Answer:
Management Information System(MIS)
Explanation:
management information system can be regarded as an information system
that is engaged in decision-making as well as the coordination and control and analysis of information in an organization. It involves processes as well as people and technology when studying the management information systems in organizational view.
In Management Information System(MIS) data can be gotten from the database, as well as the compilation of reports, this report could be inventory-level reports,
financial statements/analysis so that routine decision can be made by the manager. It should be noted that Management Information System(MIS) is the Information System (IS) designed to provide reports to managers for tracking operations, monitoring and control.
A file named "games.txt" exists and has 80 lines of data. You open the file with the following line of code.
aFile = open("games.txt", "w")
You write two lines to the file in the program. How many lines are in the file when you close your file?
70
0
73
3
Answer:
2 lines
Explanation:
The "w" flag will overwrite any content, so the existing 80 lines are lost.
Then, if you write two lines, there are two lines in the file.
You could argue that the final newline character causes a third line to be present, but logically, there are two lines.
Assume a large shared LLC that is tiled and distributed on the chip. Assume that the OS page size is 16KB. The entire LLC has a size of 32 MB, uses 64-byte blocks, and is 32-way set-associative. What is the maximum number of tiles such that the OS has full flexibility in placing a page in a tile of its choosing?
Answer:
19 - 22 bits ( maximum number of tiles )
Explanation:
from the given data :
There is 60 k sets ( 6 blocks offset bits , 16 index bits and 18 tag bits )Address has 13-bit page offset and 27 page number bits14-22 bits are used for page number and index bitstherefore any tour of these bits can be used to designate/assign tile number
so the maximum number of tiles such that the OS has full flexibility in placing a page in a tile of its choosing can be between 19 -22 bits

think about system you know,list the parts of the system,describe some ways that the parts are connected to the whole
Answer:
A computer is a complex machine. While most of it works on a microscopic level, it certainly has recognizable macroscopic components that contribute to its uses. A computer can be used to do just about anything from simple calculations to preparing reports to sending rockets into space to simulating the spread of cancer in body organs. Some of the parts are, the motherboard, the power supply, the central processing unit, the optical drive ect. The motherboard plays roles like storing some simple information when the computer is off, such as the system time. The power supply, as you might have already guessed is the powerhouse of the computer. The CPU mainly does arithmetic and logical tasks. It will make a bunch of calculations to ensure the functions of the computer are carried out efficiently. An optical drive is used to read CDs and DVDs, which can be used to listen to music or watch movies. They can also be used to install software, play games, or write new information into a disk.

Analyze and write a comparison of C's malloc and free functions with C++'s new and delete operators. Use safety as the primary consideration in the comparison
Answer:
The C's malloc and free functions and the C++'s new and delete operators execute similar operations but in different ways and return results.
Explanation:
- The new and delete operators return a fully typed pointer while the malloc and free functions return a void pointer.
-The new and delete operators do not return a null value on failure but the malloc/free functions do.
- The new/delete operator memory is allocated from free store while the malloc/free functions allocate from heap.
- The new/delete operators can add a new memory allocator to help with low memory but the malloc/free functions can't.
- The compiler calculates the size of the new/delete operator array while the malloc/free functions manually calculate array size as specified.

