The three basic types of control structures are sequential, selection and iteration. They can be combined in any way to solve a specified problem. Sequential is the default control structure, statements are executed line by line in the order in which they appear.
How long does it take to send a 15 MiB file from Host A to Host B over a circuit-switched network, assuming: Total link transmission rate
Answer:
The answer is "102.2 milliseconds".
Explanation:
Given:
Size of file = 15 MiB
The transmission rate of the total link= 49.7 Gbps
User = 7
Time of setup = 84.5 ms
calculation:
[tex]1\ MiB = 2^{20} = 1048576\ bytes\\\\1\ MiB = 2^{20 \times 8}= 8388608\ bits\\\\15\ MiB= 8388608 \times 15 = 125829120\ bits\\\\[/tex]
So,
Total Number of bits [tex]= 125829120 \ bits[/tex]
Now
The transmission rate of the total link= 49.7 Gbps
[tex]1\ Gbps = 1000000000\ bps\\\\49.7 \ Gbps = 49.7 \times 1000000000 =49700000000\ bps\\\\FDM \ \ network[/tex]
[tex]\text{Calculating the transmission rate for 1 time slot:}[/tex]
[tex]=\frac{ 49700000000}{7} \ bits / second\\\\= 7100000000 \ bits / second\\\\ = \frac{49700000000}{(10^{3\times 7})} \ in\ milliseconds\\\\ =7100000 \ bits / millisecond[/tex]
Now,
[tex]\text{Total time taken to transmit 15 MiB of file} = \frac{\text{Total number of bits}}{\text{Transmission rate}}[/tex]
[tex]= \frac{125829120}{7100000}\\\\= 17.72\\\\[/tex]
[tex]\text{Total time = Setup time + Transmission Time}\\\\[/tex]
[tex]= 84.5+ 17.72\\\\= 102.2 \ milliseconds[/tex]
RecursionexerciseCOP 3502; Summer2021We have gone through many examples in the class and those examples are available in the slides and uploaded codes. Try to test those codes and modify as you wish for getting more clarification.In additiontry the following:---------------------------------------------------------------------------------------------------------------------------------------1.What would be the output of the following recursive function if we call rec2(5)
Answer:
The output is:
1 2 3 4 5
Explanation:
Given
See attachment for code segment
Required
The output of rec2(5)
From the attached code segment, we have the following:
The base case: if (x==0){ return;}
The above implies that, the recursion ends when the value of x gets reduced to 0
The recursion:
rec2(x-1); ---- This continually reduces x by 1 and passes the value to the function
printf("%d ", x); This prints the passed value of x
Hence, the output of rec2(5) is: 1 2 3 4 5

____________________ are designed according to a set of constraints that shape the service architecture to emulate the properties of the World Wide Web, resulting in service implementations that rely on the use of core Web technologies (described in the Web Technology section).
Answer: Web services
Explanation:
Web service refers to a piece of software which uses a XML messaging system that's standardized and makes itself available over the internet.
Web services provides standardized web protocols which are vital for communication and exchange of data messaging throughout the internet.
They are are designed according to a set of constraints which help in shaping the service architecture in order to emulate the properties of the World Wide Web.
Answer:
The correct approach is "REST Services".
Explanation:
It merely offers accessibility to commodities as well as authorization to REST customers but also alters capabilities or sources.
With this technique, all communications are generally assumed to be stateless. It, therefore, indicates that the REST resource actually may keep nothing between runs, which makes it useful for cloud computing.(a) Define a goal for software product quality and an associated metric for that attribute. (b) Explain how you could show that the goal is validatable. (c) Explain how you could show that the goal is verifiable. 2. (a) Create a list of software product attributes and a list for software project attributes. (b) Rank these in the order of how difficult you consider them to be measured. (c) Discuss the reasons for your choices
LAB: Count characters - methods
Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string.
Ex: If the input is
n Monday
the output is
1
Ex: If the input is
Today is Monday
the output is
0
Ex: If the input is
n it's a sunny day
the output is
0
Your program must define and call the following method that returns the number of times the input character appears in the input string public static int countCharacters (char userChar, String userString)

Consider the following class in Java:
public class MountainBike extends Bicycle {
public int seatHeight;
public MountainBike(int startHeight,
int startCadence,
int startSpeed,
int startGear) {
super(startCadence, startSpeed, startGear);
seatHeight = startHeight;
}
public void setHeight(int newValue) {
seatHeight = newValue;
}
}
What is this trying to accomplish?
super(startCadence, startSpeed, startGear);
a. Four fields of the MountainBike class are defined: super, startCadence, startSpeed and startGear.
b. The constructor for the parent class is called.
c. A method of the MountainBike class named super is defined.
d. Three fields are defined for the MountainBike class as intances of the class named super.
Answer:
b. The constructor for the parent class is called.
Explanation:
In this case this specific piece of code is calling the constructor for the parent class. Since a MountainBike object is being created. This creation uses the MountainBike class constructor but since this is a subclass of the Bicycle class, the super() method is calling the parent class constructor and passing the variables startCadence, startSpeed, startGear to that constructor. The Bicycle constructor is the one being called by super() and it will handle what to do with the variables inputs being passed.

