HTML TAGS:

For learning HTML following heading very important because these are basic information of HTML. Therefore read carefully and understand every part of this chapter.......

HTML TAGS:


    Tags contain elements which provide instructions for how information will be processed or displayed. There are both starter tags <TAG> and end tags </TAGS>

Element:

    A basic unit of an HTML document. The name of the element is given in the name of the tag, and specifies the meaning associated with a block of text. Some elements are empty since they don't effect a block of text. Elements that have contents are also called containers, i.e., they contain attributes.
    • Example: the <HR> tag contains the Horizontal Ruler element. It is an empty element in that it has no attribute.

    Attribute:

      Defines a special property of an HTML element.
      • Example: <IMG SRC="image.gif"> means that the element IMG has an attribute SRC, which specifies the name of the image file, which is assigned the value "image.gif".

      Delimiters: <, >, /

        Delimiters surround the tag and inform the parser that it should read the enclosed information as an HTML element.

      HTML Structure

      HTML is a structured hierarchical language that requires you to follow its rules if you wish your documents to appear correctly. For example, certain elements and tags are required to fit within other elements and tags and will not work unless they are properly placed.




      COMPUTER PROGRAMMING LANGUAGE

      COMPUTER PROGRAMMING LANGUAGE

      programming language is a formal computer language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms.
      The earliest known programmable machine preceded the invention of the digital computer and is the automatic flute player described in the 9th century by the brothers Musa in Baghdad, "during the Islamic Golden Age". From the early 1800s, "programs" were used to direct the behavior of machines such as Jacquard looms and player pianos. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. Many programming languages require computation to be specified in an imperative form (i.e., as a sequence of operations to perform), while other languages use other forms of program specification such as the declarative form (i.e. the desired result is specified, not how to achieve it).The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.
