What is BitTorrent

BitTorrent is a content distribution protocol that enables efficient software distribution and peer-to-peer sharing of very large files, such as entire movies and TV shows, by enabling users to serve as network redistribution points. Rather than having to send a download to each customer requesting it, the distributor or holder of content sends it to one customer who in turn sends it to other customers who together share the pieces of the download back and forth until everyone has the complete download. This makes it possible for the original server to serve many requests for large files without requiring immense amounts of bandwidth.

BitTorrent's protocol has been described as a "swarming, scatter and gather" file transfer protocol. It was written in the Python programming language by Bram Cohen and is distributed freely under an open source license.

What is Joomla?

Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone.

How Install Joomla on your Computer.

Joomla is one of the most popular and powerful Content Management System today. It has wide range of features which makes you feel you are lost somewhere within joomla without knowing what to do next. If you are a beginner, you can always start by reading the Quick Startup Guide or you can also download a podcast so that you learn some basic functions easily.

But learning Joomla which is installed your web server is a painful task. Since you know very little thing, you may require to work back and fourth to get the job done. It takes your time and you will be wasting your bandwidth as well. Especially if you are on slower internet connection, then it will be pathetic task to learn Joomla which is installed on your web server.

So the only solution to overcome this problem and headache is by installing Joomla on your computer (localhost), so that you can save a lot of bandwidth and can work faster and easier and most of all, offline – hassle free!

Since Joomla is a Sever-Side script, you need to install three essential software which enables you to install Joomla on your computer. Those three softwares are PHP, MySQL and Apache Server. PHP is server-side scripting which is used to create Joomla and whereas MySQL stores all the data such as articles, sections, posts, comments and pages etc. And Apache server is a web server and it is responsible to deliver the output on web browser.

Instead of installing all these applications individually, you can just install a program called WampServer 2.0. For linux you can install software called LAMP or the LampServer. And for MAC you can install MAMP Server.

WampServer stands for Windows Apache MySQL PHP Server. Which means it installs all those applications at one time easily. Installing WampServer on your computer doesn’t require you to be a Rocket Scientist. All you need to do is just download and install it in few clicks. By default, WampServer 2.0 will be installed in your “c:\wamp”. And if you have installed WAMP5 earlier, you need to uninstall it before installing WampSever 2.0.

After you install WampServer on you computer, your windows firewall may ask to block or unblock, just unblock it. In order to test whether if the WampServer is installed properly or not, launch the WampServer from your desktop or All Programs. The WampServer runs in your system tray.

Now open your web browser and type http://localhost in your address bar and hit return key. That should take you to the “Server Configuration” page

Installation of Joomla.

Before installing Joomla! on your WampServer, you need to create a MySQL Database to store the tables.

To create a MySQL database, go to your Server Configuration page by typing http://localhost in your web browser’s address bar. Now click on the link called “phpmyadmin” under “Your Aliases”. Now you will be taken to the phpmyadmin page. Under “Create new Database”, enter a name of your desire and click on Create button.

Now you have finished creating the database. Since you did it in few steps and on the localhost, your database username will be “root” and your database password will be blank.

Now download the latest version of Joomla! by clicking on this link. And extract it. Rename the folder called “Joomla-1.x.x” to whatever you wish, like “mygreatjoomla”. This will make easy for you to remember the path to enter whenever you want to open your Joomla site from your computer.Copy and paste that folder in “c:\wamp\www”. so that it must make the path like this,

Quote:
c:\wamp\www\mygreatjoomla\
Now open your web browser and type the URL of your joomla folder in the address bar. It must be like this, http://localhost/mygreatjoomla.

This will take you to the Joomla! installation page:

Follow the steps and remember the database settings must be like this:

Hostname: localhost
Database Password:
Username: root
Database Name:
Follow the remaining steps and after the installation is complete, go to http://localhost/mygreatjoomla in your favorite web browser to starting learning Joomla!

What is WAMPServer?

WAMP is a form of mini-server that can run on almost any Windows Operating System. WAMP includes Apache 2, PHP 5 (SMTP ports are disabled), and MySQL (phpMyAdmin and SQLitemanager are installed to manage your databases) preinstalled.

An icon on the taskbar tray displays the status of WAMP, letting you know if; a) WAMP is running but no services are opened (the icon will appear red), b) WAMP is running and one service is opened (the icon will appear yellow) or c) WAMP is running with all services opened (the icon will appear white). Apache and MySQL are considered to be services (they can be disabled by left-clicking on the taskbar icon, guiding your cursor over the service you wish to disable and selecting "Stop Service").

