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?
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

>>> phrase = "You are amazing!"
>>> _____
'u a'
phrase[3:6]
phrase[2:6]
phrase[3:5]
phrase[2:5]
Answer:
phrase[2:5]
Explanation:
Given:
The above code segment
Required
Which instruction returns 'u a'
First, we need to get the index of u in the phrase:
u is at the third position but in programming, index starts at 0.
So, u is at index 2
Next, we need to get the index of a in the phrase:
a is at index 4
One of the ways to return a sub string from a string in python is [tex]string[start:stop+1][/tex]
Where:
[tex]start = 2[/tex] ----- index of u
[tex]stop = 4[/tex] ----- index of a
phrase ---- The string variable
So, the instruction that returns 'u a' is: [tex]phrase[2:5][/tex]
Where 5 = 4 + 1
Answer:
phrase[2:5]

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%
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%

A substring of some character string is a contiguous sequence of characters in that string (which is different than a subsequence, of course). Suppose you are given two character strings, X and Y , with respective lengths n and m. Describe an efficient algorithm for finding a longest common substring of X and Y .For each algorithm:i. Explain the main idea and approach.Write appropriate pseudo-code.Trace it on at least three different examples, including at least a canonical case and two corner cases.
iv. Give a proof of correctness.v. Give a worst-case asymptotic running time analysis.
Answer:
create a 2-dimensional array, let both rows represent the strings X and Y.
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.

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.
A strictly dominates choice B in a multi-attribute utility. It is in your best interest to choose A no matter which attribute youare optimizing.
a. True
b. False
Answer:
A strictly dominates choice B in a multi-attribute utility. It is in your best interest to choose A no matter which attribute youare optimizing.
a. True
Explanation:
Yes. It is in the best interest to choose option A which dominates choice B. A Multiple Attribute Utility involves evaluating the values of alternatives in order to make preference decisions over the available alternatives. Multiple Attribute Utility decisions are basically characterized by multiple and conflicting attributes. To solve the decision problem, weights are assigned to each attribute. These weights are then used to determine the option that should be prioritized.

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

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
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.

It should be noted that the purpose of black-box testing is to isolate the behavior of a given component of software.
How did NAT help resolve the shortage of IPV4 addresses after the increase in SOHO, Small Office Home Office, sites requiring connections to the Internet?
Question Completion:
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.
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.
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.

Suppose that a t-shirt comes in five sizes: S, M, L, XL, XXL. Each size comes in four colors. How many possible t-shirts are there?
Answer:
120
Explanation:
This question is basically asking how many ways can we arrange 5 sizes of shirts if they come in 4 colors.
5 permutation of 4
To find permutation, we use the formula
P(n, r) = n! / (n - r)!
Where
n is the size of the shirts available, 5
r is the color of each shirt available, 4
P(5, 4) = 5! / (5 - 4)!
P(5, 4) = (5 * 4 * 3 * 2 * 1) / 1!
P(5, 4) = 120 / 1
P(5, 4) = 120
Therefore, the total number of shirts available is 120

What line of code makes the character pointer studentPointer point to the character variable userStudent?char userStudent = 'S';char* studentPointer;
Answer:
char* studentPointer = &userStudent;
Explanation:
Pointers in C are variables used to point to the location of another variable. To declare pointer, the data type must be specified (same as the variable it is pointing to), followed by an asterisk and then the name of the pointer. The reference of the target variable is also assigned to the pointer to allow direct changes from the pointer variable.
