Suppose that a 2M x 16 main memory is built using 256kB x 8 RAM chips and memory is word addressable, how many RAM chips are necessary?

Answers

Answer 1

Answer:

16 RAM chips

Explanation:

To calculate the number of RAM chips needed, we divide the total size of the main memory by the size of each RAM chip. Hence:

Number of RAM chips required = Main memory size / size of one RAM

2M = 2²¹, 16 = 2⁴, 256K = 2¹⁸, 8 = 2³

Hence:

Number of RAM chips required = (2²¹ * 2⁴) / (2¹⁸ * 2³) = 2⁴ = 16

Therefore 16 RAM chips are necessary

3. Write a function named sum_of_squares_until that takes one integer as its argument. I will call the argument no_more_than. The function will add up the squares of consecutive integers starting with 1 and stopping when adding one more would make the total go over the no_more_than number provided. The function will RETURN the sum of the squares of those first n integers so long as that sum is less than the limit given by the argument

Answers

Answer:

Following are the program to this question:

def sum_of_squares(no_more_than):#defining a method sum_of_squares that accepts a variable

   i = 1#defining integer variable  

   t = 0#defining integer variable

   while(t+i**2 <= no_more_than):#defining a while loop that checks t+i square value less than equal to parameter value  

       t= t+ i**2#use t variable to add value

       i += 1#increment the value of i by 1

   return t#return t variable value

print(sum_of_squares(12))#defining print method to call sum_of_squares method and print its return value

Output:

5

Explanation:

In the program code, a method "sum_of_squares" is declared, which accepts an integer variable "no_more_than" in its parameter, inside the method, two integer variable "i and t" are declared, in which "i" hold a value 1, and "t" hold a value that is 0.

In the next step, a while loop has defined, that square and add integer value and check its value less than equal to the parameter value, in the loop it checks the value and returns t variable value.

Choose the best answer below:

A. It provides a migration path to IPV6.

B. It permits routing the private IPV4 subnet 10.0.0.0 over the Internet.

C. NAT adds one more bit to the IP address, thus providing more IP addresses to use on the Internet.

D. It allowed SOHO sites to appear as a single IP address, (and single device), to the Internet even though there may be many devices that use IP addresses on the LAN at the SOHO site.

Answer:

NAT helped resolve the shortage of IPV$ addresses after the increase in SOHO, Small Office Home Office sites requiring connections to the internet by:

D. It allowed SOHO sites to appear as a single IP address, (and single device), to the Internet even though there may be many devices that use IP addresses on the LAN at the SOHO site.

Explanation:

Network Address Translation (NAT) gives a router the ability to translate a public IP address to a private IP address and vice versa.  With the added security that it provides to the network, it keeps the private IP addresses hidden (private) from the outside world.  By so doing, NAT permits routers (single devices) to act as agents between the Internet (public networks) and local (private) networks.  With this facilitation, a single unique IP address is required to represent an entire group of computers to anything outside their networks.

check for the common characters within a string and compare them with the other string value.

If there is a match, append it to the array rows.

After iterating over both strings for the substring, get the longest common substring for both strings and print.

Explanation:

The algorithm should create an array that holds the substrings, then use the max function to get the largest or longest substring in the array.

Suppose an application generates chunks 60 bytes of data every 200msec. Assume that each chunk gets put into a TCP packet (using a standard header with no options) and that the TCP packet gets put into an IP packets. What is the % of overhead that is added in because of TCP and IP combines?
1) 40%
2) 10%
3) 20%
4) 70%

Answers

Answer:

1) 40%

Explanation:

Given the data size = 60 byte

data traversed through TSP then IP

Header size of TCP = 20 bytes to 60 bytes

Header size of IP = 20 bytes to 60 bytes

Calculating overhead:

By default minimum header size is taken into consideration hence TCP header size = 20 bytes and IP header size = 20 bytes

Hence, the correct answer is option 1 = 40%

You may not use contains(), startsWith(), endsWith(), split() or related functions. Token-based processing, please.There is no return value.

