Explanation:
You work part time at a computer repair store. You just upgraded the processor in a customer's computer. The computer starts, but it shuts down shortly after starting Windows. Because you know that the problem is related to the processor, you will check any issues related to the processor installation. In this lab, you task is to diagnose and correct the problem.
Answer:
Explanation:
If the computer is starting up and getting into windows then this means that the processor itself is not dead. First, check to see if the processor fan is spinning correctly when turning on the computer. If it is, then you will need to remove it, and make sure that the processor is perfectly slotted within the cpu slot and that no pins are bent. If this is the case, then clean the cpu top with an alcohol swab and reapply thermal paste. If it is overheating due to any of these reasons it would cause the pc to power off in order to preserve the processor. If none of these fix the problem then it might be a faulty processor or a problem with another component such as the RAM or power cables.

Why is it easier to spot a syntax error than a logical error?
Answer:
Even small typos that do not produce syntax errors may cause logic errors. ... The logic error might only be noticed during runtime. Because logic errors are often hidden in the source code, they are typically harder to find and debug than syntax errors.Explanation:
Using a loop and indexed addressing, write code that rotates the members of a 32-bit integer array forward one position. The value at the end of the array must wrap around to the ?rst position. For example, the array [10,20,30,40] would be transformed into [40,10,20,30].
//begin class definition
public class Rotator{
//main method to execute the program
public static void main(String []args){
//create and initialize an array with hypothetical values
int [] arr = {10, 20, 30, 40};
//create a new array that will hold the rotated values
//it should have the same length as the original array
int [] new_arr = new int[arr.length];
//loop through the original array up until the
//penultimate value which is given by 'arr.length - 1'
for(int i = 0; i < arr.length - 1; i++ ){
//at each cycle, put the element of the
//original array into the new array
//one index higher than its index in the
//original array.
new_arr[i + 1] = arr[i];
}
//Now put the last element of the original array
//into the zeroth index of the new array
new_arr[0] = arr[arr.length - 1];
//print out the new array in a nice format
System.out.print("[ ");
for(int j = 0; j < new_arr.length; j++){
System.out.print(new_arr[j] + " ");
}
System.out.print("]");
}
}

Write a function NumberOfPennies() that returns the total number of pennies given a number of dollars and (optionally) a number of pennies. Ex: 5 dollars and 6 pennies returns 506.
Sample program:
#include
using namespace std;
int main() {
cout << NumberOfPennies(5, 6) << endl; // Should print 506
cout << NumberOfPennies(4) << endl; // Should print 400
return 0;
Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
int NumberOfPennies(int ND, int NP=0)//defining a method that accepts two parameters
{
return (ND*100 +NP);//use return keyword that fist multiply by 100 then add the value
}
int main() //main method
{
cout << NumberOfPennies(5,6) << endl; // Should print 506
cout << NumberOfPennies(4) << endl; // Should print 400
return 0;
}
Output:
506
400
Explanation:
In the method "NumberOfPennies" it accepts two parameters that are "ND and NP" that uses the return keyword that multiply 100 in ND variable and add in NP variable and return its values.
In the main method it it uses the cout method that call the by accepts value in parameter and print its value.
Character positions in
arrays start counting with
the number 1.
True
False
Answer:
False.
Explanation:
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
In Computer programming, an array can be defined as data structure which comprises of a fixed-size collection of variables each typically holding a piece of data and belonging to the same data type such as strings or integers.
This ultimately implies that, when a programmer wishes to store a group of related data (elements) of the same type, he or she should use an array.
Generally, character positions in arrays start counting with the number 0 not 1.
Hence, an array uses a zero-based indexing and as such the numbering or position of the characters (elements) starts from number 0. Thus, the first character (element) in an array occupies position zero (0), the second number one (1), the third number two (2) and so on.
The following implementations of the method reverse are intended to reverse the o rder of the elements in a LinkedList.

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:
c. Ill only
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.
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 ());

The following Integer values are pushed onto a stack, s. The values are pushed onto s in the order that they appear below (left to right).
1 7 4 6 10 9
Assume the following declaration has been made.
PriorityQueue priQue new PriorityQueuecinteger> :
Values are popped off the stack, s, and as each value is popped off the stack, it is inserted into the priority queue, priQue. The following code is then executed.
while (!priQueue.isEmpty()){
System.out.println (priQue.remove ())
The numbers printed to the screen would be: ______
Answer:
9 10 6 4 7 1
Explanation:
When the values are pushed to the stack they would end up in the stack in the same order as they go in.
1 7 4 6 10 9
when elements are popped from a stack they are removed from the end to the beggining of the stack, and since these elements are being added to the priorityQueue then priQue will have the following order
9 10 6 4 7 1
this will also be the order that the numbers will be printed out from left to right since priorityQueue remove method, removes the elements from left to right.

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

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.
Identify the logic error in the code below. The code is supposed to display a single message “child”, “adult” or “senior” for any value of age:
if (age < 18) {
System.out.println("child");
} else if (age >= 18) {
System.out.println("adult");
} else if (age > 65) {
System.out.println("senior");
}
Question 1 options:
a)
no message for age = 65
b)
too many messages for age = 18
c)
no message for age < 65
d)
message “senior” will never be displayed
If we take a look at the first else if block, the code runs whenever the age is greater than or equal to 18. This means that senior will never be displayed. Answer choice D is correct.
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
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.

The moment that S-locks are released will determine:__________
a. The granularity of locks
b. The compliance with ACID
c. The look-ahead logging strategy
d. The anomalies that can happen
Answer:
A.
Explanation:
In computer science, the selection of a lockable device is an essential consideration in the creation of a database management system.
Granularity locking is a locking technique that is applied in database management systems (DBMS) as well as relational databases. The granularity of locks corresponds to how much data is locked at once, and it is determined when S lock (Shared Locks) are released.
The moment that S-locks are released will determine the granularity of locks (Option a).
A lock can be defined as a procedure capable of enforcing limits on access to a particular resource when there exist many threads of execution.Multiple granularity locking (abbreviated as MGL) is a locking strategy employed in database management systems and also in relational databases. This strategy (multiple granularity locking) is often used in order to ensure serializability.In conclusion, the moment that S-locks are released will determine the granularity of locks (Option a).
