1.managed module:A managed module is a standard 32-bit Microsoft Windows portable executable (PE32) file or a standard 64-bit Windows portable executable (PE32+) file that requires the CLR to execute.

2.Metadata:Every managed module contains metadata tables. There are two main types of tables: tables that describe the types and members defined in your source code and tables that describe the types and members referenced by your source code.

3.assembly:First, an assembly is a logical grouping of one or more modules or resource files. Second, an assembly is the smallest unit of reuse,security, and versioning.

4.manifest:The manifest is simply another set of metadata tables. These tables describe the files that make up the assembly, the publicly exported types implemented by the files in the assembly, and the resource or data files that are associated with the assembly.

primary thread calls a method defined inside MSCorEE.dll. This method initializes the CLR,
loads the EXE assembly, and then calls its entry point method (Main). At this point, the managed
application is up and running.

GEM IN THE ROUGH
Divs and Spans

Chapter 1 introduced you to <div> and <span>, two generic HTML tags that you can bend to your CSS wishes. When there's no HTML tag that exactly delineates where you want to put a class or ID style you've created, use a <div> or <span> to fill in the gaps.

The div tag identifies a logical division of the page like a banner, navigation bar, sidebar, or footer. You can also use it to surround any element that takes up a chunk of the page, including headings, bulleted lists, or paragraphs. (Programmer types call these block-level elements because they form a complete "block" of content, with line breaks before and after them.) The <div> tag works just like a paragraph tag: type the opening <div>, add some text, a photo, or some other content inside it, and then end it with the closing </div>.

The div tag has the unique ability to contain several block-level elements, making it a great way to group tags that are logically related such as the logo and navigation bar in a page's banner, or a series of news stories that compose a sidebar. Once grouped in this way, you can apply specific formatting to just the tags inside the particular div, or move the entire div-tagged chunk of content into a particular area, such as the right side of the browser window (CSS can help you control the visual layout of your pages in this manner as described in Part 3 of this book).

For example, say you added a photo to a Web page; the photo also has a caption that accompanies it. You could wrap a <div> tag (with a class applied to it) around the photo and the caption to group both elements together:

	<div class="photo">

        <img src="holidays.jpg"

        alt="Penguins getting frisky"/>

        <p>Mom, dad and me on our yearly trip

        to Antarctica.</p>

        </div>

Depending on what you put in the declaration block, the .photo class can add a decorative border, background color, and so on, to both photo and caption. Part 3 of this book shows you even more powerful ways to use <div> tagsincluding nested divs.

A <span> tag, on the other hand, lets you apply a class or ID style to just part of a tag. You can place <span> tags around individual words and phrases (often called inline elements) within paragraphs to format them independently. Here, a class called .companyName styles the inline elements "CosmoFarmer.com," "Disney," and "ESPN":

	<p>Welcome to <span class="companyName">

        CosmoFarmer.com</span>, the parent

        company of such well-known corporations

        as <span class="companyName">Disney

        </span> and <span class="companyName">

        ESPN</span>…well, not really.</p>









2.When deciding whether to use a class or an ID, follow these rules of thumb:

To use a style several times on a page, you must use classes.
For example, when you have more than one photo on your page, use a class
selector to apply stylinglike a borderto each of them.

Use IDs to identify sections that occur only once per page.
CSS-based layouts often rely on ID selectors to identify the unique parts of a
Web page, like a sidebar or footer. Part 3 shows you how to use this
technique.
Consider using an ID selector to sidestep style conflicts,

since Web browsers give ID selectors priority over class selectors. For example, when a browser encounters
two styles that apply to the same tag but specify different background colorsthe
ID's background color wins.

3.JavaScript programming utilizes ID selectors to locate and manipulate parts of a page. For example, programmers often apply an ID to a form element like a text box for collecting a visitor's name. The ID lets JavaScript access that form element and work its magiclike making sure the field isn't empty when the visitor clicks Submit.
