You do not need software to make a website, though it does come in handy if you don't want to learn HTML/XHTML, JavaScript, and CSS. You can learn these three main languages, but it will take time and practice to make a good website. There are many websites out there that let you create a free "website" under a subdomain, such as mycoolsite.wordpress.com. Do a web search for "free website" and you'll find plenty of websites to try. Many of these offer paid upgrades such as you own domain (mycoolsite.com) or more advanced layouts.

The purpose of an ammeter is to sense and display the magnitude of the current

flowing through it. When connected in series with a branch of an electrical circuit,

the meter displays the magnitude (and direction) of the current in that path ... which

you can't otherwise tell just by looking at the circuit.

A C program is basically a collection of functions that are supported by the C library.we can continuously add our own functions to C library.with the availibility of a large number of functions, the programming task becomes simple......

Depending on what test you are talking about...

Hardness can be tested by a device that divots the metal with a calibrated point and measures the force required to make a certain depth divot. Also it can be roughly tested by a set of files that have varying hardness. If the file cuts the steel, its harder than the steel.

Structure testing (checking for cracks) can be done by a process called "Magnaflux" which creates a magnetic field in the piece, and filings are sprinkled on it. The filings will indicate the place where the crack is, because the crack makes opposing poles of magnetism in the piece. Another way is called "Dye Penetrant" in which a fluorescent dye is introduced to the surface of the metal and allowed to penetrate the cracks. The rest is washed off with a solvent, which can't remove the dye in the cracks, which show up under black light.

There are literally thousands of tests that can be carried out on a piece of steel, so its hard to answer this generic question, but those are the two most common practical tests I can think of.

Probably one or two of these guys (you actually need at least two people!):

1. Bob Taylor, one of the original creators of the concept in 1962-1968. He had some sort of internet system between three offices.

Or

2. Lawrence G. Roberts, born 1937 in Connecticut, and who received the Draper Prize in 2001 "for the development of the Internet"

3. Leonard Kleinrock,

4. Robert Kahn,

5. Vinton Cerf.

These last four worked together and developed the 'internet concept' between themselves.

i.e. Larry Roberts and his team created the ARPANet, which was the first significant implementation of Leonard Kleinrock's theories on packet switching, a fundamental feature of (a) the modern internet and (b) ARPANet, the first large network form of the internet.

The Advanced Research Projects Agency Network (ARPANET) developed by ARPA of the U.S. Department of Defense was the world's first operational packet switching network, and the progenitor of the global Internet. During the 1950s, several communications researchers realized that there was a need to allow general communication between users of various computers and communications networks. This led to research into decentralized networks, queuing theory, and packet switching. The subsequent creation of ARPANET in the United States in turn catalyzed a wave of technical developments that made it the basis for the development of the Internet. The first TCP/IP wide area network was operational in 1984 when the United States' National Science Foundation (NSF) constructed a university network backbone that would later become the NSFNet. It was then followed by the opening of the network to commercial interests in 1995. Important separate networks that have successfully entered the Internet include Usenet, Bitnet and the various commercial and educational X.25 networks such as Compuserve and JANET. The collective network gained a public face in the 1990s. In August 1991 CERN in Switzerland publicized the new World Wide Web project, two years after Tim Berners-Lee had begun creating HTML, HTTP and the first few web pages at CERN in Switzerland. In 1993 the Mosaic web browser version 1.0 was released, and by late 1994 there was growing public interest in the previously academic/technical Internet. By 1996 the word "Internet" was common public currency, but it referred almost entirely to the World Wide Web. Meanwhile, over the course of the decade, the Internet successfully accommodated the majority of previously existing public computer networks (although some networks such as FidoNet have remained separate). This growth is often attributed to the lack of central administration, which allows organic growth of the network, as well as the non-proprietary nature of the Internet protocols, which encourages vendor interoperability and prevents any one company from exerting too much control over the network. The IEEE has assigned the 802.1 label to the internetworking among 802 LANs, MANs and other wide area networks, now known as the Internet.

you just have to make a circuit and keep it open.. by not joining the switch wires now when the wires or any other conducting material will get dipped in water the alarm. light, or any other form of signal will be seen..as the circuit will be completed

for creating objects use the new operator along with a call to the constructor. for ex Triangle t = new Triangle(); In this statement the new operator creates a triangle object and the constructor is called which initializes the object and then new returns a reference of the object which is stored in the reference var "t" of type Triangle.

Often more than not the term, "hacker" is used to describe someone that uses computers to break computers or deploy attacks on computer systems. The correct term is "cracker".

A hacker is a person that always asks themselves how something works and then figures it out.

To become a hacker you have to find a project where technology does not exist to make things work the way you want them to then use your smarts to find an answer.

Hacker = Inventor of things on top of things already invented.

or else you can say a solutionfinder for silly solutions t

Technically, the intensity of the electromagnetic fields radiated from electrical transmission lines becomes smaller as the distance from the cable increases, but it never reaches zero. Despite many studies made on the effects of magnetic fields, there is no definitive guide as to what harmful effects high voltage fields have on humans or other living things. The level of risk in being exposed to these fields cannot be categorically stated.

Multiprogramming is the rapid switching of the CPU between multiple processes in memory. It is done only when the currently running process requests I/O, or terminates. It was commonly used to keep the CPU busy while one or more processes are doing I/O. It is now mostly

superceded by multitasking, in which processes also lose the CPU when their time quantum expires.

Multiprogramming makes efficient use of the CPU by overlapping the demands for the CPU and its I/O devices from various users. It attempts to increase CPU utilization by always having something for the CPU to execute.

The prime reason for multiprogramming is to give the CPU something to do while waiting for I/O to complete. If there is no DMA, the CPU is fully occupied doing I/O, so there is nothing to be gained (at least in terms of CPU utilization) by multiprogramming.

RMI simply offers remote access to an object running in another process. But EJB offers far more services than RMI. EJB leverages this remote-object feature of RMI, but also provides other services such as persistence, transaction management, security, and resource management. The EJB server provides all of these complex services which allows EJB developers to worry about business logic instead. For a complete understanding of EJB i suggest Http://edocs.bea.com/wle/rmi/sampejb.htm

Hackers search computers and/or networks for weaknesses. Hackers that exploit these weaknesses are called Black Hats. The ones who try to fix this weaknesses are called White Hats. Grey Hats are both, usually they're White Hat Hackers by day, and Black Hats by night.

When you say holdhold supply of 230volts, you are referring to the RMS value, not the peak value.

A computer is a person or a machine that performs computations. An accountant is a computer (human computer). A slide-rule is a computer (an analog computer). A smart phone is a computer (digital computer).

In symmetrical components, there are three types of impedances - positive sequence (balanced), negative sequence (unbalanced), and zero sequence (ground).

In a transformer, positive and negative are equal. Ground impedance is determined by the (same factors as the) positive sequence and is based on the flux paths available through the transformer core that can induce ground current.
