Final answer:
When a computer is only capable of manipulating integers, difficulties arise with decimal numbers. However, these difficulties can be overcome by using different data types and algorithms. Programming languages and libraries provide tools to handle decimal numbers accurately.
Explanation:
When a computer is only capable of manipulating and storing integers, difficulties arise when working with numbers that involve decimal points or fractions. This is because computers work with binary numbers, which only consist of the digits 0 and 1. Decimal numbers cannot be represented directly in binary notation.
However, these difficulties can be overcome by using different data types and algorithms. For example, floating-point numbers can be used to represent decimal numbers in a binary format. Algorithms can be developed to perform mathematical operations on these floating-point numbers, allowing computers to work with a wider range of numeric values.
Programming languages and libraries provide built-in functions and methods to handle decimal numbers and perform arithmetic operations accurately. By using these tools, computer programmers can effectively work with integers, as well as decimal numbers, without losing accuracy.

If you need a function to get both the number of items and the cost per item from a user, which would be a good function declaration to use?
Answer:
double costAndNumItems (int numOfItems, double costPerItem){
return 0;
}
Explanation:
Above is how functions/methods are declared in Java programming language. We speficify the functions return type (double in this case), this is followed by the function's name costAndNumItems and then the arguments list which specifies the list of parameters that this function will accept. (numOfItems and costPerItem) followed by an open and close braces. Inside the braces is where the code for the functions behaviour is defined.

Why is it important that your case and motherboard share a compatible form factor?
When might you want to use a slimline form factor?
What advantages does ATX have over Micro-ATX?
What are two operating systems that can be installed in systems using Mini-ITX motherboard?
Is it possible to identify the form factor without opening the case?
Answer:
It is important for your case to share a compatible form factor because different cases have different compatibilities. For example if you have a Micro-ATX case, a full ATX motherboard would be too large to fit into that case.
You might want to use a slimline form factor if you have limited space.
With a full ATX you will be able to add more as well as larger components, where as if you get a Micro-ATX, you would be limited.
The two OS are Linux and Windows.
Normally you can eye ball it by determining the size and shape of the case.

If you think a query is misspelled, which of the following should you do? Select all that apply.
A) Assign a low utility rating to all results because misspelled queries don't deserve high utility ratings.
B) Release the task.
C) For obviously misspelled queries, base the utility rating on user intent.
D) For obviously misspelled queries, assign a Low or Lowest Page Quality (PQ) rating.
Answer:
The answer is: letter C, For obviously misspelled queries, base the utility rating on user intent.
Explanation:
The question above is related to the job of a "Search Quality Rater." There are several guidelines which the rater needs to consider in evaluating users' queries. One of these is the "User's Intent." This refers to the goal of the user. A user will type something in the search engine because he is trying to look for something.
In the event that the user "obviously" misspelled queries, the rate should be based on his intent. It should never be based on why the query was misspelled or how it was spelled. So, no matter what the query looks like, you should assume that the user is, indeed, searching for something.
Rating the query will depend upon how relevant or useful it is and whether it is off topic.
Answer:
C) For obviously misspelled queries, base the utility rating on user intent.
Explanation:
Query is the term used to describe a language that the computer uses to perform query activities in different databases. It is important that the query is done correctly, or the data found by it may not be ideal for what the user is looking for. However, if the user suspects that a query is showing inefficient results, or that the query is incorrect, the ideal thing to do is to make sure that the query is incorrect and obtain results based on the utility rating on user intent.

