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.
Networking Ideas to Land a Job You Want Finding a new job is always a chore, especially if you are looking for your ideal job. While all jobs have pros and cons, finding employment that you enjoy or feel strongly about can greatly improve your job satisfaction. There are many ways to network and find the job you want. One of the biggest ways to make connections is to volunteer or find an internship. If you have not been able to land a permanent position in the career of your choice, apply for internships or offer your services for free. This is an ideal way to get your foot in the door and since the employer will already be familiar with you, it increases your chances of being hired when an opening arises. Meet people in the field you want to be in. If there are conferences or organizations that members who work in your desired field join, see about getting a membership or attending. Networking within your field of choice can build connections that blossom in the future. Take a lesser position at the company you want to work at. If you want to be a manager but are offered a customer service position, take the customer service position. Management roles are less stressful when you know what the company expects from you. Watch and learn the ins and outs of being a manager at that particular company. After you have some experience under your belt, apply for the next opening. Ask around. Most job openings are not posted anywhere. Finding openings is typically more about inquiring than finding posting. If you are eager to be a part of a company, e-mail your resume to the Human Resources department and see what type of hits you get. Stop by local companies and inquire in person and leave a copy of your resume if there are openings. Most employers are using the Internet to find new employees. Even if the position they are hiring for is not posted online, searching through posted portfolios is commonplace. The best way to get noticed is to have a concise portfolio that goes into detail about past work experience and your future career goals. Before you make it to an interview, the employer should already have a good idea about whom you are. Having a web presence is essential to job-hunting these days. Many employers are using e-mail and electronic submissions to screen employees. With that in mind, you need to be Internet savvy. Brush up on Internet skills, learning the tricks and trades of using the web as a way to seek out the best jobs. Purchase a domain and post your portfolio there. Be sure to show versatility, accomplishment and organization in your portfolio. Also if you choose to use social or networking sites represent yourself in a positive light. Be sure to keep your portfolio updated even when you are not actively looking for work. An interested employer could choose to contact you based on your updated portfolio. Be open to relocating. Search through Internet job postings for other states. Leaving your hometown might be difficult but the job of your dreams may be out there somewhere. Pack up and move to a more economically viable area and mingle with the populous. Make your employment intentions known without seeming desperate for a job. No matter what type of job you have been dreaming of, there are numerous ways to get that position. The key to pinning down, and getting the job you desire is to never give up. If you have been on the job hunt for two years without any success, do not give up.
Writers Block: What Causes it and How to Overcome it (writers block) If you are a writer then you know what I am talking about. You have everything ready, a drink, a snack, the topic, and even reference material. You sit down ready to start typing or writing, which ever you prefer, and it happens. You are stuck, your mind is blank and you have no idea how to fill that blank canvas in front of you. It is a writer?s worse nightmare come true. You have writers block. First you need to figure out what is causing it. There are a multitude of things that can be causing it. Stress is one of the biggest factors that cause writers block. Whether it is stress caused by personal matters, deadline dates, or fearing your article won?t be good enough it can block the words from flowing as easily as the should. Sleep deprivation doesn?t let your mind function to its full potential. Getting a good night?s sleep is imperative to having a clear mind and being able to focus. The project itself could be causing the writers block. A topic you are not interested in can easily turn your normally resourceful mind into jelly. The research on that topic turns into a grueling task. Then trying to put the words on paper that make sense and will peak someone?s interest seem impossible. If a topic has personal meaning to you it can be hard to write objectively about it. A simple informative topic can easily become a personal rant session. Writing because you have to, not because you want to makes it hard to concentrate and focus. Now that the basic causes have been covered, you need to know how to fix it. Writers block is not permanent. Identifying the reason is the hard part. Relax. The world is not going to end if the article isn?t as perfect as you feel it should be. Just because you don?t think it is perfect doesn?t mean someone else won?t. Go and read some of your previous writings. Even if what you read has nothing to do with your current topic, it can be inspirational to you. Don?t burn yourself out on a topic. Try to split up the writing process. Research and brainstorm one day and write the next. This will give you time to think about your topic and figure out the angle you want to write. Talk your way through it. Call a friend or colleague and chat. Tell them the topic you are working on and get their opinions or ideas. They may be able to offer fresh insight and ideas. Work on multiple projects at one time if you can. Bouncing back and forth between a few topics can keep your mind hopping and will keep boredom at bay. Take a break from you current project and write about something that motivates you. Chances are once you get those creative juices flowing they will continue into your next project. Make yourself a schedule and stick to it. If your schedule says 500 words by noon, write your 500 words and stop. Even if you don?t have a project going, by writing daily you will stick to your schedule and keeps your imagination going. If you write from home, which most of freelance writers do, make a quiet time and treat it like a real job. If you have young children at home, write while they nap. Let your answering machine be your secretary. If it is important they will leave a message. Most importantly remember why you started writing in the first place. Even the best of the best have gotten writers block at one time or another.
