Answer:
Explanation:
Usually, applications would have the capability of using either one of these options. But for the sake of the question here are some that usually prefer one method over the other.
Any program that targets an API usually uses Sequential access. This is because API's contain all of the data as objects. Therefore, you need to access that object and sequentially navigate that object to the desired information in order to access the data required.
A music application would have access to an entire folder of music. If the user chooses to set the application to randomly play music from that folder, then the application will use a Random Access method to randomly choose the music file to load every time that a song finishes.

If a TCP receiver advertises a window size of 5,718 bytes, and with a link transmission rate 26 Mbps an end-to-end propagation delay of 22.1 ms, what is the utilization
Answer:
for the 5 segments, the utilization is 3.8%
Explanation:
Given the data in the question;
segment size = 1090 bytes
Receiver window size = 5,718 bytes
Link transmission rate or Bandwidth = 26 Mbps = 26 × 10⁶ bps
propagation delay = 22.1 ms
so,
Round trip time = 2 × propagation delay = 2 × 22.1 ms = 44.2 ms
we determine the total segments;
Total segments = Receiver window size / sender segment or segment size
we substitute
Total segments = 5718 bytes / 1090 bytes
Total segments = 5.24587 ≈ 5
Next is the throughput
Throughput = Segment / Round trip
Throughput = 1090 bytes / 44.2 ms
1byte = 8 bits and 1ms = 10⁻³ s
Throughput = ( 1090 × 8 )bits / ( 44.2 × 10⁻³ )s
Throughput = 8720 bits / ( 44.2 × 10⁻³ s )
Throughput = 197.285 × 10³ bps
Now Utilization will be;
Utilization = Throughput / Bandwidth
we substitute
Utilization = ( 197.285 × 10³ bps ) / ( 26 × 10⁶ bps )
Utilization = 0.0076
Utilization is percentage will be ( 0.0076 × 100)% = 0.76%
∴ Over all utilization for the 5 segments will be;
⇒ 5 × 0.76% = 3.8%
Therefore, for the 5 segments, the utilization is 3.8%

Write a program get_price.py with a function get_price() that takes a dictionary of fruits as an argument and returns the name of the most expensive fruit. Each item of the dictionary includes: A key: the name of the fruit A value: the price of the fruit.
Answer:
The program is as follows:
def get_price(fruits):
AllPrice = fruits.values()
value_iterator = iter(AllPrice)
mostExpensive = next(value_iterator)
for item in fruits:
if fruits[item]>=mostExpensive:
mostExpensive = fruits[item]
fruitName = item
print(fruitName)
fruits = {}
n = int(input("Number of Fruits: "))
for i in range(n):
name = input("Fruit name: ")
price = int(input("Fruit price: "))
fruits[name] = price
get_price(fruits)
Explanation:
This defines the get_price function
def get_price(fruits):
This gets all price in the dictionary fruit
AllPrice = fruits.values()
This passes the values to a value iterator
value_iterator = iter(AllPrice)
This initializes mostExpensive to the first price in the dictionary
mostExpensive = next(value_iterator)
This iterates through the elements of the dictionary
for item in fruits:
If current element is greater than or equals most expensive
if fruits[item]>=mostExpensive:
Set most expensive to the current element
mostExpensive = fruits[item]
Get the corresponding fruit name
fruitName = item
Print fruit name
print(fruitName)
The main begins here
This initializes the fruit dictionary
fruits = {}
This gets input for the number of fruits
n = int(input("Number of Fruits: "))
This is repeated for every inputs
for i in range(n):
Get fruit name
name = input("Fruit name: ")
Get fruit price
price = int(input("Fruit price: "))
Append name and price to dictionary
fruits[name] = price
Call the get_price function
get_price(fruits)