Write a Python function called simulate_observations. It should take no arguments, and it should return an array of 7 numbers. Each of the numbers should be the modified roll from one simulation. Then, call your function once to compute an array of 7 simulated modified rolls. Name that array observations.
Final answer:
The 'simulate_observations' Python function simulates rolling a six-sided die 7 times, storing the results in an array named 'observations'.
Explanation:
To write a Python function called simulate_observations which returns an array of 7 simulated modified rolls, we can use the random module's randint function to simulate the rolling of a six-sided die. The code snippet below defines the function that generates 7 random numbers, each representing the outcome of a die roll, and stores them in an array called observations.
import random
def simulate_observations():
results = []
for _ in range(7):
roll = random.randint(1, 6)
results.append(roll)
return results
observations = simulate_observations()
print(observations)
Each number in the array would be between 1 and 6, representing each side of a fair, six-sided die. Note that the modification mentioned in the question is not specified, thus the standard roll result is used.
The Python function simulate_observations generates an array of 7 modified dice rolls and returns it. The example provided shows step-by-step how to implement and modify the rolls. The resulting array is stored in 'observations'.
To create a Python function called simulate_observations that returns an array of 7 modified dice rolls, you can follow these steps:
Define the function simulate_observations that uses the random module to generate random numbers simulating dice rolls.
Modify each simulated dice roll as specified (for example, by adding a constant to each roll).
Return the array of modified rolls.
Here's an implementation of the function:
import randomThis code will generate 7 random dice rolls, modify each by adding 1, and store them in the observations array. The mean expectation for dice rolls, centered around 3.5 for a fair six-sided die, is slightly adjusted due to modification.
Using a script (code) file, write the following functions:
1. Write the definition of a function that take one number, that represents a temperature in Fahrenheit and prints the equivalent temperature in degrees Celsius.
2. Write the definition of another function that takes one number, that represents speed in miles/hour and prints the equivalent speed in meters/second.
3. Write the definition of a function named main. It takes no input, hence empty parenthesis, and does the following:
O prints Enter 1 to convert Fahrenheit temperature to Celsius
O prints on the next line, Enter 2 to convert speed from miles per hour to meters per second.
O take the input, lets call this main input, and if it is 1, get one input then call the function of step 1 and pass it the input.
O if main input is 2, get one more input and call the function of step 2.
O if main input is neither 1 or 2, print an error message.
After you complete the definition of the function main, write a statement to call main.

