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.

Client-server applications

Client-server is a model we can use to create distributed applications, which are applications that run on more than one machine.

The idea behind the client-server model is that we have at least two computers involved. One acts as the server, and all the others have the role of the client. Clients and servers need to communicate with each other. It is always the client who initiates the communication. Sometimes the server communicates with several clients at once; other times, the server only communicates with a single client at a time.

This means that we can use different computers to take care of different parts of an application's responsibility. We can let one computer deal with one aspect of a problem and another computer work on a different aspect of the same problem. These two computers then need to communicate their results, usually to a single computer, which can then assemble the different results into one solution.
