Students working at individual PCs in a computer laboratory send their files to be printed by a server that spools the files on its hard disk. Under what conditions may a deadlock occur if the disk space for the print spool is limited
Answers
Answer:
Explanation:
Disk space is a limited resource on the spooling partition and once it is filled the will cause a deadlock. Every single block that comes into the spooling partition claims a resource, and the one behind that wants resources as well, and so on. Since the spooling space is limited and half of the jobs arrive and fill up space then no more blocks can be stored, causing a deadlock. This can be prevented allowing one job to finish and releasing the space for the next job.

Brainy has a computer and wants to perform an upgrade. He has two sticks of RAM of his computer ( total 3 GB) and he noticed it gets very slow. He has also noticed that the sluggishness matches an increase in the hard drive activity. What is likely the cause of Brainy's problem? What can you recommend as a fix ?
Answers
Brainy's issue is most likely due to a shortage of RAM.
How can this be explained?The computer's limited 3 GB of RAM may pose a challenge in managing numerous operations, and consequently may heavily depend on virtual memory, causing heightened hard drive activity and a reduction in overall efficiency.
My suggestion to resolve this issue would be to enhance the RAM. By adding more RAM to the computer, its memory capacity will enhance, leading to a reduction in dependence on virtual memory and an enhancement in overall efficiency, as it will be able to stock and access a greater amount of data.
Enhancing the system's memory capacity by installing a RAM of 8 GB or more is likely to alleviate the issue of slow performance.

Answers
Answer:
Explanation:
The following Python program has a function called addDigits which takes a number as a parameter and returns the sum of the digits. Then the program creates a loop that keeps creating random numbers between 222 and 1000 and divides it by the value returned from the function addDigits. If the remainder is 0 is prints out a statement and breaks the loop, ending the program. The picture below shows the output of the program.
import random
def addDigits(num):
sum = 0
for x in str(num):
sum += int(x)
return sum
sum = addDigits(random.randint(222, 1000))

int m2 = p.getMoney(); // assignment 2

else if (m1 > 50000)
p = new Retired(...);
int m3 = p.getMoney(); // assignment 3

a. Person
b. Student
c. Employee
d. Retired
e. This cannot be determined by examining the code
Answers
Answer:
a. Person
Explanation:
The reference getMoney() is a method that is part of the Person class. This can be proven with the code since subclasses can access methods from the parent class but a parent class cannot access methods from the child classes. Since Student, Employee, and Retired are all child classes that extend to the Person parent class then they can access getMoney(), but unless getMoney() is in the Person class, then a Person object shouldn't be able to access it. Since the first object created is a Person object and it is accessing the getMoney() method, then we can assume that the getMoney() method is within the Person class.

The database engine is a large data store gathered from a wide range of sources within about an undertaking or Old to inform management decisions.
We study the database system and big data reasonably Information storage of Big Data is applied to the difficulty of storing data.
Big Data is a new term used to identify datasets due to the size and complexity. A database server is a given database category.
They are used to store huge quantities of data, such as analysis, historic or consumer data, but instead produce large reports and mines.
In the database system, the complexity of unstructured data is sung easily.
The challenge of big data is one of the most exciting opportunities for those decades to come.
A database server is a centralized relation server, where all the attractive data from different systems is gathered together.
They must wash and structure your data at the position of insertion before placing them inside a warehouse. This process is usually alluded to as ETL Extract, Transform, and Load.
