Elephants, facts about elephants
Elephants are wonderful animals! They are the largest mammals in the world that live on land. There are two kinds of elephants; African and Asian. Asian elephants have smaller ears and shorter tusks than African elephants.
The African elephant is bigger and taller than the Asian elephant. The largest living mammal on earth is none other than the elephant. With the heaviest mammal weighing around 12000 kgs you can imagine how huge this living giant can be. Its one leg could probably crumble an entire tree or a couple of them.
google_protectAndRun("render_ads.js::google_render_ad", google_handleError, google_render_ad);
The gestation period of this mammal is 22 months, the maximum of any mammal in the animal kingdom. And baby calf weighs around 120 kgs. Heavy baby! But as heavy as they may seem they are vulnerable to being hunted by lions who gulp in baby elephants and the weaklings in the herd. As otherwise no animal dare come into close proximity of the elephant, anyway who wants to have their bones crushed.Other than animals, humans are more of a threat to this breed. As they are poached and hunted for their tusks or a wide scale. Over a lakh of elephants were killed earlier on an annual average. It is only recently in India that laws against poaching have gotten stringent making it difficult to poach them, not impossible. The practice continues although much diminished in Africa. The tusks of the elephant are of pure ivory that is a great material for crafting. To the adult mammal it keeps growing on an average of 7 inches in a year. Summing to sometimes 10 feet in an African elephant and weighing around 90 kgs. Well now we know why they are so healthy, all to carry their own weight around.
The tusks are used to dig water, carry logs of wood for shelter or to clear the trees as these guys make their way through the jungle. An interesting fact about the tusk is like humans who are right and left handed, elephants are right and left tusked. The dominant tusk is a little shorter and rounded as against the other tusk. So you have a right tusked elephant and left tusked elephant. There are many nuances of the elephant that when put light upon bring awe and awareness to the common man.
Do elephants live together?
Elephants live in families. Several families live together in a "herd." The leader of the herd is usually the oldest female elephant. She is called the "matriarch." All the babies and other females follow her.
A young male elephant stays with the herd until he is fourteen or fifteen years old. Then, he goes out on his own. The young male will try to find a female elephant for a companion.
What do elephants eat?
Elephants are plant-eaters. Because they are such big animals, they need to eat large amounts of leaves, grass and tree bark. They spend as much as twenty hours a day eating! A full-grown African elephant can weigh more than 10,000 pounds!
Teeth and Tusks
Elephants have four teeth and two "tusks." The tusks are the long horn-like parts that come out the sides of their mouths. These tusks grow about seven inches a year, and can get up to twenty feet long! The tusks are made of ivory, which is very valuable.
The elephants four teeth are molars. About every four years, the molars fall out and are replaced by new ones. The molars of an adult elephant can be up to ten inches long!

Ears and Trunks
The ears of a full-grown African elephant are about five to six feet long and four feet wide. They sometimes flap their ears to cool themselves.
An elephant's trunk is actually part nose and part upper lip. Elephants can breathe through their trunks. They can also smell and pick up things with it. They can use it to put food into their mouths, and can even spray water with it! The trunk is used to feel things, too!

How do elephants cool themselves?
When it is hot, elephants like to get into water and mud. They also use their trunks to spray water and dust on their bodies. Wrinkles on their skin trap the water and help with the cooling.

How do elephants talk?
Elephants talk to each other by making sounds called "tummy rumbles." They also make a "trumpeting" sound to call to each other.
How long do elephants live?
Elephants can live as long as eighty years!
You can see elephants in zoos. Many zoos work hard to keep the elephants happy, by providing them with the kind of habitat they would have if they were out in the wild.
A great number of elephants have been shot so people could get their ivory tusks. People all over the world have tried to stop this cruel killing of elephants. Now, very few are killed for their ivory, and there are laws to protect the elephants.
In the past, many elephants were trained to perform tricks for circuses. They were often treated in a cruel manner. Today, there are laws to protect elephants and to ensure they are well-cared

important information

A cat can run about 20 kilometres per hour (12 miles per hour) when it grows up. This one is going nowhere today - it is too lazy !.


