Computer Generation

We have study history subject in our school days in those time history was common for all student but in college level its get divided on behalf of time like Ancient, Middle and Modern history. The Topic computer generation is also dividing on time. We read what type of hardware was used on time to time in computers .So Generation is computer history based on hardware. There are five generation

First Computer

There is no easy answer to this question because of all the different classifications of computers. The first mechanical computer created by Charles Babbage doesn't really resemble what most would consider a computer today. Therefore, this document has been created with a listing of each of the computer firsts starting with the Difference Engine and leading up to the types of computers we use today. Keep in mind those early inventions that helped lead up to the computer such as the abacus, calculator, and tablet machines are not accounted for in this document.

Graph Tutorial

Bipartite Graph

A Graph G is divided into two finite Set U,V such that each vertex of U is connected to each vertex of V in  such a manner where no vertex is adjacent of same, i.e. U set vertex will not connected of any other vertex of U.

In bipartite graph it is necessary that each vertex must be connect with different color otherwise graph is not bipartite

Complete bipartite graph

In regular bipartite graph G(U,V) ,each Vertex U(n) and V(n) connected each other 

A complete bipartite graph is a graph whose vertices can be partitioned into two subsets V1 and V2 such that no edge has both endpoints in the same subset, and every possible edge that could connect vertices in different subsets is part of the graph. That is, it is a bipartite graph (V1, V2, E) such that for every two vertices v1  V1 and v2 V2, v1v2 is an edge in E

Database Model

Hierarchical  

A hierarchical database model is a data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships: each parent can have many children, but each child has only one parent (also known as a 1-to-many relationship). All attributes of a specific record are listed under an entity type.

Example of a hierarchical model

In a database an entity type is the equivalent of a table. Each individual record is represented as a row, and each attribute as a column. Entity types are related to each other using 1:N mappings, also known as one-to-many relationships. This model is recognized as the first database model created by IBM in the 1960s.

PHP form tutotial

An HTML form is a section of a document containing normal content, markup, special elements called controls (checkboxes, radio buttons, menus, etc.), and labels on those controls. Users generally "complete" a form by modifying its controls (entering text, selecting menu items, etc.), before submitting the form to an agent for processing (e.g., to a Web server, to a mail server, etc.)

Methods

The method attribute specifies how to send form-data (the form-data is sent to the page specified in the action attribute).

The form-data can be sent as URL variables (with method="get") or as HTTP post transaction (with method="post").

Notes on GET:

• Appends form-data into the URL in name/value pairs
• The length of a URL is limited (about 3000 characters)
• Never use GET to send sensitive data! (will be visible in the URL)
• Useful for form submissions where a user want to bookmark the result
• GET is better for non-secure data, like query strings in Google

Notes on POST:

• Appends form-data inside the body of the HTTP request (data is not shown is in URL)
• Has no size limitations
• Form submissions with POST cannot be bookmarked

How to Cancel PHP form submission using javascript

<?php 

$msg="";

if(isset($_POST['submit']))

{

$msg="ok";//put your code here

}

?>

Save Record on php server

Hi....

I spend lot of time to achieve this. I Searched many website but didn’t find a proper way which help me to do this. Then I use php manual which help me to find my solution.

Mostly we use  mysql_connect("localhost","root","") this will work on client side where you develop your application. You just have to change the format of  mysql_connect()  function and rest of the thing will be same as you used to on your client.

mysql_connect("localhost","Girfa","12345")

Girfa is your user name and 12345 is password of your website. Which you got when launch your website.

        mysql_select_db("basant_bsw",$con);
        $roll=$_GET['roll'];
        $nm=$_GET['name'];
        $ct=$_GET['city'];
        $quary="insert into stu values('$roll','$nm','$ct')" or die("error in making sql");
        mysql_query($quary,$con) or die("unable to run sql quary");     
       

    }
