When we visit a site must have the impression arises in us, for example, in terms of design or interactive side, like bhinneka.com, amazon.com, ebay.com, etc., and do not forget to also sure we've fill something in a good site that a guest book, polls, email and others. Then we can also look at the page as the current date, time, and number of visitors who have seen the site. Before we to the material, it helps us advance horrible way of working Internet in the form of the concept of client server applications. We do not need discuss how the data runs and passes to destination with a variety of devices for computer networks would not be covered in one chapter out. The concept of client server connection and communication is conducted two computer where one side acts as a client and the other as a server, a server only serves help client and the client sends or ask for a process on the server. Web created with an HTML coding language, so that it can be an interactive web development programming in order to create an interaction between the visitor and the site, there are many languages that can be used such as ASP, PHP, Javascript, and others. For example, when we go to a particular site, there is a hit counter, clock, and a guestbook, and polls page. Then the basic question of how do we make it, whether it can be realized by using only HTML, or need a Another script to make it happen. The answer to this HTML code can realized by a very simple and limited capabilities.
Overview How it Works Web
At the moment we are typing something in the browser address, the data will be passed by the HTTP protocol through the port 80 on the server. This address is the URL of a site that has a unique address on the Internet. Web browser will send a sebelumnyua the agreed rules, This rule commonly referred to as a protocol, stadar protocol using TCP / IP, This process begins with a 3-way handshakes between the source and destination. Web browser, an application on the client that will display a web page from internet sites. Web browser installed on the user side (OS) displays interpreting the information to a computer coding language HTML, which homepage contains images, sounds, multimedia, and other resources that can accessible. Coding in HTML files provide data to the browser what to displayed to the client side. HTML content that will be displayed instead of but the browser from the web server and browser will menginterpret HTML tags to link to the next page For example, we enter the address in the browser http://hardskills.blogspot..com then what will happen is the client request will be forwarded to a webserver that has a specific address such as 202.179.81.90, so easy to remember the writing using the DNS service, which control for had to change the IP address of a word that is easy to remember such as http://hardskills.blogspot.com
Web Programming ASP
ASP was first introduced to the world by Microsoft on July 16 1996, and was given the code name Denali. Beta version was released in November In 1996, and eventually ASP Version 1.0 was officially sold to the public at dated December 12, 1996. Microsoft continues to develop ASP. We can use notepad to write down the codes and will be executed by the browser, but this time there are a lot of programs for web editor like Dreamweaver highly favored because performance author. So that ASP can run local in computer it takes a localhost web server like IIS (internet information server) or PWS (personal web server) that is on the cd Windows. As mentioned at the beginning that we would ASP programming 'paste' in plain HTML code. ASP is VBScript and JScript interpreter on the web server, to date there are technologies that terayar Microsoft ASP.NET integrated in Microsoft.Net. When we use VBScript to be executed on the server, we
named ASP and if executed on the client (browser) then we call VBScript. To find out the process of installation and IIS servers and PWS please read the posts made earlier authors.
