Answer:

warehouse

Explanation:

A bit similar to a database, a data warehouse is a collection or large store of data from different sources that businesses and organization can use to make intelligent business decisions. The data sources for a data warehouse are typically databases from different vendors and architectures.

Data warehouses are typically data repositories used by organizations for data analysis and reporting purposes.

Final answer:

A data warehouse is a centralized repository that aggregates data from multiple sources to support decision-making applications and generate business intelligence. Evaluating the credibility of these sources and utilizing information technology can greatly enhance the quality and usability of the data.

Explanation:

The blank in the question should be filled with the term data warehouse. A data warehouse is a centralized repository that stores data from multiple sources. This data is often gathered from sources that record, analyze, and interpret primary data, which is critical for generating valuable business intelligence. It's essential to evaluate the credibility of these sources to ensure the data's accuracy and reliability.

Data becomes valuable information once it's put into context, analyzed to answer questions, or used within analytical frameworks. Information technology, particularly computers, greatly facilitates this transformation by automating repetitive tasks, managing data storage efficiently, and providing various tools for data analysis.

Sources of data can be incredibly diverse, ranging from satellites and grocery store scanners to traffic sensors and smartphone apps. These capabilities help businesses and organizations in making strategic decisions and forecasting future trends.

Answer with Explanation:

Constraints are a very important feature in a relational model. Constraints are useful because they allow a designer to specify the semantics of data in the database. They are the rules that force Database Management Systems (DBMSs) to check that data satisfies the semantics.

Data integrity is the overall completeness, accuracy and consistency of data. This can be indicated by the absence of alteration between two instances or between two updates of a data record, meaning data is intact and unchanged

Referential integrity (RI) is a method for ensuring the “correctness” of data within a Database Management System. It embodies the integrity and usability of a relationship by establishing rules that govern that relationship.

Proper database RI ensures data integrity for both planned application programs and for queries in ad hoc SQL statements and BI tools.

By defining referential constraints, you can set up the database to control the semantic accuracy of the data it contains. To define a referential constraint, you must create a primary key in the parent table and a foreign key in the dependent table.

You must also define what actions are allowed when data is added or modified. This is accomplished with a set of rules applied to each relationship. The combination of the primary and foreign key columns and the rules that dictate the data that can be housed in those key columns can be defined to ensure correct and useful relational databases.

So, it is a good physical database design practice to implement referential integrity using database constraints.  

Answer:

There are 7 layers in linux.

Explanation:

As networking is difficult and complex.

Imagine if every application had to know how to communicate on every step that would be more than just complex. So, rather than reinvent something which will help it to communicate let’s just make something that will automatically controls the communication and for that protocols came in to live.

As for the linux operating system, it is not exceptional from other operating systems.

There are 7 layers on network protocol stack use to communicate with other network protocol stack.

1. Application layer

2. System call interface

3. Protocol agnostic interface

4. Network protocol

5. Device agnostic interface

6. Device drivers

7. Physical hardware

All the layers vary in their functionality.

One more important thing to remember is that the network protocol stack layers is not one way its 2 way communication. First, when a client request to a network and second, when the request is full filled.

The top most layer is a part of user space, the next five layers comes in the kernel space and the final layer is the physical layer.

Application layer:

When a client or user request to  a network the request initially comes to this layer.

On this layer we use tcp/ip protocol.

System call interface(SCI):

When application layer make a call to the kernel this layer handles that call. And take the request to the next layer.

Protocol agnostic interface:

This layer has two functions “talking” or “listening”. There is a thing called sockets which perform these functions and each socket has an id which is used specifically for an application.

Network protocol:

This layer is used for how the data is sent or received.

Device agnostic interface:

It is used to connect data from/to kernel user space and the network device drivers which allows the data to prepare itself for transmission over the medium from the network device.

Physical hardware :

This layer is responsible for the data packets transmission and received from the network medium being used whether cable or wireless.

cout<<"enter temperature in Fahrenheit ="

cin<<f;

c=(f-32)/1.8;

cout<<"/n Temperature in Celsius ="<<c;

getch();

}

Explanation:

The conversion formula from Fahrenheit to Celsius is given as:

C= (F-32) x 5/9

we take an input in Fahrenheit and put in above formula and covert it in Celsius.

To Temperature conversionfrom Fahrenheit to Celsius, the formula is 'temperatureCelsius = (temperatureFahrenheit - 32) * 5/9'. This can be implemented as a statement in a program to assign a variable as needed, and the specifics of use will depend on the requirements of the program and language used.

