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.

Answers

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.

d. Tethering

Answers

Answer:

The technologies that Ann will MOST likely use to connect the pedometer to her desktop to transfer her information to the website are:

a. Bluetooth

and

c. NFC

Explanation:

Bluetooth and NFC (Near Field Communication) are wireless technologies that enable the exchange of data between different devices.  Bluetooth operates on wavelength.  NFC operates on high frequency.  The security of NFC over Bluetooth makes it a better tool of choice.  NFC also operates on a shorter range than Bluetooth, enabling a more stable connection. NFC also enjoys a shorter set-up time than Bluetooth.  It also functions better than Bluetooth in crowded areas.  Tethering requires the use of physical connectors.  Infrared is not a connecting technology but wave radiation.

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.

Answers

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.

Queues can be represented using linear arrays and have the variable REAR that point to the position from where insertions can be done. Suppose the size of the array is 20, REAR=5. What is the value of the REAR after adding three elements to the queue?

Answers

Answer:

8

Explanation:

Queues can be implemented using linear arrays; such that when items are added or removed from the queue, the queue repositions its front and rear elements.

The value of the REAR after adding 3 elements is 5

Given that:

[tex]REAR = 5[/tex] --- the rear value

[tex]n = 20[/tex] --- size of array

[tex]Elements = 3[/tex] --- number of elements to be added

When 3 elements are added, the position of the REAR element will move 3 elements backward.

However, the value of the REAR element will remain unchanged because the new elements that are added will only change the positioning of the REAR element and not the value of the REAR element.

Chất xơ có nhiều trong thực phẩm nào?

Answers

Answer: rau củ quả đều có lượng chất xơ nhiều hơn so với các loại thực phẩn khác

Explanation:

Write a method, including the method header, that will receive an array of integers and will return the average of all the integers. Be sure to use the return statement as the last statement in the method. A method that receives an array as a parameter should define the data type and the name of the array with brackets, but not indicate the size of the array in the parameter. A method that returns the average value should have double as the return type, and not void. For example: public static returnType methodName(dataType arrayName[]) 3 The array being passed as a parameter to the method will have 10 integer numbers, ranging from 1 to 50. The average, avgNum, should be both printed in the method, and then returned by the method. To print a double with 2 decimal points precision, so use the following code to format the output: System.out.printf("The average of all 10 numbers is %.2f\n", avgNum);

Answers

Answer:

The method is as follows:

public static double average(int [] arrs){

    double sum = 0,avgNum;

    for(int i = 0;i<arrs.length;i++){

        sum+=arrs[i];

    }

    avgNum = sum/arrs.length;

    System.out.printf("The average of all numbers is %.2f\n", avgNum);

    return avgNum;

}

Explanation:

This defines the method

public static double average(int [] arrs){

This declares sum and avgNum as double; sum is then initialized to 0

    double sum = 0,avgNum;

This iterates through the array

    for(int i = 0;i<arrs.length;i++){

This adds up the array elements

        sum+=arrs[i];     }

This calculates the average

    avgNum = sum/arrs.length;

This prints the average to 2 decimal places

    System.out.printf("The average of all numbers is %.2f\n",

avgNum);

This returns the average to main

    return avgNum; }

why SSTF disk scheduling is not practically feasible?​

Answers

Answer:

There is a lack of predictability because of the high variance of response time. Additionally, SSTF may cause starvation of some requests. Starvation is possible for some requests as it favors easy to reach requests and ignores the far-away processes.

SSTF disk scheduling is not practically feasible because it makes an external call and is forced to wait for I/O to complete, thereby giving up its first-place position.

What is SSTF disk scheduling?

Shortest Seek Time First (SSTF) is a disc scheduling algorithm that is abbreviated as SSTF. Before moving the head away to service other requests, it selects the request that is closest to the current head location.

Because of the high variance in response time, there is a lack of predictability. Furthermore, SSTF may cause some requests to be denied. Some requests may experience starvation because the system prioritizes nearby requests and overlooks distant operations.

Therefore, because it makes an external call and is obliged to wait for I/O to complete, SSTF disc scheduling is not viable because it loses its first-place status.

The Internet Protocol (IP) is a protocol, or set of rules, that is used to route and address data packets so that they can travel across networks and arrive at their intended destination.

Data traveling across the Internet is split up into smaller slices known as packets.

Essentially, it enables linked gadgets to interact with one another despite differences in internal processes, structure, or design.

Network protocols enable easy communication with people all over the world and thus play an important role in modern digital communications.

The Internet can be accessed by a wide range of computing devices. To send data over the Internet, all devices must use the Internet Protocol.

Thus, all the given device will use the Internet Protocol (IP) when sending data through the Internet.
