Overview of this book

Learning how to code has many advantages, and gaining the right programming skills can have a massive impact on what you can do with your current skill set and the way you advance in your career. This book will be your guide to learning computer programming easily, helping you overcome the difficulties in understanding the major constructs in any mainstream programming language. Computer Programming for Absolute Beginners starts by taking you through the building blocks of any programming language with thorough explanations and relevant examples in pseudocode. You'll understand the relationship between computer programs and programming languages and how code is executed on the computer. The book then focuses on the different types of applications that you can create with your programming knowledge. You'll delve into programming constructs, learning all about statements, operators, variables, and data types. As you advance, you'll see how to control the flow of your programs using control structures and reuse your code using functions. Finally, you'll explore best practices that will help you write code like a pro. By the end of this book, you'll be prepared to learn any programming language and take control of your career by adding coding to your skill set.

Distributed applications

A distributed application is an application that does not run on one single machine, but instead lets different parts of the program run on multiple computers that communicate with each other over a network. This might sound like the client-server solutions we talked about earlier, but here we don't have the distinct roles of a client and a server.

There could be several reasons to use this solution. One may be that what we are doing requires so much computing power that a single computer will not be enough. The idea is to use the computing power of many computers and distribute the calculations to all of them, letting each computer work on a small section of the problem and communicate the results to the other machines in the network. This will give us something of a supercomputer that will act as a very powerful single machine running a single application, when it is actually thousands of computers running small individual parts of the application...
