The saved user ID/Password pairs are stored in the Registry under a key whose default permission settings make it inaccessible to all users-even the user to whom the passwords belong. Only the system itself has direct permission to read and change Registry data under this key. Using RegEdit you could modify the permissions on that key and read its contents, but doing so still wouldn't reveal anything useful, as the data is thoroughly encrypted.
On the other hand, once you've logged on to your account in Windows, all of your saved passwords can be utilized by anybody who has physical access to the computer. The interloper can't learn what the password is, but can use it to log on automatically. If you allow Windows to save passwords for you, never leave your computer logged on when you're not sitting in front of it. Either choose Log Off from the Start menu or lock the computer—on many systems you can do this by pressing the Windows key plus L for Lock. As a backup, set the screen saver to kick in after just a few minutes of inactivity, and check the box for password protection.
So, there is a certain amount of risk in letting IE save passwords. Here's how to turn off that feature, if you so choose. Select Tools | Internet Options from IE's menu, click the Content tab, and click the AutoComplete button. Click the Clear Passwords button in the resulting dialog to clear out passwords that were previously saved. Then uncheck the box titled User names and passwords in forms, click OK, and click OK again.

It's all about getting your site listed on top in Search Engines i.e Search Engine Optimization
First thing you need to do is find the keywords you want to optimize for.
There is great tool by Overture (http://inventory.overture.com/d/sea...ory/suggestion/)
But I would suggest using this free tool called GoodKeywords (http://www.goodkeywords.com/products/gkw/)
This one does the same job as Overture does but it also supports other Search Engines (Lycos and Teoma etc..)
For example if you want to optimize for the keyword "tech news", just search for the keyword in any of the tools specified above... It would show you keywords related to that and not of the searches..
Pick the keywords which are related to your site.
For example when you search for "Tech News" you'll see the following results:
Count Search Term
11770 tech news
351 itt news tech
191 high tech news
60 news tech texas
49 computer tech news
42 bio news tech
34 in itt news tech
30 news tech virginia
29 asia news tech
25 hi tech news
25 sci tech news
Now see what other terms are related to your keyword technology news
Do couple of searches like that and note down around 15-20 keywords.
Then, keep the keywords which are searched most on the top.
Now you need Title Tag for the page.
Title tag should include top 3 keywords, like for "tech news" it can be like :
"Latest Tech News, Information Technology News and Other computer raleted news here."
Remember that characters should not be more than 95 and should not have more than 3 "," commas - some search engines might cosider more than 3 commas as spam
Now move on to Meta Tags
You need following Meta Tags in web page
<meta equiv="Content-Type" content="text/html; charset=iso-8859-1">
<meta name="keywords" content="keyword1,keyword2,keyword3">
<meta name="description" content="brief description about the site">
<meta name="robots" content="Index,Follow">
No need to have other meta tags like abstract, re-visit and all, most people dont read it.
Now...
<meta equiv="Content-Type" content="text/html; charset=iso-8859-1">
This tag is tells content type is html and character set used it iso-8859-1 there are other character sets also but this is the one mosty used..
<meta name="keywords" content="keyword1,keyword2,keyword3">
This one should have all your keywords inside starting from keyword with most counts...
keyword tag for our example would be something like :
<meta name="keywords" content="tech news,technology news, computer technology news,information technology,software news">
Remember to put around 15-20 keywords max not more than that. Dont repeat keywords or dont put keywords like, "tech news", "info tech news", "latest tech news" and so on...
<meta name="description" content="brief description about the site">
Provide short decription about your site and include all the keywords mentioned in the title tag.
Decription tag should be:
<meta name="description" content="One Stop for Latest Tech News, Information Technology News, Computer Related and Software news.">
It can be upto 255 characters and avoid using more than 3 "," commas
<meta name="robots" content="Index,Follow">
This is used for search robots..following explanation will help you :
index,follow = index the page as well as follow the links
noindex,follow = dont index the page but follow the links
index,nofollow = index the page but dont follow the links
noindex,nofollow = dont index page, dont follow the links
all = same as index,follow
none = same as noindex,nofollow
Now move on to body part of the page
Include all top 3 keywords here,
I would suggest to break the keyword and use it...
