Suppose that a scheduling algorithm (at the level of short-term CPU scheduling) favors those processes that have used the least

processor time in the recent past. Why will this algorithm favor I/O-bound programs and yet not permanently starve CPU-bound programs?

Answer:

Answer of the given question is :

I/O-bound

programs would not require much CPU usage, having short CPU bursts.

CPU-bound programs require large CPU bursts. CPU-bound processes do not

have to worry about starvation because I/O bound programs finish running

quickly allowing CPU-bound programs to use the CPU often.

Explanation:

I/O-bound

is a thread generally has a tight latency that needs a compare to computer bond thread on the windows workload.

When a mouse click then it response ASAP as compared to batch job which is running in the background.

If the outcome is slower, then the user switch the operating systems and server workload does not care about UI

Write a program that calculates an adult's fat-burning heart rate, which is 70% of 220 minus the person's age. Complete fat_burn
Brut [27]

Answer:

def get_age():

age = int(input())

if(age>=18 and age<=75):

return age

else:

raise ValueError("Invalid age.")

def fat_burning_heart_rate(age):

return ((70 / 100) * (220 - age))

if __name__ == '__main__':

try:

age = get_age()

print("Fat burning heart rate for a",age,"year-old:",fat_burning_heart_rate(age),"bpm")

except ValueError as ve:

print(ve.args[0])

print("Could not calculate heart rate info.")

Explanation:

def get_age():

age = int(input())

if(age>=18 and age<=75):

return age

else:

raise ValueError("Invalid age.")

def fat_burning_heart_rate(age):

return ((70 / 100) * (220 - age))

if __name__ == '__main__':

try:

age = get_age()

print("Fat burning heart rate for a",age,"year-old:",fat_burning_heart_rate(age),"bpm")

except ValueError as ve:

print(ve.args[0])

print("Could not calculate heart rate info.")

The above program performs an operation to determine the percentage of fat burning rate.

It takes the value of the ages of some adult as input, performs a series of conditional statement function on them. Before given an output .

Early Intel processors (e.g., the 8086) did not provide hardware support for dual-mode operation (i.e., support for a separate u
Firlakuza [10]

Answer:

Uneven use of resources

Explanation:

Potential problem associated with supporting multi - user operation without hardware support is:

Uneven use of resources: In a situation where we assign a set of resources to user 1 and if a new user comes, then it would be difficult to allocate new resources to him. The processor would get confused between the two users. And the tasks would not be completed. This can affect task processing.

Explain working principle of computer?​
Sonbull [250]

Answer:

The working principle of the computer system. Computers do the work primarily in the machine and we can not see, a control center that converts the information data input to output. This control center, called the central processing unit (CPU), How Computers Work is a very complex system.

1- Design a brute-force algorithm for solving the problem below (provide pseudocode): You have a large container with storage si
sladkih [1.3K]

Answer:

Pseudocode is as follows:

// below is a function that takes two parameters:1. An array of items 2. An integer for weight W

// it returns an array of selected items which satisfy the given condition of sum <= max sum.

function findSubset( array items[], integer W)

{

initialize:

maxSum = 0;

ansArray = [];

// take each "item" from array to create all possible combinations of arrays by comparing with "W" and // "maxSum"

start the loop:

// include item in the ansArray[]

ansArray.push(item);

// remove the item from the items[]

items.pop(item);

ansArray.push(item1);

start the while loop(sum(ansArray[]) <= W):

// exclude the element already included and start including till

if (sum(ansArray[]) > maxSum)

// if true then include item in ansArray[]

ansArray.push(item);

// update the maxSum

maxSum = sum(ansArray[items]);

else

// move to next element

continue;

end the loop;

// again make the item[] same by pushing the popped element

items.push(item);

end the loop;

return the ansArray[]

}

Explanation:

You can find example to implement the algorithm.