Suppose a host has a 1-MB file that is to be sent to another host. The file takes 1 second of CPU time to compress 50%, or 2 seconds to compress 60%.
(a) Calculate the bandwidth at which each compression option takes the same total compression + transmission time.
(b) Explain why latency does not affect your answer.
Answer: bandwidth = 0.10 MB/s
Explanation:
Given
Total Time = Compression Time + Transmission Time
Transmission Time = RTT + (1 / Bandwidth) xTransferSize
Transmission Time = RTT + (0.50 MB / Bandwidth)
Transfer Size = 0.50 MB
Total Time = Compression Time + RTT + (0.50 MB /Bandwidth)
Total Time = 1 s + RTT + (0.50 MB / Bandwidth)
Compression Time = 1 sec
Situation B:
Total Time = Compression Time + Transmission Time
Transmission Time = RTT + (1 / Bandwidth) xTransferSize
Transmission Time = RTT + (0.40 MB / Bandwidth)
Transfer Size = 0.40 MB
Total Time = Compression Time + RTT + (0.40 MB /Bandwidth)
Total Time = 2 s + RTT + (0.40 MB / Bandwidth)
Compression Time = 2 sec
Setting the total times equal:
1 s + RTT + (0.50 MB / Bandwidth) = 2 s + RTT + (0.40 MB /Bandwidth)
As the equation is simplified, the RTT term drops out(which will be discussed later):
1 s + (0.50 MB / Bandwidth) = 2 s + (0.40 MB /Bandwidth)
Like terms are collected:
(0.50 MB / Bandwidth) - (0.40 MB / Bandwidth) = 2 s - 1s
0.10 MB / Bandwidth = 1 s
Algebra is applied:
0.10 MB / 1 s = Bandwidth
Simplify:
0.10 MB/s = Bandwidth
The bandwidth, at which the two total times are equivalent, is 0.10 MB/s, or 800 kbps.
(2) . Assume the RTT for the network connection is 200 ms.
For situtation 1:
Total Time = Compression Time + RTT + (1/Bandwidth) xTransferSize
Total Time = 1 sec + 0.200 sec + (1 / 0.10 MB/s) x 0.50 MB
Total Time = 1.2 sec + 5 sec
Total Time = 6.2 sec
For situation 2:
Total Time = Compression Time + RTT + (1/Bandwidth) xTransferSize
Total Time = 2 sec + 0.200 sec + (1 / 0.10 MB/s) x 0.40 MB
Total Time = 2.2 sec + 4 sec
Total Time = 6.2 sec
Thus, latency is not a factor.
Final answer:
The bandwidth at which each compression option (50% and 60%) takes the same total compression plus transmission time is 10 MBps. Latency does not impact this calculation because it is a separate factor from compression and transmission rates.
Explanation:
To calculate the bandwidth at which each compression option takes the same total compression + transmission time:
For 50% compression: The file size becomes 0.5 MB (50% of 1 MB) which requires 1 second of compression time. This gives a total of 0.5 MB to be transmitted.For 60% compression: The file size becomes 0.4 MB (40% of 1 MB) which requires 2 seconds of compression time. This gives a total of 0.4 MB to be transmitted.Let t be the transmission time and B be the bandwidth in MBps. The total time for both scenarios needs to be equal, so:
For 50% compression: 1 second (compression time) + (0.5 MB / B) = tFor 60% compression: 2 seconds (compression time) + (0.4 MB / B) = tSetting the equations equal to each other gives us:
1 + (0.5 / B) = 2 + (0.4 / B)
After solving, B = 10 MBps.
(b) Latency does not affect the answer because it refers to the delay before the transfer begins and does not impact the rate of data transmission or compression time.
Your program Assignment This game is meant for tow or more players. In the same, each player starts out with 50 points, as each player takes a turn rolling the dice; the amount generated by the dice is subtracted from the player's points. The first player with exactly one point remaining wins. If a player's remaining points minus the amount generated by the dice results in a value less than one, then the amount should be added to the player's points. (As a alternative, the game can be played with a set number of turns. In this case the player with the amount of pints closest to one, when all rounds have been played, sins.)

Assume a system uses five protocol layers. If the application program creates a message of 100 bytes and each layer (including the fifth and the first) adds a header of 10 bytes to the data unit, what is the efficiency (the ratio of application layer bytes to the number of bytes transmitted) of the system?
Answer:
66.7 %
Explanation:
If the message created by the application layer, is 100 bytes size, and any of the five protocol layers add 10 bytes to the data unit, when transmitted, the packet will have 150 bytes, from which, 50 bytes are overhead bytes.
So, the efficiency (ratio of application layer bytes (excluding the header) to the number of bytes transmitted) of the system is as follows:
E = 100 / 150 = 66.7 %
The efficiency is the ratio of the application later bytes to the total bytes transmitted. Hence, the efficiency is 66.67%.
Application layer bytes = 100 bytes
The number of bytes transmitted can be calculated thus :
(Number of protocol layers × header size) + message size (5 × 10) + 100 = 150 bytesThe efficiency can be calculated thus :
Application layer bytes / number of bytes transmittedEfficiency = (100 ÷ 150) × 100%
Efficiency = 0.666 × 100% = 66.67%
Therefore, the efficiency is 66.67%