For example
YourSiteName.com one stop for all kind of Latest Tech News and Computer Related information and reviews.................
Include main keywords in <h#> tags <h1><h2> etc..
and start with <h1> and then move to <h2> <h3> etc..
<h1> tag will be too big but CSS can help you there, define small font size in css for H1,H2,... tags
When done with page copy, then you need to provide title and alt tags for images and links.
Use some keywords in the tags but dont add all the keywords and if not neccessary then dont use keywords in it, basically it should explain what is image all about.
Remember to add Top keyword atleast 4 times in the body and other 2 keywords thrice and twice respectively.
Now move on to Footer Part
Try to include top keywords here and see the effect, use site keywords as links i.e.
<a href="news.php">Tech News</a> <a href="software-news.php">Software News</a> etc..
Now finally, you need to read some more stuff..may be you can all it as bottom lines...
Site Map - This is page where you need to put all the links present in your site, this is will help Search Engines to find the links easily and also provide link for site map in footer, as search engines start scanning the page from bottom.
Robots.txt - This file contains address of directories which should not be scanned by search engines.. more info can be found here : http://www.robotstxt.org/wc/exclusion.html search engines line google, yahoo ask for robots.txt file.
Valid HTML - Your code should have valid html and doc type, Its kind of diffucult to follow all the standards but you can atleast open and close all the tags properly, you can check your page's html online here : http://validator.w3.org/ or you can use this free software called HTML Tidy : http://tidy.sourceforge.net/
All done now, you just need to check your site with this script, its called SEO Doctor : http://www.instantposition.com/seo_doctor.cfm
It'll show you the report of your site with solution.
Now, correct the errors and start submitting the site :
Start with google : http://google.com/addurl.html
then yahoo : http://submit.search.yahoo.com/free/request
then move to altavista,alltheweb and other search engies..
Also submit your site to direcories like http://dmoz.org , http://jayde.com etc...
Dmoz is must, as google, yahoo and may more search engines uses same directory
And remember, dont try to SPAM with keywords in these directories, dmoz is handled by Human Editors
Submitted the sites, but still i cant see you site on top?
Wait for sometime may be a month or so but keep an eye on your search term, use http://GoogleAlert.com - this will show whenever google updates for your keywords, it will mail you the new results.
And also check whether your site is listed on google..
use this tool called Google Monitor, it can be downloaded for free from : http://www.cleverstat.com/google-monitor.htm

Bandwidth Explained!

Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is bandwidth as it relates to web hosting? Put simply, bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet. The amount of bandwidth a hosting company can provide is determined by their network connections, both internal to their data center and external to the public internet.
Network Connectivity
The internet, in the most simplest of terms, is a group of millions of computers connected by networks. These connections within the internet can be large or small depending upon the cabling and equipment that is used at a particular internet location. It is the size of each network connection that determines how much bandwidth is available. For example, if you use a DSL connection to connect to the internet, you have 1.54 Mega bits (Mb) of bandwidth. Bandwidth therefore is measured in bits (a single 0 or 1). Bits are grouped in bytes which form words, text, and other information that is transferred between your computer and the internet.
If you have a DSL connection to the internet, you have dedicated bandwidth between your computer and your internet provider. But your internet provider may have thousands of DSL connections to their location. All of these connection aggregate at your internet provider who then has their own dedicated connection to the internet (or multiple connections) which is much larger than your single connection. They must have enough bandwidth to serve your computing needs as well as all of their other customers. So while you have a 1.54Mb connection to your internet provider, your internet provider may have a 255Mb connection to the internet so it can accommodate your needs and up to 166 other users (255/1.54).
Traffic
A very simple analogy to use to understand bandwidth and traffic is to think of highways and cars. Bandwidth is the number of lanes on the highway and traffic is the number of cars on the highway. If you are the only car on a highway, you can travel very quickly. If you are stuck in the middle of rush hour, you may travel very slowly since all of the lanes are being used up.
