Diploma Thesis from the year 2006 in the subject Business economics - Information Management, grade: 1,3, Wroclaw University of Technology, language: English, abstract: Since the beginning of mankind until today uncountable many inventions took place and prepared the base for an unbelievably fast development. Compared to the age of our planet the time period between the invention of the wheel 5000 BC [50] and the first computers like the British Colossus computer or Konrad Zuses Z machine is not more than a tiny moment. This development would have been impossible without directed communication, as well as sharing and storing of knowledge. The invention of the computer laid the foundation for the change from the industrial age to the todays information age. As the term information already implies, the economical focus in this age has changed from industrial production to information and information processing. This means that today the value of information is significant for economics and business. However, information gets a value just when it is exchanged, which makes it necessary that communication takes place. Otherwise nobody would be interested in buying or selling information. In todays business information can be exchanged in various ways. Communication can take place between people; it can be an interaction between a person and a computer or between computers only. For all these interactions communication systems are necessary. They have a wide range of structure and specification, depending on the media and contents which have to be communicated. These systems shall provide the infrastructure for an effective work which helps to save money and time and at the same time helps to remain compatible and to develop further.In the here presented diploma work I will focus on Communication Systems in Modern Business Management Structures - Needs, Requirements and Solutions. This means that I will examine needs and requirements which are set by modern companies to communication systems and which solutions are offered to them.
