Answer:
None
Explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
Unfortunately, none of these answers would be factually nor grammatically correct. For Starters Kona is not an island Kailua-kona is the capital town of the Big Island in Hawaii.
Regardless of that fact, none of the answers given would make the sentence make sense grammatically. The Only way for the sentence to make sense grammatically, the answer either needs to stay blank or be Kailua. Like so...
Unlike the climate of the other islands of Hawaii, Kailua Kona contains 54 different temperate zones.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
The sentence should be completed with 'that of,' making it read 'Unlike the climate of the other islands of Hawaii, that of Kona contains 54 different temperate zones.' Hawaii's diverse climates are heavily influenced by altitudinal variations and topographical features, leading to a range of climatic zones across its islands.
The correct completion for the sentence provided is that of. Hence, the complete sentence reads: Unlike the climate of the other islands of Hawaii, that of Kona contains 54 different temperate zones.
Hawaii is known for its diverse climate conditions. While most islands in the Pacific have a tropical type A climate, Hawaii has a variety of climatic zones due to its topography and altitudinal variation. For instance, Kauai, one of the Hawaiian Islands, is one of the wettest places on Earth, receiving more than 460 inches of rain per year. This high level of precipitation is due to the rain shadow effect caused by Mt. Wai'ale'ale. The windward side of this mountain receives substantial rainfall while the leeward side remains semi-desert due to the rain shadow.
Japan, another island group, also presents diverse climates. One of its islands, Hokkaido, features a type D climate and is known for snowfall that supports activities like downhill skiing. Japan's diverse climate is a result of its mountainous terrain, with active volcanoes like Mount Fuji influencing the regional climate conditions.

Generally, a floating-point add instruction takes more clock cycles then a corresponding integer add instruction.
Answer:
True
Explanation:
A typical contemporary CPU knows two primary information classes: integer and floating point.
Floating point arithmetic instructions take more clock cycles than integer instructions.
Integer point generally takes 1 or 2 clock cycles for executing add instruction whereas floating point takes 3 or 4 instructions for executing add instruction.
Please explain external hashing, B-trees, and traversals. 3-5 sentences per
Answer: In external hashing the hash table is in disk where each slot of the page table holds multiple entries which refers to pages on the disk organised in the form of buckets.
B-trees are self balancing trees which contains sorted data and allows insertion, deletion, traversals
Traversal is the process of visiting the nodes of the tree data structure.
Explanation:
External hashing is different from internal hashing and it refers to concepts in database management systems. Internal hashing stores only single record maintained in page table format, whereas external hashing holds multiple entries.
B-trees are generalisation of binary trees where it can have more than 2 children.
Traversal of trees helps in insertion, deletion, modification of nodes in tree data structure

Applications where re-writeable optical laser disk would be preferred over hard disks for storage are:
While storing the data in large amount, the optical disk are more preferred as, for storing the videos, photographs and various types of the images.This optical laser disk are used for transferring the information or data from one computer to another so we can easily modify or re-write the data at any time as, this disk are more convenient than hard disk.The optical laser disk are also helpful for distributing the software to the customers or users by using its large storing capacity features, as compared to hard disks.
Answer:
The following are listed applications or requirements where the re-writable (optical) laser drive is preferred over storage hard drives.
Explanation:
A laser disk is often used to transmit data between one device to the next such that at any moment we could conveniently edit or re-write the details even though this drive is much more versatile than that of the disk.When processing the details in vast numbers, the optical disk is used to store certain photos, snapshots, and different file formats.As compared to hard disks, the optic disk has always been useful in delivering the applications to consumers or clients with its broad storage space functionality.Indicate which of the following substances contain an atom that does or does not follow the octet rule.
A. AlCl3
B. PCl3
C. PCl5
D. SiCl4
AlCl3 does not follow the octet rule because it has only six electrons in its valence shell after bonding. PCl5 also doesn't follow the octet rule as phosphorus extends beyond the octet by forming five covalent bonds using the d-orbitals.
To determine which substances contain an atom that does not follow the octet rule, we can evaluate the compounds listed: AlCl3, PCl3, PCl5, and SiCl4.
AlCl3 (Aluminum chloride): Aluminum has three valence electrons and forms three covalent bonds with chlorine atoms. However, it does not follow the octet rule because it only has six electrons in its valence shell after bonding.PCl3 (Phosphorus trichloride): Phosphorus has five valence electrons and forms three covalent bonds with chlorine atoms, leaving it with a full octet.PCl5 (Phosphorus pentachloride): Phosphorus can expand its valence shell beyond the octet rule, using the d-orbitals, to form five covalent bonds with chlorine atoms.SiCl4 (Silicon tetrachloride): Silicon has four valence electrons and forms four bonds with chlorine atoms, achieving a full octet.Based on this information, AlCl3 and PCl5 are examples where the central atom does not follow the octet rule. In the case of AlCl3, aluminum is electron-deficient with three bonds, whereas in PCl5, phosphorus exceeds the octet rule by forming five bonds.

