Medium: Definition and Exploration In the studied context, the term medium refers to the third party or a tool used for communicating a particular message. This definition applies both to information technology as well as to seances. When it comes to information technology, a medium refers to the physical transmission medium or a presentation medium, which explains such terms as multimedia and advertising media. According to the definition given by Marshall MacLuhan and Lapham (1994) from their book Understanding Media: The Extensions of Man, “the medium is the message” (p. 7). Therefore, there are both personal and social consequences associated with any medium. MacLuhan and Lapham (1994) wrote that a medium is the “result from the new scale that is introduced into our affairs by each extension of ourselves, or by any new technology” (p. 7). In the example of information, new patterns of human association tend to eliminate jobs, which is the negative result of emerging mediums. From a positive perspective, automation initiated through media creates new roles for people, which facilitates the depth of involvement and human association. When discussing the categories of communication media, there are physical and mechanical types. Physical communication media are further divided into verbal and non-verbal based on how they are exercised. Verbal communication is associated with the use of sounds and language for transferring a certain message. Verbal communication is a vehicle for expressing desires, concepts, and ideas that are essential for learning. Non-verbal communication represents the means of transmitting information through auditory, visual, and kinesthetic channels. Based on these definitions of communication types, physical media can include video conferences, large meetings, close and personal meetings, and word-of-mouth communication. Mechanical communication media is associated with the use of electronic or written channels. These channels can be used as message archives or for presenting a bigger picture or a deeper knowledge. These types of media can be fast and, because of their written quality, are interpreted by readers based on their condition. This means that humor or irony cannot be transferred well through the use of mechanical channels. The kinds of these channels include e-mail, regular letters and newsletters, billboards, the Internet, social media, text messages, and billboards. Thus, mechanical media can be both written and electronic, which depends on how communication is transferred from one person to another. Lastly, when in the exploration of communication media as a vehicle for information transference, it is important to mention that the choice of a communication channel (for instance, verbal or non-verbal) depends on the message that one is trying to transfer. For example, the use of a billboard is warranted when one tries to spread awareness of social issues, such as cooperation or climate change. When giving feedback on the work of an employee, a one-on-one conversation is a best-suited channel. Financial information prompts the use of printer or electronic means while psychosocial issues are best addressed either in group meetings or during individ
