The CSMA stands for Carrier sense multiple access a method for accessing underlying shared channels eg LAN for sending a frame. Explain the need for different types of MAC layer protocols like ALOHA CSMA CSMA-CA and CSMA-CD Different protocols are required for different types of shared media. Carrier Sense Multiple Access Csma Computer Notes CSMA Random Access Protocol CSMA stands for Carrier Sense Multiple Access. . In contrast to CSMACD Carrier Sense Multiple AccessCollision Detection that deals with collisions after their occurrence CSMACA. Within the data link the MAC sublayer implements channel access. CSMACD stands for Carrier Sense Multiple Access Collision Detection is a network protocol for carrier transmission. You must explain your selection clearly in order to receive marks. It is used in the 80211 Ethernet network. It is operated in the medium access control layer. Carrier Sense Multiple Acces...
Ii absorbs 125 J of heat and does 687 J of work. What is the change in internal energy for a system undergoing an endothermic process in which 292 kJ of heat flows and where 370 kJ of work is done on the system. Open Vs Closed Vs Isolated Thermodynamic Systems Thermodynamics Internal Energy Free Energy A Consider the point particle system. . Where W is the work done by the system. B As work done by the system increase and the heat added to the system decrease the internal energy of the system decrease. The internal energy of a system may change when. Answer 1 of 3. If the system goes from A to B by a reversible path and returns to state A by an irreversible path what would be the net change in internal energy. If the system goes from A to B by a reversible path and returns to state A. Heat released Q-50 j. Iii evolves 280 cal of heat and has 125 kJ of work done on it. Q ΔU W-50 ΔU 80. Henc...