In the welding operations of a bicycle manufacturer, a bike frame has a long flow time. The set up for the bike frame is a 7 hour long operation. After the setup, the processing takes 6 hour(s). Finally, the bike frame waits in a storage space for 7 hours before sold. Determine the value-added percentage of the flow time for this bike frame. Round your answer to the nearest whole number for percentage and do NOT include the "%" sign in the answer. For example, if your answer is 17.7%, please answer 18. If your answer is 17.4%, please answer 17. No "%" sign. No letter. No symbols. No explanation. Just an integer number.
Answer:
Bike Frame Flow Time
The value-added percentage of the flow time for this bike frame is:
= 46.
Explanation:
a) Data and Calculations:
Bike Frame Flow Time:
Setup time = 7 hours
Processing time = 6 hours
Storage time = 7 hours
Flow time of the bike frame = 13 hours (7 + 6)
Value-added percentage of the flow time for this bike frame = 6/13 * 100
= 46%
b) Flow time represents the amount of time a bicycle frame spends in the manufacturing process from setup to end. It is called the total processing time. Unless there is one path through the process, the flow time equals the length of the longest process path. The storage time is not included in the flow time since it is not a manufacturing process.

cloud offers better protection compare to on premise?
Why is cloud better than on-premise? Dubbed better than on-premise due to its flexibility, reliability and security, cloud removes the hassle of maintaining and updating systems, allowing you to invest your time, money and resources into fulfilling your core business strategies.
The security of the cloud vs. on-premises is a key consideration in this debate. Cloud security controls have historically been considered less robust than onprem ones, but cloud computing is no longer a new technology. . A company running its own on-premises servers retains more complete control over security.

