(choose all that apply.) a. view columns that are the result of derived values must be given a column alias. b. a constraint name must be provided when using the with check option clause or the statement will fail. c. a view may have column names that are different from the actual base table(s) column names by using column aliases. d. when the view already exists, using the or replace option requires the regranting of the object privileges previously granted on the view.
Answers
The statements concerning the creation of a view are:
a. View columns that are the result of derived values must be given a column alias. This statement is true. When a view column is derived from a calculation or a function, it must be given a column alias, so that the column can be referred to in a SELECT statement.
b. A constraint name must be provided when using the WITH CHECK OPTION clause or the statement will fail.
This statement is true. When using the WITH CHECK OPTION clause in a view, a constraint name must be provided to ensure that any data modifications made through the view conform to the view's filter condition.
c. A view may have column names that are different from the actual base table(s) column names by using column aliases.
This statement is true. When creating a view, column aliases can be used to give the view columns different names than the actual base table columns.
d. When the view already exists, using the OR REPLACE option requires the regranting of the object privileges previously granted on the view.
This statement is true. When using the OR REPLACE option to replace an existing view, the object privileges previously granted on the view must be regranted, since the view is being dropped and recreated.

Which of the following occurs when the icon shown is clicked? A. text is right aligned
B. text is center aligned
C. text is left aligned
D. text is justified
Answers
When the icon shown is clicked, the text is left aligned.
So, the correct answer is C.
This means that the text is positioned along the left margin of the document or text box, with a ragged right edge.
Left alignment is the default text alignment in most programs, and is often used for body text in documents, as it makes it easier to read. The other alignment options available are center, right, and justified.
Center alignment positions text in the center of the document or text box, right alignment positions it along the right margin, and justified alignment spaces the text evenly between the left and right margins, creating a straight edge on both sides.
Hence,the answer of the question is C.

True/false. Humans tend to form mental models that are __________ than reality. Therefore, the closer the __________ model comes to the ___________ model, the easier the program is to use and understand. (3 pts. )
Answers
FALSE. Humans tend to form mental models that simplify and represent reality, but these models are not necessarily "closer" to reality.
Mental models are cognitive constructs that individuals create to understand and interact with the world around them.
While mental models can help us make sense of complex systems or processes, they are subjective interpretations and abstractions rather than direct reflections of reality.
The notion that a closer model leads to easier program use and understanding is not universally true.
In the context of software or user interface design, a mental model that aligns closely with the program's functionality can indeed enhance usability and user experience.
When a program's design and functionality match users' existing mental models or expectations, it can facilitate ease of use and understanding.

how could the seven-segment display driver be designed using a 4-to-16 decoder and logic gates rather than multiplexers?
Answers
A digital combinational logic circuit known as a digital or binary decoder can change one kind of digital code into another.
A particular decoder called a BCD to 7-segment display decoder may change binary coded decimals into a format that can be easily viewed on a 7-segment display. Four binary weighted address inputs (A0 to A3) are decoded to produce sixteen mutually exclusive outputs (Y0 to Y15). The device has two inputs that are input enable (E0 and E1). The outputs are forced to be HIGH when either input is HIGH. In order to break down any combination of inputs into a set of terms that are all set to "0" except for one term, decoders are just a group of logic gates that are organized in a specified fashion.

What is object types in Active Directory?
Answers
Object types in Active Directory are distinct categories of resources or entities that can be managed and organized within the directory service.
Active Directory (AD) is a Microsoft technology used to manage computers, users, groups, and other network resources within an organization. Object types, also known as object classes, are the building blocks of AD, defining the structure and attributes of each item stored in the directory.
Some common object types in Active Directory include:
1. User: Represents an individual user with a unique account, which includes attributes such as username, password, and contact information.
2. Group: A collection of users or other groups that can be granted access to resources, simplifying permission management.
3. Computer: Represents a device connected to the network, allowing administrators to manage its settings and permissions.
4. Organizational Unit (OU): A container for organizing and managing other AD objects, typically used for grouping items by department, function, or location.
5. Group Policy Object (GPO): A set of policies and settings applied to users or computers to maintain security, manage software, and customize the user environment.
Each object type has a specific schema that defines its properties, attributes, and relationships with other object types. Administrators can create custom object types to meet their organization's unique requirements. Overall, object types provide a systematic way to manage and secure the resources within an Active Directory environment.

