Answer:
A. 9
B. 16
C. Number of addresses = 12 number of data lines = 16
Explanation:
The capacity of this chip is 512 x 8
That is 512 words and these words have 8 bits
A. The number of the address lines would be
log2(512) = 2⁹
So the answer is 9
B. The total number of chips required
= 512 x 8 = 4096
(4096 x 2)/ 512 = 16
C. Number of address = log4092 = 2¹²
= 12
The number of data lines = 8x2 = 16
Thank you!
As of Spring 2020, in otder to get into the CS major, you must have a 3.0 GPA or better in cs120, cs210, and cs245. In this problem, you should write one function named get_gpa, which will calculate this GPA. This function should have one parameter, which will be a dictionary of grades in computer science courses. You can assume that the dictionary will always have the keys 'cs120', 'cs210', and 'cs245', but it also might contain some names of other courses too. The values associated with each key will be a float representeing the GPA-style grade for that class. For instance, the parameter dictionary might look like: {'cs120':4.0 'cs245':3.0, 'cs210':2.0}. Some examples:
get_gpa({'cs110': 4.0, 'cs245':3.0, 'cs335':4.0, 'cs120':3.0, 'cs210':3.0}) should return 3.0.
get_gpa({'cs110': 4.0, 'cs120':3.0, 'cs245':2.0, 'cs210':1.0}) should return 2.0.
get_gpa({'cs245':4.0, 'cs120':3.0, 'cs245':2.0}) should return 3.0.
Make sure to include only the one function in your file.
Answer:
The function is as follows:
def get_gpa(mydict):
gpa = 0
kount = 0
for course_code, gp in mydict.items():
if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':
gpa += float(gp)
kount+=1
return (gpa/kount)
Explanation:
This defines the function
def get_gpa(mydict):
This initializes gpa to 0
gpa = 0
This initializes kount to 0
kount = 0
This iterates through the courses
for course_code, gp in mydict.items():
If course code is cs120 or cs210 or cs245
if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':
The gpa is added
gpa += float(gp)
And the number of courses is increased by 1
kount+=1
This returns the gpa
return (gpa/kount)

Suppose a byte-addressable computer using set-associative cache has 2 16 bytes of main memory and a cache size of 32 blocks and each cache block contains 8 bytes. a) If this cache is 2-way set associative, what is the format of a memory address as seen by the cache; that is, what are the size of the tag, set, and offset fields
Answer:
Following are the responses to these question:
Explanation:
The cache size is 2n words whenever the address bit number is n then So, because cache size is 216 words, its number of address bits required for that cache is 16 because the recollection is relational 2, there is 2 type for each set. Its cache has 32 blocks, so overall sets are as follows:
[tex]\text{Total Number of sets raluired}= \frac{\text{Number of blocks}}{Associativity}[/tex]
[tex]=\frac{32}{2}\\\\ =16\\\\= 2^4 \ sets[/tex]
The set bits required also are 4. Therefore.
Every other block has 8 words, 23 words, so the field of the word requires 3 bits.
For both the tag field, the remaining portion bits are essential. The bytes in the tag field are calculated as follows:
Bits number in the field tag =Address Bits Total number-Set bits number number-Number of bits of words
=16-4-3
= 9 bit
The number of bits inside the individual fields is therefore as follows:
Tag field: 8 bits Tag field
Fieldset: 4 bits
Field Word:3 bits
The keyboard shortcut to enter the current date in a field is

Ctrl+ampersand (&)
Ctrl+asterisk (*)

Answer:
10
Explanation:
[tex]sum(1,2) = 3\\sum(3,4) = 7\\sum(3,7) = 10\\[/tex]
Basically, sum((1+2) + (3+4)) = sum(3,7) = (3+7) = 10