Explain the purpose of the open() and close() operations.
Answer:
The open() operation notifies the system that the named file is about to become active. The close() operation notifies the system that the named file is no longer in active use by the user who issued the close operation.
Create union integer with members char c, short s, int i and long b. Write a program that inputs the values of type char, short, int, and long and stores the values in union variables of type union integer. Each union variable should be printed as a char, a short, an int and a long. D the values always print correctly? Also create pseodocode or flowchart.
Here is the feedback that I received when I originally turned this in:
I have the following concerns: You need to save your program file with a .c extension. You should declare your union above the main module and then utilize it from within this portion. You have declared the union and then created a function definition prior to entering the main() function.
Here is the original code provided by homework help: Thanks in advance
#include
union myUnion {
char c;
short s;
int i;
long l;
};
void print(myUnion u) {
printf("As a character: %c\n", u.c);
printf("As a short: %hd\n", u.s);
printf("As an int: %d\n", u.i);
printf("As a long: %ld\n\n", u.i);
}
int main() {
myUnion u;
printf("Please enter a character: ");
scanf("%c", &(u.c));
print(u);
printf("Please enter a short: ");
scanf("%hd", &(u.s));
print(u);
printf("Please enter an int: ");
scanf("%d", &(u.i));
print(u);
printf("Please enter a long: ");
scanf("%ld", &(u.l));
print(u);
return 0;
Answer:
The updated program in C is as follows:
#include <stdio.h>
union myUnion{ char c; short s; int i; long l; };
int main(){
union myUnion inputs;
printf("Character: "); scanf("%c", &inputs.c);
printf("Output: %c", inputs.c);
printf("\nShort: "); scanf("%hd", &inputs.s);
printf("Short: %hd", inputs.s);
printf("\nInteger: "); scanf("%d", &inputs.i);
printf("Output: %d", inputs.i);
printf("\nLong: "); scanf("%ld", &inputs.l);
printf("Long: %ld", inputs.l);
return 0;
}
The pseudocode is as follows:
Function union myUnion {
character; short; int; long
}
main() {
myUnion inputs;
Input inputs.c; Print inputs.c
Input inputs.s; Print inputs.s
Input inputs.i; Print inputs.i;
Input inputs.l; Print inputs.l
}
Explanation:
This defines the union function
union myUnion{ char c; short s; int i; long l; };
The main begins here
int main(){
This calls the union function to main
union myUnion inputs;
This prompts and gets input for character variable
printf("Character: "); scanf("%c", &inputs.c);
This prints the character input
printf("Output: %c", inputs.c);
This prompts and gets input for short variable
printf("\nShort: "); scanf("%hd", &inputs.s);
This prints the short input
printf("Short: %hd", inputs.s);
This prompts and gets input for integer variable
printf("\nInteger: "); scanf("%d", &inputs.i);
This prints the integer input
printf("Output: %d", inputs.i);
This prompts and gets input for long variable
printf("\nLong: "); scanf("%ld", &inputs.l);
This prints the long input
printf("Long: %ld", inputs.l);
return 0;
}
2.13 LAB: Branches: Leap Year
A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the
difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The
requirements for a given year to be a leap year are:
1) The year must be divisible by 4
2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400
Some example leap years are 1600, 1712 and 2016.
Write a program that takes in a year and determines whether that year is a leap year.
Ex If the input is
1712
the output is
1712 13 leap year.
Ex If the nouts
1913
the outoutis
1913 not leap year.
Written is Coral Language
Answer:
integer userInput
userInput = Get next input
if userInput % 400 == 0
Put userInput to output
Put " is a leap year" to output
else
if userInput % 4 == 0
Put userInput to output
Put " is a leap year" to output
else
Put userInput to output
Put " is not a leap year" to output
Explanation:
I don't know what is so special about Coral but here we go. I couldn't find and IDE that supported Coral so I just used their Coral simulator on their website. The first if statement on line 5 determines if the number is divisible by 400. If so, the leap year is on a century year e.g 1900 1800. If not, the else statement will be executed and the second if statement will execute. If the number is divisible by 4, it is a leap year. If not, the else statement gets executed in which case the number was not a century leap year or a leap year. After that the program terminates.
Hope this helped :) If it didn't let me know and I do my best to find out what went wrong.
Have a good day :)
So, I need to use an external mic for my phone, but the problem is that I need a "dual mic adapter". My dad gave me an "audio splitter" instead. Can I use the audio splitter instead in order to connect the external mic to my phone???
But you can't use this device alone to connect two microphones to your USB C port and expect it to have usable volume. So the description is somewhat misleading ...
After reading the background, please work on the following problem: a. The source process reads information from a file (Therefore, you need to prepare a small text file for testing purpose). b. The source process calls fork() to create the filter process. c. The filter process reads information from the source process (passed via an anonymous pipe), converts the uppercase characters to lowercase ones and vice versa, and then prints out the converted characters to the screen.
Answer:
Explanation:
The following code is written in Java. It has the main method (source process) and a function called fork() which contains the filter process as described in the question. fork() takes in the file information as a parameter and prints out the information to the screen. The test can be seen with the output in the attached image below.

Use the tables below to show the difference between the results of a natural join, an equijoin (with PROF_CODE = 2) and a full outer join. Provide the resulting table of each join
Answer:
Code:
CREATE TABLE student (
stu_code INTEGER PRIMARY KEY,
prof_code INTEGER
);
INSERT INTO student VALUES (100278,null);
INSERT INTO student VALUES (128569,2);
INSERT INTO student VALUES (512272,4);
INSERT INTO student VALUES (531235,2);
INSERT INTO student VALUES (531268,null);
INSERT INTO student VALUES (553427,1);
CREATE TABLE professor (
prof_code INTEGER PRIMARY KEY,
dept_code INTEGER
);
INSERT INTO professor VALUES (1,2);
INSERT INTO professor VALUES (2,6);
INSERT INTO professor VALUES (3,6);
INSERT INTO professor VALUES (4,4);
The SQL NATURAL JOIN is a type of EQUI JOIN and is structured in such a way that, columns with the same name of associated tables will appear once only. In our Example, Prof_code will appear only once and it will be matched in both the table;
SELECT * FROM Student natural join Professor on student.prof_code=Professor.prof_code ;
Stud_code Prof_code Dept_code
128569 2 6
512272 4 4
531235 2 6
553427 1 2
EQUI JOIN performs a JOIN against equality or matching column(s) values of the associated tables and an equal sign (=) is used as a comparison operator in the where clause to refer to equality. In our example, it will only show the result with prof_code=2 from the natural join result.
SELECT * FROM Student join Professor on student.prof_code=Professor.prof_code where student.prof_code=2;
Stud_code Prof_code Prof_code Dept_code
128569 2 2 6
531235 2 2 6
In SQL the FULL OUTER JOIN combines the results of both left and right outer joins and returns all (matched or unmatched) rows from the tables on both sides of the join clause.
SELECT * FROM professor full outer join student on professor.prof_code=student.prof_code ;
Stud_code Prof_code Prof_code Dept_code
100278
128569 2 2 6
512272 4 4 4
531235 2 2 6
531268

