Concept explainers

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

please answer carefully
Suppose you open your BMCC mailbox first thing on a Monday morning and find that your messages have arrived. Assuming the BMCC server does not have access to the MAC address of the device reading these emails. Explain in detail how the ARP protocol determines which device on the LAN will be the recipient of incoming Internet data. After 22 years, the transition to IPv6 addressing is complete for around 30 percent of Internet traffic. When comparing IPv4 and IPv6 address headers, the Ethernet frames' Maximum Transmission Unit (MTU) stands out as a potential stumbling block.
6.3B-4. Multiple Access protocols (4). Consider the figure below, which shows the arrival of 6 messages for transmission at different multiple access wireless nodes at times t=0.1, 0.8, 1.35, 2.6, 3.9, 4.2. Each transmission requires exactly one time unit. t=0.0 1 U r 1 U 3 2 4 Again consider the CSMA protocol (without collision detection), indicate those packets where the channel is sensed busy and therefore, under CSMA, that message transmission is not attempted. [Again, you should assume that it takes .2 time units for a signal to propagate from one node to each of the other nodes. You can assume that if a packet experiences a collision or senses the channel busy and that that node will not attempt a retransmission of that packet until sometime after t=5. Hint: consider propagation times carefully here]. 5 2 3 a t=1.0 t=2.0 4 t=3.0 56 t=4.0 t=5.0

You can assume that if a packet experiences a collision or senses the channel busy and that that node will not attempt a retransmission of that packet until sometime after t=5.