Traffic is simply the number of bits that are transferred on network connections. It is easiest to understand traffic using examples. One Gigabyte is 2 to the 30th power (1,073,741,824) bytes. One gigabyte is equal to 1,024 megabytes. To put this in perspective, it takes one byte to store one character. Imagine 100 file cabinets in a building, each of these cabinets holds 1000 folders. Each folder has 100 papers. Each paper contains 100 characters - A GB is all the characters in the building. An MP3 song is about 4MB, the same song in wav format is about 40MB, a full length movie can be 800MB to 1000MB (1000MB = 1GB).
If you were to transfer this MP3 song from a web site to your computer, you would create 4MB of traffic between the web site you are downloading from and your computer. Depending upon the network connection between the web site and the internet, the transfer may occur very quickly, or it could take time if other people are also downloading files at the same time. If, for example, the web site you download from has a 10MB connection to the internet, and you are the only person accessing that web site to download your MP3, your 4MB file will be the only traffic on that web site. However, if three people are all downloading that same MP at the same time, 12MB (3 x 4MB) of traffic has been created. Because in this example, the host only has 10MB of bandwidth, someone will have to wait. The network equipment at the hosting company will cycle through each person downloading the file and transfer a small portion at a time so each person's file transfer can take place, but the transfer for everyone downloading the file will be slower. If 100 people all came to the site and downloaded the MP3 at the same time, the transfers would be extremely slow. If the host wanted to decrease the time it took to download files simultaneously, it could increase the bandwidth of their internet connection (at a cost due to upgrading equipment).
Hosting Bandwidth
In the example above, we discussed traffic in terms of downloading an MP3 file. However, each time you visit a web site, you are creating traffic, because in order to view that web page on your computer, the web page is first downloaded to your computer (between the web site and you) which is then displayed using your browser software (Internet Explorer, Netscape, etc.) . The page itself is simply a file that creates traffic just like the MP3 file in the example above (however, a web page is usually much smaller than a music file).
A web page may be very small or large depending upon the amount of text and the number and quality of images integrated within the web page. For example, the home page for CNN.com is about 200KB (200 Kilobytes = 200,000 bytes = 1,600,000 bits). This is typically large for a web page. In comparison, Yahoo's home page is about 70KB.
How Much Bandwidth Is Enough?
It depends (don't you hate that answer). But in truth, it does. Since bandwidth is a significant determinant of hosting plan prices, you should take time to determine just how much is right for you. Almost all hosting plans have bandwidth requirements measured in months, so you need to estimate the amount of bandwidth that will be required by your site on a monthly basis
If you do not intend to provide file download capability from your site, the formula for calculating bandwidth is fairly straightforward:
Average Daily Visitors x Average Page Views x Average Page Size x 31 x Fudge Factor
If you intend to allow people to download files from your site, your bandwidth calculation should be:
[(Average Daily Visitors x Average Page Views x Average Page Size) +
(Average Daily File Downloads x Average File Size)] x 31 x Fudge Factor
Let us examine each item in the formula:
Average Daily Visitors - The number of people you expect to visit your site, on average, each day. Depending upon how you market your site, this number could be from 1 to 1,000,000.
Average Page Views - On average, the number of web pages you expect a person to view. If you have 50 web pages in your web site, an average person may only view 5 of those pages each time they visit.
Average Page Size - The average size of your web pages, in Kilobytes (KB). If you have already designed your site, you can calculate this directly.
Average Daily File Downloads - The number of downloads you expect to occur on your site. This is a function of the numbers of visitors and how many times a visitor downloads a file, on average, each day.
Average File Size - Average file size of files that are downloadable from your site. Similar to your web pages, if you already know which files can be downloaded, you can calculate this directly.
Fudge Factor - A number greater than 1. Using 1.5 would be safe, which assumes that your estimate is off by 50%. However, if you were very unsure, you could use 2 or 3 to ensure that your bandwidth requirements are more than met.
Usually, hosting plans offer bandwidth in terms of Gigabytes (GB) per month. This is why our formula takes daily averages and multiplies them by 31.
Summary
Most personal or small business sites will not need more than 1GB of bandwidth per month. If you have a web site that is composed of static web pages and you expect little traffic to your site on a daily basis, go with a low bandwidth plan. If you go over the amount of bandwidth allocated in your plan, your hosting company could charge you over usage fees, so if you think the traffic to your site will be significant, you may want to go through the calculations above to estimate the amount of bandwidth required in a hosting plan.
