Introduction to Royal Malaysia Police.​

Answer:

Programmed I/O, Interrupt Driven I/O, and Direct Memory Access (DMA) are three methods of transferring data between input/output (I/O) devices and the central processing unit (CPU) of a computer system.

Programmed I/O:

In programmed I/O, the CPU executes instructions to transfer data between the I/O device and memory. The CPU continuously polls the I/O device to check if it is ready to send or receive data. This method is simple and easy to implement, but it is also inefficient since the CPU has to wait for the I/O device to be ready before it can perform any other task.

Interrupt Driven I/O:

In interrupt-driven I/O, the CPU sends a command to the I/O device to start the data transfer, and then continues to perform other tasks. When the I/O device has completed the data transfer, it interrupts the CPU to signal that the data is ready. The CPU then stops its current task and processes the interrupt by executing an interrupt service routine (ISR) to transfer the data between the I/O device and memory. This method is more efficient than programmed I/O since the CPU can perform other tasks while waiting for the I/O device to complete the data transfer.

Direct Memory Access (DMA):

In Direct Memory Access (DMA), the I/O device can access the system memory directly without the intervention of the CPU. The I/O device sends a request to the DMA controller to initiate the data transfer, and the DMA controller transfers the data between the I/O device and memory without any involvement of the CPU. The CPU can continue to perform other tasks while the DMA controller performs the data transfer. This method is the most efficient of the three since it frees up the CPU to perform other tasks while the data transfer is being performed.

In summary, the main differences among programmed I/O, interrupt-driven I/O, and DMA are:

Programmed I/O is the simplest method of data transfer, but it is also the least efficient since the CPU has to continuously poll the I/O device to transfer data.

Interrupt-driven I/O is more efficient than programmed I/O since the CPU can perform other tasks while waiting for the I/O device to complete the data transfer.

DMA is the most efficient method of data transfer since it frees up the CPU to perform other tasks while the DMA controller performs the data transfer directly between the I/O device and memory.

The program required to compute the above in Phyton is given below.

the required program is given as follows;

# Input values

litres_per_100km = float(input("Enter the fuel efficiency of your car in litres per 100km: "))

distance_travelled = float(input("Enter the distance travelled in km: "))

cost_per_litre = float(input("Enter the cost per litre of petrol in your local currency: "))

# Calculate the total litres of petrol used

litres_used = (litres_per_100km / 100) * distance_travelled

# Calculate the total cost of the trip

total_cost = litres_used * cost_per_litre

# Display the result

print(f"The total cost of the trip is {total_cost:.2f} {currency_symbol}")



Note that this program prompts the user to enter the fuel efficiency of their car in litres per 100km, the distance travelled in km, and the cost per litre of petrol in their local currency.

It then calculates the total litres of petrol used by multiplying the fuel efficiency by the distance travelled, and calculates the total cost of the trip by multiplying the litres used by the cost per litre.

Finally, it displays the result to the user, rounded to two decimal places. Note that the currency symbol can be added to the output string depending on the user's location.

Divisibility by three is a basic concept in arithmetic that is important to understand for various mathematical operations.

In order to determine if a number is divisible by three, you can use the rule of threes: add up the digits of the number and if the sum is divisible by three, then the original number is also divisible by three.For example, let's consider the number 453. We add the digits together: 4 + 5 + 3 = 12. Since 12 is divisible by three, we know that 453 is also divisible by three.This rule works for larger numbers as well. For instance, consider the number 6,201. Adding the digits gives us: 6 + 2 + 0 + 1 = 9. Since 9 is divisible by three, we can conclude that 6,201 is also divisible by three.Understanding the concept of divisibility by three is important for various mathematical operations such as long division, fractions, and even algebra.

An application-layer message is the data sent between two or more applications. This data can be an email, a voice call, an instant message, a downloadable file, or other type of application-based data. Each application-layer message is divided into one or more packets, which are typically sent via the transport layer of the network.

A transport-layer segment is the packet formed by the Transport layer of the network as it takes the application layer data and transmits it to the Network layer. This packet travels across the network and can be fragmented into multiple segments if it needs to cross a link that has a maximum data size it can handle.

