Free Front-End Development MCQ Questions and Answers — Questions and Answers
Question 1: This is the general term for anything that makes up a website, such as photos, videos, music, Word documents, and PDFs. <br> <br> Answer: Packets
- TRUE
- FALSE (Correct answer)
Correct answer: FALSE
The statement is FALSE. The general term for anything that makes up a website, such as images, videos, and documents, is typically referred to as 'web assets' or 'web content.' 'Packets' are small units of data that are transmitted over a network, not the content itself. Therefore, equating website content with packets is incorrect.
Question 2: Characteristics that define a node.
- Attributes
- Properties (Correct answer)
- Identities
- Methods
Correct answer: Properties
In programming, particularly within the Document Object Model (DOM), 'properties' are characteristics that define a node or object. They represent the data associated with an object, such as its value, text content, or dimensions. While 'attributes' are defined in HTML markup, 'properties' are the JavaScript representation of those attributes and other dynamic characteristics of an object.
Question 3: Actions can be carried out using javascript to change, add, or remove nodes from a document or to get/set properties for them.
- Clients
- Servers
- Properties
- Methods (Correct answer)
Correct answer: Methods
In JavaScript and the Document Object Model (DOM), 'methods' are actions or functions that can be performed on an object or node. These methods allow developers to programmatically manipulate the document structure, such as adding, removing, or changing nodes, as well as getting or setting their properties. They are essentially the behaviors an object can execute to interact with the document.
Question 4: A language for creating web clients that implement behaviors. Timings, animation, and server-side calls.
- Html
- Css
- JavaScript (Correct answer)
- Html Element
Correct answer: JavaScript
JavaScript is a high-level, interpreted programming language primarily used for creating interactive web clients. It enables dynamic behaviors like timings, animations, and making server-side calls (AJAX) directly within the user's browser, enhancing the user experience. While HTML structures content and CSS styles it, JavaScript adds the dynamic functionality and interactivity to web pages.
Question 5: An HTML, XHTML, or XML document is treated as a tree structure, with each node acting as an object representing a different page section. Any visible changes from manipulating the objects programmatically may subsequently be mirrored in how the document is displayed. It is a collection of protocols (language structures or means of communication), subroutine definitions (predefined instructions), and construction tools for application software.
- API (Application Programming Interface) (Correct answer)
- Document object
- Sdk (software Development Kit)
- Python library
Correct answer: API (Application Programming Interface)
The description accurately defines an API (Application Programming Interface), specifically the Document Object Model (DOM) API in the context of web development. An API is a set of defined protocols, routines, and tools for building software applications, allowing different software components to communicate and interact. The DOM is an API for HTML and XML documents, treating them as a tree structure of objects that can be manipulated programmatically.
Question 6: Protocols for communication specify how information should go across the internet. This is comparable to the transit systems allowing you to place an order, visit the store, and purchase items. This is comparable to a car or a bike in our scenario (or however else you might get around).
- Http
- TCP/IP (Correct answer)
- Web pages
- Dns
Correct answer: TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol) is the fundamental suite of communication protocols that define how data is transmitted over the internet. It provides the rules and standards for how information is broken into packets, addressed, transmitted, routed, and received, much like a transit system for data. HTTP, DNS, and web pages are built upon this foundational protocol suite.
Question 7: Not a computer language at all! To instruct a browser on structuring material is called markup (formatted list, paragraph, table, headers, in-line or block, etc.).
- Css
- JavaScript
- Html (Correct answer)
- Http
Correct answer: Html
HTML (Hyper Text Markup Language) is explicitly a markup language, not a programming language. Its purpose is to structure content on the web by using tags to define elements like paragraphs, headings, lists, and tables. It instructs the browser on how to display and organize content, rather than executing logical operations or algorithms like a programming language.
