In this TCP/IP - Network Access Layer, you will learn about the bottom most layer of TCP/IP protocol suit and what are the different functions of TCP/IP Network Access Layer. The Network Access Layer of the TCP/IP model is associated with the Physical Layer (Layer 1) and the Data Link layer (Layer 2) of the OSI model. The Network Access Layer's function is to move bits (0s and 1s) over the network medium. The OSI Physical layer is responsible for converting the frame into a stream of bits suitable for the transmission medium. The OSI Physical layer manages and synchronizes signals for the actual transmission.
