Priority Queue: If the items in the queue are related with a priority, then it is called priority queue. When inserting an item into the priority queue, the item is added with the priority. When removing an item from the priority queue, the item with higher priority is first removed. Then, based on the priority, the other items are removed. Priority queue can be implemented as an array, heap, or some other structure. Priority queue can be used as a queue. When inserting a number into the priority queue, the high priority to low priority can be given in the order they are inserting. That is, the first entered element should have the highest priority and the priority is decreased as the items are inserted further. So, by using the deletemaximum() function, the first inserted item is taken out first.

Task 2: Comparable Interface and Record (10 Points) 1. You are tasked with creating a Java record of Dog (UML is shown below). The dog record should include the dog's name, breed, age, and weight. You are required to implement the Comparable interface for the Dog record so that you can sort the records based on the dogs' ages. Create a Java record named Dog.java. name: String breed: String age: int weight: double + toString(): String > Dog + compareTo(otherDog: Dog): int > Comparable 2. In the Dog record, establish a main method and proceed to generate an array named dogList containing three Dog objects, each with the following attributes: Dog1: name: "Buddy", breed: "Labrador Retriever", age: 5, weight: 25.5 Dog2: name: "Max", breed: "Golden Retriever", age: 3, weight: 30 Dog3: name: "Charlie", breed: "German Shepherd", age: 2, weight: 22 3. Print the dogs in dogList before sorting the dogList by age. (Please check the example output for the format). • 4. Sort the dogList using…

The OSI (Open Systems Interconnection) model is a conceptual framework that standardises the functions of a telecommunication or computing system into seven distinct layers, facilitating communication and interoperability between diverse network protocols and technologies. Discuss the OSI model's physical layer specifications when designing the physical network infrastructure for a new office.

In a network, information about how to reach other IP networks or hosts is stored in a device's routing table. Each entry in the routing table provides a specific path to a destination, enabling the router to forward data efficiently across the network. The routing table contains key parameters determining the available routes and how traffic is directed toward its destination. Briefly explain the main parameters that define a routing entry.
