To display or distribute information from a database, programmers or database administrators create ___ .

Answers

Final answer:

To display or distribute information from a database, programmers or database administrators create reports

Explanation:

Reports are objects within a database management system (DBMS) that present data in a formatted, reader-friendly manner. The information for these reports is sourced from tables or queries within the database, known as the report's record source. Among various objects in a DBMS, such as tables, queries, and user interfaces, forms are also crucial. Forms provide an interactive interface to the data stored in the database, potentially improving data entry efficiency and limiting access to sensitive information.

A database uses a structured collection of data files managed by a DBMS. Essential tasks like the creation, storage, maintenance, and retrieval of data are facilitated by the DBMS, which can be accessed through software packages like Microsoft Access, Oracle, or FileMaker Pro. This streamlines operations for a variety of sectors, including business, government, and personal uses.

A call to a value-returning function with an empty formal parameter list has the form ________ .
a. function name
c. void function name
c. function name(void)
d. functionname()

Answers

The correct answer is D

Final answer:

A call to a value-returning function with an empty formal parameter list has the form functionname(). This signifies no input arguments and is used when a function does not require any arguments to perform its task. D is correct.

Explanation:

A call to a value-returning function with an empty formal parameter list has the form functionname(). This indicates that the function does not take any arguments. When we define a function call, we specify the name of the function followed by an argument list enclosed in parentheses. However, in this case, the parentheses are empty because the function does not require input arguments.

It's important to note that the type of return value a function provides is declared by the keyword before its name. If the keyword is void, it means that the function does not return a value. Functions in programming are designed to perform computations or actions; they may 'take' input arguments and 'return' a result, this result is known as the return value.

Given a scanner reference variable named input that has been associated with an input source consisting of a sequence of integers and an int variable named total, write the code necessary to add all the integers in the input source and place their sum into total.

Answers

Answer:

Following are the code written in the Java Programming Language.

total = 0;   //set integer type variable and initialize to 0

while(input.hasNextInt()){   //set the while loop

total += input.nextInt( );  //code is here

}

Explanation:

Here, in the following code create the reference scanner class object i.e., "input".

Then, we set integer data type variable "total" and initialize 0 in it. then, we set the while loop and pass the following condition "input.hasNextInt()". Then, we add all integer values and store their sum in the variable "total".

In this example, the program uses a Scanner to read integers from the input source (which could be the console or a file) until there are no more integers to read (input.hasNextInt() returns false).

What's the program about?

import java.util.Scanner;

public class SumIntegers {

   public static void main(String[] args) {

       Scanner input = new Scanner(System.in); // Assuming input comes from the console

       int total = 0;

       while (input.hasNextInt()) {

           int num = input.nextInt();

           total += num;

       }

       System.out.println("Sum of integers: " + total);

       input.close(); // Don't forget to close the scanner when you're done using it

   }

}

To make active directory more manageable, it is divided into the domain partition, configuration partition, and what other partition?

Answers

The answer is schema partition. To make Active Directory more manageable, it is divided into the domain partition, configuration partition, and schema partition partition.  Only one schema partition exists per forest. It is stored on all domain controllers in a forest. 

Final answer:

Active Directory is organized into partitions such as the domain partition, configuration partition, and the schema partition, with the schema containing definitions for all AD objects and attributes.

Explanation:

The Active Directory (AD) in Windows Server environments is divided into several partitions to make it more manageable. These partitions include the domain partition, the configuration partition, and the schema partition. The schema partition is where definitions of all AD objects and their attributes are stored. It is essentially a blueprint for the structure of the Active Directory's directory service. This design helps in separating different types of information for easier management and to allow for replication only where necessary.

List the seven steps used by a laser printer to print a page

Answers

The seven steps used by a laser printer to print a page are :
1)  Processing, this is where he computer sends the data to the printer.
2)  Charging, where the wire (primary corona) negatively charges the
     photoconductive drum.
3)  Exposing, where the laser scans the image to the drum. Anywhere the
     laser touches the drum causes the electrical charge to drain off.
4)  Developing, where negatively charged toner particles are allowed to
     attach to the painted area of the drum; since the negative charge has
     been drained off these areas
5) Transferring, where the transfer corona wire charges the paper with a
     positive charge from behind. The negatively charged toner jumps to the
     positive paper, according to the image on the drum. A Static Charge
     eliminator then removes any residual charge.
6) Fusing, where the toner particles attached to the paper are fused or
     melted to the paper, because of the heated drum.
7) Cleaning, where the drum is cleaned of excessive toner and electrical
    charges.

You relate tables to one another by using Matching fields

Explanation:

If there are more than one table in the database, then mostly there would be a relationship existing between the two table.

For Eg. There would be Department table where this table contains details of department number, department name and Name of the primary incharge, etc. There would be a table called “Employee” where it would contain the name of the employee along with his personal information and there would be a column where each employee would be associated with the department and would contain a field called as “department number”.

So here the database contains more than one table and these two are related using department number which is common to both the table.

which of the following is not a renewable resource

solar energy

wind

Answers

Hey there! :) 

A renewable source is a resource that can be used to power up something. It can also be reused - meaning that it can be used over and over again. Renewable sources are also able to be replaced naturally, meaning that once that specific resource runs out, it be be replenished without the creation or usage of a machine or man made resource. 

Oil is NOT considered a renewable resource because it's a fossil fuel.

Solar energy IS a renewable resource because we have an infinite amount of solar power! 

Some types of lumber ARE considered renewable simply because trees can be regrown, thus creating an infinite cycle of tree growth and renewable energy.

Wind IS considered a renewable resource because wind can be generated without the usage of machines, and it's also renewable because of how limitless it is! 

So, our answer is the first answer choice : oil.