Write a loop that subtracts 1 from each element in lowerScores. If the element was already 0 or negative, assign 0 to the element. Ex: lowerScores = {5, 0, 2, -3} becomes {4, 0, 1, 0}.Sample program:#include using namespace std;int main() { const int SCORES_SIZE = 4; vector lowerScores(SCORES_SIZE); int i = 0; lowerScores.at(0) = 5; lowerScores.at(1) = 0; lowerScores.at(2) = 2; lowerScores.at(3) = -3; for (i = 0; i < SCORES_SIZE; ++i) { cout << lowerScores.at(i) << " "; } cout << endl; return 0;}Below, do not type an entire program. Only type the portion indicated by the above instructions (and if a sample program is shown above, only type the portion.)
Answer:
Replace <STUDENT CODE> with
for (i = 0; i < SCORES_SIZE; ++i) {
if(lowerScores.at(i)<=0){
lowerScores.at(i) = 0;
}
else{
lowerScores.at(i) = lowerScores.at(i) - 1;
}
}
Explanation:
To do this, we simply iterate through the vector.
For each item in the vector, we run a check if it is less than 1 (i.e. 0 or negative).
If yes, the vector item is set to 0
If otherwise, 1 is subtracted from that vector item
This line iterates through the vector
for (i = 0; i < SCORES_SIZE; ++i) {
This checks if vector item is less than 1
if(lowerScores.at(i)<1){
If yes, the vector item is set to 0
lowerScores.at(i) = 0;
}
else{
If otherwise, 1 is subtracted from the vector item
lowerScores.at(i) = lowerScores.at(i) - 1;
}
}
Also, include the following at the beginning of the program:
#include <vector>
16. When the speed limit is not posted, the default
speed limit recommends that drivers maintain a
speed of
mph on the highway and
mph in the city.
A. O 65, 40
B. O 60, 35
C. O 55, 30
D. O 50, 25
Answer:
C. 55, 30
Explanation:
Even though each state in the United States has different speed limits. However, in a situation whereby the speed limit is not posted, the default speed limit recommends that drivers maintain a speed of "55" mph on the highway and "30" mph in the city.
The highest speed limit in the United States is 85mph on a rural highway in Texas while the lowest generally for the country is 30mph in a residential area.
An anagram of a string is another string with the same characters in the same frequency, in any order. For example 'ab', 'bca, acb), 'bac', 'cba, 'cab' are all anagrams of the string 'abc'. Given two arrays of strings, for every string in one list, determine how many anagrams of it are in the other list. Write a function that receives dictionary and query, two string arrays. It should return an array of integers where each element i contains the number of anagrams of queryll that exist in dictionary.
Answer:
from collections import Counter
def anagram(dictionary, query):
newList =[]
for element in dictionary:
for item in query:
word = 0
count = 0
for i in [x for x in item]:
if i in element:
count += 1
if count == len(item):
newList.append(item)
ans = list()
for point in Counter(newList).items():
ans.append(point)
print(ans)
mylist = ['jack', 'run', 'contain', 'reserve','hack','mack', 'cantoneese', 'nurse']
setter = ['ack', 'nur', 'can', 'con', 'reeve', 'serve']
anagram(mylist, setter)
Explanation:
The Counter class is used to create a dictionary that counts the number of anagrams in the created list 'newList' and then the counter is looped through to append the items (tuple of key and value pairs) to the 'ans' list which is printed as output.

I just took the test got a 100%
Write a program that teaches arithmetic to a young child. The program tests addition and subtraction. In level 1 it tests only addition of numbers less than 10 whose sum is less than 10. In level 2 it tests addition of arbitrary one-digit numbers. In level 3 it tests subtraction of one-digit numbers with a nonnegative difference. Generate random problems and get the player input. The player gets up to two tries per problem. Advance from one level to the next when the player has achieved a score of five points.
Answer:

cls. score = 0
def end_game(self):
print("Congrats kiddo! You are a math wiz.")
game = Arithmetics()
game. start()
Explanation:
The python class defines the arithmetics class with three-level mathematics for children defined as methods for the class. There are three class methods namely; 'trial_reduce', 'increase_score', and 'init_' with each of them decreasing the trial attribute, increasing the score attribute by one, and initializing the class attributes to its initial state.
The 'end_game' prints a message at the end of the program. Each level is in a loop and counts five times if the answers are correct.

Need help with 4.7 lesson practice edhesive
Answer:
Question 4 => 4th answer: The first line should be for x in range (7, 10):
Question 5 => 2nd answer: 14 16 18 20 22 24 26 28 30 32
Explanation:
Question 4
"for" loops always need a variable (like "x") defined to iterate with different values. for x in range (7, 10): makes x to take values 7, 8, 9 and 10 successively and execute print(x) each time.
Question 5
The expression x in range (7, 16) makes x to take values from 7 up to 16 inclusive. So for each iteration it will execute print x*2 which prints the double of the actual value for x. Starting with x=7, it will print 14, then with x=8 will print 16, and so on. All values are shown on the table below:
X Prints
7 14
8 16
9 18
10 20
11 22
12 24
13 26
14 28
15 30
16 32
The code segments are illustrations of loops.
4: The first line should be for x in range(7,10):5: The output is 14 16 18 20 22 24 26 28 30The syntax of a for loop is:
for variable in range (begin,end+1):
The loop in question (4) is given as:
for range (7,10)
This means that, the variable is missing.
So, the first line of the code segment should be
for x in range(7,10):
For question 5, the value of x would range from 7 to 15.
The print statement prints twice x, followed by a space.
So, the output would be 14 16 18 20 22 24 26 28 30
