Assume that two students are trying to register for a course in which there is only one open seat. What component of a database system prevents both students from being given that last seat?
Answer:
Transaction isolation
Explanation:
The student that has initiated the transaction before the other one will be given the seat. The database will be locked for the second student during the period of transaction of the first student. The transaction isolation level is a state within databases that specifies the amount of data that is visible to a statement in a transaction, specifically when the same data source is accessed by multiple transactions simultaneously.
The component of the database that prevents both students from getting the last seat is: transaction isolation
Data that enters the database are expected to maintain accuracy and also be consistent with the database structure.
So, when both students request for the last seat, the possibilities are:
Student A gets the seatStudent B gets the seatThe following is not a possibility
Both students get the seatNone of the students gets the seatThe above highlights means that, only one of the students would get the seat.
This is possible because of the concept called transaction isolation.
The transaction isolation ensures that the data requested by a user is complete and such data maintains competency.
So, when a student gets the last seat, the next student would not get the same seat (or any other seat), because a transaction has already been completed.

○ Hanging indent
○ Right indent
○ First Line indent
○ Decrease indent
The First Line indent is shown in the image. Thus, option C is correct.
What is an indent?
An indent is a spacing that results from spacing a block of information farther inside than just the surrounding content. To the right of the start of the following line, an indentation for the inaugural line appears. Many parts must follow first-line spacing according to APA standards.
The very first sentence about a partnership that follows a headline or chapter title is not indented, as was mentioned in the previous section.
The tab key on just about any keyboard automatically indent each sentence that comes after it for you. The different layout is occasionally recommended for specific sorts of writing, including research publications and internal memos. Therefore, option C is the correct option.

How to write a C++ program that allows a user to enter their rating of the three movies in the Dark Knight Trilogy and then display each rating entered, the highest rating, the lowest rating, and the average of the ratings??
The program is an illustration of arrays.
Arrays are used to hold multiple values in one variable.
The program in C++ where comments are used to explain each line is as follows:
#include <iostream>
using namespace std;
int main(){
//This declares an array of three elements for the three ratings
int ratings[3];
//This initializes the sum of the ratings to 0
int total = 0;
//The following iteration gets input for the three ratings
for(int i = 0; i<3;i++){
cin>>ratings[i];
//This calculates the sum of all inputs
total+=ratings[i];
}
//This declares and initializes the lowest and the highest ratings
int lowest = ratings[0], highest = ratings[0];
//This iterates through the array
for(int i = 1; i<3;i++){
//The following if condition determines the lowest rating
if (lowest > ratings[i]){ lowest = ratings[i]; }
//The following if condition determines the highest rating
if (highest < ratings[i]){ highest = ratings[i]; }
}
//This prints the output header
cout<<"The ratings are: ";
//The following iteration prints the three ratings
for(int i = 0; i<3;i++){
cout<<ratings[i]<<" "; }
//The prints the highest ratings
cout<<endl<<"Highest: "<<highest<<endl;
//The prints the lowest rating
cout<<"Lowest: "<<lowest<<endl;
//The prints the average rating
cout<<"Average: "<<total/3<<endl;
return 0;
}
At the end of the program, the ratings entered, the highest rating, the lowest rating, and the average of the ratings are printed.

Python 3.12 LAB: Input and formatted output: Right-facing arrow Given input characters for an arrowhead and arrow body, print a right-facing arrow. Ex: If the input is: * # Then the output is: # ******## ******### ******## #
The code below prints the required shape using the string manipulations in Python.
In Python, if we multiply a character with a number, we get that character side by side that number of times.
For example: 6 * '#' would give us → ######
Also, we can use + sign to concatenate the strings.
For example: 'hi' + ' there' would give us → hi there
We use this approaches to print the required shape line by line.
Comments are used to explain each line.
The output is attached as an image.
#get the characters from the user
base_char = input()
head_char = input()
#set first row with 6 spaces and 1 head_char
row1 = 6 * ' ' + head_char
#set second row with 6 base_chars and 2 head_chars
row2 = 6 * base_char + 2 * head_char
#set third row with row2 and 1 head_char
row3 = row2 + head_char
#print the rows to draw the shape
print(row1)
print(row2)
print(row3)
print(row2)

Name the five automated information systems - The Vendors
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.
