Give examples of applications that access files by each of the following methods:
+ Sequentially.
+ Random.

Answers

Answer 1

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.

Suppose we can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. We can redeem six coupons for one chocolate bar from the machine. This means that once you have started buying chocolate bars from the machine, you always have some coupons. We would like to know how many chocolate bars can be eaten if we start with N dollars and always redeem coupons if we have enough for an additional chocolate bar.For example, with 6 dollars we could consume 7 chocolate bars after purchasing 6 bars giving us 6 coupons and then redeeming the 6 coupons for one bar. This would leave us with one extra coupon. For 11 dollars, we could consume 13 chocolate bars and still have one coupon left. For 2 dollars, we could have consumed 14 chocolate bars and have two coupons left.Write a program that inputs a value for N and outputs how many chocolate bars we can eat and how many coupons we would have left over. Use a loop that continues to redeem coupons as long as there are enough to get at least one chocolate bar.

Answers

Answer and Explanation:

Using JavaScript:

/* program should take N input which represents the dollar amount and output how many chocolate bars and how many coupons we have*/

function chocolatebar(dollars){

var dollaramt= dollars;

var i;

for(i=0; i <= dollaramt; i++){

i=i+6

?

Alert ("you have 1 extra chocolate bar");

:

Alert ("keep buying chocolate bars to get more coupons for a bonus chocolate bar")

The advantage of returning a structure type from a function when compared to returning a fundamental type is that a. the function can return multiple values b. the function can return an object c. the function doesn’t need to include a return statement d. all of the above e. a and b only

Answers

Answer:

The advantage of returning a structure type from a function when compared to returning a fundamental type is that

e. a and b only.

Explanation:

One advantage of returning a structure type from a function vis-a-vis returning a fundamental type is that the function can return multiple values.  The second advantage is that the function can return can an object.  This implies that a function in a structure type can be passed from one function to another.

During the data transmission there are chances that the data bits in the frame might get corrupted. This will require the sender to re-transmit the frame and hence it will increase the re-transmission overhead. By considering the scenarios given below, you have to choose whether the packets should be encapsulated in a single frame or multiple frames in order to minimize the re-transmission overhead.

Justify your answer with one valid reason for both the scenarios given below.

Scenario A: Suppose you are using a network which is very prone to errors.

Scenario B: Suppose you are using a network with high reliability and accuracy.

Answers

The packets would be encapsulated in single frame in scenario A. In scenario B, it should be in multi frames.

In scenario A, given that this network has been said to be prone to error, the packets should be encapsulated in single frames.

The reason for this is because, using a single frame helps to decrease error. We have been told already that it is prone to error. If you use the multi frame, there would be very high likelihood of errors occurring.

In scenario B, given that the network is accurate and very reliable, the best packet is the multi frame.

It would give a quicker transmission and the likelihood of errors occurring is also low.

Answers

Answer:

Replace /* Your solution goes here */ with the following expression

accelGravity = (G * M) / (distCenter *distCenter );

Explanation:

Required

Complete the code

The equivalent expression of (G * M) / (d^2) is:

(G * M) / (distCenter *distCenter );

The expression must be stored in accelGravity.

So, we have:

Planning the functions of a program means deciding beforehand that what are the functions of a program and what to try to do and when to try to, hierarchy Charts are often helpful In doing/knowing this all.

   Showing how the functions of a program relate to every other means what's the connection between two functions for instance if we have a hierarchical chart of a corporation member then we'll have the connection among the members of the team i.e., first, we'll have CEO, then Manager then team/ project lead then team members and by using hierarchical chart ready to " we will be able to identify the connection among them. during a similar way, we will have a relationship among the functions of a program using the hierarchical chart.

If Scheme were a pure functional language, could it include DISPLAY ? Why or why not?​

Answers

Answer:

When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.

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

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.

Write a program that repeatedly accepts as input a string of ACGT triples and produces a list of the triples and the corresponding amino acids, one set per line. The program will continue to accept input until the user just presses ENTER without entering any DNA codes.

The string is split into triples and checked against the dictionary. If a value exists the gene and amino acid is printed, otherwise an "Invalid Sequence" error is printed for that triple. The program has been tested and the output can be seen in the attached image below.
