System Tray
In one of the tips I wrote last week, I happened to mention the term "system tray" and without thinking much about it, I figured most computer users know what that is. Well, when I got back into the office on Monday, I had quite a few e-mails from you all asking me about it. So, evidently I was wrong and I want to take this time to apologize for never writing a tip on it before. It should have been covered way back in the very beginning. Hopefully, some of you will be able to forgive me after today though!
Alright, so what is the system tray? Basically, the system tray is located at the very bottom of your desktop in the taskbar (which is the long bar that runs all the way across your desktop). If you look along the taskbar, you'll see some icons in the quick launch area, then you have some open space for any programs, etc. you have open and then on the very far right, you'll see where the system tray sits.
The system tray contains the clock icon, the volume icon and various other icons, depending on what all you have installed on your computer. Usually, your antivirus program icon will be there, it's where your printer icon shows up, your modem icon is there, the safely remove hardware icon sits there and so on. If you need to use any of the items in your system tray, all you have to do is double click on the icons and the programs will open. So, as you can see, the system tray is home to a lot of important applications on your PC. And now you know all about it. Yes!

some basics—definitions
Let's go over some basics—definitions that is.
I'm sure you've come across words and acronyms on the Internet that you don't know the meaning to. You may even see them every day but find your eyes glazing over with indifference to their definitions. If you plan on building your own website then it would be helpful to know what some of this stuff means. For example, do you know what the bold parts of the following web address stand for?http:// www .worldstart. com
I'm not going to get technical with the explanations. You just need the gist of it, otherwise you may end up with the TMI Blues.
TMI = Too Much Information ;-)
Okay, here we go:
Internet – a networking infrastructure (a really humongous infrastructure) where any computer can communicate with any other computer as long as they are both connected to the Internet.
WWW – World Wide Web. Not the same as the Internet. It's the way to access the information on the Internet. It's like your secret password decoder ring that allows you to tap into the info on the Internet and interprets it into a format that you understand
HTTP – stands for Hyper Text Transfer Protocol. It's an agreed upon method for formatting and transmitting messages on the WWW
HTML – Hyper Text Markup Language. It's the language used to build websites. Next time you are on a website go to your browsers menu and choose View, then Source. A window will open showing you the html that is used to put that site together. It's not very exciting to look at unless you're a programmer and like that kind of thing ;-)
FTP – stands for File Transfer Protocol. This is what you will use when your site is complete and you transfer your web pages to a server so they can be accessed by the Internet.
Domain Extensions that are available to the public:
.com = commercialWorldstart uses a .com extension ( http://www.worldstart.com/) because we are a commercial business
.net = network
.org = organization
.info = information
.biz = business
.name = name
.pro = professional
If you remember from last week, I looked up the domain I wanted which was http://www.lilydog.com/and it was already taken. I chose to alter the name a bit and see what else was available. However, I could have kept the ‘lilydog' and looked to see if a different extension such as ‘lilydog.biz' or ‘lilydog.name' was a possibility.
The following extensions are not available to the public. You have to be a part of that specific institution in order to use its particular domain extension.
.gov = government
.mil = military
.edu = education
.aero = aerospace
.coop = cooperatives
.museum = museums
Hope this clears some things up. Check out http://www.webopedia.com/ if you want more specifics. It's a great online dictionary that is geared specifically to computer and Internet definitions.

