What are the constraints for designing small and large files and how these are resolved in different file system
Answer:
space management and buffering speed.
Explanation:
There are different types of file management systems in a computer system, examples of which are NTFS, FAT, WAFL, etc, and are governed by protocols like NFS, TFTP, FTP, etc.
These file systems are used in storages like the hard disk drive, CD and DVD, solid-state drive, etc, to organize or manage the files from boot setup, device drivers to permission-seasoned user files.
Files in storage range from small to large files, for which the schema of the file system must adjust to manage and allocate free space to other files in the future. The file system is also able to index the location of a file for retrieval to a cache memory, making buffering faster.
Write a Visual Basic Program to display factorial series upto nth term 1! 2! 3! 4! ...!
Answer:
n = n(n-1)!
Explanation:
expanding the factorial we get;
1!=1.
2!=2x1.
3!=3x2x1.
4!=4x3x2x1.
5!=5x4x3x2x1.
we can rewrite the above factorials as:
1!=1
2!=2!
3!=2!x3
4!=4x3!
5!=5x4!
the pattern applies such that if we have n th number we get it's factorial as;
n = n(n-1)!
During the data transmission there are chances that the data bits in the frame might get corrupted. This will require the sender to re-transmit the frame and hence it will increase the re-transmission overhead. By considering the scenarios given below, you have to choose whether the packets should be encapsulated in a single frame or multiple frames in order to minimize the re-transmission overhead.
Justify your answer
Scenario A: Suppose you are using a network which is very prone to errors.
Scenario B: Suppose you are using a network with high reliability and accuracy.
1. Based on Scenario A, the packets should be encapsulated in multiple frames to minimize the re-transmission overhead.
This is because there will be the need to re-transmit the packets because the network environment is not reliable and accurate. Therefore, a single frame may be too costly when the need for re-transmission arises.
2. Based on Scenario B, the packets should be encapsulated in a single frame because of the high level of network reliability and accuracy.
There will not be further need to re-transmit the packets in a highly reliable and accurate network environment. This environment makes a single frame better.
Encapsulation involves the process of wrapping code and data together within a class so that data is protected and access to code is restricted.
With encapsulation, each layer:
provides a service to the layer above itcommunicates with a corresponding receiving nodeThus, in a reliable and accurate network environment, single frames should be used to enhance transmission and minimize re-transmission overhead.

5.15 LAB: Count input length without spaces, periods, or commas Given a line of text as input, output the number of characters excluding spaces, periods, or commas. Ex: If the input is:
Answer:
Following are the code to this question:
userVal = input()#defining a variable userVal for input the value
x= 0#defining variable x that holds a value 0
for j in userVal:#defining for loop to count input value in number
if not(j in " .,"):#defining if block that checks there is no spaces,periods,and commas in the value
x += 1#increment the value of x by 1
print(x)#Print x variable value
Output:
Hello, My name is Alex.

Explanation:
In the above-given code, a variable "userVal" is defined that uses the input method for input the value from the user end, in the next line, an integer variable "x" is defined, hold value, that is 0, in this variable, we count all values.
In the next line, for loop is defined that counts string value in number and inside the loop an if block is defined, that uses the not method to remove spaces, periods, and commas from the value and increment the value of x by 1. In the last step, the print method is used, which prints the calculated value of the "x" variable.

Write down the complete AJAX code to avoid page caching.
Answer:
AZAX is key sentence for without reloading page.
Explanation:
AJAX is also known as XHR. If some one wants to send the file without reloading then look ahead at the search function and prompt the users by auto saving the documents. This request is sent to the server. The server return the data to your network. Whenever you have seen the file form, some action on the page. You will see some request from AJAX server request on your functional area. AJAX is called a reloading file without page. AZAX is stands for Asynchronous java scripts And XML.

