What type of attack against a web application uses a newly discovered vulnerability that is not patchable?
A.
Cross-site scripting (XSS)
B.
Structured Query Language (SQL) injection
C.
Zero-day attack
D.
Cross-site request forgery (CSRF)
Answer:
C. Zero-day attack.
Explanation:
A zero-day attack is a type of cyber attack that exploits a vulnerability in software or hardware that is unknown to the party responsible for patching or otherwise protecting the affected system. These attacks can have a significant impact because they take advantage of vulnerabilities that have not yet been discovered or fixed. The term "zero-day" refers to the fact that the attacker is able to take advantage of the vulnerability on the same day that it is discovered, before the vendor has had a chance to develop and distribute a patch to address the issue.
q5. linear programming suppose you are the operations manager for a peanut pro- cessing company, and you need to supply peanuts to two stores: s1 and s2. s1 requires 250 pounds of peanuts, and s2 requires 100 pounds. there are two plants processing peanuts, p1 and p2, and the shipping costs vary: it costs cij to send one pound of peanuts from pi to sj . additionally, p2 can only produce up to 250 pounds of peanuts. formulate an lp (linear program) to determine the most cost-efficient way to supply the two stores with peanuts. 1

If the capacity of a vector named names is 20 and the size of names is 19, which of the following statements are legal?
a) names.push_back("myName");
b) names[18]="myName";
c) All of these
d) None of these
The statement "names.push_back("myName");" is legal as it adds an element to the end of the vector.
The statement "names[18]="myName";" is also legal, as it assigns a value to the 19th index of the vector, which is within the capacity of the vector. Therefore, both of these statements are legal.
To further explore the topic, it's important to understand the differences between the two methods. When using push_back(), the element is added to the end of the vector, and the size of the vector is increased by one. On the other hand, when using the array indexing syntax, the element is inserted into the specified index, and the size of the vector remains the same. It's also important to note that if the index is out of bounds, an error will be thrown, so it's important to check the size of the vector before attempting to insert an element.

Explanation:
Your manager proposed to generate IDs for customers based on what he calls Tribonaci numbers. They define Tribonaci numbers using the recurrence R(i)=R(i−1)+R(i−3), with the first three Tribonaci numbers defined as R(0)=1,R(1)=2,R(2)=2. They would like to assign the i th customer an ID of R(i). You tell them that they are crazy and that the IDs are going to be huge; in fact, you claim that the i th customer will have an ID number of at least 2 i/2. Your manager, who has never taken lightly to criticism, threatens to fire you on the spot unless you can come up with a proof of your claim. (a) To save your job, use induction to prove that in fact R(i)≥2i/2 for all i≥2. (b) Your manager is perplexed. They didn't take CMPSC360 or CMPSC465 so they don't know what induction is and don't understand your proof. They propose a simple recursive algorithm to compute
R(i). The algorithm simply makes the necessary recursive calls and then adds the results. You tell him that his algorithm will take exponential time, but your manager doesn't want to hear anything more about induction. They demand an intuitive picture instead of a proof. Luckily, you just covered something like this in class. Draw a recursion tree that shows the cascade of recursive invocations triggered by a single call to compute R(i). Three levels deep will suffice (i.e. your tree should have 4 levels).
The Fibonacci numbers' generating function is quite similar to the generating function for the tribonaci numbers: n = 0 T n x n = x 1 x x 2 x 3.
What is the formula for Tribonacci numbers?A generalisation of the Fibonacci sequence, the tribonacci series makes each term equal to the sum of the three terms before it. The Tribonacci number has the following general form: a(0) = a(1) = 0, a(2) = 1, and a(n) = a(n-1) + a(n-2) + a(n-3)A Tribonacci sequence or series is a line of numbers where each term, starting with the fourth, equals the sum of the three terms before it. The Tribonacci sequence is defined as T0=0, T1=T2, and T2=1. Tn = (n3) = (n1) + (n2) + (n3).The Fibonacci numbers are determined by the recurrence relation, and the tetranacci numbers are a generalisation of those numbers. With T(0)=0, T(1)=1, T(2)=1, T(3)=2, T(n) = T(n-1) + T(n-2) + T(n-3) + T(n-4) for n >=4.

Do we still use the hard drive for storage on the server or have to opt for SSD? Considering the fact that we now have 10TB + SSD, wouldn't that be better to use SSD?
Answer:
Hard drives are still used for storage on servers in many cases, but SSDs are becoming increasingly popular for server storage due to their higher performance and faster access times. In cases where high performance or fast access times are required, an SSD is the better choice. For example, if you need to store large amounts of data (more than 10TB) on a server, an SSD would be the better choice due to its higher performance and faster access times.

The most efficient method for granting temporary software installation permissions to the sales department would be to add the user account for each employee in the sales department into a special group, then grant temporary software installation permissions to the group. Hence option C is correct.
What is the role of the windows administrator?This method would allow the administrator to easily grant the necessary permissions to all members of the sales department, without having to individually manage permissions for each employee.
Additionally, by using a group, the administrator can easily revoke the permissions if necessary, which would not be possible if each employee was given individual permissions.
Therefore, Granting temporary administrator permissions or local administrator permissions to each employee would not be a secure or efficient method, as it would give each employee full control over their individual computer or the entire network, which could pose a security risk.

A pixel with an R GB value of (255, 0, 0) is red, a pixel with an RGB value of (0, 255, 0) is green, and a pixel with an RGB value of (0, 0, 255) is blue. (255, 255, 255) is white, whereas (0, 0, 0) is black. The eye perceives a broad spectrum of colors when the RGB value of the three color constituents is varied. ASCII encodes characters into binary data of seven bits. Because each bit may be either a 1 or a 0, there are a total of 128 potential possibilities. The value of a pixel in an 8-bit grayscale picture ranging from 0 to 255. A pixel's value at any position corresponds to the intensity of light photons reaching that spot. While 256 characters is enough for expressing English characters, it is significantly too little to carry every character in other languages such as Chinese or Arabic. Unicode uses 16 bits and has a character set of over 65,000 characters. This makes it more appropriate for certain circumstances.

which of the following statements is false? (1 point) everything a computer does is broken down into a series of 0s and 1s. a single bit can represent a single letter. bit is short for binary digit. when referring to computers, every number, letter, or special character consists of a unique combination of 8 bits.
The statement "a single bit can represent a single letter" is false.
Computers store and process information in binary, which means that all data is represented as a series of 0s and 1s. A single bit can only hold a value of either 0 or 1.
To represent more complex information such as letters, numbers, or special characters, multiple bits are combined to form a larger unit of information called a byte. A byte typically consists of 8 bits, and each combination of 8 bits represents a unique character or symbol.
For example, the letter "A" might be represented as the binary number 01000001, while the number "7" might be represented as 00110111.
However, it's important to note that the specific mapping between binary and characters depends on the encoding system used. For example, the ASCII (American Standard Code for Information Interchange) encoding system uses 7 bits to represent each character, while the Unicode encoding system uses a variable number of bits to represent characters from different scripts and symbols from around the world.
In summary, a single bit cannot represent a single letter, number, or special character. Rather, multiple bits are combined to form a byte, which can represent a unique character or symbol.
