Communication is the process of exchanging information through an agreed-upon character system, or the process of sending information to yourself or any other entity, usually through language. Communication is simply the exchange of information, feelings and ideas, through verbal and non-verbal means, adapted to the social nature of the situation, ie the situational context. The role and purpose of internal communication can be defined as a concern for building two-way, inclusive relationships with internal publics, their employees with task of improving organizational effectiveness. In order to improve internal commnication in all directions, it is necessary to develop an awareness of the importance of internal communication, to build a network of formal internal vertical and horizontal communication in line with the structure of the company and to take care of that network. Today, a relatively small number of organizations have prescribed procedures of using social networks, and the most common reason is ignorance or misunderstanding of management about the importance, pervasiveness and capabilities of social networks. As social networks began to be used more intensively, companies decided to use the learned knowledge of social networks and apply them internally, based on the principle of connecting employees of the company, in order to improve and deepen communication at the business level. In this way, closed, corporate social networks were created, which only employees of the company have access to. The primary research on employees' attitudes towards the influence of social networks in communication in a business environment was made, and the results of the research showed that quick and immediate feedback is the biggest advantage of using social networks in business communication, eliminated time and space constraints are the greatest advantage of using social networks in business communication, misunderstandings or misinterpretation of the reported information is the biggest disadvantage, and that a lack of respect is not the biggest disadvantage of using social network sin business communication.