A cheetah can run 76 kilometres per hour (46 miles per hour) - that's really fast! The fastest human beings runs only about 30 kilometres per hour (18 miles per hour).



Bears whose brown fur is tipped with lighter-colored hairs are called grizzly bears . The smallest species of bears is called sun or Malayan bears. Male bears are called boars. Bears are native to the continents of North America, Asia, Europe, and South America. Alaskan brown bears, world's largest meat-eating animals that live on land, can weigh as much as 1,700 pounds (771 kilograms



There are more than 50 different kinds of kangaroos. Kangaroos are native of Australia. A group of kangaroos is called a mob. Young kangaroos are called joeys.



How do reindeers survive in the extreme cold? Most animals don’t eat moss. It’s hard to digest, and it has little nutritional value. But reindeer fill up with lots of moss. Why? The moss contains a special chemical that helps reindeer keep their body fluids warm. When the reindeer make their yearly journey across the icy Arctic region, the chemical keeps them from freezing—much as antifreeze keeps a car from freezing up in winter


The largest frog in the world is called Goliath frog. Frogs start their lives as 'eggs' often laid in or near fresh water. Frogs live on all continents except Antarctica. Frogs belong to a group of animals called amphibians.


Some scientists believe that the earth began billions of years ago as a huge ball of swirling dust and gases. If you dig in your backyard, don’t worry about running into the earth’s core. You’d have to dig a hole 4,000 miles (6,437 kilometers) deep!



The first kind of PENCIL was a bunch of GRAPHITE sticks held together by string. Then someone decided it would be better to push the graphite into the inside of a hollow wooden stick.
JOSEPH RECHENDORFER was the first person to think of putting a piece of rubber onto the top of a pencil which makes it real easy to rub out mistakes.
Did you know that the average lead pencil can draw a line that is almost 35 miles long or you can write almost 50,000 words in English with just one pencil? Amazing fact! Now imagine an eraser that could match it !!!



Did you know the first bicycle that was made in 1817 by Baron von Drais didn't have any pedals? People walked it along


The first metal bicycle was called the High-Wheel or Penny Farthing. People had a hard time keeping their balance on this type of bicycle


Did you know the first toy balloon, made of vulcanized rubber, was thought of by someone in the J.G.Ingram company in London, England in 1847.


Did you know?
The Industrial Revolution in Europe first saw the beginning of air pollution, which gradually became a major global problem.
The major air-polluting industries are iron, steel and, cement.
Of the 35-40 million tonnes of flyash generated annually by thermal power plants in India, only 2-3 percent is productively utilized.
The worst industrial disaster in India, occurred in 1984 in Bhopal the capital of Madhya Pradesh. A deadly chemical, methly isocyanate leaked out of the Union Carbide factory killing more than 2500 and leaving thousands sick. In fact the effects of this gas tragedy is being felt even today.
Every year some 50million cars are added to the world’s roads. Car making is now the largest manufacturing industry in the world.
In India the number of motorized vehicles have increased from 0.2 million in 1947 to 36.3 million in 1997.
The number of registered vehicles in Delhi is more than the sum total of registered vehicles in Mumbai, Calcutta, and Chennai.
Major contributor to Delhi's air pollution are vehicles.
Nearly three-fourths of India's population, which is rural, bears 84% of the burden of exposure to air pollution.
Growing population, poverty, and inadequate access to clean fuels in rural areas have perpetuated the use of biomass, thereby condemning more than 90% of rural households and more than 35% of urban hoseholds to high levels of indoor air pollution.
One of the most important measure to counter pollution is planting trees. With neem and peepal being the largest emitters of oxygen, planting them in the gardens purifies the surrounding air and helps in maintaining hygienic conditions. While champa, mogra and chameli have better chances of surviving pollution in summer, bulbous varieties do better in winter. Courtesy

Dosti Shayari

Thu 25 Jun 2009
Jab bhi in hoton par naam tera aaya,MIt gaye saare gum diwana dil muskuraya.Saanse ruk jaati humari logon ne itna rulaya,aap se seene se lagkar is dil ko chain aaya.Bhool gaye chubhte gum aap ne itna hasaya,Bohot khushnaseeb hai hum jo aapko is zindgi me paaya.

