An Administrator wants to make a list of all prospects who complete the Contact Us form but only wants them to be added the first time they complete the form. If a prospect is ever removed from the list, they shouldn't be able to get added back to it. What is the best way to create this type of list
Answer:
The answer to this question can be defined as follows:
Explanation:
The easiest way to build such a list is by using an algorithm rule, where the prospects who complete the form are then matched with the rule and added to the list because the developer would also like to list of the all applicants, who fill out all the contact us Application, but still only prefer to also have them added when they fill-up the form first. When an outlook is ever omitted from the list, it should not be included.

Andy wants the borders to be distinctly visible for each cell in the product details table. Which of the following properties must Andy add to his code to accomplish his goal?
A. border-spacing: length;
B. border-collapse: separate;
C. border-collapse: collapse;
D. border-spacing: initial;
Answer:
CSS documentation
Explanation:
Use this CSS reference to browse an alphabetical index of all the standard CSS properties, pseudo-classes, pseudo-elements, data types, and at-rules. You can also browse a list of all the CSS selectors organized by type and a list of key CSS concepts. Also included is a brief DOM-CSS / CSSOM reference.
Locatiopn: https://devdocs.io/css/
The properties that Andy must add to his code to accomplish his goal is (B), border-collapse: separate.
What is border-collapse?The border-collapse property in CSS determines how the borders of table cells are collapsed. The default value of border-collapse is collapse, which means that the borders of adjacent cells are merged together. To make the borders of the cells in Andy's table distinctly visible, he needs to set the border-collapse property to separate.
The other possible answers are incorrect. The border-spacing property determines the amount of space between the borders of adjacent cells. The border-spacing: initial value sets the border spacing to the default value, which is 0 pixels.

A user reports that he cleared a paper jam and now cannot print. The technician reseats the paper and then prints a test page from the printer. A test page sent from the workstation does not print. Which of the following actions should the technician take first?
a. Check the printer connection
b. Stop and start the printer
c. Reboot the computer
d. Clear the print queue
Answer:
d. Clear the print queue.
Explanation:
If a user reports that he cleared a paper jam and now cannot print. Also, the technician reseats the paper and then prints a test page from the printer. A test page sent from the workstation does not print. The first and most appropriate action the technician should take is to clear the print queue.
In computer technology, a printer is an electronic output device (peripheral) that is used for the printing of paper documents (texts and images).
The print queue is the directory or location where the printing sequence for a printer is stored or backed up. If it was ensured that the power cord of the printer is properly plugged in, the paper jam is cleared and the papers are properly seated, then the next action to take is clearing the printing queue. Once, the printing queue is cleared and becomes empty, the printer will begin to print.
Suppose you have a tablet with a capacity of gigabytes. For a plain text book, one byte typically corresponds to one character and an average page consists of 2000 characters. Assume all gigabytes are used for plain text books. a. How many pages of text can the tablet hold? b. How many 500-page books can the tablet hold?
Answer:
a. 17,500,000 pages
b. 35,000
Explanation:
The computation is shown below:
As we know that
[tex]1 giga\ bytes = 1 \times 10 ^ {9} bytes[/tex]
So for 35 gigabytes it would be
[tex]= 35 \times 10 ^ {9} bytes[/tex]
And it is given that there is 2,000 characters
a. So the number of text pages would be
Let us assume that
for 2,000 it would be 1 page
So for [tex]35 \times 10 ^ {9} bytes[/tex] it would be x
Now we solve the x which is equal to
[tex]= \frac {35 \times 10 ^ {9} bytes}{2,000}[/tex]
= 17,500,000 pages
b. Now for 500 pages, it would be
[tex]= \frac{17,500,000}{500}[/tex]
= 35,000