To convert Fahrenheit to Celsius, we use the formula:

temperatureCelsius = (temperatureFahrenheit - 32) * 5/9

In programming, you can implement it as a statement that assigns the Celsius equivalent to a variable:

Example in Java:

int temperatureFahrenheit = 77;

double temperatureCelsius = (temperatureFahrenheit - 32) * 5.0/9.0;

System.out.println(temperatureCelsius);

This will directly convert the Fahrenheit temperature to Celsius. The specifics of how you would use this statement depend on the requirements of your program and the programming language you're using.

   public static void main(String[] args) {

       Scanner in = new Scanner (System.in);

       System.out.println("Enter a string Value");

               counter++;

           }

       }

       return counter;

   }

}

Final answer:

The CountVowelsModularized program is a Java application that counts the number of vowels in a string via a dedicated method. The program treats 'a', 'e', 'i', 'o', and 'u' as vowels and does not count 'y'. The solution demonstrates a modular design in which functionality could be easily modified or expanded.

Explanation:

The question asks to write a program named CountVowelsModularized which includes a method that counts the number of vowels in a provided string. In this case, the vowels to be counted are a, e, i, o, and u. The letter y will not be considered a vowel for this particular task. Below is an example code written in Java that demonstrates how you could implement such a program:

This modularized approach provides a clear path to expand or modify the program, should the definitions of vowels change or additional functionality be required.

Cloud computing is a platform that provides online server services for an individual or a group of clients. The cloud computing services are of four types, namely, SaaS (software as a service), IaaS (infrastructure as a service), PaaS (platform as a service) and MaaS (mobility as a service).

The SaaS is used by web or email services, where the server sends or loads the application data to the client, and all data can be viewed and modified on the copy of the data sent to the client.

Final answer:

The Java program uses a for loop to calculate the sum of the first 9 positive integers. The sum variable is increased by val each loop iteration, while val is incremented by 1. The output of the program is therefore 45.

Explanation:

The student asked about the output of a Java program with a for loop that calculates the summation of numbers. To determine the output, we can trace the loop's execution. Starting with int sum = 0, we enter the for loop, which initializes int k = 0 and will iterate until k is greater than 8. On each iteration, the current value of int val is added to sum, and then val is incremented by 1. Thus, the loop runs 9 times (from k = 0 to k = 8 inclusive) and sums the numbers 1 through 9. We end up with sum equalling the sum of the first 9 positive integers, which is 45. Hence, the output printed to the console is 45.

B.) Deterrent

Explanation:

Final answer:

Backup of server data provides a Corrective control in the case of a system issue, being used to restore systems to their previous state after a problem has occurred.

Explanation:

The type of control that backup of server data provides in case of a system issue is Corrective. This is because backups are used to restore data and systems to their last known good state after an adverse event has occurred, correcting the impact of the event.

Backups do not prevent issues from happening, nor do they deter potential problems; their main purpose is to correct the state of the system after an issue has happened. They also do not typically detect issues, as their role is primarily focused on recovery.

It's important to note that organizations often develop a Corrective and Preventative Action plan to manage potential issues identified through processes like Statistical Process Control discussed in class.

Answer:

The main functionality verified by this test method command is user sharing record.

Explanation:

Generally, every apex code runs in system mode.

Apex is strong object-oriented programming language that allows the developers to execute flow and transaction control.

Using syntax which look like java and acts as databases, Apex allows the developer to add any type of business logics to an event which can include button, clicks records or visual pages.

Apex code can be initiated by web service request.  

The permissions and record sharing of current user are not consider by apex codes.

Now the system method runAs() will allow you to take or write a test method which will basically change the user context to an existing or an new user, so that the record sharing will take place.

runAs() command will not change or anything done with user permissions or permission levels, it will only record sharing of the user.  

When you use runAs() command the original and true context will run after the test method is once completed under the command of runAs().

The runAs() has no concern with the user license.  

If there is no or expired your personal or organization license you can just make a new user with this runAS() command.

In using this command we have to make a private class by the name of this test and then our further code to make a user , afterwards  which we will the true and original code of ours which we want to run.

There are many other uses of runAs() like  

 Mixed DML operations in test by opening the DML operations.

 We can also use it as a version which will take a package as a version argument. This will cause the code a specific version.

runAs(System.Version) is the command used for this.

Explanation:

Output of given program:

In the given program, it will not print any value because in while loop semi colon is used which is not valid.