LOVE POEM

Apno se juda kar deti hai,

Aakhon mein paani bhar deti hai,

Kitni shikayat hai zindgi se.

Phir bhi iska aitbaar hai,

Phir bhi iska intzaar hai,

Humko mohabbat hai zindgi se.

Kabhi khushiyon ka mela lagta hai,

Kabhi har koi akela lagta hai.

Kabhi humpe karam pharmati hai,

Kabhi humse nazar churati hai.

Palkon se isko chakhte hain,

Isey pass hi apne rakhte hain,

Itni nazakat hai zindgi se,

Humko mohabbat hai zindgi se.

Humko adaayein dikhati hai ye,

Jeena bhi humko sikhati hai ye.

Kabhi paas hai to kabhi door hai,

Ye zindgi bhi badi mashhoor hai.

Kabhi karti hai aankh micholi,

kabhi sajaye sapno ki doli,

Itni shararat hai zindgi se.

Humko mohabbat hai zindgi se.

Door ye ho to ghum hota hai,

Pass ho to iska karam hota hai.

Khud apni marzi se chalti hai,

Suraj ki tarah se ye dhalti hai.

Isey jab bhi hum dekhte hain,

Mann hi mann ye sochte hain,

Kitni hifazat hai zindgi se.

Humko mohabbat hai zindgi se.

Aansu bhi ho to pee lete hain,

Pal do pal khushi se jee lete hain.

Har pal humko nahi hai roka,

Thoda humko bhi deti mouka.

Zindgi gujar jaaye taqraar mein,

Chahe gujar jaaye ye pyaar mein,

Itni izazat hai zindgi se.

Humko mohabbat hai zindgi se.
With Warm Regards

what is software













































What is Software?
Software is the general term for information that's recorded onto some kind of medium. For example, when you go to the video store and rent or buy a tape or DVD, what you're really getting is the software that's stored on that tape or disk. Your VCR or DVD player are hardware devices that are capable of reading the software from a tape or disk and projecting it onto your TV screen, in the form of a movie.
Your computer is a hardware device that reads software too. Most of the software on your computer comes in the form of programs. A program consists of "instructions" that tell the computer what to do, how to behave. Just as there are thousands of albums you can buy on CD for your stereo, and thousands of movies you can buy to play on your VCR or DVD player, there are thousands of programs that you can buy to run on your computer.
When you buy a computer, you don't automatically get every program produced by every software company in the world. You usually get some programs. For example, when you buy a computer it will probably have an operating system (like Windows XP) already installed on it.
If you do purchase a specific program, it would be to perform some specific task. For example, you might use a graphics program to touch up photos, or you might use a word processing program to write text. You're using your Web browser program right now to read this text (assuming you're not reading a printed copy on paper). Just as there are umpteen different brands of toothpaste, there are umpteen different brands of word processing programs, graphics programs, and Web browsers.














































