Brief Description of the PHYSICAL LAYER of the transmission control protocol/IP architecture The physiologic bottom consists of the basic ironware transmittal technologies of a network. It is a fundamental layer profound the logical entropy structures of the higher level functions in a network. Due to the overplus of available hardware technologies with widely varying characteristics, this is perhaps the just about complex layer in the OSI architecture. The Physical Layer defines the core of transmitting information spells sooner than packets over a material link connecting network nodes. The bit stream may be grouped into code voice communication or symbols and converted to a physical signal that is transfer over a hardware transmission medium. The Physical Layer provides an electrical, mechanical, and procedural interface to the transmission medium. In a nutshell, the Physical Layer translates logical communication theory requests from the Data affair Layer into hardware-specific operations to affect transmission or reception of electronic signals. 2.
