- 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.

Discuss the OSI model's physical layer specifications when designing the physical network infrastructure for a new office.arrow_forwardIn 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.arrow_forward
- You are troubleshooting a network issue where an employee's computer cannot connect to the corporate network. The computer is connected to the network via an Ethernet cable that runs to a switch. Suspecting a possible layer 1 or layer 2 problem, you decide to check the LED status indicators on both the computer's NIC and the corresponding port on the switch. Describe five LED link states and discuss what each indicates to you as a network technician.arrow_forwardYou are a network expert tasked with upgrading the network infrastructure for a growing company expanding its operations across multiple floors. The new network setup needs to support increased traffic and future scalability and provide flexibility for network management. The company is looking to implement Ethernet switches to connect various devices, including workstations, printers, and IP cameras. As part of your task, you must select the appropriate types of Ethernet switches to meet the company's needs. Evaluate the general Ethernet switch categories you would consider for this project, including their features and how they differ.arrow_forwardYou are managing a Small Office Home Office (SOHO) network connected to the Internet via a fibre link provided by your Internet Service Provider (ISP). Recently, you have noticed a significant decrease in Internet speed, and after contacting your ISP, they confirmed that no issues exist on their end. Considering that the problem may lie within your local setup, identify three potential causes of the slow Internet connection, focusing on physical factors affecting the fibre equipment.arrow_forward
- Your organisation has recently installed a new network in a building it has acquired. As the network administrator, you have set up a dedicated telecommunications room to house all the rack-mounted servers, switches, and routers. To ensure optimal performance and longevity of the equipment, you need to monitor certain environmental factors in the room. Identify the environmental factors that should be monitored and explain why each is important to maintain the proper functioning of the telecommunications equipment.arrow_forwardYour organisation is preparing to move into a newly constructed office building that has never been occupied or wired for network services. As the network administrator, your manager has tasked you with designing a structured cabling plan that will support data, voice, and other network services across all building floors. The cabling plan must account for future expansion, efficient data transmission, and compliance with industry standards. Identify and explain the different subsystems you would include in the structured cabling scheme, following the ANSI/TIA/EIA 568 standard.arrow_forwardAs a technical advisor responsible for designing a network in a newly constructed building, you have decided to utilise twisted pair cables to efficiently deliver data and voice services. Given the specific requirements for connectivity in this setup, identify the appropriate connector types that can be used with twisted pair cables, explaining how each connector works in detail.arrow_forward
- In computer networks, communication between devices or nodes relies on predefined rules known as network protocols. These protocols ensure that data can be transmitted accurately and efficiently between different devices, even on separate networks or running different operating systems. Explain how a network protocol facilitates the transmission of data between nodes.arrow_forwardYou are part of the IT department at a large company, tasked with setting up a new branch office's networking infrastructure. The branch office must handle various types of traffic, including video conferencing, file sharing, and cloudbased business applications. The network will also need to prioritise certain types of traffic to ensure smooth video conferencing and efficient application performance. Due to budget constraints, the company plans to use physical and virtual systems to set up the network, balancing the cost and performance needs. Describe how you would approach the design and implementation of the networking infrastructure for this new branch office, ensuring it meets the company's needs for efficient application performance and traffic prioritisation.arrow_forwardTask 1: Abstract Class (15 Points) HybridCourse percentOfRemoteLearning: int +HybridCourse() +HybridCourse(courseName: String, sectiomNumber: int, instructorName: String, percentOfRemoteLearning: int) +getCapacity() int +getPercentOfRemoteLearning(): int +setPercentOfRemoteLearning (percentOfRemoteLearning: int): void +toString(): String Course -courseName: String - sectionNumber: int - instructorName: String - numberOfStudentsEnrolled: int #Course() #Course(courseName: String) #Course(courseName: String, sectionNumber: int, instructorName: String) +getCapacity(): int +get CourseName(): String +set CourseName(courseName: String): void +getSection Number(): int +setSection Number(section Number: int): void +getInstructorName(): String +setInstructorName(instructorName: String): void +getNumberOfStudentsEnrolled(): int +toString(): String - platform: String Online Course - meetingLink: String sectionNumber: int, + OnlineCourse() + OnlineCourse(courseName: String, instructorName: String,…arrow_forward
