Answer:
A bus is characterized by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel.
In computer architecture, a bus (related to the Latin “omnibus”, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.)

Complete Question:
Fill in the missing step in the following deadlock situation. Two users from the local board of education are each running a program (P1 and P2), and both programs will eventually need two DVD drives to copy files from one disc to another. Only two DVD-R drives are available and they’re allocated on an “as requested” basis. Soon the following sequence transpires:
1. P1 requests drive 1 and gets it.
2. ____
3. P1 requests drive 2 but is blocked.
4. P2 requests drive 1 but is blocked.
a.P1 requests drive 2.
b.P2 requests drive 2 and gets it.
c.P2 requests drive 1 but is blocked.
d.P1 releases drive 1.
Answer:
Soon the following sequence transpires:
P2 requests drive 2 and gets it.
Explanation:
A deadlock is a condition where two computer programs allocate the same resource essentially prevent access by each other and both programs stop working.
When every process or thread is awaiting for a resource to be released which is managed by another process a number of processes or themes are blocked.
Here is an example of a deadlock scenario. All connections are blocked; everybody hopes to see an incident that never takes place.
Answer:
Explanation:
The following code is written in Java and like requested prompts the user for a number to continue or a letter to exit. Then loops and keeps adding all of the numbers to the sum variable and adding 1 to the count for each number entered. Finally, it prints the sum and the average using printf and the variables.
import java.util.Scanner;
class Examine1 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int sum = 0;
int count = 0;
System.out.println("Enter a number to continue or a letter to exit.");
while(in.hasNextInt()) {
System.out.println("Enter a number:");
sum += in.nextInt();
count += 1;
}
System.out.printf("The sum is %s.%n", sum);
System.out.printf("The average is %s.", (sum / count));
}
}
