Step by step
Solved in 3 steps
- Interrupts are system wide events that stops the execution of a currently running process. Examples of interrupts include (but are not limited to) mouse clicks, process termination, key presses, etc. Some interrupts are considered as more important to be handled first then the others. For example, a hardware interrupt such as hard drive read operation has lesser priority than a memory read. In this way, the most appropriate data structure for representing of such events is the priority queue. Demonstrate by writing an algorithm or a flowchart how to insert the following interrupts in a heap so the highest priority element should move out first. Interrupts Priorities INT 0 100 INT 10 51 INT 11 52 INT 21 54Explain the concept of "execution flow."Please explain what you mean by "execution flow."
- Using JML(formal specification language) Write formal specifications of the following operations: An operation that takes two numbers and returns the maximum of the two.Vocabulary Task (C language) Natural language processing (NLP) is a field of artificial intelligence that seeks to develop the ability of a computer program to understand human language. Usually, the first step of an NLP system is to convert words into numeric codes. Thus, the system converts an input text into a sequence of numeric codes before any high-level analysis. This process is known as text preprocessing. We can only perform text preprocessing if we have a vocabulary of words and their associated numeric codes. Your task is to create a vocabulary of unique words for a given text file and assign a different number from 1 to N to each unique word, with N being the total number of unique words. You must perform this assignment so that the first word in alphabetical order gets the number 1, the second word in alphabetical order gets the number 2, and so on. A word is a sequence of letters (uppercase or lowercase). The file is composed of letters and white spaces (spaces, tabs,…Define execution time.
- Briefly explain parametersImplement Round Robin scheduling algorithm in C programming. NOTE: Please do not compute and print the average waiting time and the average turnaround time. You are required to compute these for each process and print these times for each process separately. Add comments in the code so that the code is understandable. Take input from the user: the number of processes, the time quantum and their CPU burst times for n number of processes. Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming. Assuming all the processes have arrived at time 0, please do not take arrival times as input from the user.c++ cosc 3360/6310 operating system consider the following process synchronization problem. an ice-cream store has a variety (k type of flavors) of ice creams being sold by n salespeople. if a sales person is available, the the customer is served; otherwise, the customers waits. using pseudo code. wrote a procedure using wait and signal operation for the sales people to execute and another on for the customers

Provide a formula to compute the latest start time for each subtask such that the deadline of the entire task can be satisfied. (Please type out the answer)Problem: UMLThis exercise is for a simplified supermarket cash register system. The normal procedure for using the cash register is as follows:• A customer arrives at the checkout with items to pay.• The cashier records the identification number of each item, as well as the quantity if it is greater than one.• The checkout displays the price of each item and its description.• When all purchases are recorded, the cashier signals the end of the sale.• The cash register displays the total purchases.• The customer chooses his method of payment:✓ cash: the cashier collects the money received; the cashier indicates the currency to be returned to the customer;✓ check: the cashier checks the creditworthiness of the customer by transmitting a request to an authorization center via the cashier;✓ credit card: a bank terminal is part of the cash register. It transmits an authorization request to an authorization center according to the type of card.• The cash register registers the sale and prints…What precisely does it mean to say that something is flowing via execution?
