HTML
Hypertext Markup Language, or HTML for short, is a programming language most commonly used to develop websites and offline applications, such as manuals. Though the initial intent of the language was to exchange information from a small network of computers, it is now most often used to share information and allow engagement in online activities throughout a network with an increasing number of host computers. Questions about the development of applications and pages through HTML belong in this category.

Inheritance is an object oriented feature supported by Java wherein the features of one Java class can be inherited/made available in another class. This creates a parent child relationship between these 2 classes. Class Inheritance in java mechanism is used to build new classes from existing classes. The inheritance relationship is transitive: if class x extends class y, then a class z, which extends class x, will also inherit from class y. Object-oriented programming allows classes to inherit commonly used state and behavior from other classes.
Example:
public class Parent {
private String name = "Rocky";
public String getName(){
return this.name;
}
}
public class Child extends Parent {
public static void main(String[] args){
System.out.println("Name in Parent is: " + getName());
}
}
Here the getName() method is available only in the parent class but is directly used in the child class because the method is public and is directly accessible to the child class since it has extended the parent class.
Benefits of Inheritance:
One of the key benefits of inheritance is to minimise the amount of duplicate code in an application by sharing common code amongst several subclasses. Where equivalent code exists in two related classes, the hierarchy can usually be refactored to move the common code up to a mutual superclass. This also tends to result in a better organisation of code and smaller, simpler compilation units.
Inheritance can also make application code more flexible to change because classes that inherit from a common superclass can be used interchangeably. If the return type of a method is superclass
Why should image files on webpages be compressed?

What is the difference in size between a webpage and a HTML document?
Very simply, a website is a collection of one or more web pages designed to convey information on a particular subject or theme to a web user. (e.g. a company will have a web site providing structured information about the company, designed to inform particular groups of its stakeholders - investors, customers, technical support, sales, employment, news items etc.)
A web page is one screen full of information (from a web site) that may contain links to other pages in the web site or links to external information. The web page will normally be written as (or rendered as) an HTML document.
What program do you use to open HTML documents?
You can open them with different things. A browser will display the web page. Any text editor should be able to open the actual file so you can see the code. Anything that can open a text file, like a word processor, will open a html file. Specialise html editors and programs like Dreamweaver can also open html documents.
What is the standard magazine font size?

when you click on it you will go to: page1.HTML

How are opening and closing tags different?
An opening tag is used to indicate the starting point of an action by a tag. The closing tag shows when to stop this action. The front slash is added to a tag, before the tagname, to indicate that it is a closing tag. What is between the tags is effectively selected for this action. To start bolding for example, we use <b> and to stop we use </b> as follows:
This text is <b> bold </b> text.
The word bold in the above sentence would be bolded, as that is what is enclosed by the opening and closing tags. The text outside of that is as normal.
What HTML character symbolizes that the tag is a closing tag?
You are probably referring to the front slash. It, along with the less than sign and the greater than sign and the name of the tag, form an end tag, like this:
</html>
The opening tag does not have the front slash, so it is the character that makes the difference.
Nobody knows for certain who came up with it first. Some say the cavemen or the Chinese, but there seems to be no credible proof of that. The only original source for the idea of the Chinese inventing it and playing the game in a macabre sort of way comes from a movie.
But what we do know is that the game is at least 600 years old. Three Africans, Adelin Zika, Micheal Hud and Kirit Kam, are credited for having invented it.
Augustus Hagerson adapted and popularized the sport in Africa in 1832 and spread the sport to Guam in 1833.
Others claim it began in the US in 1920 by an independent invention. Two men, Walter Young and Philip Livingston, returned from World War I and found work in a factory. They engaged in horseplay at work by throwing a foam ball at each other. One day, the foam ball got into a machine and came out with a fine layer of rubber on it. They were fired for this, but the ball inspired them to create a new sport. While this new sport caught on in Akron, Ohio and surrounding areas, there was little interest beyond Ohio. However, it seems the US Department of Education quickly picked up the game and introduced it as part of physical education in public schools.
