Exploring the Basics of Programming the World Wide Web

Programming the World Wide Web 8th Edition PDF

Programming the World Wide Web is a text for computer science students. It provides the background and skills necessary to build Web sites that provide users with information they want, and advertisers with the advertising revenue they need. Chapter 1 begins with an introduction to the Internet and the World Wide Web. It discusses the history of and some of the features of Web browsers and servers, including uniform resource locators (URLs).


In 1989, a group of scientists at CERN (Conseil Europeen pour la Recherche Nucleaire, or European Organization for Particle Physics) led by Tim Berners-Lee proposed a new protocol and system of document access on the Internet called the World Wide Web.3 This system enabled researchers anywhere in the world to access documents stored on document-serving computers located throughout the Internet. The documents could be textual or, more commonly, they included images and other kinds of media. They were linked by hypertext, which allowed nonsequential browsing of textual material.

In early 1993, Mosaic, developed at the National Center for Supercomputer Applications (NCSA) in Champaign, Illinois, introduced graphical user interfaces for accessing the Internet, including Web sites. This chapter introduces the purpose and characteristics of Web browsers, introduced in Section 3, and Web servers, introduced in Section 4. It also describes uniform resource locators, introduced in Chapter 5, which specify addresses of resources on the Web.


The World Wide Web was first developed in the mid-1990s as a means to distribute and present information over computer networks. It used hypertext to allow nonsequential browsing of textual documents. This concept had previously appeared in systems such as Xerox’s NoteCards and Apple’s HyperCard.

The Web uses a variety of protocols to communicate between browsers and servers. Section 7 presents an introduction to the most popular of these, Hypertext Transfer Protocol (HTTP).

The Web requires many different technologies to function, including client-side scripting languages such as JavaScript and Flash, and server-side programming languages such as XML, Servlet, and Ajax. This chapter explains the basic concepts of each of these technologies and how they work together to form the Web. It also discusses uniform resource locators (URLs), which identify locations of resources on the Web.

Object-Oriented Programming

Object-oriented programming is a software development technique that uses objects to represent data and their functions. Programmers then create code to manipulate the objects, and this type of programming is well suited for large, complex, active programs that need frequent maintenance.

Unlike procedural programming, which has a tendency to duplicate code in violation of the “Don’t Repeat Yourself” (DRY) principle, OOP allows developers to extract and reuse code that has already been written, using the concept of class inheritance. A class is a template for creating an object, with properties and methods that all objects of that class will share.

Object-oriented languages include Smalltalk, C++ and Java. In addition, Eiffel and a number of dynamic languages, such as Python and Ruby, have added object-oriented features.

Data Structures

Data structures are the basic building blocks of computer programs. They organize data values in a way that allows them to be searched and retrieved efficiently. They can be grouped into different categories, such as linear, dynamic and non-linear data structures.

Linear data structures are those that have each element connected to the previous and next elements. This arrangement makes it easier to traverse them in a single run. Examples include linked lists, stacks and queues.

Non-linear data structures are those that don’t have a set sequence of connecting their elements. These are more difficult to implement but can be more efficient in terms of memory utilization. Examples of these are trees, BST and graphs.

Web Design

As web design has become an established career path for over two decades, a number of conventions have emerged. Some of these are standard website layouts, grid systems and mobile-first design. These conventions are important to know, as they ensure that designs meet user expectations.

To develop a web site, one must be familiar with these conventions and how to implement them using modern Web development technologies. Programming the World Wide Web provides an introduction to these techniques in a manageable progression, so that readers with previous programming experience can employ them effectively. A discussion of uniform resource locators (URLs) is also included. This chapter introduces these concepts to prepare students for later chapters that provide a complete overview of the web frameworks available.

Developing Good Programming Habits

Programming Habits

Developing good programming habits is essential to being a successful programmer. It’s important to be aware of the bad habits that can sabotage your productivity and learn to avoid them at all costs.

Good coding gets the job done, but great coding goes a step further by being easily readable and understandable. Let’s take a look at some of the most common bad programming habits that new programmers should avoid.

1. Taking care of your code

It’s a good idea to periodically look over the whole code base to refresh your memory and notice any redundancies or inconsistencies. This will also help you catch any “code smells” before they turn into full-blown problems.

Taking care of your code is one of the most important programming habits you can develop. It will not only make your code easier to maintain, but it will also help you avoid bugs and other issues down the road.

One way to take care of your code is to follow the Boy Scout’s motto and “leave it better than you found it”. This means that every time you change a piece of code, try to make it better than it was before. This will make it easier for other programmers to understand and maintain your code in the future.

2. Keeping track of your progress

A good programmer needs to have a solid understanding of core computer science and programming language concepts. However, building these skills takes more than just learning the basics of a programming language. In order to be a great programmer, you need to develop a set of habits that will help you get the most out of your time and effort.

One of the most important programming habits is to always document your code. This will save you a lot of headaches down the road, especially if you ever need to revisit your code. It will also make it much easier for other programmers to understand your code.

The key is to always document your code in a way that is easy to understand. This means avoiding confusing abbreviations and naming variables with descriptive names.

3. Keeping your code organized

One of the most important things a programmer can do is keep their code organized. This makes it much easier for others to read and understand the code, and it can also help you find errors quickly.

This means keeping things like coding conventions in place, naming variables and methods appropriately, and using proper indentation. It also means dividing your code into sections, or “blocks”, so that it’s easy to see what each section does.

It’s a good idea to also keep your files and folders organized, so that it’s easy to find what you’re looking for when you need to make changes. This can help you avoid a lot of headaches down the road! And of course, it’s always a good idea to back up your work.

4. Taking the time to read other people’s code

Programming is an inherently collaborative endeavor. That’s why it’s important to have good programming habits that help you communicate and collaborate effectively. These habits also help you solve problems efficiently and creatively.

Programmers should be in the habit of documenting their code. This is a great way to make the code easier to read and maintain, and it helps other programmers understand what you were trying to accomplish. It’s also a good idea to practice lean coding, which is the process of stripping code down to its bare essentials. This can help your code run more quickly and use less memory.

When you’re stuck on a problem, it’s important to take the time to read other people’s code. This can help you figure out what’s going on and give you ideas for how to fix your own code.

5. Taking the time to learn new things

Learning new things is essential for any programmer. It improves your efficiency, increases your problem-solving skills, and can ultimately help you solve more complex issues. However, many developers struggle to make time for this learning.

Developing programming habits takes time and dedication. It can be helpful to find a mentor or buddy who will help you stay motivated, and it’s important to avoid distractions like social media and TV. Additionally, it’s important to track your progress and avoid imposter syndrome, which can hinder your ability to develop good programming habits.

If you want to improve your programming skills, start by building a few small behaviors and practicing them regularly. You’ll be amazed at the difference this makes. Good luck!