In the following data definition, assume that List2 begins at offset 2000h. What is the offset of the third value (5)?
List2 WORD 3,4,5,6,7
a. 20008h
b. 2002h
c. 2000h
d. 2004h
Answer:
The offset of the third value (5) is 2004h
Explanation:
Offset is the distance from a starting point, either the start of a file or the start of a memory address.
The value is added to a base value to derive the actual offset value.
In the question above,
The base value = 3 because the item is at the 3rd position
Hence, the offset position = 3 + 1 = 4
Note that the offset begins at 2000
So, the offset value of 5 = 2000 + 4
Offset = 2004h
The offset of the third value (5) in the array List2, which begins at offset 2000h, is 2004h because each WORD value occupies 2 bytes, and the index of the third value is 2.
Explanation:The data definition given is for an array of WORD values starting at offset 2000h. In assembly language or low-level programming, a WORD typically represents a 16-bit (2-byte) value. Since the array starts at offset 2000h and each value in the array occupies 2 bytes, we can calculate the offset for each value by adding 2 times the index of the desired value (since indexing starts at 0) to the starting offset.
The third value in the array (which is the value 5) has an index of 2 (as we start counting from 0). Thus, the offset for the third value is computed as:
Starting offset + (Index of value * Size of each value)
2000h + (2 * 2) = 2000h + 4 = 2004h
Hence, the correct offset for the third value in the array is 2004h.
____ is the risk control approach that attempts to reduce the impact caused by the exploitation of vulnerability through planning and preparation.
Answer: mitigation
Explanation:
Answer:
The correct word for the blank space is: Mitigation.
Explanation:
Mitigation is the set of actions taken to reduce the impact of vulnerability after a threat has exploited it. How effective mitigation will depend on the speed of detection and response to the threat. Part of mitigation also comprehends setting up plans of contingency in front of the attacks to protect the information of the company that could be compromised.
In order to recover from an attack on any one server, it would take an estimated 14 hours to rebuild servers 1, 2, 3, and 4 and 37 hours to rebuild server 5. If each server is required to be online 8,760 hours a year, compute the EF for each server.
Answer:
It is an approximate time to rebuild servers to satisfy either ourselves or management.
Explanation:
To rebuild the server all depends on CPU and process time taken by each individual server time taken.
Some servers to rebuild will take less time because the effected server is very less moreover some patches have to download from the internet and if downloading speed is very less then it will be a delay on the rebuild or recovering process. Suppose internet downloading speed fast enough but internal data operation speed is very low profile than their will in the delay to rebuild the servers.
Best practice method to restore from the last backup so the delay time to rebuild the server is known.
How are signals clocked and how does that affect data transmission? What does it mean when a signal is self-clocking? How does baud rate differ from bits per second? Explain the relationship between frequency and Baud Rate.
Answers:
- Clock signal with clock generator or self-clock.
- self clocking is automatically synchronized.
- Baud-rate is the signal change per second, while BPS is number of bits sent per second.
- Frequency = Baud-rate/ 1000 .
Explanation:
Signals are clocked using neither a clock generator on the signal to synchronize it to the click generator time frame or self-clocking the signal. A self-clocking signal is a signal that does not need a clocking signal or clock generator to decode it. Baud rate is the number if signal change per time, while but per second is the number of bits sent at a second. Frequency is the baud rate divided by 1000.
Final answer:
Signals are clocked using a reference timing signal that coordinates data transmission. A self-clocking signal embeds timing information, allowing synchronization without a separate clock. Baud rate, differing from bits per second, measures the number of signal units sent per second, which could represent multiple bits, depending on the encoding scheme.
Explanation:
Signals are clocked by using a reference timing signal, allowing the synchronization of data transmission across systems. In digital electronics, a clock signal is a particular type of signal that oscillates between a high and a low state and is used primarily to coordinate the actions of circuits.
A self-clocking signal includes timing information within the signal itself, which allows the receiver to synchronize with the transmitter without the need for a separate clock signal.
The baud rate is a measure of the number of signal units per second. Each signal unit may represent more than one bit of information, which is why baud rate and bits per second can be different. For instance, in the case of a signal which uses four different phase angles, each angle (signal unit) can represent two bits, so the baud rate would be half the bitrate.
The frequency of a signal is the rate at which the waveform repeats itself, whereas baud rate refers to the number of symbols per second. In digital communications, the carrier wave frequency is typically much higher than the baud rate.

