Brief Description of the PHYSICAL LAYER of the transmission control protocol/IP architecture The somatogenetic horizontal surface consists of the basic hardware transmittal technologies of a network. It is a fundamental layer underlie the logical entropy structures of the higher level functions in a network. Due to the overplus of functional 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 selective information crooks or else than packets over a material link connecting network nodes. The bit stream may be grouped into code haggling o r symbols and converted to a physical signal that is communicable 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 liaison Layer into hardware-specific operations to affect transmission or answer of electronic signals. 2.

Physical Layer Technologies/ Features in Wireless Networks The Physical layer takes care of the following issues in wireless data transmission ? Spectrum The part of the electromagnetic spectrum is u sed, what is the overall bandwidth availa! ble, how is this part into impart? Ensures that mechanisms are available to underwrite utilised bandwidth to pick up coexistence with other users of the same spectrum. ? Propagation - Power levels that are permitted by regulatory authorities in the spectrum in question. The mechanisms are available to control the transmitted power or propagation practice session to inform co-channel interference for other users, maximise effective redact or utilise...If you want to get a full essay, mark it on our website: OrderCustomPaper.com
