Answer:
attached below
Explanation:
<u>To derive the equation we have to make some assumptions </u>
assumptions:
Assume T depends on Z alone
Assume uniform thermal and electrical conductivities (k and ke) in the wire, Assume a uniform heat
transfer coefficient h from the wire to the air stream.
attached below is the required derivation of the equation
Carrier sensing can transmit the data at anytime only the condition is before sending the data sense carrier if the carrier is free then send the data.
But the problem is the standing at one end of channel, we can’t send the entire carrier. Because of this 2 stations can transmit the data (use the channel) at the same time resulting in collisions.
There are no acknowledgement to detect collisions, It's stations responsibility to detect whether its data is falling into collisions or not.
<u>Example: </u>
, at time t = 10.00 AM, A starts, 10:59:59 AM B starts at time 11:00 AM collision starts.
12:00 AM A will see collisions
Pocket Size to detect the collision.
CSMA/CD is widely used in Ethernet.
<u>Efficiency of CSMA/CD:</u>
We are given number of collisions (contentions slots)=4.