How many ways are there to arrange the letters in the word ALGORITHMS? Note, the letter arrangement does not have to spell a word in the dictionary, but the new word must contain all the letters and each letter can be used only once.
there are ten letters in the word, so for the first position we can choose out of 10 option.
no matter wich specific option we choose, we will have 9 letters left for the 2nd letter.
and 8 for the third place.
...
when we will have used up 9 of 10 letters, there will be only one option for the last place.
the number of possible decision-paths is therefore given by this expression:
10*9*8*7*6*5*4*3*2*1
wich is 3,628,800
there are quite a few ways to rearrange 10 letters
The sorting method which commands entries in a going to head predicated on each character without regard to space as well as punctuation, therefore there are 3628800 ways.
The word 'ALGORITHMS' has 10 letters. There is no repeated letter so, the first Letter can hold 10 places if we start taking one letter at a time. The second can then hold nine positions, the third can hold eight, and so on.So, as [tex]\bold{ 10\times 9 \times 8.... \times 3 \times 2 \times 1 = 362,8800}[/tex] ways, we have such a total number of ways.

var num2 = 32;
var num1 = 12;
var rem=num2 % numi;
while(rem > 0)
{
num2 = num1;
num1 = rem;
rem = num2 % num1;
}
document.write(num1);
The output of the document.write statement at the end of this block is
Answer:
4
Explanation:
Given
The attached code segment
Required
The output
The first and second lines initialize num2 to 32 and num1 to 12, respectively.
Next, the remainder is calculated on line 3
[tex]rem = 32\%12[/tex]
[tex]rem = 8[/tex]
Then the while loop is repeated as long as rem > 0.
At first, we have:
[tex]num2 = 32[/tex]
[tex]num1 = 12[/tex]
[tex]rem = 8[/tex]
The first iteration gives:
[tex]num2 = 12[/tex]
[tex]num1 = 8[/tex]
[tex]rem = 12\%8 = 4[/tex]
Is 4 > 0? Yes; The loop is executed again.
This gives:
[tex]num2 = 8[/tex]
[tex]num1 = 4[/tex]
[tex]rem = 8\%4=0[/tex]
Is 0 > 0? No; The loop is executed
The last statement prints the last value of num1;
In the last loop, we have:
[tex]num1 = 4[/tex]
Hence, the output is 4

hub stake should always be provided with a lath stake so that the information about what the hub represents can be written on the lath stake True False
Answer:
True
Explanation:
To protect them from becoming disturbed by construction operations, hub stakes are placed on both sides of a roadway at a certain distance outside the work zone. The final stakes are connected to the hub stakes, which are used to write the essential information.
As a result, hub stakes are always accompanied with stakes.
A student registers for a course in a university. Courses may have limited enrollment i.e a student must
enroll atmost 9 credit hours, the registration process must include checks that places are available. Assume
that the student accesses an electronic course catalog to find out about available courses. Which design
model should be followed by this secenario? Draw any two UML diagrams.
Answer:
Follows are the complete question to the given question:
Explanation:
The UML scheme is a UML-based diagram intended to depict the system visually, together with its key actors, roles, activities, objects, and classes, to gather information the about system, change that, or maintain it.
Every complex process is better understood via sketches or pictures. These diagrams have a higher understanding effect. By glancing about, we notice that diagrams are not a new idea but are widely used in various business types. To enhance understanding of the system, we prepare UML diagrams. There is not enough of a single diagram to represent all aspects of the system. You can also create customized diagrams to satisfy your needs. Iterative and incremental diagrams are usually done.
There are two broad diagram categories and that they are broken into subclasses again:

Calculate how much disk space (in sectors, tracks, and surfaces) will be required to
store 300,000 120-byte logical records if the disk is fixed sector with 512 bytes/
sector, with 96 sectors/track, 110 tracks per surface, and 8 usable surfaces. Ignore
any file header record(s) and track indexes, and assume that records cannot span
two sectors.
It will be great if you could explain the answer to me. :)
Answer:

The amount of disk space in sectors that would be required to store 300,000 records is equal to 75,000 sectors.
Given the following data:
Number of records = 300,000.Size of each logical record = 120 byte.Number of bytes (sector) = 512.Number of sectors per track = 96.Number of tracks per surface = 110.How to calculate the required disk space?First of all, we would determine the number of logical records that can be held by each sector as follows:
Number of logical records per sector = 512/120
Number of logical records per sector = 4.3 ≈ 4.0.
Now, we can calculate the required disk space to store 300,000 records:
Disk space = 300,000/4
Disk space = 75,000 sectors.
For the tracks, we have:
Disk space in tracks = 75,000/96
Disk space in tracks = 781.25 ≈ 782.
Disk space in tracks = 782 tracks.
For the surfaces, we have:
Disk space in surfaces = 782/110
Disk space in surfaces = 7.10 ≈ 8.
Disk space in surfaces = 8 surfaces.

The manager of the Super Supermarket would like to be able to compute the unit price for products sold there. To do this, the program should input the name and price of an item per pound and its weight in pounds and ounces. Then it should determine and display the unit price (the price per ounce) of that item and the total cost of the amount purchased. You will need the following variables: ItemName Pounds Ounces PoundPrice TotalPrice UnitPriceYou will need the following formulas: UnitPrice = PoundPrice/16 TotalPrice = PoundPrice * (Pounds + Ounces/16)
Answer:
The program in Python is as follows:
name = input("Name of item: ")
PoundPrice = int(input("Pound Price: "))
Pounds = int(input("Weight (pounds): "))
Ounces = int(input("Weight (ounce): "))
UnitPrice = PoundPrice/16
TotalPrice = PoundPrice * (Pounds + Ounces/16)
print("Unit Price:",UnitPrice)
print("Total Price:",TotalPrice)
Explanation:
This gets the name of the item
name = input("Name of item: ")
This gets the pound price
PoundPrice = int(input("Pound Price: "))
This gets the weight in pounds
Pounds = int(input("Weight (pounds): "))
This gets the weight in ounces
Ounces = int(input("Weight (ounce): "))
This calculates the unit price
UnitPrice = PoundPrice/16
This calculates the total price
TotalPrice = PoundPrice * (Pounds + Ounces/16)
This prints the unit price
print("Unit Price:",UnitPrice)
This prints the total price
print("Total Price:",TotalPrice)
