creat html

1.3 STEPS FOR CREATING A SIMPLE HTML PROGRAM

Go to Start -> Programs->Accessories->Notepad.
Begin with a document type tag and an <HTML> opening tag. Enter the following line in your doc.
<HTML>
Indicate that you are beginning the head element of document by issuing the <HEAD> opening tag. If a <HEAD> element is included, it must appear within an <HTML> element. The following line should appear next in your document:
<HEAD>
The <TITLE> element is used to indicate the title of an HTML document. <TITLE> tags are placed with in the head component of a document and the title is placed between the opening and closing <TITLE> tags. Add this <TITLE> element to your document.
<TITLE>My First Page</TITLE>
To end the head area issue a <HEAD> closing tag.

</HEAD>

Thus the <HEAD> element is nested within the <HTML> element.
At this point the body of the document is developed. A <BODY> opening tag indicates that this point has been reached. Enter the following line.
<BODY>

In this case, the body of document contains a simple text statement for now, add the following statement in your file:

Hello World !

7. A </BODY> closing tag marks the end of <BODY> element. Similar to the HAED element, the <BODY> element is also completely nested within the <HTML> element. To end the <BODY> element, issue the closing tag in your document.

</BODY>

8. Finally, terminate the <HTML> tag with </HTML> as shown below :

Basic html

The Web pages or materials in the form of hypermedia documents accessed through the Internet, cab is located anywhere in the world.

No matter where they are originated, most of the web documents are created using Hypertext Markup Language (HTML). HTML is powerful authoring language and found in different versions like HTML 4.2, HTML 4.0, HTML 3.2, HTML 3.0 and HTML 2.

HTML element can be used to define document structure & format, HTML element is the inclusive region defined by either a single tag or a pair of tags. A tags is a string in the language surrounded by a less than (<) and a greater than (>) sign. A opening tag does not begin with a slash (/). An ending or closing tag is a string that begins with a slash (/).

HTML documents format textual information with embedded markup tags that provide style and structure information. Whole document in HTML is surrounded by <HTML> and </HTML>.

Output devices

Output device

An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) to the outside world.

In computing, input/output, or I/O, refers to the communication between an information processing system (such as a computer), and the outside world. Inputs are the signals or data sent to the system, and outputs are the signals or data sent by the system to the outside.

Video monitor

A video monitor also called a broadcast monitor, broadcast reference monitor or just reference monitor, is a device similar to a television, used to monitor the output of a video-generating device, such as a media payout server, IRD, video camera, VCR, or DVD player. It may or may not have audio monitoring capability. Unlike a television, a video monitor has no tuner and, as such, is unable independently to tune into an over-the-air broadcast. One common use of video monitors is in Television stations and in outside broadcast vehicles, where broadcast engineers use them for confidence checking of signals throughout the system. Video monitors are used extensively in the security industry with Closed-circuit television cameras and recording devices.

Speaker

Computer speakers, or multimedia speakers, are speakers external to a computer that disable the lower fidelity built-in speaker. They often have a low-power internal amplifier. The standard audio connection is a 3.5mm (1/8 inch) stereo jack plug often color-coded lime green (following the PC 99 standard) for computer sound cards. A plug and socket for a two-wire (signal and ground) coaxial cable that is widely used to connect analog audio and video components. Also called a "phono connector," rows of prong is 1/8" thick by 5/16" long. A few use an RCA connector for input. There are alsoUSB speakers which are powered from the 5 volts at 200 milliamps provided by the USB port, allowing about half a watt of output power.

Computer speakers range widely in quality and in price. The computer speakers typically packaged with computer systems are small plastic boxes with mediocre sound quality. Some of the slightly better computer speakers have equalization features such as bass and treble controls, improving their sound quality somewhat.

The internal amplifiers require an external power source, known as a 'wall-wart'. More sophisticated computer speakers may have a 'subwoofer' unit, to enhance bass output, and these units usually include the power amplifiers both for the bass speaker, and the small 'satellite' speakers.

Some computer displays have rather basic speaker’s built-in. Laptops come with integrated speakers. Unfortunately the tight restriction on space inevitable in laptops means these speakers unavoidably produce low-quality sound.

INPUT DEVICE

Interactive voice recognition system

Interactive Voice Response (IVR) is a technology that allows a computer to detect voice and dual-tone multi-frequency signaling (DTMF) keypad inputs. IVR technology is used extensively in telecommunication, but is also being introduced into automobile systems for hands-free operation. Current deployment in automobiles revolves around satellite navigation, audio and mobile phone systems. In telecommunications, IVR allows customers to access a company’s database via a telephone keypad or by speech recognition, after which they can service their own inquiries by following the instructions. IVR systems can respond with pre-recorded or dynamically generated audio to further direct users on how to proceed. IVR systems can be used to control almost any function where the interface can be broken down into a series of simple menu choices. In telecommunications applications, such as customer support lines, IVR systems generally scale well to handle large call volumes.

It has become common in industries that have recently entered the telecommunications industry to refer to an Automated Attendant as an IVR. The terms Automated Attendant and IVR are distinct and mean different things to traditional telecommunications professionals, whereas emerging telephony and VoIP professionals often use the term IVR as a catch-all to signify any kind of telephony menu, even a basic automated attendant. The term VRU, for Voice Response Unit, is sometimes used as well.^[1]
