joomla for beginners

 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.

 

 What IS (CMS) : Content Management System

 


How Joomla! Works

A CMS is a fair bit more complicated than a simple web server, but you will need to
know only the basics to use Joomla effectively. If you understand the general process
that Joomla uses to retrieve content, format it, and return it to the requesting web
browser, you will be able to see how you can configure the Joomla system to present
content in a manner that best suits your needs.
Figure 1-3 presents a block diagram of a simple web server. Interaction begins when
a web browser requests a page of the web server. The web server retrieves the HTML code
from the requested static HTML file (e.g., http://www.example.com/index.html) and returns
it to the browser. The HTML file is called a static web page because the page returned to
the browser is exactly the content contained in the file stored on the server—nothing
more, nothing less. That’s about as simple as it gets.


Joomla! Benefits

With numerous CMS programs available, it’s interesting to note that Joomla alone has
been embraced by a wide spectrum of individuals, corporations, nonprofit organizations,
boutique businesses, and public organizations.
One reason for Joomla’s wide adoption is its ease of use. If you have any experience
with web site construction or CMS design, you can use Joomla once and understand why
people and businesses have adopted it in such large numbers.
Joomla’s ease of use is matched only by its built-in professional features. In addition
to Joomla’s robust native feature set, over 200 free and commercial plug-ins are available
to use with it. This vast array of extensions makes it possible to deploy a Joomla system
that can do almost anything you need, from chat rooms, to online auctions, to classified
ads, to inventory management.
Despite the gold-medal capabilities of the system, however, I think the primary
reason Joomla is so popular is the award-winning user interface aesthetics the application
offers to even the most novice users. The professionally designed user interface
templates, both those included with the default installation and those available from
the large third-party market, can instantly make almost any web site a “sight to
behold.” Gone are the days when a web site required a dedicated professional web
designer to look immaculate. Joomla allows the most humble blog site to stand toe to
toe with a multimillion-dollar web site without blinking. That means a professional
web presence is available to site creators with no graphic arts experience. The aesthetics
of a Joomla site are unparalleled by any other system.
Further, many CMS systems nearly require an advanced degree to set up and maintain.
Joomla, in contrast, enables you to perform all maintenance tasks through a simple
and elegant administration screen (see Figure 1-2). Since Joomla administration is web
based, a Joomla site can be managed from wherever you happen to be—even if you’re
resting comfortably on a beach in Maui with a piña colada in one hand and laptop with
aWi-Fi connection in the other.
In the sections that follow, you’ll be introduced to various Joomla features and learn,
in a nutshell, how the application works.

Sir Arthur C. Clarke's Predictions

2009 The first quantum generators (tapping space energy) are developed. Available in portable and household units, from a few kilowatts upwards, they can produce electricity indefinitely. Central power stations close down: the age of pylons ends.
Electronic monitoring virtually phases out professional criminals.

2011 Largest living animal filmed: a 76-metre octopus in the Mariana Trench. By coincidence, even larger creatures are then discovered when the first robot probes drill through the ice of Europa.

2012 Aerospace-planes enter commercial service.

2013 Prince Harry becomes the first member of the British royal family to fly in space.

2014 Construction of Hilton Orbiter Hotel begins by converting the giant shuttle tanks previously allowed to fall back to Earth.

2015 An inevitable by-product of the quantum generator is complete control of matter at the atomic level. Within a few years, because they are more useful, lead and copper cost twice as much as gold.

2016 Existing currencies are abolished. The "mega-watt-hour" becomes the universal unit of exchange.

2017 On his hundred birthday, December 16, Sir Arthur C. Clarke is one of the first guests in the Hilton Orbiter.

2019 A major meteor impact occurs on the north polar ice cap. The resulting tsunamis cause considerable damage along the coasts of Greeland and Canada. The long-discussed "Project Spaceguard," to identify and deflect potentially dangerous comets or asteroids, is finally activated.

2020 Artificial Intelligence reaches human level. From now on there are two intelligent species on Earth.

2021 The first humans land on Mars.

2023 Dinosaur facsimiles are cloned from computer-generated DNA.

2024 Infrared signals are detected coming from the centre of the Galaxy, obviously the product of a technologically
advanced civilisation. All attempts to decipher them fail.


2025 Neurological research finally leads to an understanding of all the senses, and direct input becomes possible, bypassing ears, eyes, skin, etc. The result is the metal "Braincap." Anyone wearing this close-fitting helmet can enter a whole universe of experience, real or imaginary.
The Braincap is a boon to doctors, who can now experience their patients' symptoms (suitable attenuated). It also revolutionises the legal profession, as deliberate lying is now impossible.

2040 The "Universal Replicator," based on nanotechnology, is perfected: any object, however complex, can be created - given the necessary raw materials. Diamonds or gourmet meals can, literally, be made from dirt.
As a result, agriculture and industry are phased out - along with work. There is an explosion in the arts, entertainment and education. Hunter-gathere societies are deliberately recreated, with huge areas of the planet allowed to revert to their natural state.

2045 The totally self-contained mobile home (envisaged almost a century ago by Buckminster Fuller) is perfected. Any additional carbon needed from food synthesis is obtained by extracting carbon dioxide from the atmosphere.

2050 Bored in this era, millions decide to use cryonic suspension to emigrate into the future in search of adventure.

2057 On October 4, the centenary of Sputnik 1, the dawn of the space age is celebrated by humans on Earth, the Moon, Mars, Europa, Ganymede and Titan, and in orbit around Venus, Neptune and Pluto.

2061 Halley's Comet returns - first landing by humans, And the sensational discovery of both dormant and active life forms vindicates Wickramasinghe and Hoyle's century-old hypothesis that life exists through space.

2090 Burning of fossil fuels is resumed to replace carbon dioxide "mined" from the air and to try to postpone the next Ice Age by promoting global warming.

2095 The development of a "Space Drive" - a propulsion system reacting against the structure of space-time - makes the rocket obsolete and permits velocities close to that of light. Human explorers set off to nearby star systems.

2100 History begins...
