Answer:
The computer age introduced a new element to businesses, universities, and a multitude of other organizations: a set of components called the information system, which deals with collecting and organizing data and information.
An information system is described as having five components.
1- Computer hardware. This is the physical technology that works with information.
2- Computer software. The hardware needs to know what to do, and that is the role of software.
3- Telecommunications.
4- Databases and data warehouses.
5- Human resources and procedures.
Explanation:
Computer hardware
This is the physical technology that works with information. Hardware can be as small as a smartphone that fits in a pocket or as large as a supercomputer that fills a building. Hardware also includes the peripheral devices that work with computers, such as keyboards, external disk drives, and routers. With the rise of the Internet of things, in which anything from home appliances to cars to clothes will be able to receive and transmit data, sensors that interact with computers are permeating the human environment.
Computer software
The hardware needs to know what to do, and that is the role of software. Software can be divided into two types: system software and application software. The primary piece of system software is the operating system, such as Windows or iOS, which manages the hardware’s operation. Application software is designed for specific tasks, such as handling a spreadsheet, creating a document, or designing a Web page.
Telecommunications
This component connects the hardware together to form a network. Connections can be through wires, such as Ethernet cables or fibre optics, or wireless, such as through Wi-Fi. A network can be designed to tie together computers in a specific area, such as an office or a school, through a local area network (LAN). If computers are more dispersed, the network is called a wide area network (WAN). The Internet itself can be considered a network of networks.
Databases and data warehouses
This component is where the “material” that the other components work with resides. A database is a place where data is collected and from which it can be retrieved by querying it using one or more specific criteria. A data warehouse contains all of the data in whatever form that an organization needs. Databases and data warehouses have assumed even greater importance in information systems with the emergence of “big data,” a term for the truly massive amounts of data that can be collected and analyzed.
Human resources and procedures
The final, and possibly most important, component of information systems is the human element: the people that are needed to run the system and the procedures they follow so that the knowledge in the huge databases and data warehouses can be turned into learning that can interpret what has happened in the past and guide future action.

Write a program that creates a two-dimensional array initialized with test data. Use any data type you wish. Declare a two-dimensional array of data type char, int, double, or string. Assume the array is declared as follows: const int NUM_ROWS
Question:
Write a program that creates a two-dimensional array initialized with test data. Use any data type you wish. Declare a two-dimensional array of data type char, int, double, or string. Assume the array is declared as follows:
const int NUM_ROWS = 3, NUM_COLUMNS = 5;
test data: [10, 1, 1, 1, 1] [7, 2, 20, 2, 9] [ 3, 3, 3, 3, 5]
Answer:
The program in C++ is as follows:
#include<iostream>
using namespace std;
int main(){
const int NUM_ROWS = 3, NUM_COLUMNS = 5;
int MyArray[NUM_ROWS][NUM_COLUMNS] = {{10, 1, 1, 1, 1},{7, 2, 20, 2, 9},{3, 3, 3, 3, 5}};
return 0;
}
Explanation:
To answer this question, we make use of the following parameters
Array name: MyArray
Array datatype: integer
The explanation is as follows:
This declares the array dimensions
const int NUM_ROWS = 3, NUM_COLUMNS = 5;
This declares and initializes the array with the test data
int MyArray[NUM_ROWS][NUM_COLUMNS] = {{10, 1, 1, 1, 1}, {7, 2, 20, 2, 9}, {3, 3, 3, 3, 5}};
A customer opened a file attachment, and now her PC is infected with ransomware. She's unable to open any of her files. Which action would you take first?
A. Reinstall the operating system
B. Run an antivirus scan
C. Pay the ransom to recover the data
D. Disconnect the PC from the network
E. Restore files from backup
Answer:
D. Disconnect the PC from the network
Explanation:
I'd say this because it keeps the ransomware from spreading to other computers making it a bigger problem.
In this question, the answer is "Option D", which disconnects the PC from the network, which can be defined as follows:
A customer's PC has been attacked using ransomware after she opened a document file. She has been unable to access any of her files. She first had to detach the PC from the system to access the file.This type of malicious software (malware) threatens to publish or prevent information or computer access until the victim pays a ransom price to the attacker. Today, ransomware assaults are all too frequent. This attacker then demands a ransom from the victim, promising to restore access to the information in exchange for payment.The wrong option can be defined as follows:
In option a, it is wrong because when we reinstalling the OS is used to start the fresh without using the old files.In option b, it is wrong because the antivirus can't protect the ransomware maliciously. In option c, it is wrong because when a corporation can pay the ransom, their cash is dispersed across the dark web.In option e, it is wrong because creating copies of information could be recovered in the event of a primary information failure.Learn more:

Return the appropriate part of FizzBuzz This is a small part of a classic software engineering interview question. fizz_buzz_check takes a single integer argument, number. Complete the function such that it returns a value using the following rules: If the number is divisible by 3 (i.e division by 3 has a remainder of 0), return the string Fizz. If it is divisible by five, return the string Buzz. If it is divisible by 3 AND 5, return FizzBuzz. Otherwise, just return the original argument back without any changes.
Answer:
The function in Python:
def fizz_buzz_check(num):
if num%3 == 0:
result = "Fizz"
if num%5 == 0:
result = "Buzz"
if num%3 == 0 and num%5 == 0:
result = "FizzBuzz"
if num%3 != 0 and num%5 != 0:
result = num
return result
Explanation:
The function to complete is not given. So, I write a new function from scratch.
This defines the function
def fizz_buzz_check(num):
This checks if num is divisible by 3
if num%3 == 0:
If yes, the returned value is stored as "Fizz"
result = "Fizz"
This checks if num is divisible by 5
if num%5 == 0:
If yes, the returned value is stored as "Buzz"
result = "Buzz"
This checks if num is divisible by 3 and 5
if num%3 == 0 and num%5 == 0:
If yes, the returned value is stored as "FizzBuzz"
result = "FizzBuzz"
This checks if num is not divisible by 3 and by 5
if num%3 != 0 and num%5 != 0:
If yes, the returned value is stored as the initial argument
result = num
This returns the appropriate value
return result
Write a Python function that takes as input a list, A, and returns two lists L and G. L constains all numbers in A, which are not A[0] and are less than or equal to A[0]. G contains all numbers in A, which are not A[0], and are greater than A[0].
Answer:
In Python:
def split(A):
L=[]; G=[]
for i in range(1,len(A)):
if (A[i] != A[0] and A[i] < A[0]):
L.append(A[i])
if (A[i] != A[0] and A[i] > A[0]):
G.append(A[i])
return L, G
Explanation:
This defines the function
def split(A):
This initializes the L and G lists
L=[]; G=[]
This iterates through the original list A
for i in range(1,len(A)):
This populates list L using the stated condition
if (A[i] != A[0] and A[i] < A[0]):
L.append(A[i])
This populates list G using the stated condition
if (A[i] != A[0] and A[i] > A[0]):
G.append(A[i])
This returns the two lists L and G
return L, G

What is two-dimensional array?Arrays inside of arrays are what are known as two-dimensional arrays. 2D arrays, which are made up of rows and columns, are constructed as metrics. To create a database that resembles the data structure, 2D arrays are frequently used.
You may store a large amount of data using 2d arrays at once, which can then be supplied to as many different functions as necessary. Two indices are used to refer to the position of the data element in two-dimensional or multi-dimensional arrays. Row and column are the two dimensions indicated by the name. Realize is in is in [1][1], Fabric is in [3][2], Bandana is in [2][1] .
Therefore, realize is in is in [1][1], Fabric is in [3][2], Bandana is in [2][1].
