The objective of this report is to browse the problems that hamper data transmission over a Public Switch Telephone Network (PSTN) and to see how these dilemmas are defeated. Also, this report explains the layers involved in internet communication, specifically the TCP/IP.
This report begins with an introduction to the need for communications. Subsequently, the report demonstrates the telephone and at the outset, the use of it, and how it has changed progressively to follow the demands of modern communication.  The end of the report explains the need for the layer model, especially the TCP/IP and how it was generated from a previous network model, the OSI layers scheme. This report shows the rapid changes and the dilemmas that are facing present day communications. The information that is used for the report subject headings was all derived from different resources, such as books, websites, and journal articles.  </mods:abstract><mods:classification authority="lcc">LD.