Why Java Script uses the prefix Java in itsname?
Answer:
Java in JavaScript does not correspond to any relationship with Java programming language.
Explanation:
The prefix Java in Javascript is there for historical reasons.
The original internal name of Javascript when it was created by Brendan Eich at Netscape was Mocha. This was released to public as Livescript in 1995. The name Livescript was eventually changed to Javascript in Netscape Navigator 2.0 beta 3 release in December 1995 after Netscape entered into an agreement with Sun Microsystem. The primary purpose of change of name seemed to be as a marketing aid to benefit from the growing popularity of Java programming language at that time.

Answer:
Email is the electronic mail, basically it is in form of computer-based communication that consists of messages, which are sent and received using the Internet.
Email system works as:
The sender composed a message on their computer using the email client.When the user send the message, the email text and attachment are uploaded in Simple Mail Transfer Protocol(SMTP) server as the outgoing mail. All the messages wait in the outgoing email, while the SMTP server communicate with the Domain Name Server. If the SMTP server search the recipient’s email server, then it will transfer the attachments and the messages . When the next time recipient clicks on send and receive, then the client email download new message from their email server and then you got the mail.Imagine that 10 int values are labeled byposition: 1, 2, 3, etc. Write a program that reads 10integers and tracks how many of them have the same value as theirposition. That is, ifthe first number read is 1, or the third number is 3, that countsas a match, and the output would be the number of matches (from 0to 10). Use a singleif statement and a loop.
Answer:
#include<iostream>
using namespace std;
//main function
int main(){
//initialization
int count_Number=1,a1,match_Numbers=0;
//loop run 10 times
do{
cout<<"Enter the number: ";
//read the value enter by user
cin>>a1;
//check for match
if(a1==count_Number){
match_Numbers++;
}
count_Number++;
}while(count_Number <= 10);
//display the output
cout<<"The number of matches is: "<<match_Numbers<<endl;
return 0;
}
Explanation:
Include the library iostream for using the input/output instruction.
create the main function and declare the variables.
take the do-while loop which has a special property, the statement in the do-while execute first and then check the condition.
In the do-while, print the message by using the cout instruction and then store the value enter by the user into the variable.
then, check the value enter by the user is match the position or not. If the condition true, then count the matches and also update the position count.
this process continues until the position count is less than or equal 10. if condition false the loop terminates and then, display the output on the screen.