For example, all graphics programs are designed to help you work with pictures. But there are many brands of graphics programs out there, including Adobe Photoshop, Jasc Paint Shop Pro. Adobe Illustrator, Arcsoft PhotoStudio, Corel Draw, ULead PhotoImpact, PrintShop Photo, and Macromedia Freehand, just to name a few. As to Web browsers, popular brands include Microsoft Internet Explorer, MSN Explorer, Netscape Navigator, America Online, and a few others.
When you purchase a program, you get the program stored on a CD as in the example shown at left. You may not have seen any boxes containing software when you bought your computer. That's because the software that came with your computer has been pre-installed onto your computer's hard disk for you. You don't need to use the CD to run a program that's already installed on your computer. You only need to keep the CDs as backups, in case something goes wrong with your hard disk and you need to re-install the programs.
What Programs Do I Have?
Perhaps you're wondering what programs are installed on your computer. Usually when you buy a computer, they tell you what programs you're getting with it. So if you were to go back to the original ad from which you bought your computer, you'd probably find the names of programs you already have listed there. Though there's no need to do that, because every program that's currently installed on your computer is listed in your All Programs menu (assuming you're using Windows XP).
When you first open the Start menu, the left column lists programs you've used the most recently (Figure 1). If your computer is brand new, then the programs listed there will just be some examples.
Figure 1
That little list of program icons and names on the left side of the menu doesn't represent all the programs that are currently installed on your computer. Not by a long shot. The All Programs option on the Start menu provides access to all your installed programs. When you first click on (or just point to) the All Programs option, the All Programs menu that appears (Figure 2) will show icons and name of program groups, as well as some programs.
Figure 2
It's easy to tell the difference between a program and a program group. The program groups all have the same icon, and all have a right-pointing triangle (4) at their right side. When you click on, or point to, a program group, icons and names of programs within that group appear on a submenu. The submenu will contain programs within that group, and perhaps some more program groups. For example, Figure 3 shows the result of clicking on the Accessories program group in the All Programs menu. The submenu that opens contains more program groups, and specific programs you can run.
Figure 3
Your Start menu won't look exactly like the one shown in the figures, because different computers have different programs installed. (Just like different people who own CD players own different CDs).
Running Programs
When you click on the icon for a program, the program opens. Which means the program appears on the screen, so you can use it. Each program will appear in its own program window on the Windows desktop. For example, in Figure 4 the photograph in the background is the Windows desktop. Floating about on top of that desktop are four different program, each in its own separate program window.

Figure 4
Elements of Program Windows
While not two programs are exactly alike, most program windows contain certain similar elements. Stretched across the top of the program window is the title bar, which usually shows the name of the program that's inside the program window. Beneath the title bar is the menu bar, which gives you access to the tools and capabilities of that specific program. Many programs have a toolbar under their menu bar. The toolbar provides quick one-click access to frequently-used commands in the menu bar. The status bar at the bottom of a program provides general information. Figure 5 shows, in animated form, the title bar, menu bar, toolbar, and status bar of several different sample programs.
Figure 5
What's Available?
If you ever want to get an idea of the different types of programs that are available for your Windows XP computer, just go to any large computer store, or even a large office supply store like Staples, and take a look at the computer software. Or, you could even go into a large bookstore and look at the computer books sections. There will probably be a ton of books -- all for different programs like Microsoft Word, Microsoft Excel, WordPerfect, and of course Windows XP.
If you're comfortable using the World Wide Web, you can check our programs that are available by visiting the Windows Catalog Web site at:
http://www.windowscatalog.com/
When you get to the Windows Catalog home page, click on the Software tab near the top of the page. Then click on the various categories of programs at the left side of the page (Figure 6). Each will display a submenu if types of programs within that category. You can click on any subcategory name to view programs within that subcategory. Or you can just click on any category name in that left column.
Figure 6
Keep in mind that there's a huge difference between viewing programs on your own Start menu, and viewing programs at the Windows Product Catalog Web site or a computer store. Programs on your Start menu are already installed on your computer and ready for you to use. Programs in a store or presented on the Windows Catalog Web site are programs you could buy and install on your computer.
Remember, software is to a computer as music is to a CD player, or as a movie is to a VCR. There are thousands of programs available for your PC, and no two people have exactly the same programs on their computers. The programs that are installed on your computer can all be found, and started from, the All Programs menu (or some program group that's accessible from All Programs menu). Windows XP, the topic of this course, is software too.

Networking


1960

AT&T Dataphone
AT&T designed its Dataphone, the first commercial modem, specifically for converting digital computer data to analog signals for transmission across its long distance network. Outside manufacturers incorporated Bell Laboratories´ digital data sets into commercial products. The development of equalization techniques and bandwidth-conserving modulation systems improved transmission efficiency in national and global systems.
1964

Online transaction processing made its debut in IBM´s SABRE reservation system, set up for American Airlines. Using telephone lines, SABRE linked 2,000 terminals in 65 cities to a pair of IBM 7090 computers, delivering data on any flight in less than three seconds.

