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:
Device driver is the correct answer.
Explanation:
Device driver is the type of computer program that is for every particular computer hardware, it means there are different different types of drivers for every computer hardware. Without the device driver or computer's hardware driver, the following device or the computer system works but not in the proper manner.
Answer:
function userAgeCheck(event){
// if age is in range 18 to 100
// parseInt() converts string into integer
if( parseInt(userAge.value) >= 18 && parseInt(userAge.value) <= 100 ){
// set color to light green
document.body.style.backgroundColor = "green";
userAgeValid = true;
}
else{
// set color to orange
document.body.style.backgroundColor = "orange";
userAgeValid = false;
}
}