Answers

Answer:

public static void classSplit(Scanner file){

   int studentsOf21 = 0, studentsOf22 = 0,studentsOf23 = 0, studentsOf24 = 0;

   while (file.hasNext() == true){

       String studentName = file.next();

       int year = file.nextInt();

       switch (year){

           case 2021:

               studentsOf21++;

               break;

           case 2022:

               studentsOf22++;

               break;

           case 2023:

               studentsOf23++;

               break;

           case 2024:

               studentsOf24++;

               break;

       }

   }

   int totalGraduate = studentsOf21+studentsOf22+studentsOf23+studentsOf24;

   System.out.printf("students in class of 2021: %.2f%n", students2021*100.0/totalGraduate);

   System.out.printf("students in class of 2022: %.2f%n", students2022*100.0/totalGraduate);

   System.out.printf("students in class of 2023: %.2f%n", students2023*100.0/totalGraduate);  

   System.out.printf("students in class of 2024: %.2f%n", students2024*100.0/totalGraduate);

}

Explanation:

The classSplit method of the java class accepts a scanner object, split the object by iterating over it to get the text (for names of students) and integer numbers (for graduation year). It does not need a return statement to ask it prints out the percentage of graduates from 2021 to 2024.

Pointers are addresses and have a numerical value. You can print out the value of a pointer as cout << (unsigned)(p). Write a program to compare p, p + 1, q, and q + 1, where p is an int* and q is a double*. Explain the results.

Answers

Answer:

#include <iostream>

using namespace std;

int main() {

  int i = 2;

  double j = 3;

 

  int *p = &i;

  double *q = &j;

 

  cout << "p = " << p << ", p+1 = " << p+1 << endl;

  cout << "q = " << q << ", q+1 = " << q+1 << endl;

  return 0;

}

Explanation:

In C++, pointers are variables or data types that hold the location of another variable in memory. It is denoted by asterisks in between the data type and pointer name during declaration.

The C++ source code above defines two pointers, "p" which is an integer pointer and "q", a double. The reference of the variables i and j are assigned to p and q respectively and the out of the pointers are the location of the i and j values in memory.

Answers

Answer:

SELECT customer_last_name, customer_city, customer_zip FROM customers WHERE customer_state = 'IL' ORDER BY customer_last_name DESC;

Explanation:

Here, we are given a SCHEMA with the table name customers.

It's creation command and commands to insert values are also given.

We have to print the customer last name, city and zip code of all the customers who have their state as IL in the decreasing order of their last names.

Let us learn a few concepts first.

1. To print only a specified number of columns:

We can write the column names to be printed after the SELECT command.

2. To print results as per a condition:

We can use WHERE clause for this purpose.

3. To print in descending order:

We can use ORDER BY clause with the option DESC to fulfill the purpose.

Therefore, the answer to our problem is:

SELECT customer_last_name, customer_city, customer_zip FROM customers WHERE customer_state = 'IL' ORDER BY customer_last_name DESC;

Output of the command is also attached as screenshot in the answer area.

The program is written on 9 lines and the line by line explanation is as follows:

Line 1:

This defines the function

Line 2:

This begins a try except exception that returns an exception if an error is encountered

Line 3:

This open the source file using open and with statement

Line 4:

This open the destination file using open and with statement and also makes it writable

Line 5:

This iterates through the content of the source file; line by line

Line 6:

This writes the content to the destination file

Line 7 & 8:

This is returned if an error is encountered

Line 9:

This prints that the file has been successfully copied        

To call the function from main; use

copy(filename1, filename2)

Where filename1 and filename2 are names of source and destination files.

Take for instance:

filename1 = "test1.txt"

filename1 = "test2.txt"

copy(filename1, filename2)

The above will copy from test1.txt to test2.txt

The function copies text from one file to another. The program written in python 3 goes thus

def copy(filename1, filename2):

#initialize a function names copy and takes two arguments which are two files

try:

#initiate exception to prevent program throwing an error

with open(filename1, "r") as file1 :

#open file1 in the read mode with an alias

with open(filename2, "w") as file2:

#open file 2 in write mode with an alias

for line in file1:

#loop through each line in file 1

file2.write(line)

#copy / write the line in file2

except:

print("Error copying file")

#display if an error is encountered

print("File Copied")

#if no error, display file copied
