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.

Turning your Eye to Government, Nonprofit or Small Business for you Next Job The type of business you work for can effect your job satisfaction. Your personality type may also work out better at certain types of businesses. Research different business types before going on your job search. Working for a small business or a non-profit definitely has its pros and cons. First of all, getting hired at a small business can be much easier than landing a position than at a corporation. Typically you will only have to go through one person to get the job. Usually the small business owner conducts the interview. This can be a good thing because the business owner may be willing to overlook a lack of experience or extenuating circumstances concerning your work history. Nonprofit jobs are often easier to get if you are passionate about the cause. The person that is doing the hiring is generally passionate about the cause that the nonprofit is working to assist. If they pick up on passion about the cause from you, typically you will get the job. However, that passion is necessary because they pay may not be very much. Working for a smaller company also opens up more opportunities for promotions. With fewer employees and contact with the owner, you may be able to move up in the company faster. You will be able to pick up on skills in less time than at large corporations, which often have many hoops for one to jump through before training for a new position. There may be a smaller window of time to pick up on new skills because of the limited amount of time that can be put towards training. Nonprofits may not have as many opportunities for promotions and job stability may be questionable. If the donations stop coming in or whoever funds the nonprofit decides not to fund it anymore, you could be out of a job. This is a very real concern with a nonprofit job. There are some drawbacks to working at smaller businesses. Sometimes, the staff at smaller businesses have been in place for years. New, younger employees may not be viewed favorably. This could affect working relationships with co-workers. Smaller companies also mean smaller paychecks. Independent businesses are not able to generate large paychecks. This could make staying at a small business undesirable. However, the personal interaction between you and your boss could be encouragement to stick it out with a small business. Or the opposite could be true. Government jobs can be beneficial to have for a number of reasons. First of all, government jobs offer good salaries and great benefits. You will have all government holidays off and you will be working in a position that is necessary to the maintenance of the government. That means that you probably won’t have to worry about being displaced. Although, remember that if the government runs into tough times, layoffs are possible. Government jobs are usually normal business hours but not always. There are some positions that will have hours that extend a little bit beyond regular business hours but for the most part, you will be able to enjoy your life by taking advantage of vacation time. Sick days will also be available at government jobs. Some of the drawbacks of government jobs are that you may have to deal with a large amount of on the job stress. You may be responsible for processing hundreds, maybe even thousands of cases and one mistake could be very tragic for an individual. Depending on what your position is, you may be instrumental in handling paper work from a huge amount of people.

Keeping your Career Intact During Maternity Leave Since, for the most part, maternity leave in this country is not paid, the reality of returning to work after having a baby comes much sooner than it does in most countries. No one wants to return to absolute chaos after they have the baby. Cut down on the stress of going back to work by being prepared. The length of your maternity leave can determine the amount of stress you return to. If you are willing and able it is a good idea to work as long as possible. Of course, everyone is not willing and able. For those that need a longer leave, they should put some plans in place to make the transition back to work smoother. How long you are on maternity leave varies. However, if you plan on returning after you have the baby, you do not want to return to a totally chaotic situation. That means that you want to have the needs of your career in tact before you take your maternity leave. Nothing should interfere with your new addition to the family. While you are bonding and spending time with your newborn you do not want the stress of the office hanging over your head. Lay the ground work so that you do not have to worry about the office while you are away. If you are the boss, you have a lot more stress to manage. It is important that you leave a responsible and capable person in charge of things in your absence. Start training that person to deal with the aspects of your job that they will have to handle as soon as you know you are pregnant. Nothing is more annoying than getting “How do I…” phone calls when you are on maternity leave. If your job is massive, split the responsibilities between two employees. You do not want to split up the tasks among too many people because this can lead to confusion. Two should be the maximum. Be sure to leave things in order. If you are not the most organized person, get that way when you find out you are pregnant. While you are on maternity leave anyone should be able to walk into your office and find what they are looking for in a very short amount of time. If things are messy there is more of a chance for things to go wrong. If you are one of those women that needs to have an extended maternity leave because of pregnancy complications, don’t fret. Enjoy your time offer and relax but also, if you can, try to stay on top of what is happening in your career field. Take an online class and brush up on skills. If you are not sure you want to return to your 9-5, research a new career. The Internet has made working from home a very real and popular option. Search for a job that will allow you to stay at home but also bring in some income. Some jobs, such as Computer Programming, can fetch a pretty penny. Do some research and find out what will suit you best. Work part time until you are ready to have the baby. While some women are eager to take their maternity leave, others are not so excited about it. If that is the case, talk to your employer about working part time until you are due. Some women work until they go into labor. There is no need to do that if you are uncomfortable but if you are having an uneventful pregnancy and love your job, why not?
