A digital computer has a memory unit with 16 bits per word. The instruction set consists of 72 different operations. All instructions have an operation code part(opcode) and an address part(allowing for only one address). Each instruction is stored in one word of memory.
Required:
a. How many bits are needed for the opcode?
b. How many bits are left for the address part of the instruction?
c. What is the maximum allowable size for memory?
d. What is the largest unsigned binary number that can be accommodated in one word of memory?
Answer:
a. 7 bits b. 9 bits c. 1 kB d. 2¹⁶ - 1
Explanation:
a. How many bits are needed for the opcode?
Since there are 72 different operations, we require the number of bits that would contain 72 different operations. So, 2ⁿ ≥ 72
72 = 64 + 8 = 2⁶ + 8
Since n must be an integer value, the closest value of n that would contain 72 different operations is n = 7. So, 2⁷ = 128
So, we require 7 bits for the opcode.
b. How many bits are left for the address part of the instruction?
bits left = bits per word - opcode bit = 16 - 7 = 9 bits
c. What is the maximum allowable size for memory?
Since there are going to be 2⁹ bits to addresses each word and 16 bits for each word, the maximum allowable size for memory is thus 2⁹ × 16 = 512 × 16 = 8192 bits.
We convert this to bytes
8192 bits × 1 byte/8 bits = 1024 bytes = 1 kB
d. What is the largest unsigned binary number that can be accommodated in one word of memory?
Since the number go from 0 to 2¹⁶, the largest unsigned binary number that can be accommodated in one word of memory is thus
2¹⁶ - 1
Construct a SQL query that displays a list of colleges, their sity/state, the accrediting agency, and whether or not the school is distance only. Only show the first 10 records.
Answer:
SELECT college, city_state, accre_agency, distance LIMIT 10
Explanation:
Given
Table name: College
See attachment for table
Required
Retrieve top 10 college, state, agency and school distance from the table
To retrieve from a table, we make use of the SELECT query
The select statement is then followed by the columns to be selected (separated by comma (,))
So, we have:
SELECT college, city_state, accre_agency, distance
From the question, we are to select only first 10 records.
This is achieved using the LIMIT clause
i.e. LIMIT 10 for first 10
So, the complete query is:
SELECT college, city_state, accre_agency, distance LIMIT 10
Let ∑ = {a,b}, and let L be the language over ∑:
L ={ w € ∑+ |w is even, and w contains at least one a in the first half and exactly one b in the second half }
Give a context-free grammar (CFG) for L, and briefly explain how it works to correctly represent the language. There are no additional requirements for your solution other than what is stated here, except the usual guidance to make sure your answer is clear and understandable and avoids too much unnecessary complexity. In particular, there is no credit for the grammar being unambiguous (if possible.)
Answer:
Explanation:
From the information given, By applying a CFG for L:
Because each state generates two symbols or null, the length will be equal and even.
1st Condition:throughout the first half, at least one (a)
2nd:exactly one (b) within the second half

Newton's method has the advantage of having a faster quadratic convergence rate over the other methods such as Secant and bisection methods.
a. True
b. False
Answer:
a. True
Explanation:
The Newton's method (Newton-Raphson method) used in advanced statistical computing can be used for a continuous and differentiable function that can be approximated by a straight line tangent to it. It requires the derivative of the function to be known, Newton's method converges faster that is whenever it converges. Newton Raphson Method has quadratic convergence which is faster, and the quadratic convergence makes the error in the next iteration increase by the square of the value of the previous iteration.