Explanation:
The intention of this problem is to analyze a user input word, and display the letter that it starts with (book → B).
a. Create a function prototype for a function that accepts a word less than 25 characters long, and return a character.
b. Write the function definition for this function that evaluates the input word and returns the letter that the word starts with in capital letter (if it’s in small letters).
c. Create a function call in the main function, and use the function output to print the following message based on the input from the user. (Remember to have a command prompt in the main function requesting the user to enter any word.)
Computer starts with the letter C.
Summer starts with the letter S.
d. Make sure to consider the case where a naughty user enters characters other than the alphabet to form a word and display a relevant message.
%sb$ is not a word.
$500 is not a word.
e. Have the program process words until it encounters a word beginning with the character
Answer:
Here is the C++ program:
#include<iostream> // to use input output functions
using namespace std; //to identify objects like cin cout
void StartChar(string str) { // function that takes a word string as parameter and returns the first letter of that word in capital
int i;
char c;
do //start of do while loop
{
for (int i = 0; i < str.length(); i++) { //iterates through each character of the word str
if(str.length()>25){ //checks if the length of input word is greater than 25
cout<<"limit exceeded"; } //displays this message if a word is more than 25 characters long
c = str.at(i); // returns the character at position i
if (! ( ( c >= 'a' && c <= 'z' ) || ( c >= 'A' && c <= 'Z' ) ) ) { //checks if the input word is contains characters other than the alphabet
cout<<str<<" is not a word!"<<endl; break;} //displays this message if user enters characters other than the alphabet
if (i == 0) { //check the first character of the input word
str[i]=toupper(str[i]); //converts the first character of the input word to uppercase
cout<<str<<" starts with letter "<<str[i]<<endl; } // prints the letter that the word starts with in capital letter
} cout<<"Enter a word: "; //prompts user to enter a word
cin>>str; //reads input word from user
}while(str!="#"); } //keeps prompting user to enter a word until the user enters #
int main() //start of the main() function body
{ string str; //declares a variable to hold a word
cout<<"Enter a word: "; //prompts user to enter a word
cin>>str; //reads input word from user
StartChar(str); } //calls function passing the word to it
Explanation:
The program prompts the user to enter a word and then calls StartChar(str) method by passing the word to the function.
The function StartChar() takes that word string as argument.
do while loop starts. The for loop inside do while loop iterates through each character of the word string.
First if condition checks if the length of the input word is greater than 25 using length() method which returns the length of the str. For example user inputs "aaaaaaaaaaaaaaaaaaaaaaaaaaa". Then the message limit exceeded is printed on the screen if this if condition evaluates to true.
second if condition checks if the user enters anything except the alphabet character to form a word. For example user $500. If this condition evaluates to true then the message $500 is not a word! is printed on the screen.
Third if condition checks if the first character of input word, convert that character to capital using toupper() method and prints the first letter of the str word in capital. For example if input word is "Computer" then this prints the message: Computer starts with the letter C in the output screen.
The program keeps prompting the user to enter the word until the user enters a hash # to end the program.
The output of the program is attached.
A direct-mapped cache holds 64KB of useful data (not including tag or control bits). Assuming that the block size is 32-byte and the address is 32-bit, find the number of bits needed for tag, index, and byte select fields of the address.
Answer:
A) Number of bits for byte = 6 bits
B) number of bits for index = 17 bits
C) number of bits for tag = 15 bits
Explanation:
Given data :
cache size = 64 kB
block size = 32 -byte
block address = 32 -bit
number of blocks in cache memory
cache size / block size = 64 kb / 32 b = 2^11 hence the number of blocks in cache memory = 11 bits = block offset
A) Number of bits for byte
[tex]log _{2} (6)^2[/tex] = 6 bits
B) number of bits for index
block offset + byte number
= 11 + 6 = 17 bits
c ) number of bits for tag
= 32 - number of bits for index
= 32 - 17 = 15 bits
Why operating system is pivotal in teaching and learning
Answer:
Without it information flow is impossible
Explanation:
The word 'pivotal' also means crucial or vital, and so we need to consider what an operating system actually does.
Remember, merely having all the hardware of a computer would not allow you to run (install and use) programs. It is by means of an operating system that teaching programs can be installed, and it is also by means of an operating system learning can take place.
For example, a student can decode (learn) instructions/lessons from his teacher via a software program; and the software program needs an operating system to open (run) the program.
Assume a client calls an asynchronous RPC to a server, and subsequently waits until the server returns a result using another asynchronous RPC. Is this approach the same as letting the client execute a normal RPC
Answer:
This approach is not the same as letting the client execute a normal RPC
Explanation:
This approach is not the same as letting the client execute a normal RPC and this is because an asynchronous RPC sends an additional message across the network after the initial call/message is sent by the sender to the client. this additional message sent through the network is directed towards the sender of the initial call/message as an acknowledgement of the receipt of the initial message by the client .
synchronous RPC is made of two asychronous RPCs, hence the client executing a normal RPC will not establish a reliable communication between the client and the sender as asynchronous RPC would
Will the Python code below print something? And will it terminate?
def print_n(s, n):
if n > 0:
print(s)
print_n(s, n-1)
return n
n = 3
while print_n("hi", n):
print_n("there!", n)
n = 0
a. no and no
b. yes and no
c. no and yes
d. yes and yes
e. syntax error
Answer:
Yes and Yes
Explanation:
When programs are written without indentation; it becomes a problem to read;
I'll rewrite your program as follows:
def print_n(s, n):
if n > 0:
print(s)
print_n(s, n-1)
return n
n = 3
while print_n("hi", n):
print_n("there!", n)
n = 0
Using the above as a point of reference,
Yes, the program will run and Yes, it'll terminate;
Because n is initialized to 3 at line 6 (where the main starts);
The following is passed to the function; s = "hi" and n=3
This prints "hi", three times
s = "there" and n=3 is then passed to the function print_n, afterwards;
The function then prints "there" three times
Then, the program terminates
Write a recursive function sumSquares(num) that given an integer num, returns the sum of squares of numbers from 1 to num. For example: sumSquares(3) should return 1^2 2^2 3^2
Answer:
Here is the recursive function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num.
def sumSquares(num):
if(num >= 0): # checks if the value of num is less than or equal to 0
if (num==0): #if value of num is 0
return 0 #returns 0 if value of num is 0
else: #if value of num is greater than 0
return sumSquares(num - 1)+ num * num #recursively calls the sumSquares method to return the sum of squares of numbers from 1 to num
else: # if a user enters a negative num
(print("The number if not positive")) #prints this message
exit() # exits after displaying that number if not positive message
#below print statement is used in order to check the working of the function
print(sumSquares(3)) #calls function and passes value 3 for num
Explanation:
The program works as follows:
The function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num
The first if condition checks if value of num is positive. If this condition evaluates to true then the another if statement inside this if statement is executed which checks if the value of num is 0. If this condition evaluates to true then the program returns 0. However if this condition evaluates to false then the else part executes which has the following statement:
return sumSquares(num - 1) + num * num
For example num = 3
so the above recursive statement works as follows:
sumSquares(3-1) + 3 * 3
sumSquares(2) + 9
Note that the sumSquares() method is called again and the value 2 is passed as num. As 2 is greater than 0. So again the recursive statement executes:
sumSquares(2 - 1) + 2 * 2 + 9
sumSquares(1) + 4 + 9
sumSquares(1) + 13
sumSquare() method is called again and the value 1 is passed as num. As 1 is greater than 0. So again the recursive statement executes:
sumSquares(1 - 1) + 1 * 1 + 13
sumSquares(0) + 1 + 13
sumSquares(0) + 14
sumSquare() method is called again and the value 0 is passed as num
As the value of num=0 So the if (num == 0): condition evaluates to true and the statement returns 0 executes which returns 0:
sumSquares(0) + 14
0 + 14
Hence the output is:
14

