Physical topologies show the physical interconnection of devices. Logical topologies show the way the network will transfer data between connected nodes. The PHY sublayer specifies that the stations must use the 4B/5B encoding. With this encoding, the transmitter groups the bits by 4 and converts each 4-bit word into a 5-bit word specified by the encoding table.
Is that collision is an instance of colliding while contention is struggle, contest, strife, argument, debate. Addressing – This field helps to direct the frame toward its destination.

In this work, we focus on experimental performance investigation of the delay-tolerant CFDP in the deferred NAK mode over a simulated low earth orbit -satellite communication link. This work is to see how the delay-tolerant CFDP protocol performs over a … In my previous post, I outlined the major factors affecting network performance, including geographic delay , serialization delay , and variable contention delay . Therefore, contention delay is the biggest factor affecting WLAN performance that WLAN administrators have direct control over to optimize the performance of their networks.
Dhafi Quiz Is an online learning educational site to provide assistance and insight to students who are in the learning stage. They will be able to easily find answers to questions at school.We strive to publish wrhl news Encyclopedia quizzes that are useful for students. With the advent of full-duplex switched Ethernet, the need to for CSMA/CD was eliminated and is no longer used when a full-duplex link is present.
Token passing flourishes in an environment where a large number of short data frames are transmitted. This media access control policy is highly efficient in avoiding a collision. Possession of the free token is the only key to transmitting data by a network node. Each terminal holds this free token for a specific amount of time if the network with the high priority does not have data to transmit, the token is passed to the adjoining station in the network.
A contention can occur in data communications when no station is designated a master station. What method is used to manage contention-based access on a … Bandwidth is the data transfer capacity of a computer network in bits per second . The term may also be used colloquially to indicate a person’s capacity for tasks or deep thoughts at a point in time.
