tailieunhanh - Lecture Network Fundamentals – Chapter 8: OSI Physical Layer

This chapter explain the role of Physical layer protocols and services in supporting communication across data networks, describe the role of signals used to represent bits as a frame as the frame is transported across the local media, describe the purpose of Physical layer signaling and encoding as they are used in networks.
