Answer:
Explanation:
To maintain data consistency and integrity in a large multi-user system, transactions are completed concurrently with the aid of concurrency management techniques.
The following are some of the benefits of concurrent transaction processing and execution versus serial transaction processing and/or execution:
Improved Resource Usage:
A transaction frequently combines both CPU and Input/output activities, resulting in better resource usage. Computers have the ability to run disks and CPUs in parallel. As a result, transactions can also be executed in parallel, with one employing the usage of the CPU and the other using the disk. As a result, resources are better used than in serial transaction processing and execution.
Improved throughput:
Running transactions in parallel has an immediate impact of increasing throughput since a greater number of transactions can be completed in the same period of time.
Lower/shorter waiting time:
Reduced wait time: When transactions are processed sequentially and serially, a short transaction is forced to wait for a longer transaction. Because transactions usually affect distinct portions of the database. As such, it's best if they happen at the same time i.e it is run concurrently.
The characteristics listed above are critical to a system's performance.
Thus, It is obvious that the benefits of concurrency exceed the extra programming work necessary to execute transactions concurrently. As a result, database systems must handle concurrent transactions despite the additional work necessary since it is worthwhile.
what would be the result of running these two lines of code
Ski
Surf
Jog
Hike
Answer:
Jog
Explanation:
The variable options is a list containing 5 string values
options = ["ski", "surf", "jog", "bike", "hike"]
Indexing in python starts from 0 ; hence the index values of the list values are :
0 - ski
1 - surf
2 - jog
3 - bike
4 - hike
The statement ;
print(options[2]) means print the string at index 2 in the list named options
The string at index 2 is jog ;
Hence, the string jog is printed.

SummaryIn this lab, you complete a partially written C++ program that includes a function named multiplyNumbers() that multiplies two int values to find their product.Three ints should be passed to the multiplyNumbers() function, the two numbers to be multiplied (num1 and num2) should be passed by value, and another int (product) to hold the product of the two numbers should be passed by reference, enabling the multiplyNumbers() function to change its value.The source code file provided for this lab includes the necessary variable declarations and input and output statements. Comments are included in the file to help you write the remainder of the program.Instructions:Open the source code file named MultiplyTwo.cpp using the code editor.Write the multiplyNumbers() function, the function declaration, and the function call as indicated by the comments.Execute the program by clicking "Run Code."Rewrite the multiplyNumbers() function to pass the two numbers (num1 and num2) by value and to pass product by address.Execute the program. It should generate the same output.// MultiplyTwo.cpp - This program calculates the product of two numbers.// It demonstrates pass by reference and then pass by address.// Input: None// Output: The product of two numbers#include using namespace std;// Write function declaration hereint main(){int num1 = 10;int num2 = 20;int product = 0;// Print value of product before function callcout << "Value of product is: " << product << endl;// Call multiplyNumbers using pass by reference for product// Print value of calculated productcout << num1 << " * " << num2 << " is " << product << endl;return 0;} // End of main function// Write multiplyNumbers function here; use pass by reference for result of multiplication. Then use pass by address.
Answer:
Declare the method prototype using:
void multiplyNumbers(int x, int y,int &product);
Call the function using:
multiplyNumbers(num1, num2,product);
Lastly, the method is as follows:
void multiplyNumbers (int x, int y,int &product) {
product = x * y;
return; }
Explanation:
Declare the method prototype using
void multiplyNumbers(int x, int y,int &product);
Call the function using
multiplyNumbers(num1, num2,product);
The method is as follows; the & written in front of product implies that product is passed by reference
void multiplyNumbers (int x, int y,int &product) {
This calculate the product
product = x * y;
This returns nothing
return; }

