1.List the various client-side scripting languages.

Client-side scripting languages are programming languages that run on the

user's web browser rather than on the web server. They are used to enhance
the functionality and interactivity of web pages. Here are some of the
popular client-side scripting languages:

1. JavaScript: Widely used for web development, JavaScript is a versatile

language that allows developers to create dynamic and interactive
content.
2. HTML/CSS: While not traditional programming languages, HTML
(Hypertext Markup Language) and CSS (Cascading Style Sheets) are
essential for client-side web development. HTML structures the
content, and CSS is used for styling.
3. TypeScript: A superset of JavaScript, TypeScript adds static typing to
the language, making it easier to catch errors during development.
4. CoffeeScript: A concise and elegant language that compiles into
JavaScript. It aims to make code more readable and maintainable.
5. Dart: Developed by Google, Dart is a language that can be compiled
to JavaScript. It is often used with the Flutter framework for building
cross-platform mobile applications.
6. ActionScript: Traditionally used for Adobe Flash development,
ActionScript is an object-oriented language. However, Flash is
becoming obsolete, and the usage of ActionScript has decreased.
7. VBScript: A scripting language developed by Microsoft, primarily used
with Internet Explorer. Its usage has declined, and it is not as widely
supported as JavaScript.
8. JScript: Microsoft's implementation of ECMAScript, similar to
JavaScript. It was commonly used in Internet Explorer but has been
largely replaced by JavaScript.

2. What is “this” keyword in JavaScript?
const person = {
firstName: "John",
lastName : "Doe",
id : 5566,
fullName : function() {
return this.firstName + " " + this.lastName;
}
};
In JavaScript, the this keyword refers to an object.

Methods like call(), apply(), and bind() can refer this to any object

3. What is Search Engine Optimization(SEO)?

4. List the various dialogue boxes in JavaScript.

5. Write a JavaScript function to find sum of first natural numbers.

// Javascript program to find sum of first
// n natural numbers.
function findSum(n) {
let sum = 0;
 for (let i = 1; i <= n; i++)
sum = sum + i;
return sum;
}

// Driver code
const n = 5;
console.log(findSum(n));
6. What do you mean by search engine?
A search engine is a web-based tool or software application designed to help
users find information on the internet. Search engines utilize algorithms to
search and retrieve data from various websites, databases, and other online
sources based on the user's query or search terms. The primary purpose of a
search engine is to present relevant and organized results to users in response
to their search queries.
Google is the most widely used search engine globally, but there are others such
as Bing, Yahoo, and specialized search engines focused on specific types of
content (e.g., image search, video search). Search engines play a crucial role in
facilitating access to information on the internet and have become an integral
part of the daily online experience for users worldwide.
7. How do search engine work?
Search engines work through a series of complex processes involving web
crawling, indexing, and ranking algorithms
8. Define Name Server.
A Name Server (or nameserver) is a crucial component of the Domain Name System
(DNS), which is a decentralized system that translates human-readable domain
names into IP addresses. Domain names, like "www.example.com," are easier for
people to remember, but computers communicate using IP addresses.
Name Servers store and manage DNS records, providing information about the
domain, such as its associated IP addresses, mail servers, and other resources.
When a user enters a domain name in a web browser or attempts to send an email,
the Name Server is responsible for resolving that domain name to the
corresponding IP address or other relevant information.

There are two main types of Name Servers:

1. Authoritative Name Server

2. Recursive Name Server
9. What is DNS?
Domain Name System (DNS) is a hostname for IP address translation service.
DNS is a distributed database implemented in a hierarchy of name servers. It
is an application layer protocol for message exchange between clients and
servers. It is required for the functioning of the Internet
Domain names, like "www.example.com," are easier for people to remember,
but computers communicate using IP addresses.

3. What is web hosting? Discuss the different types hosting packages in detail.
Web hosting is a service that allows individuals and organizations to make
their websites accessible on the internet. When you create a website, you
need a place to store and make your web pages and files available for
visitors. Web hosting providers offer server space, resources, and other
essential services to host your website and make it accessible to users
worldwide.

Here are different types of web hosting packages:

1.Shared Hosting:
 a. Description: In shared hosting, multiple websites share
resources on the same server. Each customer has a limit on the
resources they can use, such as disk space, bandwidth, and
databases.
b. Pros: Cost-effective, easy to set up, suitable for small websites
and beginners.
c. Cons: Shared resources can lead to performance issues if other
websites on the server experience high traffic.
2.Virtual Private Server (VPS) Hosting:
a.Description: VPS hosting uses virtualization technology to create
isolated virtual servers on a physical server. Each VPS operates
independently with its own dedicated resources.
b.Pros: More control and customization than shared hosting, better
performance and reliability.
c.Cons: More expensive than shared hosting, may require more
technical knowledge for management.
3Dedicated Hosting:
d. Description: With dedicated hosting, you get an entire physical
server exclusively for your website. This provides maximum
performance, control, and customization options.
e. Pros: High performance, full control over server settings,
suitable for large websites and applications.
f. Cons: Higher cost, requires server management skills, may be
overkill for small websites.
4. Cloud Hosting:
a. Description: Cloud hosting utilizes a network of interconnected
virtual servers that can scale resources dynamically based on
demand. It offers flexibility and scalability.
b. Pros: Scalability, flexibility, and reliability. Pay-as-you-go pricing
model.
c. Cons: Costs can increase based on usage, may require
understanding of cloud services.
5. Managed WordPress Hosting:
a. Description: Tailored for WordPress websites, this hosting type
includes specialized features for WordPress optimization,
security, and performance.
b. Pros: Simplifies WordPress management, automatic updates,
enhanced security.
c. Cons: Can be more expensive than shared hosting, may have
limitations for non-WordPress websites.
6. Reseller Hosting:
a. Description: Reseller hosting allows individuals or businesses to
resell hosting services. Resellers purchase hosting plans in bulk
and sell them to their clients.
 b. Pros: Potential for profit by reselling hosting services, ability to
manage multiple hosting accounts.
c. Cons: Requires business management skills, relies on the
hosting provider's infrastructure.
7. Colocation Hosting:
a. Description: Colocation hosting involves renting space in a data
center to place your own server hardware. You are responsible
for maintaining and managing the server.
b. Pros: Full control over hardware, high security, can be cost-
effective for large-scale operations.
c. Cons: Requires technical expertise, higher upfront costs,
responsibility for maintenance.

7.Write a JavaScript program to find largest among five numbers.
function findLargestAmongFive(num1, num2, num3, num4, num5) {
// Initialize a variable to store the largest number
let largest = num1;

// Compare with the remaining numbers

if (num2 > largest) {
largest = num2;
}

if (num3 > largest) {

largest = num3;
}

if (num4 > largest) {

largest = num4;
}

if (num5 > largest) {

largest = num5;
}

// Print the result

 console.log("The largest number is: " + largest);
}

// Example: Find the largest among 5, 10, 8, 15, and 12

findLargestAmongFive(5, 10, 8, 15, 12);
