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

Answer:
Assuming this is Python, I would do something like the following:
Explanation:
hourWage= float(input ("What is your hourly wage?: "))
regularHours= float(input ("How many regular hours did you work this week?: "))
overtimeHours= float(input ("How many overtime hours did you have this week?: "))
overtimeWage= (1.5*hourWage)
totalWeeklyPay= (hourWage*regularHours)+(overtimeHours*overtimeWage)
print= ("Your total weekly pay is: " ,totalWeeklyPay)
I hope this works!
In many, many ways. Here's some things you can talk about:
•Previously we stored patient data by hand on paper. Now we use computers to store it. This is better because what if we accidentally lost/destroyed the papers or it burned down? With computers this risk is minimised.
•We can now diagnose patients with problems with much more precision thanks to advances like MRI scanning, CT scans, and X-rays. This means we can pinpoint problems rather than guess what’s wrong.
•Prescriptions for medicine can now be arranged online and delivered to your door in some areas, whereas previously you would have to walk in and get the medicine which could be time consuming.
•We now have phones to dial 911 for emergency ambulance services. This has revolutionised how quickly responders can respond to life threatening events.
There’s much more to talk about, but all of the points above are a sold start.
