- When added to a web browser, how do add-on extensions function technically?TRUE OR FALSE JavaScript codes are invisible in the client browserMass Downloader Objectives: 1. Learn how to Retrieve objects over an HTTP connection. 2. Learn how to extract links from and an HTML file. Equipment and Software Tools Required: 1. PYTHON 2. urllib module 3. regex module Introduction: In some cases, you reach a website that has a list of objects (links) you want to download. This could be a course website with a list of the slides in PDF format. Therefore, you can use an application or browser extension that provides mass or batch downloading, such as Flashget and Chrono Download Manager. Those applications/extensions extract all links from the HTML file, give you the option to select the ones to download, and it will download all selected objects. In this lab exercise, you are going to write a script that will work as a mass downloader. Requirements In this exercise, the learner should write a mass downloader script. The script should download all links of a certain type from a given website. Therefore, the script should do the…
- you need to create a web server in Racket. E.g. you can create a web server that asks for the name surname and grade of a student and displays the resultDesign and implement an application that maintains the data for a simple social network. Each person in the network should have a profile that contains the person’s name, an image(Optional), current status(Online, offline, busy,...), and a list of friends. Your application should allow a user to join the network, leave the network, create a profile, modify the profile, search for other profiles, and add and remove friends. Reference: Data Structures and Abstractions with Java, Frank M. Carrano, 4th Edition, Pearson, 2015. You can use any data structure you have learned and written so far. DO NOT USE ANY JAVA to import data structures! (Except arrays) Use your own data structures that you wrote by yourself. Use at least a hash table or a dictionary. You need at least 2 data structures: One for profiles and one for the list of the friends of those profiles. You need to implement CRUD: C= Create: Add profile- Add friends R= Read: Read the information of a profile - Search for other…Technically, how do add-on extensions work on a web browser?

- The Pizza Ordering System allows the user of a web browser to order pizza for home delivery. To place an order, a shopper searches to find items to purchase, adds items one at a time to a shopping cart, and possibly searches again for more items. When all items have been chosen, the shopper provides a delivery address. If not paying with cash, the shopper also provides credit card information. The system has an option for shoppers to register with the pizza shop. They can then save their name and address information, so that they do not have to enter this information every time that they place an order. a.
