Which result is most likely if a network packet has no header?

2 answers:

8 0

If a network packet has no header it is most likely that the router would have no destination for the payload. The header of the IP packet contains all the necessary information to deliver the packet, including source IP address, destination IP address, length of the packet, version of IP protocol....

So, if the router does not have this information it would not know where to deliver the packet. Correct answer: A

Write a method called classAttendence() that creates a 10-by-10 two-dimensional array and asks for user input to populate it wit

gladu [14]

Answer:

The method written in Java is as follows:

public static void classAttendance(){

Scanner input = new Scanner(System.in);

String[][] names = new String[10][10];

for(int i =0;i<10;i++){

for(int j =0;j<10;j++){

System.out.print("Student Name: "+(i+1)+" , "+(j+1)+": ");

names[i][j] = input.nextLine();

}

Explanation:

This defines the classAttendance() method

public static void classAttendance(){

Scanner input = new Scanner(System.in);

This declares the 2D array of 10 by 10 dimension as string

String[][] names = new String[10][10];

This iterates through the rows of the array

for(int i =0;i<10;i++){

This iterates through the columns of the array

for(int j =0;j<10;j++){

This prompts user for student name

System.out.print("Student Name: "+(i+1)+" , "+(j+1)+": ");

This gets the student name from the user

names[i][j] = input.nextLine();

}

The method ends here

}

More registers appear to be a good thing, in terms of reducing the total number of memory accesses a program might require. Give

gulaghasi [49]

Answer:

Following is given the answer step by step:

Explanation:

First of all we will write a program using MARIE that will support the statement: Sum = (A + B) - (C + D). All the necessary comments are given in front of each statement:

Load A # variable A will be loaded

Add B # B will be added to A

Store Temp1 # A + B will be stored in Temp1

Load C # C will be loaded in memory

Add D # D will be added to C

Store Temp2 # C + D will ge stored in Temp2

Load Temp1 # Temp1 will be loaded in the memory

Subt Temp2 # Temp2(A + B) get subtracted from Temp1(A - B)

Store Sum # (A + B) - (C + D) will get stored in Sum.

We can see from above program that memory is accessed 9 times. While if C + D get executed first than memory accesses will be reduced to 7.

Above same program could be written using an architecture of 4 registers:

The program is as follows:

Load R1 , A #A will be loaded into R1

Load R2 , B # B will be loaded into R2

Add R1 , R2 # R2 gets added to R1 and the result is stored in R1 (A + B)

Load R3 , C # C loaded into R3

Load R4 , D # D loaded into R4

Add R3 , R4 # Value in R4 gets added into R3 and R3 becomes (C + D)

#no memory accesses required for this operation

Subt R1 , R4 #R4 (C + D) gets subtracted from R1 (A + B)

#no memory accesses required for this operation

Store Sum # The recent value will be stored into Sum

Here memory is accessed 5 times in total.
