics can certainly be outlined, simply and briefly. And it's in the interest of any novice web site owner to have some idea of how their tree fits into that gigantic forest, full of complex paths, that is called the Internet.
The analogy to a forest is not far off. Every computer is a single plant, sometimes a little bush sometimes a mighty tree. A percentage, to be sure, are weeds we could do without. In networking terminology, the individual plants are called 'nodes' and each one has a domain name and IP address. Connecting those nodes are paths.
The Internet, taken in total, is just the collection of all those plants and the pieces that allow for their interconnections - all the nodes and the paths between them.
Servers and clients (desktop computers, laptops, PDAs, cell phones and more) make up the most visible parts of the Internet. They store information and programs that make the data accessible. But behind the scenes there are vitally important components - both hardware and software - that make the entire mesh possible and useful.
Though there's no single central authority, database, or computer that creates the World Wide Web, it's nonetheless true that not all computers are equal. There is a hierarchy. That hierarchy starts with a tree with many branches: the domain system.
Designators like .com, .net, .org, and so forth are familiar to everyone now. Those basic names are stored inside a relatively small number of specialized systems maintained by a few non-profit organizations. They form something called the TLD, the Top Level Domains. From there, company networks and others form what are called the Second Level Domains, such as Microsoft.com.
That's further sub-divided into www.Microsoft.com which is, technically, a sub-domain but is sometimes mis-named 'a host' or a domain. A host is the name for one specific computer. That host name may or may not be, for example, 'www' and usually isn't. The domain is the name without the 'www' in front. Finally, at the bottom of the pyramid, are the individual hosts (usually servers) that provide actual information and the means to share it.
Those hosts (along with other hardware and software that enable communication, such as routers) form a network. The set of all those networks taken together is the physical aspect of the Internet.
There are less obvious aspects, too, that are essential. When you click on a URL (Uniform Resource Locator, such as http://www.microsoft.com) on a web page, your browser sends a request through the Internet to connect and get data. That request, and the data that is returned from the request, is divided up into packets (chunks of data wrapped in routing and control information).
That's one of the reasons you will often see your web page getting painted on the screen one section at a time. When the packets take too long to get where they're supposed to go, that's a 'timeout'. Suppose you request a set of names that are stored in a database. Those names, let's suppose get stored in order. But the packets they get shoved into for delivery can arrive at your computer in any order. They're then reassembled and displayed.
All those packets can be directed to the proper place because they're associated with a specified IP address, a numeric identifier that designates a host (a computer that 'hosts' data). But those numbers are hard to remember and work with, so names are layered on top, the so-called domain names we started out discussing.
Imagine the postal system (the Internet). Each home (domain name) has an address (IP address). Those who live in them (programs) send and receive letters (packets). The letters contain news (database data, email messages, images) that's of interest to the residents.
The Internet is very much the same.
Ten Top Things That Make for a Great Employee If there is one thing that everyone can agree upon in the job market it is that great employees are hard to come by. Whether you are an employee yourself and you feel like you are always pulling the weight of the other people in the office or if you are a boss who is wondering how you can actually get some people on board who can do the job, you know that great employees are at a premium. But what exactly makes an employee great? These ten top things are guides to bosses looking for greatness in a new hire and for employees trying to get noticed in the workplace and be the kind of employee who has the potential to move up in the company chain. The first thing that makes an employee great is that they are always dependable. Great employees do the job they are supposed to do every time, and no one has to worry that they don?t deliver the goods. A great employee can be counted to always have their work done right, when it is supposed to be done ? it is a forgone conclusion that they will, and no one else has to spend any time worrying about it. The second thing to look for in a great employee is that they are a team player. A great employee isn?t one who is constantly looking for attention or hogs the spotlight. Instead, a great employee works with everyone else to make sure that the things that need to get done do get done, for the good of the company. The third mark of employee greatness is that they know how to take direction. Great employees know how to take criticism, direction and advice gracefully and make it work for them when doing their job. Fourthly, a great employee can be trusted. They don?t spread office gossip and they don?t dish company dirt. Likewise, they always tell the truth to their employer, even if it lands them in hot water. The fifth sign of greatness in employees is linked to the fourth ? a great employee always guards the confidential nature of their business dealings and protects everyone?s privacy. The sixth thing that makes an employee great is that they participate in the day to day life of the office. They don?t bow out of meetings or skip the office birthday celebrations. These things may not be a fun part of working life, and everyone involved knows that everyone else has some place they would rather be ? but a great employee wouldn?t be any place else. In seventh place comes the fact that a great employee gets along with other employees. Every office has one person that is in everyone else?s business and talks to loud on the phone and generally stirs things up and gets under everyone?s skin. This kind of employee zaps office morale ? a great employee is a good co-worker to everyone. The eighth thing a great employee has is good working skills. It may sound obvious, but a great employee has the abilities needed to do their job, and they constantly seek ways to improve, like going to training seminars or seeking further education. Great workers have great skills. The ninth thing that leads to employee greatness is tact and decorum. If there is a problem in the office, a great employee doesn?t make a scene in front of everyone else. A great employee will deal with such issues with privacy and diplomacy. Further, a great employee doesn?t tell tasteless, political or religious jokes, nor do they send emails that tell these kinds of jokes. Last but not least, a great employee has a great attitude. Bad attitudes bring everyone down. A great employee helps make work great for everyone else by having a good spirit about their job.
