Volcanoes are some of nature's most awe-inspiring displays, with everything from exploding mountaintops to rivers of lava. Learn how all the different types of volcanoes work.
­­


Whenever there is a major volcanic eruption in the world, you'll­ see a slew of newspaper articles and nightly news stories covering the catastrophe, all stressing a familiar set of words -- violent, raging, awesome. When faced with a spewing volcano, people today share many of the same feelings volcano-observers have had throughout human history: We are in awe of the destructive power of nature, and we are unsettled by the thought that a peaceful mountain can suddenly become an unstoppable destructive force!
While scientists have cleared up much of the mystery surrounding volcanoes, our knowledge has not made volcanoes any less amazing. In this article, we'll take a look­ at the powerful, violent forces that create eruptions, and see how these eruptions build volcanic structures like islands.
­When people think of volcanoes, the first image that comes to mind is probably a tall, conical mountain with orange lava spewing out the top. There are certainly many volcanoes of this type. But the term volcano actually describes a much wider range of geological phenomena.
Generally speaking, a volcano is any place on a planet where some material from the inside of the planet makes its way through to the planet's surface. One way is "material spewing from the top of a mountain", but there are other forms as well. Check out the next page to fi­nd out more about magma (that "material spewing") and plate tectonics!

An increasing number of IT professionals have been finding it difficult to handle emotional stress, according to experts. An ‘occupational hazard,' the stress related to work needs to be addressed without delay, they emphasise.

“Coping with stress and striving for mental health welfare should be a matter of concern for all and not treated simply as a lifestyle problem of the ‘IT phenomenon',” says Nithya Chandrasekaran, a consultant physician for many IT companies in the city.

Regular occupational problems such as wrist problems due to constant handling of the mouse, slip disc and eye fatigue are common now, but handling stress that arises owing to fear of losing job or to cope with the increasing competition, affects the employee's performance, eventually, taking a major toll on his health, doctors explain.

Computer Server

Server A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet.

Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server. For example, a Web server may run Apache HTTP Server or Microsoft IIS, which both provide access to websites over the Internet. A mail server may run a program like Exim or iMail, which provides SMTP services for sending and receiving email. A file server might use Samba or the operating system's built-in file sharing services to share files over a network.

While server software is specific to the type of server, the hardware is not as important. In fact, a regular desktop computers can be turned into a server by adding the appropriate software. For example, a computer connected to a home network can be designated as a file server, print server, or …
