Every more or less educated person knows there are lots of companies who deal with computer systems design. These are firms of data processing industry which design software for business, various entertainment purposes and education. At the same time they may write, test, modify and support the mentioned software. Computer systems designers play an important role in the data processing industry functioning because they plan and design computer systems, manage the clients' systems and data processing facilities and, of course, provide other computer-related services and advice. Many jobs in the data processing industry require long hours spent on defining architecture components modules. This is one of the main responsibilities of computer systems designers. On the other hand, some people work in support services (for example, software and hardware troubleshooting); and other ones either design or create computer systems, which belong to them by copyright. It's interesting to admit that many computer systems designers are self-employed or may belong to their employers by copyright. It's a common knowledge that software designed by computer systems designers is called intellectual property. It's considered to be the subject of copyright law (just like works of art, literature, music, etc.). It goes without saying that intellectual property may be sold or licensed to other people. This is a wide-spread practice. It's worthy admitting that self-employed computer systems designers often publish their products and sell them to many customers. But still they should understand the laws of patents and copyright laws. So, the outlook of the computer systems designers' job should be particularly strong because computer systems design is considered to be one of the fastest growing segments of the modern economy. Speaking about computer systems designers, it's necessary to know that they conduct research, improvement and development of various computing concepts and operational methods. On the other hand, they may advice on or be engaged in their practical application. Among the common and important tasks of computer systems designers are researching operational methods and main principles of computers and various computer-based systems for information processing, design, planning, production and process control. At the same time, computer systems designers are responsible for development and maintenance of computer software, data structures, databases, algorithms, robots, artificial intelligence. It's impossible to speak about computer systems designers and not to mention that they maintain management systems of data bases and data dictionaries to ensure the data safety and validity. They are also known to contribute and keep up with modern technical developments of computers and their peripherals, software and computing methods, defining their limitations and potential. Thus, computer systems designers have a wide range of functions in sphere of data processing industry.
