java program For this question, the server contains the id, name and cgpa of some Students in a file. The client will request the server for specific data, which the server will provide to the client. Server: The server contains the data of some Students. For each student, the server contains id, name and cgpa data in a file. Here's an example of the file: data.txt101 Saif 3.52201 Hasan 3.81.... Create a similar file in you server side. The file should have at least 8 students. The client will request the server to provide the details (id, name, cgpa) of the Nth highest cgpa student in the file. If N's value is 1, the server will return the details of the student with the highest cgpa. if N's value is 3, the server will return the details of the student with the third highest cgpa. If N's value is incorrect, the server returns to the client: "Invalid request". Client: The client sends the server the value of N, which is an integer number. The client takes input the value of N…
I may need help with this project: A combined cycle gas turbine power station requires a webbased system to manage the storage and installation of spare parts and the acquisition of new parts from the Central Storage Warehouse (the CSW). The powerstation maintains an inventory of all the parts it owns comprising: part name, description and specification. There are many copies of some parts – each part has a unique ID, known as an asset tag number. The asset tag number is used when there is damage to particular parts. The power station also keeps a catalogue of all the possible spare parts types used.Only registered maintenance engineers and team leaders are allowed to install and repair parts on the plant. Maintenance engineers and team leaders can use the parts catalogue tosearch for part types and can also search the parts inventory. Maintenance engineers work in teams, currently: electrical, mechanical and environmental. Each team has its own team lead. However, the system needs to…
Smart" Internet of Things, e.g., smartphones or smart cars, are smart because devices are equipped with sensors. [ True / False ] All smartphones and most IoTs have a small database package embedded in themselves. The embedded database package is called mySQL. [ True / False ] XCode Swift does not care about the types of data. [ True / False ] Swift is an object-oriented programming language. [True / False ] In Swift, any variables can be simply used without having to declare them first. [True / False ] In Swift, functions can receive a function as an argument. [True/False] In Swift, functions can return another function as a complete argument. [True/False] Ultrasonic distance sensor is an active sensor [ True / False ] Most sensors themselves do not send their data to another outside. In such cases, (9) _______ can be used, which has GPIO pins to wire with sensors in two pinout modes: (10) _________ mode and (11) ______ mode. Fill in the blank.

Next.js Web API Create a words-app directory then create a Next.js 13.3 application inside words-app that implements the following API to manage multiple collections of words.1. Data is provided to you in words.json. The file contains an array of almost every word in the (American) English language. Copy that file to words-app/data/words.json.2. Add an endpoint to search for a certain number of words using a query text. The number of matching words is selected at random and returned. Return 10 words when the number of words is not provided. You should return at most 100 words per request.3. Add an endpoint to read all collections.4. Add an endpoint to read all words in a collection, add a word to a collection, and delete a word from a collection.5. You should validate all parameters provided by the user to the API and respond with an error (4xx) for invalid requests, such as an invalid parameter value, attempting to delete a non-empty collection, or attempting to delete a word from a…
