QUESTION 4 1 points [Unit 4) Is the basis of the classic Ethernet LAN, so it is worth devoting some time to looking at it in detail, it is important to realize that collision detection is an analog process. The station's hardware must listen to the channel while it is transmitting. If the signalit reads back is different from the signal it is putting out, it knows that a collision is occurring, CA MACA B.CSMNDC C.CSMNCA DCSMNCD QUESTIONS 1 points Unit 4) As a collision-free protocol, this protocol consists fo exact N slots. If station has a frame to send it transmits a bit during the sloto. No other station is allowed to transmit during this slot. Regardless of what station does, station 1 gets the opportunity to transmit a bit during slot 1, but only if it has a frame queued. In general, station may announce that it has a frame to send by inserting a 1 bit into slot After all slots have passed by, each station has complete knowledge of which stations wish to transmit. At that point they begin transmitting frames in numerical order. What is this protocol called? A Collision Detection B. Collision Avoidence C. Adaptive tree walk protocol D.
