The hard drive, along with the files on it, and the operating memory (RAM) represent the warehouses, and the different protocols are the transportation systems, which provide the input and output of information. There are many processes running on a computer, and they represent the workshops and production lines in a factory. This rough comparison makes it easier to imagine the level of complexity present in a contemporary computer. In order to understand what it means to program, we can roughly compare a computer and its operating system to a large factory with all its workshops, warehouses and transportation. It is the software that makes computers valuable to the end-user, allowing for many different types of services that change our lives. In reality, it is not the computers, but the programs (the software), which run on them, that matter. It’s not an overstatement to say that computers build the neural system of our contemporary society and it is difficult to imagine its existence without them.ĭespite the fact that computers are so wide-spread, few people know how they really work.

They have countless applications in the business world, the entertainment industry, telecommunications and finance. We use them to solve complex problems at the workplace, look for driving directions, have fun and communicate. Nowadays computers have become irreplaceable. It will help us with our exploration of the features of the platform and the language. We will review the MSDN Library – the documentation of the. We will use the C# language to write our first computer program, compile and run it from the command line as well as from Microsoft Visual Studio integrated development environment. We will examine what tools we need to program in C#. NET platform and the different Microsoft technologies used in software development. We will familiarize ourselves with programming – what it means and its connection to computers and programming languages.īriefly, we will review the different stages of software development. In this chapter we will take a look at the basic programming terminology and we will write our first C# program.