The files/web pages that are hosted on your WAMP server can be accessed by typing http://localhost/ or http://127.0.0.1/ in the address bar of your web browser. WAMP must be running in order to access either of the above addresses.

If you would like to share your files/web pages with others, click on the icon located on your taskbar tray and select "Put Online." You must have access to the Internet in order to continue.
You can download WAMPServer from WampServer.com.

What is Network?

A network or communication network is a system of interconnected communication devices that can communicate with one another and share information. Therefore computer network can be defined as:
A system in which more than one computers or large number of computers are interconnected together, communicate freely with one another and share information is called computer network.

A network can be internal to an organization or span the world by connecting itself to the internet. In computer network, network operating system is used that controls and co-ordinates the activities of computers that are connected to the network. The example of these operating systems are: windows NT, UNIX, and Novell etc.

Types of Network

Networks are of three types. These are:

* Local Area Network (LAN)
* Wide Area Network (WAN)
* Metropolitan Area Network (MAN)

Local Area Network

A local area network is a network system in which computers are interconnected in a limited geographical area, such as network of computers in college computer laboratory or network of computers in office building etc.

Wide Area Network

A wide area network is a network system that covers a large geographical area such as different cities of country or different countries of the world. In WAN telephone lines, satellites, microwave, fiber optic etc. are used as transmission media.

Metropolitan Area Network

A Metropolitan area Network is a network system that covers area of a single city. Usually, MAN connects more than one LANS in a city or town and covers a smaller geographical area than a WAN. The cable television, telephone companies or local corporations use MAN.

WEB SERVERS AND WEB HOSTING

So you’re looking to learn about web hosting and what it has to offer or you may not know much about web hosting? There is no shame in not knowing this information. Everyone has to start at the beginning at some point. On that note, lets begin learning about web hosting.

First off, what is web hosting and how does it work?

Web hosting is the business practice of providing space and bandwidth on a high-powered computer server that is connected to the Internet at very high speeds. Hosting companies maintain large networks of high-powered web server computers in a physical location known as a data center. These computer servers are connected to a very fast, and generally redundant, Internet connection. The data centers have primary and backup power, a fast connection to the Internet, and a security monitoring staff.

The web hosting companies provide a share of disk space and available bandwidth to a customer for a monthly fee. Once the customer is signed up, they can upload files to their personal space on the web server and the information is then viewable to anyone interested on the Internet. The monthly fee the web hosting company charges is much less than what it would cost to run a server out of your own home or data center. This is the reason these companies exist. They take care of all the hardware, software, and other technical needs for you.

Types of web hosting

There are many different types of web hosting offers, but the main three are shared, reseller, and dedicated. Each type of hosting is for a different purpose.

Shared Web Hosting

Shared web hosting is the most popular form of hosting. Shared hosting is a portion of disk space and bandwidth provided to you by the web hosting company on a high-powered server. There are many other web sites hosted on this server, and the hosting company is likely to have quite a few of these servers in a large data center. The resources of the server are shared by as many other websites as are allocated to that computer.

Shared web hosting is the best form of web hosting if you are looking for a great price and don’t have more than a couple thousand daily visitors to your site.

Reseller Web Hosting

Reseller web hosting is a popular, low-cost solution to starting your own web hosting business. There are two types of reseller hosting, private-label and a reseller of services.

The private-label is the best type of reseller plan because it allows you to retain full control over your customer’s websites. A private-label plan allows the reseller to keep the full monthly payment of the web-hosting customer, but the reseller must pay a monthly fee to the larger hosting company for the reseller space. The more hosting accounts a private-label reseller can sell, the higher the profit for them. Private-label hosting allows you to host many more websites than if you were using shared hosting for each. This is a great solution for someone who has many sites they need to host in one location to save money.

The reseller of services plans resell the regular web hosting plans of a larger web hosting company, but you get a discounted price for providing the customer and earn a monthly fee for as long as they remain a customer. This plan does not allow control over customer web sites and you only keep a portion of the potentially monthly revenue.

Dedicated Web Hosting

Dedicated web hosting is the most powerful and cost effective solution of hosting a busy web site without resorting to buying your own equipment and paying hundreds of dollars per month for a fast Internet connection. Dedicated hosting consists of single server with no one else hosting on that computer. This allows for the greatest of configuration options. Anyone who has a busy website will find dedicated hosting is the necessary choice.

Web Hosting Considerations

Wondering about all the other information listed in web hosting plans? In this section, I will explain the most important considerations in choosing a good web host.

Price

The price of web hosting services is one of the most important. There are many hosting companies out there with cheap hosting packages, but they may be lacking in other areas. Don’t let the price of a hosting package fool you. There are some hosting companies out there who have great prices and the other features are just as good. Price may be one of the most important decisions of a web hosting plan, but there is much more to consider in choosing a quality web host.