Drivers are necessary before installing any hardware device such as if the user installs motherboard than they have to install the correct driver for the following motherboard.
Consider the method total below:
public static int total (int result, int a, int b){ if (a == 0) { if (b == 0) { return result * 2; } return result / 2; } else { return result * 3; }}
The assignment statementx = total (1, 1, 1);must result in:A. x being assigned the value 3 B. x being assigned the value 7C. x being assigned the value 5D. x being assigned the value 2E. x being assigned the value 0
Answer:
Explanation:
When you look at the assignment "x = total (1, 1, 1);", you can see that result, a and b all refers to 1. Then, you need to go to the function and check the conditions. The first condition is "if (a == 0)", it is not true because a is assigned to 1. Since that is not true, you need to go to the else part "else { return result * 3". That means the result of this function is going to give us 3 (because result variable equals to 1 initially). That is why x is going to be assigned as 3.
In which type of modulation is a 1 distinguished from a 0 by shifting the direction in whichthe wave begins?
a.bandwidth modulation
b.amplitude modulation
c.frequency modulation
d.phase modulation
e.codec modulation
Answer:
E. Codec modulation
Explanation:
Codec is used to encode digital signals for transmission.
Amplitude modulation uses the amplitude of the carrier wave to encode or modulate the information for transmission.
The phase of a wave changes with respect to the amplitude, so information is modulated with the phase angle as amplitude changes in phase modulation.
Bandwidth modulation is a form of modulation that encode the information of a fixed bit size based on the frequency of the carrier wave. It is similar to frequency modulation, but frequency modulation modulate a signal wave information.
Phase modulation is a type of modulation where one (1) is distinguished from zero (0) by shifting the direction in which the wave begins (Option d).
Analog transmission refers to a methodology of transmission that transmits information by a continuous signal, which can vary in amplitude, phase, and other characteristics related to the proportion of such information.Phase modulation is a pattern used for conditioning communication signals and then for the transmission of that signals.This type of modulation (phase modulation) employs variations in phase and amplitude for carrying out the modulation and it is used for analog transmission.In conclusion, phase modulation is a type of modulation where one (1) is distinguished from zero (0) by shifting the direction in which the wave begins (Option d).

In this warm up project, you are asked to write a C++ program proj1.cpp that lets the user or the computer play a guessing game. The computer randomly picks a number in between 1 and 100, and then for each guess the user or computer makes, the computer informs the user whether the guess was too high or too low. The program should start a new guessing game when the correct number is selected to end this run (see the sample run below).
Check this example and see how to use functions srand(), time() and rand() to generate the random number by computer.
Example of generating and using random numbers:
#include
#include // srand and rand functions
#include // time function
using namespace std;
int main()
{
const int C = 10;
int x;
srand(unsigned(time(NULL))); // set different seeds to make sure each run of this program will generate different random numbers
x = ( rand() % C);
cout << x << endl;
x = ( rand() % C ); // generate a random integer between 0 and C-1
cout << x << endl;
return 0;
}
Answer:
#include <iostream>
#include <time.h>
using namespace std;
int main()
{
// Sets the random() seed to a relatively random number
srand(time(0));
// Variables are defined
int RandomNumber = rand() % 100 + 1, UserSelection, Tries = 5;
// Gets a number from the user
cout << " Guess a number between 1 and 100, you have five tries to find the correct number.\n :";
cin >> UserSelection;
// Prevents the user from selecting a number out of bounds
while (UserSelection > 100 || UserSelection < 1)
{
cout << " I said between 1 and 100. select a new number BETWEEN 1 AND 100!\n :";
cin >> UserSelection;
}
// Stuck in while till they guess right, or run out of tries
while (UserSelection != RandomNumber)
{
// kicks user from the loop when they run out of tries
Tries -= 1;
if (Tries == 0)
{
break;
}
// Tells the user they got the wrong number and how many tries they have left
cout << " The Number was not correct, you have " << Tries << " more Guess(es) left.";
// Tells the user if they are above the number
if (UserSelection > RandomNumber)
{
cout << " Try guessing a little lower\n :";
}
// Tells the user if they are bellow the number
else if (UserSelection < RandomNumber)
{
cout << " Try guessing a little higher\n :";
}
// User input if the number is wrong they stay in the loop, if they are right they fail the condition for the loop and get dialogue according to how many tries they have left
cin >> UserSelection;
// Prevents the user from selecting a number out of bounds
// If the number is greater than 100 or less than 1 they are prompted to select a new number
while (UserSelection > 100 || UserSelection < 1)
{
cout << " I said between 1 and 100. select a new number BETWEEN 1 AND 100!\n :";
cin >> UserSelection;
}
}
// The amount of tries the user has left determines what dialogue they get
// First try win
if (Tries == 5)
{
cout << " That's not luck, that's skill. you got the number right on the first try.\n ";
system("pause");
}
// Second try win
else if (Tries == 4)
{
cout << " That's pretty good luck, you guessed it right on the second try.\n ";
system("pause");
}
// Third try win
else if (Tries == 3)
{
cout << " Could be better, but it could also be way worse. You got it right on the third try.\n ";
system("pause");
}
// Fourth try win
else if (Tries == 2)
{
cout << " Could be worse, but it could also be a lot better. You got it right on your fourth try.\n ";
system("pause");
}
// Fifth try win
else if (Tries == 1)
{
cout << " I hope you don't gamble much. You got it right on your last guess.\n ";
system("pause");
}
// Losing dialogue
else
{
cout << " You guessed wrong all five times, the right number was " << RandomNumber << "\n ";

