Is the Internet Different?. History: many types of communications. Course Objective. Explore the technologies that make up the modern internet, and how they affect you. 2. Physical Transmission. Wireless media. 3. Transmission is sent and received through invisible waves. Less expensive than copper or fiber optic lines. . Allows the user to move freely around the office or campus and still remain connected to the network. Components of a computer network:. Computer with NIC (PCs, laptops, handhelds). routers & switches (IP router, Ethernet switch). Links” Transmission media” (wired, wireless). protocols (IP,TCP,CSMA/CD,CSMA/CA). Introduction. One of the major functions of physical layer is to move data in the form of electromagnetic signals across a transmission medium.. Thus, the data must be transformed to electromagnetic signals to be transmitted.. NETWORKING CPT.2. MR. . AKWETEY HENRY MATEY .