A network-layer datagram is the data unit formed by the Network layer of the network. This datagram is sent to or from the source or destination node and contains information about the route it should take through the network. This layer also performs network-level addressing and routing as the datagram is routed through the network.

A link-layer frame is the smallest data unit sent across a single link in the network. The frame is typically made up of a frame header which contains information about the destination node and link-level addressing and the frame payload which contains the data the link should transport. The frame is then enclosed within a frame check sequence which can be used to detect errors in the frame.

The primary difference between WPA2-Personal and WPA2-Enterprise is in how the authentication process is handled.

WPA2-Personal uses a pre-shared key (PSK) method for authentication, where all users share the same password. This method is suitable for small home networks where there are a limited number of users.

On the other hand, WPA2-Enterprise uses a more complex method of authentication, such as the Extensible Authentication Protocol (EAP), to authenticate each individual user on the network. This method is more suitable for larger organizations with many users, as it provides greater security and control over network access. Additionally, WPA2-Enterprise requires the use of an authentication server, such as a RADIUS server, to manage user authentication.

Answer:

part 1: Adding min as an abstract function to the class arrayListType

We cannot add an abstract function to the class arrayListType directly because it is a concrete class. Instead, we can make the function virtual and assign it a default implementation. Here's how we can do that:

class arrayListType {

public:

   virtual int min() const {

       int min = list[0];

       for (int i = 1; i < length; i++) {

           if (list[i] < min) {

               min = list[i];

           }

       }

       return min;

   }

   // rest of the class definition

};

Here, we made the min function virtual, which means that it can be overridden by derived classes. We also provided a default implementation of the function, which finds the minimum element of the list by iterating over all the elements and comparing them with a variable called min. We start with the first element of the list and update min whenever we find an element that is smaller. Finally, we return min.

part 2: Definition of min in the class unorderedArrayListType

Since the class unorderedArrayListType is derived from the arrayListType class, it inherits the min function. However, we can also override the function in the derived class if we want to provide a different implementation. Here's one way to do that:

class unorderedArrayListType : public arrayListType {

public:

   int min() const override {

       if (length == 0) {

           throw std::logic_error("Cannot find minimum of an empty list");

       }

       int min = list[0];

       for (int i = 1; i < length; i++) {

           if (list[i] < min) {

               min = list[i];

           }

       }

       return min;

   }

   // rest of the class definition

};

Here, we override the min function and provide a new implementation that is similar to the one in the base class, but with an additional check for the length of the list. If the list is empty, we throw an exception to indicate that we cannot find the minimum. Otherwise, we find the minimum in the same way as before.

part 3: A program to test the min function in the class unorderedArrayListType

Here's a sample program that tests the min function in the unorderedArrayListType class:

#include <iostream>

#include "unorderedArrayListType.h"

using namespace std;

int main() {

   unorderedArrayListType list(5);

   list.insertEnd(3);

   list.insertEnd(1);

   list.insertEnd(4);

   list.insertEnd(1);

   list.insertEnd(5);

   cout << "List: ";

   list.print();

   cout << "Minimum: " << list.min() << endl;

   return 0;

}

This program creates an instance of the unorderedArrayListType class with a maximum size of 5 and inserts some elements into the list. Then it prints the list, finds the minimum element using the min function, and prints the result. The output should be:

List: 3 1 4 1 5

Minimum: 1

Answer:

In law, selective enforcement occurs when government officials (such as police officers, prosecutors, or regulators) exercise discretion, which is the power to choose whether or how to punish a person who has violated the law. The biased use of enforcement discretion, such as that based on racial prejudice or corruption, is usually considered a legal abuse and a threat to the rule of law.

In some cases, selective enforcement may be desirable.[1] For example, a verbal warning to a teenager may effectively alter their behavior without resorting to legal punishment and with the added benefit of reducing governmental legal costs. In other cases, selective enforcement may be inevitable. For example, it may be impractical for police officers to issue traffic tickets to every driver they observe exceeding the speed limit, so they may have no choice but to limit action to the most flagrant examples of reckless driving. Therefore, the mere fact that a law is selectively enforced against one person and not against another, absent bias or pattern of enforcement against a constitutionally-protected class, is not illegal.
