for each type of i/o, briefly explain its uniqueness: programmed i/o interrupt-driven i/o direct memory access (dma)?

Answers

Answer 1

Answer:

Programmed I/O refers to the method where the processor is responsible for manually controlling the transfer of data to or from a device. In this method, the processor waits for the input or output operation to be completed before moving on to the next task.

In interrupt-driven I/O, the device itself notifies the processor when it is ready for input or output operations. This method reduces the amount of waiting time for the processor since it can continue executing other tasks while waiting for the device to complete.

Direct Memory Access (DMA) is a technique that allows devices to transfer data to or from memory without involving the processor. This method is used to reduce the burden on the processor and speed up the data transfer process. The DMA controller takes over the bus and directly transfers data between the device and memory. During this process, the processor is free to perform other tasks, increasing overall system performance.

Answers

The DNS poisoning technique used by an attacker to infect a victim's machine with a trojan and remotely change their DNS IP address to that of the attacker's is Internet DNS spoofing.

Internet DNS spoofing, also known as DNS hijacking, is a type of attack in which an attacker intercepts the victim's DNS traffic and redirects them to a malicious DNS server. The malicious DNS server then responds to the victim's DNS requests with false IP addresses, redirecting the victim's traffic to the attacker's desired destination. This technique can be used by attackers to infect the victim's machine with malware or to steal sensitive information. To protect against Internet DNS spoofing, it is recommended to use DNSSEC, which provides a secure means of verifying the authenticity of DNS data.

Which of the following type of vulnerability scan can also attempt to exploit the vulnerabilities? Non-credentialed Non-intrusive Intrusive Credentialed

Answers

The type of vulnerability scan that can also attempt to exploit vulnerabilities is "Intrusive."

Intrusive vulnerability scans are a type of security assessment that not only identifies vulnerabilities but also attempts to exploit them. These scans simulate real-world attack scenarios to determine the extent of the vulnerability and assess the potential impact of an actual exploit.

During an intrusive vulnerability scan, the scanning tool actively probes the target system by sending various types of malicious payloads, executing commands, or attempting unauthorized access. The goal is to test the system's defenses and identify potential weaknesses that could be exploited by an attacker.

By attempting to exploit vulnerabilities, intrusive scans provide more comprehensive results compared to non-intrusive scans. They help uncover hidden vulnerabilities that might not be detected through passive scanning techniques. However, it's important to note that intrusive scans carry certain risks, as they can potentially disrupt system operations or cause unintended consequences. Therefore, they should be conducted with caution and only in controlled environments with proper authorization.

In contrast, non-credentialed scans do not require any login credentials or privileged access to the target system. Non-intrusive scans focus on identifying vulnerabilities from an external perspective without actively attempting to exploit them. Credentialed scans, on the other hand, require valid login credentials and provide deeper insight into the system's security posture by assessing vulnerabilities from an internal perspective.

It is easier to organize data and retrieve it when there is little or no dependence between programs and data. Why is there more dependence in a file approach and less in the database approach?

Answers

In a file approach, there is more dependence between programs and data, while in a database approach, there is less dependence.

This is because the file approach stores data in separate files specific to each program, leading to tight coupling between programs and their corresponding data. In contrast, the database approach utilizes a centralized database system that allows data to be shared and accessed by multiple programs, reducing dependence and enabling easier organization and retrieval of data.

The file approach involves storing data in individual files associated with specific programs. Each program is responsible for managing its own data files, resulting in a high degree of dependence between programs and data. If multiple programs need access to the same data, they would have to duplicate and maintain separate copies of the data, leading to redundancy and potential inconsistency issues. This tight coupling between programs and their specific data files makes it more challenging to organize and retrieve data efficiently.
On the other hand, the database approach utilizes a centralized database system that provides a shared repository for storing and managing data. The database is designed to handle multiple applications or programs, allowing them to access and manipulate data as needed. This centralized approach reduces dependence by decoupling programs from the specific organization and storage of data. Programs can interact with the database through standardized interfaces, such as SQL, which abstracts the underlying data storage details. This abstraction enables easier organization and retrieval of data, as programs can access and retrieve data from the database without having to directly manage individual files. Overall, the database approach promotes data independence and facilitates better organization and retrieval of data compared to the file approach.

Answers

To develop a system that reads character values from the user and store them in a 2D array of size [2][3], and then find how many times the letter ‘a’ occurred and print the 2D array as a matrix, we can use the following code:```#include
#include

int main()
{
   char arr[2][3];
   int i, j, count = 0;

   for(i=0; i<2; i++)
   {
       for(j=0; j<3; j++)
       {
           printf("Enter a character: ");
           scanf(" %c", &arr[i][j]);
           if(arr[i][j] == 'a' || arr[i][j] == 'A')
              count++;
       }
   }

   printf("\nThe 2D array as a matrix is:\n");

   for(i=0; i<2; i++)
   {
       for(j=0; j<3; j++)
       {
           printf("%c ", arr[i][j]);
       }
       printf("\n");
   }

   printf("\nThe letter 'a' occurred %d times in the 2D array.", count);

   return 0;


}```Here, we have declared a 2D array of size [2][3] to store the character values entered by the user. We have used two for loops to iterate over the array and read the character values entered by the user. We have also used a counter variable to count the number of times the letter 'a' occurred in the array.Once we have read all the character values, we print the 2D array as a matrix using another set of for loops. Finally, we print the number of times the letter 'a' occurred in the array.