Disk Space / Storage Space

Disk space is the amount of physical storage space a web host gives to you to store your web files. Hosting companies these days have plans with disk space being measured mostly in terms of gigabytes, but some are still offering plans in the megabytes for storage space. Depending on your needs for file storage space, you may need more or less. Generally the more disk space offered, the better.

Bandwidth / Data Transfer

The amount of bandwidth available can make a big difference in choosing a quality hosting plan. In general, the more bandwidth a hosting company makes available to you, the better. This means you can support more traffic to your web site as your business grows. Be wary of web hosting companies that offer unlimited or unmetered bandwidth. While many of these are legitimate offers, there are some out there who are overselling their bandwidth in hopes the average user won’t use much.

Customer Support

In any business, it is very important to provide exception customer service. Web hosting is no exception to this. Many of the hosting companies are available all day and night in case you have a problem with your web site, but there are some who are just available specific hours of the day. If your web site goes down in the middle of the night when they’re not available, this means lost revenue for a business. You should make sure the web host you select is always available for support.

Money Back Guarantee

Most web hosting companies will provide a thirty-day money back guarantee. Some will provide one even long, but be wary of the ones who offer no money back guarantee. I would not purchase web hosting services from a company who does not offer at least a 30 day money back guarantee, unless they have proven themselves to be a leader in the industry and have an excellent reputation.

Operating System

An operating system is a piece of software that controls the interaction between the computer user and the physical hardware of the machine. A vast majority of all web sites on the Internet run on the Linux operation system. Linux is generally much more stable than Windows. Stability is critical in running a web site. For this reason, I prefer to host my web sites on the Linux operating system. Some sites have specific requirements that only the Windows operating system can satisfy, but there are always alternatives to those requirements.

Backup

A good web hosting company will have a regular schedule to backup the data on all the web servers. The more often the data is backed up, the better. At the very least, a web hosting company should backup web site files daily.

Control Panel

The control panel is the point of contact the web site administrator will have between the host server and their own machine connected via the Internet. It is essential to have a well organized and easy to use control panel interface. My favorite control panel is cPanel, which is one of the leading web hosting control panels out there today. Plesk is another good one, and many companies will create their own control panel for you to use. Most web hosting companies will provide a link to a demo of the control panel they use with their hosting plans. The control panel used is a matter of preference, but it should be user friendly.

Email

Email is essential part of communication on the Internet. Most web hosting companies out there will give you more email addresses and more space to hold email messages than you will ever need. What you need to watch out for is the companies that have decided to be a little strict on their email accounts and only offer a small number or a small amount of message space.

Uptime

Uptime is a term used to describe how often the average web site hosted by a company is available online. No company should be expected to provide an exact 100% uptime. This is impossible due to things such as hardware, software, and power failures. A vast majority of the companies are very good with uptime, and they guarantee it. It is still a good idea to be conscious of the uptimes posted by the company. If it is not at least 99.5%, it is probably not worth hosting with that company.

Statistics

As a webmaster, it is nice to know how many visitors you’ve had, where they came from, how long they stay on your site, and how much bandwidth they’ve used. This information is collected by the web server and is placed in a log file. A statistics software package can read this data and provide meaningful information to the webmaster. The information gathered from these logs can be very valuable in improved services to the viewers of the web site.

FTP

FTP stands for file transfer protocol. It is a way of quickly uploading or downloading many files to and from a web server. Most web hosting companies will allow their customers access to their web hosting accounts via FTP. FTP is very useful and is a great feature to have when paying for a web hosting account.

Scripting

Since the World Wide Web began, many scripting languages have been created and have evolved into the dynamic and interactive environment we enjoy today. A scripting language is a way of adding functionality to a web site, whether it be to calculate numbers or to load information from an external database. Scripting languages have made electronic commerce possible. Some of these languages include PHP, ASP, JSP, Coldfusion, VBscript, Javascript, and Perl. I won’t go into the details of these in this article for the sake of complexity. If you know how to use these languages, you should know what to look for in a web server for them.

Databases

A database is a place to store data that can be used in a large variety of ways. Databases are used on the Internet for applications such as shopping carts, message boards, and product catalogues. The more databases the web hosting provider allows you to create, the most applications you can deploy on your web server. Databases are used by the more advanced web master, but information is freely available online should you be interested.

Conclusions

Web hosting can be a very difficult decision with the many thousands of hosting companies out there. It is critical to find a plan that fits your needs and to have a good hosting company. I hope this article was useful in making your decision about which company to host with. Happy Hosting!
