Answer
Continue on your current heading and maintain your speed unless the vessel required to give way does not act.
Explanation
When two vessels approach each other, the one positioned on the right side is designated as the stand-on vessel, which means the other vessel, the give-way vessel, must yield. In this circumstance, you should keep your course and speed unless the give-way vessel fails to do so. If that happens, you must take evasive maneuvers to avoid collision by steering clear, never turning toward or crossing in front of the other vessel.
Answer:
Benefits of Oral Communication
- Utilizing visual aids such as PowerPoint during discussions can enhance his team's understanding of his concepts and procedures.
- Staff responses tend to be more immediate and sincere compared to written replies.
Drawbacks of Oral Communication
- If Sushant struggles with stage fright or lacks strong communication skills, it may negatively impact the team's perception of him.
- There is a risk that staff may forget portions of Sushant's spoken communication, as written information is generally more reliable for retention.
Benefits of Written Communication
- A well-crafted memo articulates Sushant's ideas and procedures clearly to the staff.
- A feedback questionnaire could be included for staff input.
- Clearly stated goals and objectives.
Drawbacks of Written Communication
- Excessively lengthy written material may pose challenges for comprehension or retention.
It is advisable for Sushant to prioritize written communication to share his ideas and protocols effectively.
Answer:
First I/O instruction format -> 256 ports
Second I/O instruction format -> 65536 ports
Explanation:
- The initial instruction format can address 256 ports, computed from eight bits for port addressing as 2^8 = 256 ports.
- The second instruction format allows for 65536 ports, which can be calculated using sixteen bits for addressing as 2^16 = 65536 ports.
Changing the opcode facilitates the selection between the first and second instruction format, allowing one input or output operation at a given moment.
Answer:
count = 0
while count!= 8:
height = float(input("Enter the height of the rider: "))
if height >= 140:
print("You may ride")
count += 1
else:
if height >= 120:
answer = input("Is the rider accompanied by an adult (yes/no): ")
if answer == "yes":
print("You may ride")
count += 1
else:
print("You are not permitted to ride")
else:
print("You are not permitted to ride")
Explanation:
Begin with a count of zero, which will track the number of riders allowed. Use a while loop that continues until the count reaches 8. During each iteration, request the user's height. If the height is 140 cm or taller, display "You may ride" and increment the count. If the height is 120 cm or more, check if the rider is with an adult. If not, show the message "You are not permitted to ride"; otherwise, allow the ride and increase the count. If the height is below 120 cm, deny the ride.

Explanation:
Dividing this critical section into two parts:
void transaction(Account from, Account to, double amount)
{
Semaphore lock1, lock2;
lock1 = getLock(from);
lock2 = getLock(to);
wait(lock1);
withdraw(from, amount);
signal(lock1);
wait(lock2);
deposit(to, amount);
signal(lock2);
}
This approach is optimal in practice, as separating the critical section avoids any unintended states (for instance, resulting in withdrawing more funds than available).
The straightforward solution of keeping the critical section intact lies in ensuring that locks are acquired in the same order across all transactions. In this scenario, the locks can be sorted, choosing the smaller one to lock first.