Sniffer turns the NIC of a system to the promiscuous mode so that it listens to all the data transmitted on its segment. It can constantly read all information entering the computer through the NIC by decoding the information encapsulated in the data packet. Passive sniffing is one of the types of sniffing. Passive sniffing refers to:
Answer:
The right answer will be "Sniffing through a hub".
Explanation:
Packet sniffer seems to be a device that listens for transmitted data on what seems like a channel. Sniffing enables the detection of data by individual people as it has been transferred throughout a cable. Appropriate nodes are using this methodology to make a diagnosis of connection issues, or even just harmful programs to obtain confidential information, like authentication and encryption.Given the variable ip, already declared as a pointer to an integer, write the code to dynamically allocate memory for a single integer value, assign the resulting pointer to ip, and initialize the integer value to 27.
Answer:
In C++:
int *ip;
ip = new int;
*ip = 27;
Explanation:
First of all, let us have a look at the methods of memory allocation to a variable.
1. Compile Time: The memory gets allocated to the variable at the time of compilation of code only. It is also called static allocation of memory.
Code example:
int a = 5;
2. Run Time: The memory is allocated to the variable on the fly i.e. during the execution of the program. It is also called dynamic allocation of memory.
Now, we have to write code for a variable ip, which is an integer pointer to dynamically allocate memory for a single integer value and then initialize the integer value 27 to it.
Initializing a variable means assigning a value to variable for the first time.
Writing the code in C++ programming language:
int *ip; // Declaring the variable ip as a pointer to an integer
ip = new int; // Dynamically allocating memory for a single integer value
*ip = 27; // Initializing the integer value to 27.

Missy loves her old Windows games. When she upgrades her Windows system, the games run fine, but the output looks fuzzy since the programs are designed only to run in VGA mode. What can she do to make the games work properly in Windows
Complete Question:
Missy loves her old Windows games. When she upgrades her Windows system, the games run fine, but the output looks fuzzy since the programs are designed only to run in VGA mode.
Group of answer choices;
A. Reboot into Safe Mode
B. Run compatibility mode for 640 x 480 resolution.
C. Reduce her screen resolution to 640 x480
D. Reboot into Low Resolution Mode
Answer:
B. Run compatibility mode for 640 x 480 resolution.
Explanation:
In this scenario, Missy loves her old Windows games. When she upgrades her Windows system, the games run fine, but the output looks fuzzy since the programs are designed only to run in VGA mode. In order to make the games work properly in Windows, Missy should run compatibility mode for 640 x 480 resolution.
The video graphics array (VGA) is the standard graphics or display interface used for computer monitors. It was developed in 1987 by IBM and it had a standard display resolution of 640 x 480 pixels.
Hence, if the output of a software program (games) looks fuzzy or is not being displayed properly, you should run compatibility mode for 640 x 480 resolution. This is to enable low resolution video mode on the computer.
The VGA mode is very basic because only minimal video drivers are being loaded on the windows.

Which of the following patterns should be used for the delimiter to read one character at a time using a Scanner object's next method? Scanner in = new Scanner(. . .); in.useDelimiter("[^0-9]+"); Scanner in = new Scanner(. . .); in.useDelimiter(""); Scanner in = new Scanner(. . .); in.useDelimiter("[^A-Za-z]+"); Scanner in = new Scanner(. . .); in.useDelimiter("[A-Za-z]+");
Answer:
The method to this question can be defined as follows:
Scanner in = new Scanner(. . .);
in.useDelimiter("");
Explanation:
Following are the code to the question:
import java.util.*; //import package for user input
public class Main //defining class Main
{
public static void main(String ax[])//defining the main method
{
Scanner in = new Scanner("Database");//crearing Scanner class object that pass value in its parameter
in.useDelimiter(""); //using useDelimiter
System.out.println(in.next()); //use print method to print single character value
}
}
Output:
D
Code explanation:
In the above code inside the main method scanner class object "in" is created that pass value "Database" in its parameter. In the next step, useDelimiter is used that uses the scanner class object and single space n its parameter. In the last print, the method is used that prints object value.Page No.:
