why SSTF disk scheduling is not practically feasible?
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.

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);
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; }
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.

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. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. Ex: If the input is: n Monday the output is: 1 n Ex: If the input is: z Today is Monday the output is: 0 z's Ex: If the input is: n It's a sunny day the output is: 2 n's Case matters. Ex: If the input is: n Nobody the output is: 0 n's n is different than N.
Answer:
The program in Python is as follows:
char = input("Character: ")[0]
string = input("String: ")
kount = string.count(char)
print(kount,char,end="")
if kount!=1:
print("'s")
Explanation:
This gets character input
char = input("Character: ")[0]
This gets string input
string = input("String: ")
This counts the occurrence of char in string
kount = string.count(char)
This prints the number of occurrence and the character
print(kount,char,end="")
This prints 's, if kount is other than 1
if kount!=1:
print("'s")

a. Bluetooth
b. Infared
c. NFC
d. Tethering
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.

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?
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.

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.

What is internet protocol?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.
