Waiting time for a 100 Mbps broadcast channel is 0.512 ms
Recall that with the CSMA/CD protocol, the adapter waits K * 512 bit times after a collision,
where K is drawn randomly. For K = 100,
The one bit time for 10 Mbps is 1/10000000 s = 0.0001 ms
The one bit time for 100 Mbps is 1/100000000 s = 0.00001 ms
Waiting time for a 10 Mbps broadcast channel is K*512*0.0001= 5.12 ms
Waiting time for a 100 Mbps broadcast channel is K*512*0.00001= 0.512 ms

What is a collision in Ethernet?</h3>
- A collision happens on a half-duplex Ethernet network when two devices on the same network attempt to communicate data at the exact same time.
- The two transmitted packets are "collapsed" by the network, which results in the network discarding both of them.
- On Ethernets, collisions are unavoidable.
- A collision is a momentary interaction between two bodies or more than two bodies at once that modifies the motion of the bodies involved as a result of the internal forces at work.
- Collisions entail the application of force (there is a change in velocity).

Answer:
The method in Java is as follows:
public static int numUnique(int list[]) {
int unique = 1;
for (int i = 1; i < list.length; i++) {
int j = 0;
for (j = 0; j < i; j++) {
if (list[i] == list[j])
break;
}
if (i == j)
unique++;
}
return unique;
}
Explanation:
This line defines the numUnique method
public static int numUnique(int list[]) {
This initializes the number of unique elements to 1
int unique = 1;
This iterates through the list
for (int i = 1; i < list.length; i++) {
The following iteration checks for unique items
int j = 0;
<em> for (j = 0; j < i; j++) {
</em>
<em> if (list[i] == list[j]) </em><em>If current element is unique, break the iteration</em><em>
</em>
<em> break; </em>
<em> }
</em>
if (i == j)
unique++;
}
This returns the number of unique items in the list
return unique;
}
The file that contains full and incremental back-up information for use with the dump/restore utility is <u>/etc/dumpdates.</u>

<h3>What is dump/restore utility ?</h3>
Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. Subsequent incremental backups can then be layered on top of the full backup.
The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Single files and directory subtrees may also be restored from full or partial backups in interactive mode.