Consider the following statements, taken from three different Jack programs. In each one of these programs, the identifier foo represents a different thing: let x = 5 + foo - a // program 1. Here foo represents a simple variable. let y = foo[12] - 3 // program 2. Here foo represents an array. let z = 2 * foo.val() // program 3. Here foo represents an object. Suppose that we are parsing any one of these statements (we don’t know which), and that the current token is foo. What kind of parser do we need to determine if we have a simple variable, an array reference or a method call?
Answer:
instanceOf
Explanation:
The parser that would be best suited for this scenario would be the instanceOf keyword, which is part of the javaParser class. This keyword allows you to check if a variable is a simple variable, an array reference or a method call through an IF statement. If it is equal to the compared type it will return a boolean value of True, otherwise it will return False. This keyword is used in Java and Javascript to check the type of the variables in scenarios such as this one.
a) Which two technologies you would suggest to making tolling process fast?
Write an application that determines whether the first two files are located in the same folder as the third one. The program should prompt the user to provide 3 filepaths. If the files are in the same folder display All files are in the same folder, otherwise display Files are not in the same folder.
Answer:
The program in Python is as follows:
fname1 = input("Filepath 1: ").lower()
fname2 = input("Filepath 2: ").lower()
fname3 = input("Filepath 3: ").lower()
f1dir = ""; f2dir = ""; f3dir = ""
fnamesplit = fname1.split("/")
for i in range(len(fnamesplit)-1):
f1dir+=fnamesplit[i]+"/"
fnamesplit = fname2.split("/")
for i in range(len(fnamesplit)-1):
f2dir+=fnamesplit[i]+"/"
fnamesplit = fname3.split("/")
for i in range(len(fnamesplit)-1):
f3dir+=fnamesplit[i]+"/"
if f1dir == f2dir == f3dir:
print("Files are in the same folder")
else:
print("Files are in the different folder")
Explanation:
The next three lines get the file path of the three files
fname1 = input("Filepath 1: ").lower()
fname2 = input("Filepath 2: ").lower()
fname3 = input("Filepath 3: ").lower()
This initializes the directory of the three files to an empty string
f1dir = ""; f2dir = ""; f3dir = ""
This splits file name 1 by "/"
fnamesplit = fname1.split("/")
This iteration gets the directory of file 1 (leaving out the file name)
for i in range(len(fnamesplit)-1):
f1dir+=fnamesplit[i]+"/"
This splits file name 2 by "/"
fnamesplit = fname2.split("/")
This iteration gets the directory of file 2 (leaving out the file name)
for i in range(len(fnamesplit)-1):
f2dir+=fnamesplit[i]+"/"
This splits file name 3 by "/"
fnamesplit = fname3.split("/")
This iteration gets the directory of file 3 (leaving out the file name)
for i in range(len(fnamesplit)-1):
f3dir+=fnamesplit[i]+"/"
This checks if the file directories hold the same value
This is executed, if yes
if f1dir == f2dir == f3dir:
print("Files are in the same folder")
This is executed, if otherwise
else:
print("Files are in the different folder")

Write a function that accepts a positive random number as a parameter and returns the sum of the random number's digits. Write a program that generates random numbers until the sum of the random number's digits divides the random number without remainder. assembly language
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))
while True:
myRandomNum = random.randint(2, 99)
if (sum % myRandomNum) == 0:
print("No remainder between: " + str(sum) + " and " + str(myRandomNum))
break
Write an algorithm to sum to values
Answer:
There is no need to make an algorithm for this simple problem. Just add the two numbers by storing in two different variables as follows:
Let a,b be two numbers.
c=a+b;
print(c);
But, if you want to find the sum of more numbers, you can use any loop like for, while or do-while as follows:
Let a be the variable where the input numbers are stored.
while(f==1)
{
printf(“Enter number”);
scanf(“Take number into the variable a”);
sum=sum+a;
printf(“Do you want to enter more numbers? 1 for yes, 0 for no”);
scanf(“Take the input into the variable f”);
}
print(Sum)

A shop will give discount of 10% if the cost of purchased quantity is more than 1000. Ask user for quantity suppose, one unit will cost 100. Judge and print total cost for user. Plz give answer in C++.
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
int main(){
int qty;
float discount = 0;
cout<<"Quantity: ";
cin>>qty;
int cost = qty * 100;
[tex]i f (cost > 1000)[/tex] { [tex]discount=cost * 0.10[/tex]; }
cout<<"Cost: "<<cost - discount;
return 0;
}
Explanation:
This declares the quantity as integer
int qty;
This declares and initializes discount to 0
float discount = 0;
This prompts the user for quantity
cout<<"Quantity: ";
This gets input for quantity
cin>>qty;
This calculates the cost
int cost = qty * 100;
If cost is above 1000, a discount of 10% is calculated
[tex]i f (cost > 1000)[/tex] { [tex]discount=cost * 0.10[/tex]; }
This prints the cost
cout<<"Cost: "<<cost - discount;

larger and more expensive.
Answer: smaller and less expensive.
Explanation:
As technology advances, the architects of the devices that we use are getting more efficient in the production of said devices such that they are using better materials and techniques in production.
This has led to a situation where devices are increasingly getting smaller in size and cheaper to afford as well. For instance, compare the computers of today to those of the 90's. We have laptops now which are really slim and cost a fraction of what the bulky computers of those days cost.

The process of making changes to an information system to evolve its functionality, to accommodate changing business needs, or to migrate it to a different operating environment is known as _____________ maintenance.
Answer:
Corrective
Explanation:
An information system interacts with the overall system by receiving data in its raw forms and information in a usable format.
Information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.
Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.
Additionally, an information system comprises of five (5) main components;
1. Hardware.
2. Software.
3. Database.
4. Human resources.
5. Telecommunications.
Corrective maintenance can be defined as the process of making significant changes to an information system in order to evolve or transform its functionality, to accommodate and tolerate continuously changing business needs, or to migrate it to a different (new) operating environment.
This ultimately implies that, a corrective maintenance is performed so as to rectify (repair) faulty equipments or systems and to restore an underperforming resource to an operational or optimum status.
