Answer: Program
Explanation:
imagine you need to keep a list of donors for a fundraising event, so that you can send thank-you cards. the 'donor' class has name and address. you know that you will have at most 400 donors and you really don't care what order they are stored in. you aren't going to add more donors later, and the only thing you are going to do is eventually iterate the list and print out address labels. what type of list should you use? group of answer choices a. doubly-linked, sorted list b. arraylist c. sorted list d. singly-linked list
The list that you should use to keep a list of donors for a fundraising event, so that you can send thank-you cards is a type of list called an `arraylist`.
-An `arraylist` should be used when you have an idea of the maximum size of a list and the list is not going to change and you aren't going to add more donors later. -An `ArrayList` is similar to an array, but it has the ability to resize automatically, as you add or remove elements from it. Unlike an array, you don't need to give an `ArrayList` a fixed size when you create it, but you can give it an initial size if you have a good idea of how many elements you will need.-When creating an `ArrayList`, you should specify the type of elements it will contain in angle brackets, like this:ArrayList donorList = new ArrayList();-Then you can add elements to the list using the `add()` method:donorList.add("John Doe");donorList.add("Jane Doe");-To print out the address labels, you can simply iterate over the list using a loop and print out the address for each donor.Learn more about arraylist here: https://brainly.com/question/30752727

scaling of the data should be done individually on training and test data after the split. true false
Scaling of the data should be done on the entire dataset before splitting it into training and test data. The statement "Scaling of the data should be done individually on training and test data after the split" is true.
Why should scaling be performed individually on the training and testing data sets?Scaling is the process of normalizing or standardizing the input data to a machine learning algorithm so that the algorithm can interpret the data more efficiently. The standard scaler is one of the most common methods for scaling data. However, scaling the entire data set at once before the split will cause data leakage.
To prevent data leakage, we must perform scaling separately on the training and testing sets after the split. This is to ensure that our model is tested on new data that has not been used to train the model. When scaling the data for a machine learning algorithm, it is recommended to split the data into training and testing sets, and then scale each set individually.
Therefore, the statement "Scaling of the data should be done individually on training and test data after the split" is true.

What is the process of JPEG 2000?
The process of JPEG 2000 involves compressing a file into a more compact file size without losing the quality of the original file. The process begins by splitting the file into several frequency subbands, which are then further divided into blocks. Each block is then coded using a reversible process to reduce the number of bits necessary to store the data. Finally, the file is encoded using efficient context-based adaptive arithmetic coding.
The process of JPEG 2000 involves the following steps:
Step 1: A DWT (Discrete Wavelet Transform) is applied to the original image to divide it into different layers. As a result of the DWT, four frequency subbands are created, one of which contains the lowest frequency components of the image, and the other three subbands contain increasingly higher frequency components of the image.
Step 2: Quantization is the process of reducing the number of bits used to represent each value in the image data, resulting in a lower-quality image. Quantization involves dividing the data in each subband by a quantization factor.
Step 3: Encoding is the process of converting the quantized image data into a format that can be stored or transmitted. This step is where the actual compression takes place, as the data is encoded in a more efficient way than in the original image file. This encoding process also allows for greater control over the amount of compression that is applied to the image data, which can help to balance the degree of compression with the level of image quality desired.
Step 4: Once the image data has been encoded and compressed, it can be saved as a JPEG 2000 file. When the file is opened, the decoding process takes place, which involves reversing the compression and encoding steps to recreate the original image data. The final result is a compressed image file that is smaller in size than the original file but still retains a high degree of image quality.

Which of the following policies should be adopted to help reduce increasing congestion caused by devices attempting to resend lost packets too quickly or too often?
Retransmission policy
Window policy
Discarding policy
Admission policy
The retransmission policy should be adopted to help reduce the increasing congestion caused by devices attempting to resend lost packets too quickly or too often.
A retransmission policy is a technique that requires the sending of packets until an acknowledgment is received from the receiver. When a packet is sent, it is kept in the queue until an acknowledgment is obtained. If no acknowledgment is obtained, the packet is considered lost and is retransmitted.
This cycle of sending and resending packets causes congestion in the network. As a result, the retransmission policy should be implemented to reduce congestion caused by devices that attempt to resend lost packets too frequently or too quickly.
The issue of too many packets present in the network at the same time, slowing data transmission and affecting the quality of service, is known as congestion. Congestion causes packet loss, slows data transmission, and lowers service quality, which affects the user experience. The following are some common sources of network congestion:
Too much traffic in the network.Failure to keep up with traffic spikes.Network devices' processing power is limited.Poor network design.Packet loss occurs when one or more packets of data traveling through a network do not reach their intended destination. It may be caused by network congestion, poor network design, hardware failure, or packet corruption. When packet loss occurs, the data contained in the packet must be resent, resulting in increased network traffic, delays, and poor service quality.

