Answer:
B. Data Base Management System
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Hence, a software that enables the organization to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data, is called a Data Base Management System (DBMS).
how do computers help us with our homework
xD I don't know if you said this as a joke, or if you're serious, but here:
A computer can be a helpful tool to complete your homework by giving you access to countless sources of information, it can also provide you with educational games which can enhance a child's learning ability by presenting learning as something fun and interactive as opposed to boring loads of repeated work which barely stimulate learning at all. But keep in mind that a computer can also take the opposite effect on a child's brain, and can gradually turn into addiction.
I hope this helps! :D

Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. calcPyramidVolume() calls the given calcBaseArea() method in the calculation.
Answer:
The method in C++ is as follows:
double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
double baseArea = calcBaseArea(baseLength, baseWidth);
double volume = baseArea * pyramidHeight;
return volume;
}
Explanation:
This defines the calcPyramidVolume method
double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
This calls the calcBaseArea method to calculate the base area of the pyramid
double baseArea = calcBaseArea(baseLength, baseWidth);
This calculates the volume
double volume = baseArea * pyramidHeight;
This returns the volume
return volume;
}

Blank Are input instructions you give to a computer
Explanation:
A computer is a machine that can be programmed to accept data (input), process it into useful information (output), and store it away (in a secondary storage device) for safekeeping or later reuse. The processing of input to output is directed by the software but performed by the hardware.
The register in the CPU is not the same as the RAM.

At each step it should print out the move it makes and its performance score (e.g. S 0.2). Every 5 steps, it should print out a grid, with a "[ ]" on the square where the robot is now. Thus, with the above input, if the robot has done S U S L S, the output would be:
Answer:
The output would be S 0.2 U 0.2 S 0.2 U 0.2 L 0.2 S 0.2 [ ]
Explanation:
Given that at each step output prints for example S 0.2.
Also given after every 5 steps, it should print a grid "[ ]".
if robot has been given S U S L S, it prints output as
S 0.2 U 0.2 S 0.2 U 0.2 L 0.2 S 0.2 [ ]

The volumes of data collected by contemporary organizations are so huge that they are beyond the ability of typical DBMS to capture, store, and analyze. These big data may be unstructured or semi-structured and are not suitable for relational DBMS products. What are the new technologies developed to handle the big data
Answer:
Some of the new technologies developed to handle the big data are as follows:
1. In-memory Databases
2. Blockchain
3. NoSQL Databases
4. Edge Computing
5. Streaming Analytics.
6. Artificial Intelligence
Explanation:
Some of the new technologies developed to handle the big data are explained as follows:
1. In-memory Databases: This allows for rapid and easy access to data and analytics, which can be used to inform a variety of business choices. In-memory computing provides the information required to improve marketing, finances, and operations efficiency.
2. Blockchain: Blockchain is the distributed database technology that underpins the Bitcoin digital currency, and it's a darling among forward-thinking analysts and venture capitalists. The distinctive feature of a blockchain database is that data can't be erased or changed after it's been written. Furthermore, it is extremely secure, making it a perfect solution for sensitive industries such as retail, insurance, health care, banking, and among others.
3. NoSQL Databases: NoSQL databases are used to store unstructured data and offer quick performance. This implies it can handle a wide range of data formats in high volumes while remaining flexible. MongoDB, Redis, and Cassandra are examples of NoSQL databases.
4. Edge Computing: Edge computing systems evaluate data very near to where it was originated — at the network's edge — rather than sending it to a centralized server for analysis. An edge-computing system has the advantage of minimizing the quantity of data that must be transferred over the network, therefore lowering network traffic and expenses.
5. Streaming Analytics: By analyzing data as it is created, Streaming Analytics allows for faster and faster access to insights. Streaming Analytics can also take data from a variety of sources, evaluate it, and offer insights almost instantly.
6. Artificial Intelligence: Artificial intelligence has the ability to transform data analytics by learning (from previous analytic activities) and improving the speed and accuracy of outputs over time. Artificial intelligence has the ability to make accurate future predictions based on current events with vast amounts of data to draw from, as well as analytic results from previous inquiries.

