(Select all that apply).
pre-production
post-production
development
distribution
Explanation:
There are five phases of film production and they include development, pre-production, production, post-production and distribution.
Answer:
pre-production
Explanation:
edg2021
Once the film concept has been developed, the film company transitions to the production phases: pre-production, production, and post-production. In pre-production, the technical details are worked out, a schedule is set, and the resources to produce the film are assembled. This includes casting the film, filling the technical positions, and scheduling the production. The actual filming takes place during the production phase, followed by a post-production phase in which the footage is edited and the final film emerges.
Consider the LIBRARY relational database schema description provided below which is used to keep track of books, borrowers, and book loans. The relations are: • BOOK (BookID, Title, PublisherName) • BOOK_AUTHORS (BookID, AuthorName) • PUBLISHER (Name, Address, Phone) • BOOK_COPIES (BookID, BranchID, NumberOfCopies) • BOOK_LOANS (BookID, BranchID, CardNumber, DateOut, DueDate) • LIBRARY_BRANCH (BranchID, BranchName, Address) • BORROWER (CardNumber, Name, Address, Phone) 1. Consider the schema given above: (a) (5 points) Give a primary key for each relation. Are there any relations for which there is an alternate candidate key that you have not chosen as the primary key? If yes, mention the relations, candidate keys and the reason (if any) for your choice of the primary key. (b) (10 points) State all referential integrity constraints that should hold on these relations.
Answer:
1) Yes, Publisher relation should have a publisherID primary key.
2) NOT NULL and UNIQUE for the BookID, BranchID, CardNumber and name of the borrower in the Book, Book_Copies, Library_branch, and Borrower relations respectively. The DueDate field of the book_loan relation must be a time constraint. The BookID of the Book relation must be serial number for automatic addition and update of bookid across the database.
Explanation:
The Publisher relation should have primary key publisherID which should replace the publisherName in the Book relation to easily make a join query and attain a third-level database model.
In the table below, identify the data type that would be most suitable for the second field.

The surface area of each shape
Triangle
[tex]Area = \frac{1}{2}bh[/tex]
[tex]b\to base; h \to height[/tex]
So:
[tex]Area = \frac{1}{2} * 23 * 21[/tex]
[tex]Area = 241.5m^2[/tex]
Square
[tex]Area = l^2[/tex]
[tex]l \to length[/tex]
So:
[tex]Area = 10^2[/tex]
[tex]Area = 100m^2[/tex]
Rhombus
[tex]Area =a^2\sin(\theta)[/tex]
[tex]a \to side\ length[/tex]
[tex]\theta \to any\ interior\ angle[/tex] (not given)
So:
[tex]Area =18^2\sin(\theta)[/tex]
[tex]Area =324\sin(\theta)[/tex]
Trapezium
[tex]Area = \frac{1}{2}(a + b)*h[/tex]
[tex]a,b \to parallel\ sides; h \to height[/tex]
So:
[tex]Area = \frac{1}{2}(18 + 23)*21[/tex]
[tex]Area = \frac{1}{2}*41*21[/tex]
[tex]Area = 430.5m^2[/tex]
Circle
[tex]Area = \frac{\pi d^2}{4}[/tex]
[tex]d \to diameter[/tex]
So:
[tex]Area = \frac{3.14 * 5^2}{4}[/tex]
[tex]Area = \frac{3.14 * 25}{4}[/tex]
[tex]Area = \frac{78.5}{4}[/tex]
[tex]Area = 19.625m^2[/tex]

Write an expression that evaluates to true if the value of the int variable widthOfBox is not divisible by the value of the int variable widthOfBook. Assume that widthOfBook is not zero. ("Not divisible" means has a remainder.)
Answer:
The expression is:
if widthOfBox % widthOfBook != 0
Explanation:
Given
Variables:
(1) widthOfBox and
(2) widthOfBook
Required
Statement that checks if (1) is divisible by (2)
To do this, we make use of the modulo operator. This checks if (1) is divisible by 2
If the result of the operation is 0, then (1) can be divided by (2)
Else, (1) can not be divided by (2)
From the question, we need the statement to be true if the numbers are not divisible.
So, we make use of the not equal to operator alongside the modulo operator

Minicomputers can be quite bulky. Just the CPU itself can weigh up to 90 pounds.Minis were designed to be less complex than mainframes but still provide multiple terminals for multiple users. However, many of these systems were still slower, had less memory and were unable to integrate into larger networks.
Minicomputers were primarily used for process control and performing financial and administrative tasks, such as word processing and accounting. Some machines were designed for medical laboratory and teaching aids.
Microcomputers are primarily used for word processing, managing databases or spreadsheets, graphics and general office applications.Explanation:

An attacker has obtained the logon credentials for a regular user on your network. Which type of security threat exists if this user account is used to perform administrative functions
Answer:
privilege escalation.
Explanation:
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Hence, an access control list (ACL) primarily is composed of a set of permissions and operations associated with a user account or new technology file system (NTFS) file such as full control, read only, write, read and execute and modify.
In this scenario, an attacker or hacker was able to obtain the logon credentials for a regular user on your network. Thus, the type of security threat which exists if this user account is used by the attacker or hacker to perform administrative functions is privilege escalation.
Privilege escalation can be defined as a network or security threat which involves the exploitation of a design flaw, bug or unsecured configuration settings in a software program (application), operating system (OS), computer system, etc., so as to have an unauthorized access and gain more permissions, elevated rights or privileges that are normally protected from a user account or software program.
Hence, when an attacker or malicious user such as a hacker gains an unauthorized access to the privileges of another user account beyond what is intended or entitled to a user, it is known as privilege escalation.
