what is the process by which we can control what parts of a program can acccess the members of class

Answer:

CPU, Program memory, Data memory, Output ports,  Input ports and Clock generator.

Explanation:

There are six basic components of a microcomputer which includes CPU, Program memory, Data memory, Output ports,  Input ports and Clock generator. CPU is the central processing unit which is considered as the brain of the computer. It is the part of a computer that executes instructions. Data memory is the place where data is stored that is present in the CPU.

Answer:

Direct memory access (DMA) is a process that allows an input/output (I/O) device to send or receive data directly to or from the main memory, bypassing the CPU to speed up memory operations and this process is managed by a chip known as a DMA controller (DMAC).

Explanation:

A defined portion of memory is used to send data directly from a peripheral to the motherboard without involving the microprocessor, so that the process does not interfere with overall computer operation.

In older computers, four DMA channels were numbered 0, 1, 2 and 3. When the 16-bit industry standard architecture (ISA) expansion bus was introduced, channels 5, 6 and 7 were added.

ISA was a computer bus standard for IBM-compatible computers, allowing a device to initiate transactions (bus mastering) at a quicker speed. The ISA DMA controller has 8 DMA channels, each one of which associated with a 16-bit address and count registers.

ISA has since been replaced by accelerated graphics port (AGP) and peripheral component interconnect (PCI) expansion cards, which are much faster. Each DMA transfers approximately 2 MB of data per second.

A computer's system resource tools are used for communication between hardware and software. The four types of system resources are:

DMA channels are used to communicate data between the peripheral device and the system memory. All four system resources rely on certain lines on a bus. Some lines on the bus are used for IRQs, some for addresses (the I/O addresses and the memory address) and some for DMA channels.

A DMA channel enables a device to transfer data without exposing the CPU to a work overload. Without the DMA channels, the CPU copies every piece of data using a peripheral bus from the I/O device. Using a peripheral bus occupies the CPU during the read/write process and does not allow other work to be performed until the operation is completed.

With DMA, the CPU can process other tasks while data transfer is being performed. The transfer of data is first initiated by the CPU. The data block can be transferred to and from memory by the DMAC in three ways.

In burst mode, the system bus is released only after the data transfer is completed. In cycle stealing mode, during the transfer of data between the DMA channel and I/O device, the system bus is relinquished for a few clock cycles so that the CPU can perform other tasks. When the data transfer is complete, the CPU receives an interrupt request from the DMA controller. In transparent mode, the DMAC can take charge of the system bus only when it is not required by the processor.

However, using a DMA controller might cause cache coherency problems. The data stored in RAM accessed by the DMA controller may not be updated with the correct cache data if the CPU is using external memory.

Solutions include flushing cache lines before starting outgoing DMA transfers, or performing a cache invalidation on incoming DMA transfers when external writes are signaled to the cache controller.

Answer:

See explanation

Explanation:

DMA [tex]\to[/tex] Direct Memory Access.

The peripherals of a computer system are always in need to communicate with the main memory; it is the duty of the DMA to allow these peripherals to transfer data to and from the memory.

The first step is that the processor starts the DMA controller, then the peripheral is prepared to send or receive the data; lastly, the DMA sends signal when the peripheral is ready to carry out its operation.

Answer and Explanation:

In C programming language:

char fun(int*a, int*b){

printf("enter two integers: ");

scanf("%d%d",a,b);

int e;

printf("please enter a character: ");

e=getchar();

return e;

}

int main(int argc, char *argv[]) {

int d;

int f;

int g;

fun();

printf("%d%d%d", d, f, g);

}

We have declared a function fun type char above and called it in main. Note how he use the getchar function in c which reads the next available character(after the user inputs with printf()) and returns it as an integer. We then return the variable e holding the integer value as char fun() return value.

Answer:

Code:

import java.util.*;  

public class Greetings  

{  

   public static void main(String[] args)  

   {        

       Scanner s = new Scanner(System.in);  

       System.out.println(getGreetings(s));  

   }  

   private static String getGreetings(Scanner console)  

   {          

   System.out.print("Please enter your first name: ");  

   String firstName=console.next();    

   char firstChar=firstName.toUpperCase().charAt(0);  

   System.out.print("Please enter your last name: ");  

   String lastName=console.next();    

   lastName=lastName.toUpperCase().charAt(0)+lastName.substring(1, lastName.length());  

   System.out.print("Please enter your year of birth: ");  

   int year=console.nextInt();  

   int age=getCurrentYear()-year;  

   return "Greetings, "+firstChar+". "+lastName+"! You are about "+age+" years old.";  

   }  

   private static int getCurrentYear()  

   {  

       return Calendar.getInstance().get(Calendar.YEAR);  

   }

Answer:

import pandas as pd

def load_data():

df = pd.read_csv("airline-safety.csv')

num_rows = df.shape[0]

num_cols = df.shape[1]

return df, num_rows, num_cols

Explanation:

Using the pandas python package.

We import the package using the import keyword as pd and we call the pandas methods using the dot(.) notation

pd.read_csv reads the csv data into df variable.

To access the shape of the data which is returned as an array in the format[number of rows, number of columns]

That is ; a data frame with a shape value of [10, 10] has 10 rows and 10 columns.

To access the value of arrays we use square brackets. With values starting with an index of 0 and so on.

The row value is assigned to the variable num_rows and column value assigned to num_cols

Explanation:

The apply method has the axis argument which enables it to use the applied function either across the rows or columns, by passing the value 1 to the axis argument, the mean of at each index is calculated, (across the column) such that the length of the AVG column is equal to the lengtb of the original dataframe.

The drop method is used in pandas to remove row or column entry from a dataframe. To remove columns from a data table, the value 1 is passed to the axis argument of the drop method. Hence, passing 1 to the axis argument removes all 6 columns leaving only the AVG column in result_df.