Suppose that you are asked to modify the Stack class to add a new operation max() that returns the current maximum of the stack comparable objects. Assume that pop and push operations are currently implemented using array a as follows, where item is a String and n is the size of the stack. Note: if x andy are objects of the same type, use x.compareTo(y) to compare the objects x and y public void push String item ) { [n++] = iten; } public String pop { return al--n]; } Implement the max operation in two ways, by writing a new method using array a (in 8.1), or updating push and pop methods to track max as the stack is changed (in 8.2). Q8.1 Implement method maxi 5 Points Write a method max() using Out) space and Oin) running time. public String max() {...} Enter your answer here Q8.2 Update push() and popo 5 Points Write a method max() using On) space and 011) run time. You may update the push and pop methods as needed public void push {...} public String pop() {...} public String max() {...}
Answer:
Following are the code to the given points:
Explanation:
For point 8.1:
public String max()//defining a method max
{
String maxVal=null;//defining a string variable that holds a value
for(int x=0;x<n;x++)
{
if(maxVal==null || a[i].compareTo(maxVal)>0)//defining if blok to comare the value
{
maxVal=a[i];//holding value in maxVal variable
}
}
return maxVal;//return maxVal variable value
}
For point 8.2:
public void push(String item)//defining a method push that accepts item value in a parameter
{
a[n]=item;//defining an array to hold item value
if(n==0 || item.compareTo(maxVals[n-1])>0)//use if to comare item value
{
maxVals[n]=item;//holding item value in maxVals variable
}
else
{
maxVals[n]=maxVals[n-1];//decreasing the maxVals value
}
n++;//incrementing n value
}
public String pop()//defining a method pop
{
return a[--n];//use return value
}
public String max()//defining a method max
{
return maxVals[n-1];//return max value
}
In the first point, the max method is declared that compares the string and returns its max value.In the second point, the push, pop, and max method are declared that works with their respective names like insert, remove and find max and after that, they return its value.Assume that Student, Employee and Retired are all extended classes of Person, and all four classes have different implementations of the method getMoney. Consider the following code where_______ indicates the required parameters for the constructors:
Person p = new Person(...);
int m1 = p.getMoney(); // assignment 1
p = new Student(...);
int m2 = p.getMoney(); // assignment 2
if (m2 < 100000)
p = new Employee(...);
else if (m1 > 50000)
p = new Retired(...);
int m3 = p.getMoney(); // assignment 3
Refer to above code The reference to getMoney() in assignment 1 is to the class:________
a. Person
b. Student
c. Employee
d. Retired
e. This cannot be determined by examining the code
Answer:
a. Person
Explanation:
The reference getMoney() is a method that is part of the Person class. This can be proven with the code since subclasses can access methods from the parent class but a parent class cannot access methods from the child classes. Since Student, Employee, and Retired are all child classes that extend to the Person parent class then they can access getMoney(), but unless getMoney() is in the Person class, then a Person object shouldn't be able to access it. Since the first object created is a Person object and it is accessing the getMoney() method, then we can assume that the getMoney() method is within the Person class.
The following implementations of the method reverse are intended to reverse the o rder of the elements in a LinkedList.
I.

IlI.
public static void reverse (LinkedList alist) while (aList.size ()>0) while (Itemp.isEmpty()) Stack temp new Stack ( temp.push (aList.removeLast ()) aList.addFirst (temp.pop ());
Which of the choices above perform the intended task successfully? Why?
a. I only
b. Il only
c. Ill only
d. Il and Ill only
e. I, ll, and IlI
Answer:

Explanation:
All of the code snippets provided are missing small details such as brackets in the correct places and '=' to signal an assignment. These are crucial when coding in Java and the code will not run without it. Regardless, the only implementation that is correct in the options would be implementation III. It is the only code snippet that is correctly structured to reverse the order of the elements. It will still need debugging in order to get it to work.

Suppose data is available for an on-line music distributor. This data includes: song title, artist performing the song, date song purchased, amount charged for the song. Using only the information available in the distributor's data (song title, artist performing, date purchased, amount charged), which of the following can be determined using database or spreadsheet software?
a. The number of songs by a particular artist that were purchased on a given date.
b. The amount of money charged on the first day of any given month.
c. Whether the amount charged is the same for each song title.
Answer:
The answer is "Option a".
Explanation:
In this question, the only choice "a" is correct because in the question it is declared that it includes: your track title, the performance artist, the date their track is bought, the fee for the track. Its number of music purchased by a given artist on a particular date is based only on details available on the distributor's song title, performing, date purchased, the sum paid.

In the following cell, we've loaded the text of Pride and Prejudice by Jane Austen, split it into individual words, and stored these words in an array p_and_p_words. Using a for loop, assign longer_than_five to the number of words in the novel that are more than 5 letters long. Hint: You can find the number of letters in a word with the len function.
Answer:
Explanation:
Since the array is not provided, I created a Python function that takes in the array and loops through it counting all of the words that are longer than 5. Then it returns the variable longer_than_five. To test this function I created an array of words based on the synapse of Pride and Prejudice. The output can be seen in the attached picture below.
def countWords(p_and_p_words):
longer_than_five = 0
for word in p_and_p_words:
if len(word) > 5:
longer_than_five += 1
return longer_than_five

Write a while loop that prints user_num divided by 2 until user_num is less than 1. The value of user_num changes inside of the loop.
Sample output with input: 20
10.0
5.0
2.5
1.25
0.625
Note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds and report "Program end never reached." The system doesn't print the test case that caused the reported message.
My code, it only passes one test with correct outputs
what am I forgetting?
You're setting the value of user_num to 20. Doing this won't allow the other test cases to run. Simply delete that line and your code should work. This is the code I wrote:
user_num = int(input())
while user_num>=1:
user_num/=2
print(user_num)

