Differences between server side scripting and client side scripting

Summary

This video from Knowledge 24 explores the distinction between server-side and client-side scripting in software development. It clarifies that server-side scripts require a web server for processing and are used for dynamic page creation and database connections, offering more security as the code is hidden from users. In contrast, client-side scripts are processed by the web browser, execute faster, and are less secure due to code visibility. The video provides examples of each, such as PHP and JavaScript, and discusses their applications, like website customization and form-filling interactions.

Keywords

💡Scripting

Scripting refers to the writing of scripts, which are sets of instructions or programs, particularly for webpages. In the context of the video, scripting is the core concept, as it differentiates between server-side and client-side scripting. The script defines how webpages behave and interact with users, and is essential for dynamic web content.

💡Server-side Scripting

Server-side scripting is a type of scripting that involves a web server for processing. It is used to create dynamic web pages and involves the server in the execution of scripts. The video explains that server-side scripts are processed on the server and are not visible to the user, making them more secure. Examples from the script include PHP, JSP, ASP, and Python.

💡Client-side Scripting

Client-side scripting is executed within the user's web browser and does not require interaction with the web server. It is used for immediate feedback and interactions on the webpage, such as form validation. The script mentions that client-side scripts are less secure as the code is visible to the user and execute on the web browser, with JavaScript and VBScript being common examples.

💡Web Server

A web server is a system that processes requests via HTTP, the basic protocol used to transfer information on the web. In the context of server-side scripting, the web server is essential for executing scripts and generating dynamic content. The video emphasizes that server-side scripting involves the web server, which can affect the speed and security of the web application.

💡Web Browser

A web browser is a software application for accessing, retrieving, and displaying content over the internet. It is the platform on which client-side scripts are executed. The video script explains that client-side scripting relies on the web browser for processing, which allows for faster execution but less security.

💡Database

A database is an organized collection of data. In the context of server-side scripting, databases are connected to and interacted with through scripts to store, retrieve, and manipulate data. The video mentions that server-side scripting is used for database connections, which is crucial for dynamic web applications that require data persistence.

💡Dynamic Pages

Dynamic pages are web pages whose content changes based on user interactions or data from a database. The video script explains that server-side scripting is used to create these pages, which can display different content to different users or change content in real-time.

💡Execution

In the context of scripting, execution refers to the running of scripts to perform their intended functions. The video script distinguishes between server-side and client-side execution, noting that server-side scripts are executed on the server, while client-side scripts are executed in the user's web browser.

💡Security

Security in scripting refers to the protection of the code and data from unauthorized access or tampering. The video script highlights that server-side scripts are more secure because the code is not visible to the user, whereas client-side scripts are less secure as the code is exposed to the user.

💡Back-end

The back-end of a web application refers to the server-side components, including the server, application, and database. The video script mentions that server-side scripting is used as a back-end technology, handling the logic and data processing that users do not directly interact with.

💡Front-end

The front-end of a web application is the part that users directly interact with, including the user interface and user experience. Client-side scripting is used for the front-end, as it enhances interactivity and provides immediate feedback to the user, as explained in the video script.

Transcripts

hello everyone welcome to the channel

knowledge 24 for software development we

need 15 languages and the script means

it's a set of instructions or programs

for webpages which is executed without

compilation we have two types of the

scripting server-side scripting and

second this client-side scripting so

many persons are very confused between

both of them so in to this lecture we

will discuss about differences between

server side scripting and client-side

scripting so the first differences

server-side scripting involves web

server for processing

but in client-side scripting it does not

interact with the web server it it was

web browser for processing and execution

then second is server-side scripting is

used for users browser makes a request

to the server means it is useful making

dynamic pages and request is sent to the

server through the web browser so this

is the request now in client-side

scripting all the codes reside on the

web browser so web browser is used for

the execution purpose now the car is

server-side scripting is used to connect

to the database but client-side

scripting is not used for the connection

with the database then Nexus server-side

scripting

execution on that server and the result

will be displayed on the web browser but

client-side scripting

execution and result both are produced

on the web browser now the Nexus server

side scripting

SATA is used for the accessing this

the late summer but thanks I did not use

for accessing the settings of web server

it's only for the existing the local

setting means users computer setting it

makes us by the client site

now the next differences server side

asleep its responses very slow because

the processing is done on the remote

computer meets on the web server by this

reason it's less consistent but inclined

sites will pick its responses very fast

because all the codings

decide on the web browser so execution

is on the web browser so it's really

fast now the next is server side is

simply is very secure because it's good

execution code is not visible to the

users means it is hide from the user

but in client side it is less secure

because the code is available or visible

to the users

next is server-side scripting is used as

a back-end but light side is used as a

friend thing now the next is server-side

scripting examples are like PHP JSP ASP

Python Ruby donate food etc and the

examples of client-side respecting of

JavaScript and VB script now

applications of server-side scripting

like customisation of website then

database

see the connection with the database

then dynamic pages creation etc and

client-side skeptics applications are

like users form-filling than anything in

the form filling so tight side aspectek

is basically used for reducing the cell

value so these are the basic differences

between server-side scripting and

client-side scripting thank you
