What is bandwidth,the exact meaning


This is well written explanation about bandwidth, very useful info.

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.

RealMedia Trick: See all episodes in one go


Today I was watching Dragonball series but was just irritated that after every episode I had to close that episode and double click another episode to see :/ so here I used this trick 😉

Use notepad to open a new file, type this inside:
file://link to file1
file://link to file2
(type as many as you want)
Close file. Rename it to FileName.rm

Then you`re done!!!!

Ex:
I put my playlist file here: C:\Movies\7VNR
And the movie files are in C:\Movies\7VNR\DragonBall

Then inside my playlist file I`ll have something like this:

file://DragonBall/db134.rm
file://DragonBall/db135.rm
file://DragonBall/db136.rm
file://DragonBall/db137.rm
file://DragonBall/db138.rm

Isn’t it a cool method? 😀 share it with your friends and keep reading my articles :))

10 Security Enhancement Tips


I was thinking about pc security and it resulted into this article

Before you spend a dime on security, there are many precautions you can take that will protect you against the most common threats.

1. Check Windows Update and Office Update regularly (_http://office.microsoft.com/productupdates); have your Office CD ready. Windows Me, 2000, and XP users can configure automatic updates. Click on the Automatic Updates tab in the System control panel and choose the appropriate options.

2. Install a personal firewall. Both SyGate (_www.sygate.com) and ZoneAlarm (_www.zonelabs.com) offer free versions.


3. Install a free spyware blocker. Our Editors’ Choice (“Spyware,” April 22) was SpyBot Search & Destroy (_http://security.kolla.de). SpyBot is also paranoid and ruthless in hunting out tracking cookies.

4. Block pop-up spam messages in Windows NT, 2000, or XP by disabling the Windows Messenger service (this is unrelated to the instant messaging program). Open Control Panel | Administrative Tools | Services and you’ll see Messenger. Right-click and go to Properties. Set Start-up Type to Disabled and press the Stop button. Bye-bye, spam pop-ups! Any good firewall will also stop them.

5. Use strong passwords and change them periodically. Passwords should have at least seven characters; use letters and numbers and have at least one symbol. A decent example would be f8izKro@l. This will make it much harder for anyone to gain access to your accounts.

6. If you’re using Outlook or Outlook Express, use the current version or one with the Outlook Security Update installed. The update and current versions patch numerous vulnerabilities.

7. Buy antivirus software and keep it up to date. If you’re not willing to pay, try Grisoft AVG Free Edition (Grisoft Inc., w*w.grisoft.com). And doublecheck your AV with the free, online-only scanners available at w*w.pandasoftware.com/activescan and _http://housecall.trendmicro.com.

8. If you have a wireless network, turn on the security features: Use MAC filtering, turn off SSID broadcast, and even use WEP with the biggest key you can get. For more, check out our wireless section or see the expanded coverage in Your Unwired World in our next issue.

9. Join a respectable e-mail security list, such as the one found at our own Security Supersite at _http://security.ziffdavis.com, so that you learn about emerging threats quickly and can take proper precautions.

10. Be skeptical of things on the Internet. Don’t assume that e-mail “From:” a particular person is actually from that person until you have further reason to believe it’s that person. Don’t assume that an attachment is what it says it is. Don’t give out your password to anyone, even if that person claims to be from “support.”

Always be safe on Internet ,you never know when you would receive an attack!

Windows 8 for Gamers?


Windows 8 attracted all people because of its fascinating features.But is this true among gamers also?

Earlier Windows Vista proved to be an enemy among gamers ,choosing XP as their friend.But if we see Windows 8 rite now too its not favourite among gamers . Windows XP and 7 remain the winners.W8 is just good for freshment and new tech enthusiasts ,maybe in future games would come for Windows 8 too.

So I suggest to stay on your current OS rather then shifting to W8.

Till then keep reading.

How to RIP Dynamic Flash Template



What you need:

Sample dynamic flash template from TM website
Sothink SWF Decompiler
Macromedia Flash
Yourself

1. browse or search your favorite dynamic flash template in TM website. If you got one… click the “view” link and new window will open with dynamic flash.. loading…

2. If the movie fully loaded, click View -> Source in your browser to bring the source code of the current page and in the source code, search for “IFRAME” and you will see the iframe page. In this example were going to try the 7045 dynamic template. get the URL(ex.
http://images.templatemonster.com/screenshots/7000/7045.html) then paste it to your browser… easy eh? wait! dont be to excited… erase the .html and change it to swf then press enter then you’ll see the flash movie again icon_smile.gif.

3. copy the URL and download that SWF file.. use your favorite download manager.. mine I used flashget icon_smile.gif NOTE: dont close the browser we may need that later on.

4. open your Sothink SWF decompiler… click “Quick Open” then browse where you download your SWF/movie file. Click Export FLA to export your SWF to FLA, in short, save it as FLA icon_smile.gif

5. Open your Macromedia FLash and open the saved FLA file. press Control+Enter or publish the file… then wallah! the output window will come up with “Error opening URL blah blah blah…” dont panic, that error will help you where to get the remaining files.

6. Copy the first error, example: “7045_main.html” then go back to your browser and replace the 7045.swf to 7045_main.html press enter and you’ll see a lot of text… nonsense text icon_lol.gif that text are your contents…

NOTE: when you save the remaining files dont forget to save with underscore sign (_) in the front on the file without the TM item number (e.g. 7045) if it is html save it as “_main.html” and same with the image save it as “_works1.jpg” save them where you save the FLA and SWF files. Continue browsing the file inside Flash application so you can track the remaining files… do the same until you finish downloading all the remaining the files.

Hence done 🙂 how you liked it? Do comment 😉
