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.

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.

A company has only three laptops that connect to their wireless network. The company is currently
using WEP encryption on their wireless network. They have noticed unauthorized connections on
their WAP and want to secure their wireless connection to prevent this. Which of the following
security measures would BEST secure their wireless network? (Select TWO).
A. Change the encryption method to WPA
B. Limit the DHCP scope to only have three addresses total
C. Enable the SSID broadcast
D. Enable and configure MAC filtering
E. Change the broadcast channel to a less commonly used channel
The two security measures that would BEST secure a wireless network, according to the given scenario, are:A. Change the encryption method to WPA.D. Enable and configure MAC filtering because WEP (Wired Equivalent Privacy) is the weakest encryption method of the three (WEP, WPA, WPA2) used for securing a wireless network. So, it is best to replace it with WPA (Wi-Fi Protected Access) or WPA2.
Changing the encryption method to WPA will help to prevent unauthorized connections from accessing the wireless network. The third option, enabling SSID broadcast, will not help in securing the wireless network as it will make the network visible to all devices within the range. So, this option is incorrect.
Now coming to option B, limiting the DHCP scope to three addresses total would mean that the router will only provide three IP addresses, making it difficult to add more devices to the network. This method will only create an inconvenience and will not be useful for securing the network. Therefore, this option is also incorrect.
Now coming to option D, enabling and configuring MAC filtering will prevent unauthorized devices from accessing the network by using the device's MAC address to filter out any device that does not have an authorized MAC address. This is one of the effective security measures to secure a wireless network. So, it is one of the right answers.
Finally, option E, changing the broadcast channel to a less commonly used channel, might help reduce the interference from neighboring networks, but it will not prevent unauthorized access to the network. So, this option is also incorrect.

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.

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.

What device is used to automatically record (write down) changes in temperature?a thermostata thermophilea thermometera thermograph
Option-D: A device that is used to automatically record (write down) changes in temperature is a thermograph.
A thermograph is a device that records temperature over time. It contains a temperature sensor, such as a thermocouple, that is linked to a chart recorder. The chart recorder has a pen that draws a line on a paper chart as it moves across the page, recording the temperature over time. As the temperature fluctuates, the pen moves up and down, resulting in a temperature curve being recorded. Thermographs are utilized in a variety of applications to track temperature changes over time, including environmental monitoring, industrial process control, and weather forecasting.
A thermometer, on the other hand, is a device that measures the temperature of a particular object or environment at a specific moment in time.
A thermostat is a device that is used to control the temperature of a particular space or object by turning a heating or cooling system on and off.
