============================================

Client:
=======

IBPS ==> Project of Banking sector ==> TCS

an end user device

a software which we can use to request for anything to the server.

====================
SERVER
======

gmail:
	mail id
	pwd
		login
home page ==> response
invalid credentials

server is a software which it can accept the request from the client and processing that request finally provide the response.

client =========> server 
	http request
	<========
	http response

http: ==> hyper text transfer protocol

===========================

BROWSER
=======
is the client software
	which we can to request the server.

we can use to access any kind of the web application

Types of browsers:
	Chrome, Firefox, Edge, Internet Explorer, Safari, Opera, Mozilo etc.

==================================

To develop the web application, the technologies are:
	1) HTML
	=======
		Hyper Text Markup Language
			using tags the development is achieved ==> Markup Languages.
		==> The text which can use to navigate from one place to another place called as "Hyper Text".
		Tag based 
		Syntax:
			<name>
		<html>
		Tags are of two types:
			1) Paired Tags
				<open> and <close>
			Syntax: HTML Element
				<tag> content </tag>
			the HTML element is the combination of open tag, close tag and the content.
		the name of the tag is: the text in between angular braces
		ex: <h1> </h1>
		<xyz> content </xyz> ==> xyz element

			2) Unpaired Tags 
			================
				Self closing tags
				the tags with only open tags (not required the closing tags)
			ex: <img>, <br>, <hr>, <input> etc.
==> developed by Time Berners lee, 1991
HTML Versions:
	HTML 1.0 ==> 1991
	HTML 2.0 ==> 1994
	HTML 3.0 ==> 1997
	HTML 4.0 ==> 1997
	HTML 5.0 ==> 2014
	HTML 5.1 ==> 2016
	HTML 5.2 ==> 2017
	HTML 5.3 ==> 2018

features of HTML:
================
1) Tag based language
2) Case Insensitive language
	<h1> or <H1>
<h1> </H1>
3) Define basic HTML page

Limitation:
==========
	we cannot define the styles to webpage.

	2) CSS
	======
		Cascading Style Sheet
		==> Property based language
			use to define different styles to HTML page
			like: color, bgcolor, margin, padding, borders, flex etc.
		==> for every property there is a value.
		ex: font-family : verdana, color : rgb(122,200,123), color name
		current version: css3

Note: with proper combination of HTML and CSS, we can develop good looking and meaningful website.

Limitation:
===========
	we cannot achieve functionality

	3) JavaScript
	=============
		JS
		Statement based
			ex: int a = 10;
			var a = 10;
			let b = 20;
			const c = 25;
		Server based programming language
		client based 
		to define the functionality for human interactions with application
		derived from ES (ECMAScript), developed by w3c
		World wide Web Consortium
