What is Dreamweaver CS4?

What is Dreamweaver CS4?
Dreamweaver is a powerful but easy-to-use web site development program that bridges the gap between designer and developer. Although it includes advanced features for developing complex data-driven applications, Dreamweaver’s intuitive interface and extensive libraries let even the novice web designer develop a professional web site quickly and easily.

The latest version, Dreamweaver CS4, includes extensive Cascading Style Sheet (CSS) support and conforms more clearly to the CSS design process by eliminating layers in favor of div tags, which can be controlled through CSS rules, and AP elements (which are equivalent to layers in previous versions). If you’re new to CSS, Dreamweaver includes a large number of predefined CSS layout pages, which make it possible to create professional-looking layouts that conform to the latest in web standards

World Wide Web

World Wide Web
It was not designed as a programming or logic processing plat form. It was originally all about sending specially formatted text files from one computer to another, using web browser to display it to the screen.
Getting html of web page
Telnet www.Domain name 80 port number you screen may go blank for some time before you will see ‘connected’ message type the following command spacing accurately.
GET/HTTP/1.0
Don’t miss the spaces surrounding the first slash. Follow this command with two Enter key. This command asks the remote system to send the default web page at the top of that server’s web hierarchy.
When the client asked for a web page ending with the extension. Cgi, the web server process ran a separate script that generated the content.
This led to Active Server Pages (ASP), a solution that allowed developers to the embed server-side script right in the HTML content, and have it adjust the content before it was sent to the client.

Active Documents

Active Documents
A program or a script that run at the client site is called active documents. For example, suppose we want to run a program that creates animated graphics on the screen or a program that interacts with the user. The program definitely needs to be run at the client site where the animation or interaction takes place.
One way to create an active document is to use Java applets. The browser can directly request the Java applet program in the URL and receive the applet in binary form. The browser can retrieve and run an HTML file that has embedded the address of the applet as a tag.
Java script is also can be used to scripts an active docume

Technologies Involved in Creating Dynamic Documents Using Scripts

Technologies Involved in Creating Dynamic Documents Using Scripts: Hypertext preprocessor (PHP), which uses the perl language; Java Server Pages (JSP); Active Server pages (ASP), which uses Visual Basic, and Cold Fusion, were embeds SDL database queries in the HTML document.
Dynamic documents are sometimes referred to as server-site dynamic documents.

web document

WEB DOCUMENTS
The documents in the www can be grouped into three broad categories: static, dynamic, and active. The category is based on the time at which the contents of the document are determined.
(1) Static documents: are fixed-content documents that are created and stored in a server. The client can get only a copy of the document. (HTML) Hypertext Markup Language is a language for creating web pages. Web page are formatted by a markup language for interpretation by a browser.
Tags (marks)
//Bold
A web page is made up of two parts the head and the body.
/The head contains the title while the body contains the actual contents of a page.
Every HTML tag is a name followed by an optional list of attributes.
Beginning tag or mark

ending tag or mark.

HREF (hyperlink
(2) Dynamic Documents
A dynamic document is created by a web server whenever a browser requests the document. When a request arrives, the web server runs an application program or a script that creates the dynamic document. The server returns the output of the program or script as a response to the browser that requested the document.
Common Gateway Interface (CGI) is a technology that creates and handles dynamic documents. CGI is a set of standards that defines how a dynamic document is written, how data are input to the program, and how the output result is used. CGI is not a new language: instead, it allows programmers to use any of several languages such as C, C++, Bourne shell, C shell, Tel, or perl. The only thing that CGI defines is a set of rules and terms that the programmer must follow.
Scripting Technologies for Dynamic Documents
The problem with CGI technology is the inefficiency that results if part of the dynamic document that is to be created is fixed and not changing from request to request. If we use CGI, the program must create an entire document each time a request is made. The solution is to create a file containing the fixed part of the document using HTML and embed a script, a source code.

domain name

DOMAIN
Domain
Root
Sub domainA domain is a subtree of the domain name space. The name of the domain is the domain name of the node at the top of the subtree. Note that a domain may itself be divided into domains (or subdomains).



Zone is a contiguous part of the entire tree. It a server accepts responsibility for a domain and does not divide the domain into smaller domains, the domain and the zone refer to the same thing.
WWW and HTTP
The WWW project was initiated by CERN (European Laboratory for particle Physics).
Client
Request t
Site/server
Wed page
Response The WWW today is a distributed client/server service, in which a client using a browser can access a service using a server.




A browser is a program that is designed to fetch web documents.
Each browser usually contains of three parts: a controller, client protocol, and interpreters.
The controller receives input from the keyboard or the mouse and uses the client programs to access the document. After the document has been accessed, the controller uses one of the interpreters to display the document pm the screen. The client protocol can be one of the protocols ‘FTP, HTTP etc. The interpreter can be HTML, Java, or Java script, depending on the type of document.
Server always store requested files in a cache in memory; memory is faster to access than disk.
Uniform Resource Locator (URL) is a standard for specifying any kind of information on the internet. The URL defines four things; protocol, host computer, port, and parth.
URL
Protocol: //Host: Port/Path
The protocol is the client/saver program used to retrieve the document eg FTP/HTTP. The host is the computer on which the information is located.
The URL can optionally contain the port number of the server.
Path is the path name of the file where the information is located.
Cookies are used by server to know old client and to restrict access to unauthorized client.
The site that restricts access to registered clients only sends of cookie to the client when the client registers for the first time. For any repeated access, only those clients that send the appropriate cookie are allowed.
Note that the contents of the cookie are never read by the browser or disclosed to the user. It is a cookie made by the server and eaten by the server.

What is webdesigning ?

WED DESIGNING
The client/server programs can be divided into two categories: those that can be directly used by the user, such as e-mail, and those that support other application programs. The Domain Name system (DNS) is a supporting program that is used by other programs such as e-mail.
People prefer to use names instead of numeric addresses. Therefore, we need a system that can map a name to an address vice versa. To identify an entity, TCP/IP protocols use the IP address, which uniquely identifies the connection of a host to the internet.
Name space is a unique name assigned to a machine.
TWO TYPES
Flart and Hierarchy name space.
(1) Fully Qualified Domain Name (FDDN). An FDDN is a domain name that contains the full name of a host. It contains all the label from the most specific to the root in a domain tree. ADNS server can only match an FDDN to an address.
(2) Partially Qualified Domain Name (PDDN) starts from a node, but it does not reach the root. It is used when the name to be resolved belong to the same site as the client.
