Complete Question:
Recall that with the CSMA/CD protocol, the adapter waits K. 512 bit times after a collision, where K is drawn randomly. a. For first collision, if K=100, how long does the adapter wait until sensing the channel again for a 1 Mbps broadcast channel? For a 10 Mbps broadcast channel?
Answer:
a) 51.2 msec. b) 5.12 msec
Explanation:
If K=100, the time that the adapter must wait until sensing a channel after detecting a first collision, is given by the following expression:
The bit time, is just the inverse of the channel bandwidh, expressed in bits per second, so for the two instances posed by the question, we have:
a) BW = 1 Mbps = 10⁶ bps
⇒ Tw = 100*512*(1/10⁶) bps = 51.2*10⁻³ sec. = 51.2 msec
b) BW = 10 Mbps = 10⁷ bps
⇒ Tw = 100*512*(1/10⁷) bps = 5.12*10⁻³ sec. = 5.12 msec

<h3>What are the cybersecurity?</h3>
Cybersecurity is the safety of internet-related structures which include hardware, software program and records from cyber threats. The exercise is utilized by people and organizations to defend towards unauthorized get admission to to records facilities and different automated structures.
Cyberattacks can goal a huge variety of sufferers from character customers to organizations or maybe governments. When focused on groups or different organizations, the hacker's aim is normally to get admission to touchy and precious enterprise resources, which include highbrow property (IP), client records or price details.