JOSS configuration
JOSS (Johnniac Open Shop System) conversational time-sharing service began on Rand´s Johnniac. Time-sharing arose, in part, because the length of batch turn-around times impeded the solution of problems. Time sharing aimed to bring the user back into "contact" with the machine for online debugging and program development.
1966

Acoustically coupled modem
John van Geen of the Stanford Research Institute vastly improved the acoustically coupled modem. His receiver reliably detected bits of data despite background noise heard over long-distance phone lines. Inventors developed the acoustically coupled modem to connect computers to the telephone network by means of the standard telephone handset of the day.
1970

Citizens and Southern National Bank in Valdosta, Ga., installed the country´s first automatic teller machine.

ARPANET topology
Computer-to-computer communication expanded when the Department of Defense established four nodes on the ARPANET: the University of California Santa Barbara and UCLA, SRI International, and the University of Utah. Viewed as a comprehensive resource-sharing network, ARPANET´s designers set out with several goals: direct use of distributed hardware services; direct retrieval from remote, one-of-a-kind databases; and the sharing of software subroutines and packages not available on the users´ primary computer due to incompatibility of hardware or languages.
1971

Ray Tomlinson in 2001
The first e-mail is sent. Ray Tomlinson of the research firm Bolt, Beranek and Newman sent the first e-mail when he was supposed to be working on a different project. Tomlinson, who is credited with being the one to decide on the "@" sign for use in e-mail, sent his message over a military network called ARPANET. When asked to describe the contents of the first email, Tomlinson said it was “something like "QWERTYUIOP"”
1972

Wozniak´s "blue box"
Wozniak´s "blue box", Steve Wozniak built his "blue box" a tone generator to make free phone calls. Wozniak sold the boxes in dormitories at the University of California Berkeley where he studied as an undergraduate. "The early boxes had a safety feature — a reed switch inside the housing operated by a magnet taped onto the outside of the box," Wozniak remembered. "If apprehended, you removed the magnet, whereupon it would generate off-frequency tones and be inoperable ... and you tell the police: It´s just a music box."
1973

Ethernet
Robert Metcalfe devised the Ethernet method of network connection at the Xerox Palo Alto Research Center. He wrote: "On May 22, 1973, using my Selectric typewriter ... I wrote ... "Ether Acquisition" ... heavy with handwritten annotations — one of which was "ETHER!" — and with hand-drawn diagrams — one of which showed `boosters´ interconnecting branched cable, telephone, and ratio ethers in what we now call an internet.... If Ethernet was invented in any one memo, by any one person, or on any one day, this was it."Robert M. Metcalfe, "How Ethernet Was Invented", IEEE Annals of the History of Computing, Volume 16, No. 4, Winter 1994, p. 84.
1975

Telenet, the first commercial packet-switching network and civilian equivalent of ARPANET, was born. The brainchild of Larry Roberts, Telenet linked customers in seven cities. Telenet represented the first value-added network, or VAN — so named because of the extras it offered beyond the basic service of linking computers.
1976

The Queen of England sends first her e-mail. Elizabeth II, Queen of the United Kingdom, sends out an e-mail on March 26 from the Royal Signals and Radar Establishment (RSRE) in Malvern as a part of a demonstration of networking technology.
1979

The Shockwave Rider
John Shoch and Jon Hupp at the Xerox Palo Alto Research Center discover the computer "worm," a short program that searches a network for idle processors. Initially designed to provide more efficient use of computers and for testing, the worm had the unintended effect of invading networked computers, creating a security threat.Shoch took the term "worm" from the book "The Shockwave Rider," by John Brunner, in which an omnipotent "tapeworm" program runs loose through a network of computers. Brunner wrote: "No, Mr. Sullivan, we can´t stop it! There´s never been a worm with that tough a head or that long a tail! It´s building itself, don´t you understand? Already it´s passed a billion bits and it´s still growing. It´s the exact inverse of a phage — whatever it takes in, it adds to itself instead of wiping... Yes, sir! I´m quite aware that a worm of that type is theoretically impossible! But the fact stands, he´s done it, and now it´s so goddamn comprehensive that it can´t be killed. Not short of demolishing the net!" (247, Ballantine Books, 1975).

USENET established. USENET was invented as a means for providing mail and file transfers using a communications standard known as UUCP. It was developed as a joint project by Duke University and the University of North Carolina at Chapel Hill by graduate students Tom Truscott, Jim Ellis, and Steve Bellovin. USENET enabled its users to post messages and files that could be accessed and archived. It would go on to become one of the main areas for large-scale interaction for interest groups through the 1990s.

