Internal Fragmentation occurs when a process needs more space than the size of allotted memory block or use less space. External Fragmentation occurs when a process is removed from the main memory. Internal Fragmentation occurs when Paging is employed. External Fragmentation occurs when Segmentation is employed.
A bigger chunk of RAM is set aside for the process. Some memory is left unused because it cannot be utilised by another function. By properly allocating the smallest division that is yet large enough for the process, internal fragmentation can be reduced.
When there is a mismatch between the quantity of memory needed and the amount of memory that is actually available, internal fragmentation becomes a problem.
When paging is used, internal fragmentation occurs.
When memory allocations are made but chunk sizes are fixed, internal fragmentation follows.
Internal process fragmentation occurs when a process consumes less memory or uses more than the allocated memory block can hold.
External FragmentationAlthough the total RAM is large enough to accommodate a process or handle a request, we are unable to use it since it is not contiguous. To lessen external fragmentation, we can condense or shuffle memory to free up a substantial amount of space. For compaction to be useful, relocation must be dynamic.
Internal fragmentation is largely controlled via Best Fit Block Search.
External fragmentation is fixed through compaction.
When the size of the allotted memory blocks fluctuates, external fragmentation occurs.
When segmentation is used, external fragmentation happens.
When small, non-contiguous memory blocks cannot be assigned to any process, external fragmentation results.
An affected process is deleted from the main memory as a result of external fragmentation.
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.

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.
how do you design and create video games for what console game That you want To have it in
Answer
Making a video game is much less daunting than it might seem. While you likely aren’t going to go from having no experience to making the next Grand Theft Auto, it has actually never been easier to get started making games. Game development tools and resources have become increasingly accessible to the average person, even if they have no programming experience. Often these tools are also available for free.
To try to make things easier for those looking to get started making games, we’ve put together a list of 11 game engines / editors. Some are designed for a specific genre of game or to be incredibly easy for newcomers. Others are professional development tools for AAA games, but are effectively free to use for hobbyists and still offer a lot of learning tools to help those with limited programming experience get started.
There are, of course, a lot of things that go into game development — music, animation, sound, writing, texturing, modeling, etc. — however, the game engine / editor you choose is going to have the biggest effect on what kind of game you can make. If you have suggestions for other engines, software, or learning tools for the other aspects of development, post it in the comments.

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 ∑:

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.

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.

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.
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.

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
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.

Which of these actions will help build relationships with customers : A. Empowering employees to provide the best service possible B. Make follow- up calls after service transactions C. Ask for customer opinions on possible improvements D. all of the above
Answer: D. all of the above
Explanation:
Customers want to be provided with good service when they shop so it is important that employees are able to do so and they can only do so if they have the tools required. The company should therefore make those tools available thereby empowering employees to provide great service.
Making follow-up calls to customers after they receive a service to check if the service is working out will build customer relations because they will feel that the company cares. Finally, asking customers of their opinions on improvements needed makes them feel they have a voice and will go a long way in establishing rapport with them.
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).