I'll pick up your question from here:
Define a function print_total_inches, with parameters num_feet and num_inches, that prints the total number of inches. Note: There are 12 inches in a foot.
Sample output with inputs: 5 8
Total inches: 68
Answer:
The program is as follows:
def print_total_inches(num_feet,num_inches):
print("Total Inches: "+str(12 * num_feet + num_inches))
print_total_inches(5,8)
inches = int(input("Inches: "))
feet = int(input("Feet: "))
print_total_inches(feet,inches)
Explanation:
This line defines the function along with the two parameters
def print_total_inches(num_feet,num_inches):
This line calculates and prints the equivalent number of inches
print("Total Inches: "+str(12 * num_feet + num_inches))
The main starts here:
This line tests with the original arguments from the question
print_total_inches(5,8)
The next two lines prompts user for input (inches and feet)
inches = int(input("Inches: "))
feet = int(input("Feet: "))
This line prints the equivalent number of inches depending on the user input
print_total_inches(feet,inches)
Answer:
Written in Python:
def print_total_inches(num_feet,num_inches):
print("Total inches: "+str(12 * num_feet + num_inches))
feet = int(input())
inches = int(input())
print_total_inches(feet, inches)

Write the program to compute how many gallons of paint are needed to cover the given square feet of walls. Assume 1 gallon can cover 350.0 square feet. So gallons =the square feet divided by 350.0. If the input is 250.0, the output should be: 0.714285714286
Answer:
Here is the Python and C++ program.
Python program:
gallons_paint=0.0 #declare and initialize gallons_paint
wall_area = float(input()) #prompts user to enter wall area
gallons_paint = wall_area / 350 #formula to compute gallons of paint needed to cover the given square feet of walls
print(gallons_paint) #display the result
C++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects like cin cout
int main(){ //start of main() function body
float wall_area,gallons_paint=0; //declare variables
cin>>wall_area; //reads input wall area from user
gallons_paint=wall_area/350; //formula to compute gallons of paint needed to cover the given square feet of walls
cout<<gallons_paint;} //print the result
Explanation:
The program prompts the user to enter the area of wall and stores the input value in wall_area
Suppose the user enters 250 as wall area
The the formula gallons_paint=wall_area/350; works as follows:
gallons_paint = wall_area/350;
= 250/350
= 0.71428
gallons_paint = 0.71428
So the output is:
0.71428