Program Explanation:

In the above C language program header file is included, which provides features to use basic function then the main method is defined inside this method an integer variable "i" declare, that holds a value which is "0".  In this method, the do-while loop is defined. In the do section, we print value and in the while block checks the condition which is i is less than 5.

Answer:

#include <stdio.h>

void main()

{

int i = 0;

do{

printf("%d ", ++i);

}

while (i < 5);

i=i+1;

}

}

Explanation

The #include needs to include something and that's the standard input and output which is coded has stdio.h

In the do while loop what it does is print the value of I while I is less than 5 and you increment I value so as to prevent infinite looping

Parameters are simply placeholders (sometimes called dummy variables) used mainly by methods to perform their given tasks so as to provide controlled variability in  the program(or algorithm). Sometimes they are called arguments. But then it is much more specific to simply use parameters rather than arguments because arguments are the variable values that the parameters are serving as placeholders for.

Parameters identify and describe values that are passed into a function or subroutine.

Parameters are also used for simulation and testing purposes where the input s to the program are or can be varied.

(b) 1500 = 0011 1010 1001 1000

(c) 100 = 0000 0000 0110 0100

(d) -923 = 1111 1100 0110 0101

Explanation:

NOTES:

First Note: The question requests that the numbers be represented in word-length. That means they should be represented in 16bits (a word is 2 bytes).

Second Note: To convert a number to its 2's complement representation,

(i) if the number is positive, the usual conversion to binary will suffice. You might just need to add zero at the beginning of the sequence of bits to ensure that the leftmost bit is a zero(0).

(ii) if the number is negative, then;

=> convert the magnitude of the number to its binary

=> add zeros to the beginning of the sequence of binary until the sequence has the specified length

=> flip each bit in the sequence and add 1 to the result.

SOLUTION:

Applying the rules in the notes above, lets convert the numbers.

(a) 845 => The number is positive, conversion to its binary will suffice

2  |  845

2  |  422 R 1

2  |  211 R 0

2  |  105 R 1

2  |  52 R 1

2  |  26 R 0

2  |  13 R 0

2  |  6 R 1

2  |  3 R 0

2  |  1 R 1

2  |  0 R 1

Writing the remainders upwards, we have

845 = 1101001101

Pad with zeros to convert it to its word-length representation.

845 = 0000 0011 0100 1101

(b) 15000 => The number is also positive, so following the same step as above,

15000 = 11101010011000

Pad with zeros to convert it to its word-length representation.

15000 = 0011 1010 1001 1000

(c) 100 => The number is also positive, so following the same step as above,

100 = 1100100

Pad with zeros to convert it to its word-length representation.

100 =  0000 0000 0110 0100

(d) -923 => The number is negative;

-->  first convert its magnitude (923) to binary

923 = 1110011011

--> Pad with zeros to convert it to its word-length representation.

923 =  0000 0011 1001 1011

--> Flip the bits

0000 0011 1001 1011 = 1111 1100 0110 0100

--> Add 1 to the result above

1111 1100 0110 0100 + 1 = 1111 1100 0110 0101

Therefore;

-923 = 1111 1100 0110 0101

The word length 2's complement representations are:

a. 845: 001101001101

b. 15000: 0011101101100000

c. 100: 0000000001100100

d. -923: 1111110001000101

We have,

To find the word-length 2's complement representation of each decimal number, we first need to determine the binary representation of the absolute value of the number and then convert it into its 2's complement form if the number is negative.

Assuming the word length is 16 bits:

a. 845:

Binary representation of 845: 0011 0100 1101

Since it is positive, the 16-bit 2's complement representation remains the same: 0011 0100 1101

b. 15000:

Binary representation of 15000: 0011 1011 0110 0000

Since it is positive, the 16-bit 2's complement representation remains the same: 0011 1011 0110 0000

c. 100:

Binary representation of 100: 0000 0000 0110 0100

Since it is positive, the 16-bit 2's complement representation remains the same: 0000 0000 0110 0100

d. -923:

Binary representation of 923: 0000 0011 1011 1011

To find the 16-bit 2's complement representation, we first invert all the bits: 1111 1100 0100 0100

Then, add 1 to the inverted value: 1111 1100 0100 0101

So, the 16-bit 2's complement representation of -923 is: 1111 1100 0100 0101

Thus,

a. 845: 001101001101

b. 15000: 0011101101100000

c. 100: 0000000001100100