Organize Your Website
Before you jump right in to build your website, take a few moments to arrange it in an orderly, logical way. I don't know about you, but I hate it when I go to a website and all the information, and I mean all of it, is on the main page.
I realize that people are excited about their information and they want it all up front. However putting everything on one page just makes it hard to read. There is too much going on for visitors on your site to focus on any one thing. This is especially true if you make someone scroll down forever to view your info. Also, having all your info on one page makes that page load a lot slower.
So, organize your information into different pages and provide the links to these pages from the main page of your site. By providing links to the other pages, you let the user choose which information they want to see. Your main page should have the links to the other sections of the site and a bit of information that describes the purpose of the site.
I'm going to stay with the example of a site dedicated to my dog Lily to demonstrate the organization and building of a site. I want the site for Lily to include information on how I got her, what type of dog she is, some pictures of her, some of her favorite things and activities, and how about weekly diary or something like that. Yeah, a weekly diary sounds like fun because it will be a page where the information gets updated frequently. A site with frequently updated information gives visitors a reason to come back again and again. I'm going to break down the information that I just listed into different pages for the site. Here's how it will look:
Main Page
-About Lily (what type of dog, how I got her)
-Photos (photos of Lily, her family, friends)
-Lily's Picks (favorite toys, food)
-Weekly Report… (diary page, updated weekly)
Okay, that's enough. I'm going to put these pages into a tree diagram. A tree diagram is nice because it shows the layout of the site and how the pages should be connected to each other. This isn't such a big deal when there are only 5 pages total but if you have 30 pages it becomes very helpful. Here's how this looks when you put it into a tree diagram.

Here is what the site tree would look like if I added a few more pages. Let's say I'm adding two pages in the Photos section, two in Lily's Pick and one in About Lily.
Okay, the site is organized and I have a plan for the layout, so now it's time to design it. Next time we meet I'll show you some design basics, tips and some tricks. So, until then, do your homework and have your site organized
difference between CDs and DVDs
Q:Can you please explain the difference between CDs and DVDs? And how about their ROM drives? Are they really all that different?
A: I sure can and yes, they are! There seems to be a lot of confusion when it comes to these two types of media. These days, most computers come with both a CD ROM drive and a DVD ROM drive and because of that, I think a lot of people assume that you can use either drive for either type of disk. Well, that's just not the case. Yes, the drives are the same size and shape, but that's where their similarities end. Let's check out some of these differences and get all of this cleared up, shall we? Here we go!
For starters (and this is the biggest difference), DVDs have seven times the capacity that CDs do. If you're not sure, that's quite a bit! Now, I know you're probably thinking, "How can that be possible?" Well, DVDs use more layers than CDs and the way DVDs are written is quite different as well, which is a huge booster for the DVD's capacity size.
Now it's time for a little background information. CDs and DVDs both store their data in little grooves that run all around the disk. Our CD and DVD ROM drives then scan those grooves with a laser beam, which is how we're able to listen to music or watch a movie on our computers. They both also work with lands (reflective bumps) and pits (non-reflective holes), which help to represent the digital information the CDs and DVDs need in order to work.
With that said, DVDs work with much smaller pits than CDs. Basically, the smaller the pits, the more data you can fit onto the disk and that's how DVDs overcome CDs in terms of available space. As a matter of fact, the normal pit length for a DVD layer is 0.4 and for a CD, it's 0.834. Also, the tracks along a DVD are a lot closer together than on a CD, so that allows for more tracks per disk. As you can see, all of this information runs together to give a DVD a lot more room than is allotted on a CD.
This is also where the biggest difference between the CD and DVD ROM drives comes into play. Because DVDs work with such smaller pits, etc., they need a special drive that will be able to read them. Therefore, a DVD ROM drive cannot read a CD and vice versa (a CD ROM drive cannot read a DVD). That is why most computers these days are coming with both drives already installed. So, while it may seem a little wasteful, now you know why it's necessary!
Want to know some more differences? Well, like I said earlier, the layer sizes for CDs and DVDs are quite different as well. Along with DVDs having several more layers than CDs, they're also much thinner. This helps when the laser beam inside the drive is reading the DVD. DVDs also come with double sided layers, which obviously, allow for more information all the way around.
Another big difference is that DVDs can access data a lot faster than CDs can. They also have a better error correction method. And one last difference is the recording format these two types of media use. DVDs record using the Universal Data Format (UDF) method and CDs are not compatible with that type at all. The UDF format allows DVDs to store data, video, audio or a mix of all three onto a single file structure. That file can then be accessed by any drive or computer. CDs just can't say the same.
Now, I know it may sound like DVDs are the best option when it comes to certain things, but don't forget that there are times when a CD is just what you need. Sometimes DVDs are just too much and a simple CD will do. Either way, these two media formats are very convenient and handy for all of our recording needs. You have to give props to both of them for all they do!