553427 1 1 2
Research via the internet and find an article in the news regarding wireless hacking, hardware hacking, or other security breach. As security and IT changed so rapidly, your article should be no older than 2007 (i.e. Less than 5 years old). Summarize the article using at least 500 words.
Hi, I provided some explanation of key terms.
Explanation:
Wireless hacking: basically the term refers to any unethical activity carried over a radio wave-connected network (eg Internet or Wifi connection) that would provide unauthorized access to information.
Hardware hacking: On the other hand, hardware hacking involves resetting physical hardware with the objective of using it in a way not originally intended by the manufacturer.
The Curiosity Rover has recently landed on Mars and likes to send Twitter updates on its progress. If a tweet is posted 10 minutes after it was sent, how far is Curiosity from Earth? (Assume there is no network lag.)
Answer:
1.8 * 10^11 m
Explanation:
Given that :
Time taken for tweet to me posted after been sent, t = 10 minutes
t in seconds :
60 seconds = 1 minute
10 minutes = (10 * 60) = 600 seconds
Tweet sent will br transmitted at the speed of light, c = 3 * 10^8 m/s
Recall :
Speed = distance / time
Distance = speed * time
Distance of Curiosity from Earth = (3 * 10^8 * 600)
Distance of curiosity from earth = 1.8 * 10^11 m
Kamal plans to offer new, more favorable contracts to business customers who are now receiving a discount and use wireless services. Determine whether each customer should receive a new contract as follows:
a. In cell 15, enter a formula using the AND function that tests whether the Wireless value is equal to "Y" and whether the Discount value is equal to "Y".
b. Fill the range 16:118 with the formula in cell 15.
Solution :
'AND" operation is a logical operation and is used in logical connective combining two statements and in truth tables.
Using AND operation verifies whether the outcome P and Q is true only when both the P as well as Q are true. If one of the P or Q is not true, then outcome result will be false.
In the context, Kamal wishes to offer a new and more favorable contracts to the business customers who use a wireless services and receive a discount.
Therefore, using the AND operation of the customers as :
Customer Wireless Discount Outcome
A N N FALSE
B Y N FALSE
C N Y FALSE
D Y Y TRUE

Answer:
a. cout << Product ::name;
Explanation:
Computer software use different languages which helps user to initiate command. When a user initiates command the results are displayed according to input command. If product name is required as output then insert command should be product::name; this will display names of different products present in the system.
you are the network administrator for a college. wireless access is widely used at the college. you want the most secure wireless connections you can have. which of the following would you use?
A WPA
B WEP2
CWEP
D WPA2
Answer:
D. WPA2
Explanation:
Required
Of the 4 options, which is the most secured?
WPA was created as a solution to the vulnerabilities in WEP/WEP2. Then, WPA was upgraded to WPA2.
WPA2 is the least vulnerable to hacks because for every user that is connected to the network through WPA2, a unique encryption is made available for such connection.
Hence, the most secure connection, of the 4 is WPA2.