17.8.1: Writing a recursive math function. Write code to complete raise_to_power(). Note: This example is for practicing recursion; a non-recursive function, or using the built-in function math.pow(), would be more common.
Answer:
The recursion function is as follows:
def raise_to_power(num, power):
if power == 0:
return 1
elif power == 1:
return num
else:
return (num*raise_to_power(num, power-1))
Explanation:
This defines the function
def raise_to_power(num, power):
If power is 0, this returns 1
if power == 0:
return 1
If power is 1, this returns num
elif power == 1:
return num
If otherwise, it calculates the power recursively
else:
return (num*raise_to_power(num, power-1))

A programmer writes 500 lines of computer code in 17 days. Must there have been at least 1 day when the programmer wrote 30 or more lines of code
Answer:
The answer is No
Explanation:
Given data
Total Lines of code= 500
Number of days= 17 days
Number of codes written per day= 500/17
Number of codes written per day= 29.4117
If we multiply 29.4117 by 17
=499.9989
=500 approx
Hence there was never a day when the programmer wrote 30 or more lines
Advancements in technology often make computer
hardware and software more convenient to use as
well as able to fit a variety of budgets. As
technology advances, it usually gets
smaller and less expensive.
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.
Write a program to prompt the user for hours worked to compute a gross pay for an employee, and he is paid 100/hour. If he worked for 50 hours in a week then he will get overtime pay for the extra hours he worked i.e. he will be paid 1.5 times of M100.00 for 10 hours (50-40)
Answer:
rate = 100
hours_worked = eval(input('enter number of hours worked'))
gross_pay = hours_worked * rate
if hours_worked <= 40 :
print(gross_pay)
else:
print(gross_pay + (1.5*rate*(hours_worked -40)))
Explanation:
Using python 3 :
The rate of pay is defined using the rate variable
The user is the prompted to enter the number of hours worked.
Gross_pay gives the mathematical evaluation of the amount paid base in rate and hours worked.
Since hours beyond 40 are paid as overtime. Then we have to add that to those who worked above 40 hours.
If hours_worked is 40 and below, then use gross pay
If gross pay is above 40 ; then the overtime fee is added to gross pay using the rate provided.

Task folders, simply allows an individual organize their tasks in a logical manner. It performs an identical function just like a file directory.
Folders can be created in the root folder. Once can also create them as subfolder in the other files. The task details, appointments and the to do list can be viewed in the task folder.
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)

I need solutions to below questions with python code:
Write a program, my_family.py For Loop A program, work-list.pyList
1. that contains a Tuple holding the names of friends or family members. Then use a For Loop to read and print the names.
2. that contains a of six integers. Use a list method to add one more integer. Use a list method to sort the list. Use a While Loop to print the entries.
Answer:
1) my_family.py
family = ('Dad', 'Mom', 'Agnes', 'David', 'Chris', 'Millie')
for name in range(len(family)):
print(family[name])
2) work_list.py
my_number = [2, 6, 3, 1, 8, 4]
# add items at the end of the list.
my_number.append(0)
my_number.append(5)
# sorts the list, default - ascending.
my_number.sort()
size = 0
while size < len(my_number):
print(my_number[size])
size += 1
Explanation:
The tuple and list data structures are ordered, using indexes to locate items in its container.
The family.py file uses the for-loop to iterate and print the family names in the tuple.
The work-list.py file contains a list of integers which is modified by adding items at the end of the list with the append method and a prints all the items using a while-loop.

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 code to take a String input from the user, then print the first and last letters of the string on one line. Sample run: Enter a string: surcharge se Hint - we saw in the lesson how to get the first letter of a string using the substring method. Think how you could use the .length() String method to find the index of the last character, and how you could use this index in the substring method to get the last character.
//import the Scanner class to allow for user input
import java.util.Scanner;
//Begin class definition
public class FirstAndLast{
//Begin the main method
public static void main(String []args){
//****create an object of the Scanner class.
//Call the object 'input' to receive user's input
//from the console.
Scanner input = new Scanner(System.in);
//****create a prompt to tell the user what to do.
System.out.println("Enter the string");
//****receive the user's input
//And store it in a String variable called 'str'
String str = input.next();
//****get and print the first character.
//substring(0, 1) - means get all the characters starting
//from the lower bound (index 0) up to, but not including the upper
//bound(index 1).
//That technically means the first character.
System.out.print(str.substring(0,1));
//****get and print the last character
//1. str.length() will return the number of character in the string 'str'.
//This is also the length of the string
//2. substring(str.length() - 1) - means get all the characters starting
// from index that is one less than the length of the string to the last
// index (since an upper bound is not specified).
// This technically means the last character.
System.out.print(str.substring(str.length()-1));
} // end of main method

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;
