Introduction to Web Development Interview Questions
Web developments broadly refer to the tasks associated with developing web pages for hosting via the internet or intranet. The web development process includes web designing, content development, client-side/ server-side scripting, and network security configuration.
The web development hierarchy is as follows.
- Client-side scripting
- Server-side scripting
- Database technology
Client-Server Architecture
The client is the service’s receiving end or the service or the requestor of the service in a client/server model type of system. This client is most often located on another system or computer which can be accessed over the network.
The server is a computer, device, or program that manages network resources. Servers are often called dedicated because they do hardly any other tasks besides their server tasks.
Client/server architecture is a computing model in which the server hosts, delivers, and manages most of the resources and services to be consumed by the client. This type of architecture has one or more client computers connected to a central server over a network or internet connection. This system shares computing resources.
The client-server architecture is also known as a network computing model or client/server network because all the requests and services are delivered over the web.
Website Architecture
A website is a collection of publicly accessible, interlinked web pages that share a single domain name. Websites can be created and maintained by an individual, group, business, or organization to serve various purposes.
Website architecture is the planning and design of a website’s technical, functional, and visual components before it is designed, developed, and deployed. It is used by website designers and developers to design and develop a website.
Web Development Types of Website
- Static websites: Also known as flat or stationary websites. They are loaded on the client’s browser as precisely as stored on a web server. The user can use only information but cannot modify or interact with the data. Static websites are created using superior HTML and made only when information is no more required to be changed.
- Dynamic websites: Dynamic websites show different information at different points in time. It is possible to change a portion of a web page without loading the entire web page. It has been made possible using AJAX technology.
Web page anatomy
A website consists of the following components.
- Containing block: A container is primarily the body tag of a page, which is all div tags.
- Logo: The logo defines the identity of the website.
- Navigation: The site’s navigation system should be easy to find and use.
- Content: The content on the website should be relevant to the purpose of the website.
- Footer: Usually contains copyright, contract, and legal information, as well as a few links to the main section of the website.
- Whitespace: It refers to an area that is not covered by type or illustrations.
Knowing all the terms lets you understand the process of web development. It involves all the steps that are necessary to take to build an attractive, practical, and responsive website.
For a successful web developer, one should have the following skills
- Thorough understanding of the client and server-side scripting.
- Testing cross-browser inconsistencies.
- Conduction observational user testing,
- Programming interaction with JavaScript, PHP, and JQuery.
To publish a website, you must have the following prerequisites.
- Web development software: used for building web pages for your website. E.g., WordPress, Dreamweaver.
- Internet connection: required to access the remotely located web server.
- Web server: actual location where your website resides on.

6. What is difference between <window.onload> and <OnDocumentReady>?