Explanation:
One of the disadvantages of cable technology is that systems used by many providers require customers to share bandwidth with neighbors. This ultimately causes many problems since cables would need to be extended to reach every single user that will be sharing the bandwidth. This would mean cables all over the place. Also, it is very difficult to limit the bandwidth per person, meaning that if anyone is using up all of the bandwidth through the cable, the rest of the individuals connected would not have the bandwidth that they need or are paying for.

Which of the following most effectively resists a trial-and-error guessing
attack? All sizes are in terms of decimal digits.
Increases the length of the password
A memorized, hard-to-guess password
A passive authentication token with a 9-digit base secret
Answers
To effectively resist a trial-and-error guessing attack, b) increasing the length of the password is the most effective measure.
Increasing the length of the password creates a larger search space for potential combinations, making it more difficult and time-consuming for an attacker to guess the correct password through trial and error.
As the length of the password increases, the number of possible combinations exponentially grows, significantly increasing the computational effort required for an attacker to guess the password.
This is because each additional character in the password multiplies the number of possible combinations an attacker needs to test.
A memorized, hard-to-guess password is also a good security measure, but it may not be as effective as increasing the length of the password alone.
While a hard-to-guess password may require significant computational effort to crack, it is still vulnerable to brute force attacks where an attacker systematically tries all possible combinations.
By increasing the length of the password, even if it is not necessarily hard to guess, the search space becomes exponentially larger, making it more resistant to trial-and-error guessing attacks.
A passive authentication token with a 9-digit base secret may provide an additional layer of security, but its effectiveness depends on various factors, such as the algorithm used, implementation details, and the overall security of the system.
While it adds complexity to the authentication process, it may not be as effective as increasing the length of the password alone.

(Keyboard vs Mouse
Keyboard and mouse are integral parts of a computer system and one cannot even think of interacting with the computer or monitor with the use of these two devices. In a sense, these two devices are the user interface that allows working on a computer system, and without them it is not possible to do anything on a computer. While the main purpose of a mouse is to guide the cursor on the computer monitor, a keyboard is a typewriter like device with some additional functions that allow human interaction with computer. In fact, a keyboard is the only source of providing the input to the computer and it performs the functions we ask it only with the help of this device.
While mouse is considered to be a pointing device, keyboard is the input device for a computer. Despite touch screen having been developed that allows one to use virtual keyboard onscreen, physical keyboard remains first choice of most of the individuals. There are keys with symbols printed on them in a keyboard and with the lightest of touches; the numeral or alphabet gets written on the screen of the monitor using a keyboard. There are some instructions for which one has to press a key and holding it pressed, another key has to be pressed. There are many shortcuts also used with the help of a keyboard that help save time and effort. Many computer commands are the results of these shortcuts. The major function of a keyboard is when one is using a word processor or a text editor.
A mouse is a pointing device and consists of a right and left clicks with a wheel in between that allows on to scroll up and down on a web page. The major function of a mouse is to control the cursor on the monitor of the screen. Today there are wireless mouse available that work through infrared rays.)

Here, the PMT function is used to calculate the monthly payment for a loan.
The arguments required for this function are the interest rate per period, the number of periods, and the present value of the loan.
In this case, the arguments are as follows: Interest rate per period = G5/12Number of periods = G6
Present value of the loan = -G4 (since this value is a negative amount)
Therefore, the complete formula is = PMT(G5/12,G6,-G4).