Explain the security mechanisms available for a database and how the data will be protected.
Answer: Views, unauthorized access, encryption are some of the security mechanisms.
Explanation:
The database of any application or software contains all the important data, therefore it is utmost necessary to protect the data from falling into dangerous hands. Most databases use authentication measures in form of passwords or bio metrics to avail access. Besides these users can use views to see the data but cannot change anything into the database. Some databases also use encryption systems to encrypt the passwords for better safety. There are some databases which grants user with two types of privileges such as system and object privileges, whereby with system privileges one can change the system environment variables.
A computer on a company network was infected with a zero-day exploit after an employee accidently opened an email that contained malicious content. The employee recognized the email as malicious and was attempting to delete it, but accidently opened it. Which of the following should be done to prevent this scenario from occurring again in the future? A. Install host-based firewalls on all computers that have an email client installed B. Set the email program default to open messages in plain text C. Install end-point protection on all computers that access web email D. Create new email spam filters to delete all messages from that sender
Answer:
A. Install host-based firewalls on all computers that have an email client installed
Explanation:
Since the employee accidentally opened the email that contained malicious content and the computer on the company network got infected, it needs to install host-based firewalls on all computers that have an email client installed on the system. A host-based firewall is a type of firewall installed on individual client or server which controls the incoming and outgoing networking data and identifies whether to allow it or not. The host-based firewall can easily identify and block suspected exploits like viruses, worms or trojan horses.
By installing host-based firewalls on all computers that have an email client installed secures the entire network of computers.
Answer:
The answer is C.
Explanation:
To prevent such thing from happening in the future, the employee/company should Install end-point protection on all computers that access web email
"What is the running time of HEAPSORT on an array A of length n thatis already sorted in increasing order?
Answer:
The answer to this question is O(NlogN).
Explanation:
The time complexity of Heap Sort on an array A is O(NLogN) even if the array is already sorted in increasing order.Since the Heap Sort is implemented by creating the heap from the array and then heapifying and then repeatedly swapping first and last element and deleting the last element.The process will be done for the whole array.So the running time complexity is O(NLogN).
For a set of integers stored in an array,calculate the sum of the positive numbers and the sum of the negative numbers. The program should store these numbers in memory variables: positiveSum and negativeSum. Numbers should be read from the array one at a time with a zero value (0) being used to signal the end of data (the zero value is acting as a "sentinel" value).
Answer: The c++ program to implement the given conditions is shown below.
#include <iostream>
using namespace std;
int main()
{
// used as index of array in the loop for calculating the sum
int i=0;
// array contains both negative and positive integers
// 0 is used as the sentinel value
int arr[12]={-9,-8,-3,-12,-78,-10,23,45,67,1,0};
int positiveSum=0, negativeSum=0;
do
{
if(arr[i]<0)
negativeSum = negativeSum + arr[i];
if(arr[i]>0)
positiveSum = positiveSum + arr[i];
// after every element is added, index of array represented by i is incremented
i++;
}while(arr[i]!=0);
// loop continues till end of array is reached
cout<<"Sum of positive integers "<<positiveSum<<" and sum of negative integers "<<negativeSum<<endl;
return 0;
}
OUTPUT
Sum of positive integers 136 and sum of negative integers -120
Explanation: This program declares and initializes an integer array without user input. As mentioned in the question, 0 is taken as the sentinel value which shows the end of data in the array.
int arr[12]={-9,-8,-3,-12,-78,-10,23,45,67,1,0};
All the variables are declared with data type int, not float. Since, integers can yield integer result only.
The do-while loop is used to calculate the sum of both positive and negative integers using int variable i. The variable i is initialized to 0.
This loop will run till it encounters the sentinel value 0 as shown.
while(arr[i]!=0);
Hence, all the integers in the array are read one at a time and sum is calculated irrespective of the element is positive or negative.
if(arr[i]<0)
negativeSum = negativeSum + arr[i];
if(arr[i]>0)
positiveSum = positiveSum + arr[i];
After the element is added, variable i is incremented and loop is continued.
The do-while loop tests positive and negative integers based on the fact whether their value is greater than or less than 0.
The program can be tested using different size and different values of positive and negative integers in the array.
IRQ 0 interrupt have _______________ priority
? low
? medium
? highest
? lowest
Answer:
Highest
Explanation:
A interrupt request / IRQ is in which instructions are sent to Cpu and uses an interrupt handler to run distinct program . Hardware interrupts are used to manage occurrences such as obtaining modem or network card information, important presses, or mouse motions.
Interrupt request 0. – it is a system timer (can not be altered) Interrupt request 1 – keyboard controller (can not be changed) Interrupt request 2 – cascaded IRQ 8–15 signals (any device configured to use IRQ 2 will genuinely use IRQ 9) Interrupt request 3 – serial port 2 controller Interrupt request 4 – serial port 1 controller Interrupt request 5 –parallel port 2 and 3 Interrupt request 6 - floppy disk controller Interrupt request 7 –parallel port 1. If a printer is not present, it is used for printers or for any parallel port. It can also possibly be shared with a secondary sound card with cautious port management.As interrupt number increases priority level decreases, Priority level 0 is the highest priority level .
Which of the following is not anadvantage of simulation?
Ability to treatcomplex situations
Ability to deriveoptimal solutions
Ability to askwhat-if questions
Ability toexperiment with different scenarios
Ability tocompress time
Answer: Ability to derive optimal solutions
Explanation:
One of the main disadvantages of simulation is ability to derive optimal solutions. As, the solution does not required to have a closed form and procedure does not require any weighting and the hard constraint. Stimulation outcome are not optimal to induced specific response because of the lack of quantitative models.
The expressionvecCont.empty() empties the vector container of allelements.
a. True
b. False
Answer:
False
Explanation:
vector is like a dynamic array that has a special ability to resize automatically when it required.
vector has several functions:
like, insert() to insert the element in the vector.
delete() for delete the one element at a time.
empty() is also the function used in the vector. It is used for checking the vector is empty or not.
it gives the Boolean value (TRUE or FALSE), if the vector is empty it gives the output TRUE if the vector is not empty it gives the output FALSE.
It is not used for empty or deletes all elements of the vector.
Therefore, the answer is False.
The n modifier after the tilde forces the index variable to expand only to the ______
Answer: filename and extension.
Explanation:
Suppose we have %~nxa, where we have two modifiers n and x, and a single variable a.
So, the n modifier after the tilde forces the index variable to expand only to the filename(by the n modifier) and the extension(by the x modifier).
It produces the filename and extension instead of the full path.
What is the value of x after the following statements execute? int x, y, z; y 12; z 3; X= (y*(z+y-10); A. 36 B. 144 C.60 D. None of these
Answer:
60
Explanation:
According to the operator precedence, the bracket comes in the top. So, the program solve expression in the bracket first.
In the code, the value of Y is 12 and z is 3
substitute the value in the formula.
X = (12*(3 + 12 - 10)).
So, the program calculate the value (3 + 12 - 10) first which gives 5.
After that program evaluate (12 * 5) which gives 60.
Therefore, the answer is 60.