Answer:
It throws an error.
the public class needs a name.
like this:
public class G{ public static void main(String[] args) {
int x=5 , y = 10;
if (x>5 && y>=2) System.out.println("Class 1");
else if (x<14 || y>5) System.out.println(" Class 2");
else System.out.println(" Class 3"); }// end of main
}
if you give the class a name and format it, you get:
Class 2

By the 1970s, the acceleration of airplane travel led to fears that an epidemic would leapfrog the globe much faster than the pandemics of the Middle Ages, fears that were confirmed beginning in the 1970s by the worldwide spread of:________
a. the Zika virus.
b. the HIV infection
c. severe acute respiratory syndrome (SARS)
d. the Asian flu virus
e. Ebola
Answer:
b. the HIV infection.
Explanation:
Around the 1970s, an increase in the use of airplane travel led to fears that an epidemic would leapfrog the globe much faster than the pandemics such as tuberculosis, leprosy, smallpox, trachoma, anthrax, scabies, etc., that were evident during the Middle Ages, fears that were later confirmed by the worldwide spread of the HIV infection, beginning in the 1970s in the United States of America.
STD is an acronym for sexually transmitted disease and it can be defined as diseases that are easily transmissible or contractable from another person through sexual intercourse. Thus, STD spread from an infected person to an uninfected person while engaging in unprotected sexual intercourse. Some examples of STDs are gonorrhea, chlamydia, syphilis, HIV, etc.
HIV is an acronym for human immunodeficiency virus and it refers to a type of disease that destabilizes or destroy the immune system of a person, thus, making it impossible for antigens to effectively fight pathogens.
Generally, contracting STDs has a detrimental effect to a patient because it causes an opening (break) or sore in the body of the carrier (patient) and as such making them vulnerable to diseases that are spread through bodily fluids e.g human immunodeficiency virus (HIV), Hepatitis, staphylococcus, AIDS, etc.
Another method that might be desired is one that updates the Goalie's jerseyNumber. This method will receive a new number of Jersey and set this number to the Goalie's current jerseyNumber. What methods would accomplish this?
Answer:
A setter method
Explanation:
A setter method will accomplish this. A setter method is a method that takes in a value as an argument and grabs an object's instance variable and modifies it with the value passed as an argument. In this scenario, the argument value would be the current JerseyNumber. The setter method will grab the object's jerseyNumber variable and change its value to be the value of the passed argument. Setter methods are common practice in all object classes as well as the getter methods to retrieve instance variables.

Which of these is a good thing to consider when naming variables?
The name should be readable and make sense
Keep it short, less typing
Use only letters
O Sentences are Tood variable names.
Answer:
The name should be readable and make sense
Explanation:
Aside the rules involved in naming variables, there are also some good tips which should be considwred when given names to our variables. These means there are some variables which are acceptable by our program but may be avoided in other to make our codes easier to read by us and others and it also makes debugging easier when we run into errors. Using short variables are acceptable on code writing as far as the rules are followed. However, it is more advisable to use names that are descriptive and readable such that it relates to the program or code being worked on. This ensures that we and others can follow through our lines of code at a much later time without making mistakes or forgetting what the variable stands for.
A database designer wants to create three tables: Supplier, Product, and Country. The Supplier table has a Countryld column with values that must appear in the Country table's Countryld column. The Product table has an auto-increment column.
Which table's CREATE TABLE statement(s) must specify a FOREIGN KEY?
a. Supplier
b. Product
c. Country
d. Supplier and Country
Answer:
(a) Supplier
Explanation:
In database design, two tables are linked together using a FOREIGN KEY. A foreign key is formed from one or more columns of one table that reference or match another key (often called a primary key) in another table. In other words, when a column or a combination of columns on one table points to a primary key of another table, the column(s) will specify the foreign key.
PS: A primary key is used to make each entry of a table unique.
In the given tables - Supplier, Product, Country - since the Supplier table has a column called CountryId referencing the CountryId column of the Country table, then CountryId is a primary key in Country table but a foreign key in Supplier table.
Therefore, the CREATE TABLE statement(s) of the Supplier table must specify a foreign key.
A database management system often reads and writes data in a database, and makes sure there is consistency and availability. The supplier table's CREATE TABLE statement(s) must specify a FOREIGN KEY.
The database system often guards data when a lot of transactions is taking place. it often hinders multiple transactions with the same data at the same time.The Select SQL statement does not alter any database data. A supplier database is made up of different list of service, product or materials providers who can meet orders quickly.
