Adjust Text Physical

HTML provides a number of tags that are useful to regulate the physical form of text, as shown below:
{<B> Text </ B>} text displayed in bold circumstances.
{<big> Text </ BIG>} text displayed with a size larger than normal size
{<I> Text </ I>} text displayed in an oblique
{<small> Text </ SMALL>} text display size smaller than normal size
{<sub> Text </ SUB>} text is displayed as a subscript
{<SUP> Text </ SUP>} text is displayed as a superscript
{<tt> Text </ TT>} text displayed in a form such as a typewriter typewriting
{<u> Text </ U>} text in the show with the line given below

Avoid Pet Tag Pet Tags are intersected with Other

A tag pair may be in another tag pair. Tag like this is often called nested tags. For example, couples <HEAD> tag and </ HEAD> tag pair is in <HTML> and </ HTML>.
If you write a tag pair, make sure you write correctly. Tag pair that intersects with another tag pair should be avoided, because it can give incorrect results.

Attributes in Tag

Some tags contain attributes therein. Example: <P ALIGN = "CENTER"> In this example, P is the name tag, while ALIGN is an attribute name. In general, involves the value attribute. In the example above, "CENTER" is the value for the ALIGN attribute. Just as the name tag, ALIGN name also does not distinguish small and capital letters.

web technology

In terms of technology used to create dynamic Web, there are two kinds of grouping, namely:• Client-side technology• Server-side technologyWeb 1.Teknologi on the client sideWeb technology on the client side code is implemented by sending HTML or expansion of its own programs and HTML to the client. For example, VBScript code embedded in HTML code will not work if the client browser used does not support it. The advantages of technology on the client side is possible appearance that is dynamic, for example, show the clock in constant flux or to create animated images that follow the mouse pointer movement.Included in the technology on the client side:• Active X Control• Java Applet• client-side script (eg JavaScript)Active X controlsActive X control is a component written using software like Visual C + +. Visual BASIC, or Delphi. If this component be added to Web documents, then the function it supports will be presented in a Web page. For example, Active X controls can be used to display three-dimensional graphics, or even to implement an interactive game.Within HTML documents, Active X controls via the tag attached <object>. In this case the server will transmit the program code that involves Applets and HTML itself.So far only run Active X Windows environment, and only certain browsers (eg Internet Explorer) that can process it.Java AppletApplets are programs written using the Java programming language. This program can be put into a Web page, via an HTML tag called <applet> and can be processed by a browser which can support Java (eg internet explorer and netscape). In this case the server sends the applet and HTML code.In contrast to ActiveX, applet is cross-platform, that is, can run on multiple platforms, as long as it supports the Java platform.Client-Side ScriptScript is a client-side code that is in the attribute to be one with HTML and script code is processed on the client. Two Scripts on the client side JavaScript and VBScript famous. JavaScript is a script that is very popular and can run on almost all modern browsers. As for VBScript only runs on Internet Explorer.When this script is called CSS (Cascading Style Sheets) and known as Dynamic HTML (DHTML) began widely used. This script can be used to format Web pages with scripts written definition of separate or fused with HTML.2.Teknologi Web on the Server sideWeb technology allows processing on the server side code on the server so that code until the user is different from the original code on the server.Pengguanaan advantage of technology on the server side is:1. Reduce network traffic by avoiding conversation back and forth between the client and server.2. Reduce loading time code, since the client just take the HTML code only.3. Preventing an incompatible browser issue4. Client can interact with existing data on the server.5. Prevent the client know the secret code (remember the code that is given to a different client with native code on the server)Some examples of technology that runs on the server are:Common Gateway Interface (CGI)At first, the technology commonly used to present data that is dynamic in the Web environment is the CGI. In principle, the CGI can be written in any language. However, the most popular is perl.CGI weakness lies in the creation process of a request from a client. If there are very many number of requests it will tend to cripple the server.Proprietary Web server APIsMicrosoft and Netscape created the API (Application Programming Interface) which is intended to create dynamic Web applications. Libraries from Microsoft called ISAPI (Internet Server API) and libraries created by Netscape called NSAPI (Netscape Server API). Both the fire is intended to overcome the weaknesses CGI, because both were designed to create a process alone, although there is much in demand.Active Server Page (ASP)ASP is a server-side technologies are used most widely in the Windows environment. Currently in ASP also try to run on platforms other than Windows. Technology continued from ASPs are ASP.netServer-Side JavaScriptServer-Side JavaScript (SSJS) is made from Netscape that is intended to compete with ASP. In practice, this script is less popular.Java Servlets and JavaServer Page (JSP)Both JavaServlets and JavaServer Page using Java language. Therefore the pemogram who are familiar with Java can take advantage of Java features to create sophisticated programs. Unfortunately, though not as difficult as the java language C is still considered complex for the beginner. Therefore, users of Java Servlets and JSP is still inferior to ASP or PHP.PHPPHP is a script that runs on servers and very popular Linux environment. Currently PHP can run on multiple platforms, from UNIX to Windows.

On the Web at a Glance

World Wide Web (WWW) or commonly called by the Web, is one of the Internet resources is growing rapidly. Imformasi Web distributed hypertext approach, which allows a short text is the reference to open another document. With this approach one can obtain hypertext imformasi denngan jump from one document into another document. Documents diaksespun can spread in various countries.
Like a spider web, networking Web has stretched to all corners of the world. Not only limited to research institutions who wish to publish results of research, the Web is also widely used by business firms who want to advertise products or to conduct business transactions.

web history

Web history began in March 1989 when Tim Barner-Lee who worked at the European Laboratory for Particle Physics, known as CERN (the European pour la Consei Recherce Nuclaire) located in Geneva, Switzerland, filed a protocol (a procedure to communicate) Internet information distribution system that is used for a variety of information among physicists.
The protocol was then known as the World Wide Web and the protocol developed by the World Wide Web Consorcium (W3C). As is known, the W3C is a consortium of several organizations interested in the development of various standards relating to the Web.

web Applications

At first Web application built using only the language called HTML (HyperText Markup Language) and the protocol in use is called HTTP (HyperText Transfer Protocol). In the next development, a number of scripts and objects developed to expand the capabilities of HTML. At this time, many scripts like that; among others, PHP and ASP, while an example in the form of objects, among others, is an applet (Java).
The web application itself can be divided into:
• Static Web
• Web dianamis
Static web formed using HTML alone. Shortage of such applications lies in the necessity to maintain a continuous program to follow the changes that occur. Overcome this weakness in the model of dynamic Web applications.
By extending the capabilities of HTML, by using additional software, peruubahan information in Web pages can be addressed through changes to the data, rather than through changes in the program. For implementation, the Web application can be connected to the database. Thus the information changes can be made by the operator or responsible for the recency of data, and not the responsibility of pemogram or Webmaster.