HLOOKUP is used for Horizontal Data look ups while VLOOKUP is for Vertical Data look ups
Select one:
True
False
Answer:
True
Explanation:
Both HLOOKUP and VLOOKUP are excel functions used for searching through tables for a specified lookup value to either get an exact or approximate match. The VLOOK and HLOOKUP functions have identical syntax which only differs with the HLOOKUP requiring the row index number to search through the rows while, VLOOKUP requires the column index number to search through the columns. Other than this difference, the other syntax values are the same.
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])
Create a map using the Java map collection. The map should have 4 entries representing students. Each entry should have a unique student ID for the key and a student name for the element value. The map content can be coded in directly, you do not have to allow a user to enter the map data. Your program will display both the key and the value of each element.
Answer:
In Java:
import java.util.*;
public class Main{
public static void main(String[] args) {
Map<String, String> students = new HashMap<>();
students.put("STUD1", "Student 1 Name");
students.put("STUD2", "Student 2 Name");
students.put("STUD3", "Student 3 Name");
students.put("STUD4", "Student 4 Name");
for(Map.Entry m:students.entrySet()){
System.out.println(m.getKey()+" - "+m.getValue()); }
}}
Explanation:
This creates the map named students
Map<String, String> students = new HashMap<>();
The next four lines populates the map with the ID and name of the 4 students
students.put("STUD1", "Student 1 Name");
students.put("STUD2", "Student 2 Name");
students.put("STUD3", "Student 3 Name");
students.put("STUD4", "Student 4 Name");
This iterates through the map
for(Map.Entry m:students.entrySet()){
This prints the details of each student
System.out.println(m.getKey()+" - "+m.getValue()); }

The derived class Dog extends the Pet class and includes a private data member for dogBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Dog pet, use PrintInfo() to print information, and add a statement to print the dog's breed using the GetBreed() function.
Answer:
Answered below.
Explanation:
//Program in Java
Class Test{
public static void main (String[] args){
//create a pet object
Pet pet = new Pet();
//call pet object's printInfo method
pet.printInfo();
//create a new Dog object
Dog dog = new Dog();
//dog can access the printInfo method of the Pet class because it derives from it
dog.printInfo();
//dog can also call it's private method.
dog.getBreed();

I run an online e-commerce store and lately its been very difficult keeping track of customer detail, incoming orders, keyword generation etc. One solution that I thought about would be an application that controls all of that for me. In order to accomplish this I would first need to design and create a GUI that contains all of the necessary buttons and displays for the information. Then I would need to code a webscraper using Python to grab all of the data from e-commerce store as soon as it becomes available, organize it, and display it within the GUI.
Summary
In this lab, you use what you have learned about searching an array to find an exact match to complete a partially prewritten C++ program. The program uses an array that contains valid names for 10 cities in Michigan. You ask the user to enter a city name; your program then searches the array for that city name. If it is not found, the program should print a message that informs the user the city name is not found in the list of valid cities in Michigan.
The file provided for this lab includes the input statements and the necessary variable declarations. You need to use a loop to examine all the items in the array and test for a match. You also need to set a flag if there is a match and then test the flag variable to determine if you should print the the Not a city in Michigan.message. Comments in the code tell you where to write your statements. You can use the previous Mail Order program as a guide.
Instructions
Ensure the provided code file named MichiganCities.cppis open.
Study the prewritten code to make sure you understand it.
Write a loop statement that examines the names of cities stored in the array.
Write code that tests for a match.
Write code that, when appropriate, prints the message Not a city in Michigan..
Execute the program by clicking the Run button at the bottom of the screen. Use the following as input:
Chicago
Brooklyn
Watervliet
Acme
// MichiganCities.cpp - This program prints a message for invalid cities in Michigan.
// Input: Interactive
// Output: Error message or nothing
#include
#include
using namespace std;
int main()
{
// Declare variables
string inCity; // name of city to look up in array
const int NUM_CITIES = 10;
// Initialized array of cities
string citiesInMichigan[] = {"Acme", "Albion", "Detroit", "Watervliet", "Coloma", "Saginaw", "Richland", "Glenn", "Midland", "Brooklyn"};
bool foundIt = false; // Flag variable
int x; // Loop control variable
// Get user input
cout << "Enter name of city: ";
cin >> inCity;
// Write your loop here
// Write your test statement here to see if there is
// a match. Set the flag to true if city is found.
// Test to see if city was not found to determine if
// "Not a city in Michigan" message should be printed.
return 0;
} // End of main()
Answer:
Replace the comments with:
for(x = 0; x < NUM_CITIES; x++){
if(inCity == citiesInMichigan[x]){ foundIt = true;}
}
if(foundIt){ cout<<"Exists";}
else{cout<<"Does not exists";}
Explanation:
This iterates through the cities
[tex]for(x = 0; x < NUM\_CITIES; x++)\{[/tex]
This checks if current city in the array matches the city input by the user
[tex]if(inCity == citie sIn Michigan[x])\{[/tex] foundIt = true; If yes, foundIt is set to true}
}
If foundIt is true, print "Exists"
if(foundIt){ cout<<"Exists";}
If foundIt is false, print "Does not Exists"
else{cout<<"Does not exists";}