A systems administrator wants to conduct a scan to identify which services are open on their machines in an attempt to try to disable unused services. Which of the following should they perform?
Question options:
- UDP scan
- NSE scan
- TCP scan
- OS scan
- Ping scan / sweep
The correct answer is To identify which services are open on their machines and disable unused services, the systems administrator should perform a TCP scan.
A TCP scan is a type of port scan that uses the Transmission Control Protocol (TCP) to check whether a port is open or closed. By scanning TCP ports, the systems administrator can identify which services are running on their machines and determine which ones are not being used, allowing them to disable any unnecessary services and improve the security and performance of their system. A UDP scan, on the other hand, is used to identify open User Datagram Protocol (UDP) ports, which are often used for non-critical services that do not require a reliable connection. An NSE (Nmap Scripting Engine) scan is used to gather additional information about the target system, while an OS scan is used to identify the operating system running on the target system. A ping scan/sweep is used to check whether a host is up or down. In summary, the systems administrator should perform a TCP scan to identify which services are open on their machines and disable any unused services to improve the overall security and performance of their system.

Ain) is a special value that cannot be mistaken as a member of a list of data items and signals that there are no more data items to be processed a. terminator b. accumulator c. sentinel d. delimiter
The special value that cannot be mistaken as a member of a list of data items and signals that there are no more data items to be processed is called a sentinel. Therefore, the correct option is option (c).
What's sentinel valueThe sentinel value is normally used to indicate the end of a data sequence. It is a special value that indicates that there are no more data items to be processed, making it distinguishable from the rest of the values.The function of the sentinel value is to avoid the requirement of a counter or an exact count of data items that will be entered.
It allows for the entry of an unknown number of items, hence improving the program's flexibility and user-friendliness.In conclusion, the sentinel value is used to represent the end of the sequence of data items so that the program can know when to stop reading input.

attempting to break a password or encryption through repeated trial and error is called?
The term "brute force attack" refers to the process of making repeated attempts to crack an encryption or password.
A brute force assault involves trying all character combinations until the right one is found in an effort to crack a password or encryption key. Cybercriminals frequently employ this style of attack to obtain unauthorised access to secure systems or sensitive data. Brute force assaults, which can be carried out manually or automatically, can take a lot of time and resources, especially if the passwords or encryption keys are strong and contain a lot of potential combinations. Several security systems use techniques like restricting the number of login attempts, adding pauses between login attempts, or implementing multi-factor authentication to defend against brute force assaults. To stop brute force assaults, it's crucial to utilise encryption keys and strong passwords.

page of 7 zoom cs 280 spring 2023 programming assignment 1 building a lexical analyzer for the spl language february 16, 2023 due date: sunday, march 5, 2023, 23:59 total points: 20 in this programming assignment, you will be building a lexical analyzer for small programming language, called simple perl-like (spl), and a program to test it. this assignment will be followed by two other assignments to build a parser and an interpreter to the spl language. although, we are not concerned about the syntax definitions of the language in this assignment, we intend to introduce it ahead of programming assignment 2 in order to determine the language terminals: reserved words, constants, identifier(s), and operators. the syntax definitions of the spl language are given below using ebnf notations. however, the details of the meanings (i.e. semantics) of the language constructs will be given later on. 1. prog ::
The syntax rules for the SPL language should be defined using EBNF notations.
What is the purpose of creating a lexical analyzer for the SPL language?
The SPL language is a small programming language that requires a lexical analyzer, parser, and interpreter to function. The lexical analyzer is the first component in this process, and its purpose is to analyze the input program and break it down into smaller tokens that can be used by the parser.
The lexical analyzer for the SPL language should be designed to identify and differentiate between different types of tokens, such as keywords, identifiers, constants, and operators. Keywords are reserved words that have a predefined meaning in the SPL language, while identifiers are used to define variable and function names.
Constants in the SPL language can be integer, Boolean, or string literals, and they are used to represent fixed values that do not change during program execution. Operators in the SPL language are used to perform operations on different types of data, such as assignment (=), comparison operators (== and !=), and logical operators (not, or, and).
The extended Backus-Naur form (EBNF) is used to define the syntax rules for the SPL language. The syntax rules define the structure and organization of the language constructs and specify how different tokens can be combined to form valid SPL programs.
In summary, the purpose of creating a lexical analyzer for the SPL language is to break down the input program into smaller tokens that can be used by the parser to generate a parse tree. The lexical analyzer should be designed to identify different types of tokens, such as keywords, identifiers, constants, and operators, and the syntax rules for the SPL language should be defined using EBNF notations.

how to tell if someone blocked your number without texting them
Answer:
It depends based on the application
Explanation:
For example, with WA, their profile picture is removed and you can only see their name. You can't see when they're last online, or if they are online at that moment. If you do decide to send a text, it will only show 1 mark instead of 2. IG will hide the message thread that you have previously had with said person for both of you. On SC, if you search for their username, it won't show up with any results.