Richard Bartle and Roy Trubshaw circa 1999
The first Multi-User Domain (or Dungeon), MUD1, is goes on-line. Richard Bartle and Roy Trubshaw, two students at the University of Essex, write a program that allows many people to play against each other on-line. MUDs become popular with college students as a means of adventure gaming and for socializing. By 1984, there are more than 100 active MUDs and variants around the world.
1983

The ARPANET splits into the ARPANET and MILNET. Due to the success of the ARPANET as a way for researchers in universities and the military to collaborate, it was split into military (MILNET) and civilian (ARPANET) segments. This was made possible by the adoption of TCP/IP, a networking standard, three years earlier. The ARPANET was renamed the “Internet” in 1995.
1985

The modern Internet gained support when the National Science foundation formed the NSFNET, linking five supercomputer centers at Princeton University, Pittsburgh, University of California at San Diego, University of Illinois at Urbana-Champaign, and Cornell University. Soon, several regional networks developed; eventually, the government reassigned pieces of the ARPANET to the NSFNET. The NSF allowed commercial use of the Internet for the first time in 1991, and in 1995, it decommissioned the backbone, leaving the Internet a self-supporting industry.The NSFNET initially transferred data at 56 kilobits per second, an improvement on the overloaded ARPANET. Traffic continued to increase, though, and in 1987, ARPA awarded Merit Network Inc., IBM, and MCI a contract to expand the Internet by providing access points around the country to a network with a bandwidth of 1.5 megabits per second. In 1992, the network upgraded to T-3 lines, which transmit information at about 45 megabits per second.

Stewart Brand and Larry Brilliant lecturing on the Well, 1999
The Whole Earth 'Lectronic Link (WELL) is founded. Stewart Brand and Larry Brilliant started an on-line Bulletin Board System (BBS) to build a “virtual community” of computer users at low cost. Journalists were given free memberships in the early days, leading to many articles about it and helping it grow to thousands of members around the world.
1988

ARPANET worm
Robert Morris´ worm flooded the ARPANET. Then-23-year-old Morris, the son of a computer security expert for the National Security Agency, sent a nondestructive worm through the Internet, causing problems for about 6,000 of the 60,000 hosts linked to the network. A researcher at Lawrence Livermore National Laboratory in California discovered the worm. "It was like the Sorcerer´s Apprentice," Dennis Maxwell, then a vice president of SRI, told the Sydney (Australia) Sunday Telegraph at the time. Morris was sentenced to three years of probation, 400 hours of community service, and a fine of $10,050.Morris, who said he was motivated by boredom, programmed the worm to reproduce itself and computer files and to filter through all the networked computers. The size of the reproduced files eventually became large enough to fill the computers´ memories, disabling them.
1990

Berners-Lee proposal
The World Wide Web was born when Tim Berners-Lee, a researcher at CERN, the high-energy physics laboratory in Geneva, developed HyperText Markup Language. HTML, as it is commonly known, allowed the Internet to expand into the World Wide Web, using specifications he developed such as URL (Uniform Resource Locator) and HTTP (HyperText Transfer Protocol). A browser, such as Netscape or Microsoft Internet Explorer, follows links and sends a query to a server, allowing a user to view a site.Berners-Lee based the World Wide Web on Enquire, a hypertext system he had developed for himself, with the aim of allowing people to work together by combining their knowledge in a global web of hypertext documents. With this idea in mind, Berners-Lee designed the first World Wide Web server and browser — available to the general public in 1991. Berners-Lee founded the W3 Consortium, which coordinates World Wide Web development.
1993

Screen Capture from Original Mosaic Browser
The Mosaic web browser is released. Mosaic was the first commercial software that allowed graphical access to content on the internet. Designed by Eric Bina and Marc Andreessen at the University of Illinois’s National Center for Supercomputer Applications, Mosaic was originally designed for a Unix system running X-windows. By 1994, Mosaic was available for several other operating systems such as the Mac OS, Windows and AmigaOS.
