A. RFID (Radio Frequency Identification) is the tracking method that provides real-time information.

RFID technology enables the identification and tracking of items in real-time by wirelessly transmitting data. The RFID system consists of RFID tags that contain unique identifiers and RFID readers that capture and process the tag information.

When an RFID tag comes within range of an RFID reader, the reader detects the tag and retrieves its data, such as product details, location, or status. This data is then immediately available for monitoring and analysis, providing real-time information about the tracked items.

Compared to other tracking methods mentioned, such as laser-etched barcodes, standard barcodes, or dot matrix applications, RFID offers the advantage of automatic and contactless data capture.

It eliminates the need for line-of-sight scanning or manual input, allowing for faster and more accurate tracking. The real-time nature of RFID enables businesses to have up-to-date visibility and control over their inventory, assets, or processes, enhancing efficiency and decision-making capabilities.

The correct answer is C. Byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.

Byte pair encoding is a data encoding technique that can be used to compress data, including text and images. The algorithm looks for pairs of characters that appear in the string more than once and replaces each instance of that pair with a corresponding character that does not appear in the string

Therefore, Unlike lossy compression techniques, such as JPEG, which discard some of the original data, byte pair encoding retains all of the information in the original string. This means that an encoded string can be restored to its original version without any loss of information.

The value of new_string can be obtained by using the replace() method in Python with the original string my_string and replacing the word "third" with "3rd".

In order to obtain the desired value of new_string as "roy came 3rd in the running race", you can use the replace() method in Python. The replace() method allows you to replace occurrences of a specified substring with another substring within a given string.

In this case, you can replace the word "third" in my_string with "3rd" by using the replace() method as follows:

python

Copy code

my_string = 'roy came third in the running race'

new_string = my_string.replace('third', '3rd')

The replace() method searches for the specified substring, which in this case is "third", within the my_string and replaces it with the specified replacement substring, which is "3rd". By assigning the result to new_string, you will obtain the desired output of "roy came 3rd in the running race".

The main goals of process scheduling algorithms in a modern multitasking operating system are as follows:Improving system performance: By selecting the right process scheduling algorithm, the system's performance can be improved. The algorithm should be designed in such a way that it can handle a large number of processes without negatively impacting the system's performance.

Keep track of resource allocation: The process scheduling algorithm should be designed in such a way that it can keep track of the resources allocated to each process and ensure that they are used efficiently.

Fairness: It is important to ensure that each process receives a fair share of the system's resources. If a process is given an unfair advantage, the system's performance will suffer.

Priority: The process scheduling algorithm should be able to prioritize the processes based on their importance.

Non-preemptive scheduling algorithms: In non-preemptive scheduling algorithms, once a process has been allocated the CPU, it will continue to execute until it either completes or blocks for some reason. In this algorithm, the CPU is not allocated to a new process until the currently running process completes. This algorithm is easy to implement but can lead to poor system performance if a long-running process is allocated the CPU.

Preemptive scheduling algorithms: In preemptive scheduling algorithms, a process can be interrupted and its execution suspended if a higher-priority process is ready to run. The preemptive algorithm has a higher system overhead but can achieve better performance by giving high-priority processes more CPU time to complete.The average turnaround time and average waiting time can be calculated for each scheduling algorithm as follows:

Priority scheduling: Average turnaround time = (16+11+12)/3 = 13.

Average waiting time = ((16-0)+(11-1)+(12-2))/3 = 8/3 = 2.67

First-come, first-served: Average turnaround time = (16+22+26)/3 = 21.33.

Average waiting time = ((16-0)+(22-4)+(26-8))/3 = 34/3 = 11.33

Round robin: Average turnaround time = (16+22+26)/3 = 21.33.

Average waiting time = ((0+2+4)+(17+19+22)+(26-2-8))/3 = 20/3 = 6.67.

In this lab, you declare and initialize constants in a C program. The program, which is saved in a file named calculate_age.c, calculates your age in the year 2050. In order to calculate your age in the year 2050, we need to know the current year.

We declare a constant called CURRENT_YEAR and initialize it to the current year using the time library in C. We then prompt the user to enter their birth year, which we store in a variable called birth_year. We subtract the birth year from the current year to get the user's age. Finally, we add the difference between 2050 and the current year to the user's age to get their age in the year 2050. We store this value in a variable called age_2050 and print it out to the user. Here is the code:`

``#include #include int main() {  const int CURRENT_YEAR = 2021;  int birth_year, age, age_2050;  printf("Enter your birth year: ");  scanf("%d", &birth_year);  age = CURRENT_YEAR - birth_year;  age_2050 = age + (2050 - CURRENT_YEAR);  printf("Your age in 2050: %d", age_2050);  return 0;}```This program demonstrates how to declare and initialize constants in C, as well as how to use variables and basic arithmetic operations to perform a simple calculation.