Read the comments in the code they roughly explain whats going on.
Write a program that prompts the user to input the number of quarters, dimes, and nickels. The program then outputs the total value of the coins in pennies.
Final answer:
The question asks for a program to calculate the total value in pennies of a given number of quarters, dimes, and nickels, with a solution presented in Python.
Explanation:
Each quarter is worth 25 pennies, each dime is worth 10 pennies, and each nickel is worth 5 pennies. To calculate the total value, you multiply the number of each type of coin by its value in pennies and sum up these values.
For example, if a user inputs 3 quarters, 2 dimes, and 1 nickel, the program will calculate the total value as (3 * 25) + (2 * 10) + (1 * 5) = 95 pennies.Sample Python code:
quarters = int(input('Enter the number of quarters: '))Write a function called first_last that takes a single parameter, seq, a sequence. first_last should return a tuple of length 2,where the first item in the tuple is the first item in seq, and the second item in tuple is the last item in seq. If seq is empty, the function should return an empty tuple. If seq has only one element, the function should return a tuple containing just that element.
Answer:
The Python code with the function is given below. Testing and output gives the results of certain chosen parameters for the program
Explanation:
def first_last(seq):
if(len(seq) == 0):
return ()
elif(len(seq) == 1):
return (seq[0],)
else:
return (seq[0], seq[len(seq)-1])
#Testing
print(first_last([]))
print(first_last([1]))
print(first_last([1,2,3,4,5]))
# Output
( )
( 1 , )
( 1 , 5 )

Suppose that Smartphone A has 256 MB RAM and 32 GB ROM, and the resolution of its camera is 8 MP; Smartphone B has 288 MB RAM and 64 GB ROM, and the resolution of its camera is 4 MP; and Smartphone C has 128 MB RAM and 32 GB ROM, and the resolution of its camera is 5 MP. Determine the truth value of each of these propositions.
Answer:
Explanation:
1 True Smartphone B has 288 MB RAM, which is the most out of the other two phones.
2 True Either the ROM has to be greater or the resolution has to be greater. The resolution is greater in this example so it is true.
3 False It is false because the resolution is larger in Smartphone A.
4. False It may have more RAM and ROM, but Smartphone B's resolution is less making the statement false
5. False It is a biconditional statement which is F - T making the statement false.
