This document provides an overview of key web technologies including browsers, static and dynamic websites, servers, DNS, databases, HTML, CSS, and JavaScript. A browser is an application that translates web code into rendered templates like Firefox, Chrome, and Safari. A static website stores each webpage as an HTML file directly from the server, while a dynamic website allows content to be delivered and displayed dynamically according to user behavior from a server-side language. A web server stores website files and connects to the internet to deliver content through a domain name and HTTP. DNS translates domain names to IP addresses so browsers can load internet resources. HTML is used to create web sites, CSS is used for designing HTML pages, and JavaScript allows for dynamic and interactive

2. WHAT IS A BROWSER
• APPLICATION THAT TRANSLATES WEB CODE INTO
RENDERD TEMPLATES
• EXAMPLE:
• FIREFOX
• CHROME
• SAFARI
• OPERA

3. STATIC WEBSITE
• A static website is made up of webpages created using HTML,CSS
and Javascript (all examples of web development languages). Each
page on a static website is stored as a single HTML file, which is
delivered directly from the server to the webpage exactly as is. This
content essentially becomes a part of the design on your page, and
won’t change unless the original HTML file is edited at a code level.

4. DYNAMIC WEBSITE
• Built using server side language and technology, dynamic websites
allow for the content of each page to be delivered and displayed
dynamically, or on-the-fly, according to user behavior or from user-
generated content.

5. WHAT IS A SERVER
The term web server can refer to hardware or software, or both of them working
together.
On the hardware side, a web server is a computer that stores web server software and
a website's component files (for example, HTML documents, images, CSS stylesheets,
and JavaScript files). A web server connects to the Internet and supports physical
data interchange with other devices connected to the web.
On the software side, a web server includes several parts that control how web users
access hosted files. At a minimum, this is an HTTP server. An HTTP server is software
that understands URLs (web addresses) and HTTP (the protocol your browser uses to
view webpages). An HTTP server can be accessed through the domain names of the
websites it stores, and it delivers the content of these hosted websites to the end
user's device.

6. EXAMPLE OF SERVERS
• NGINX
• APACHE
• LIGHTTDP

7. HOW INTERNET WORKS

8. URL STRUCTURE

9. WHAT IS DNS
• The Domain Name System (DNS) is the phonebook of the Internet.
Humans access information online through domain names, like
nytimes.com or espn.com. Web browsers interact through Internet
Protocol (IP) addresses. DNS translates domain names to IP
ADDRESSES so browsers can load Internet resources.

10. WHAT IS DATABASE
• SYSTEM THAT STORES AND MAKE AVAILABLE OF DIGITAL
DATA

11. What happens when a URL is requested?
• Browser looks up IP address for the domain. Browser initiates TCP
connection with the server. Browser sends the HTTP request to
the server. Server processes request and sends back a
response.
• Statuscode : 200OK
• Statuscode : 404 PAGE NOT FOUND
• Statuscode : 500 SERVER ERROR

12. HYPERTEXT MARKUP LANGUAGE
• HTML STANDS FOR HYPERTEXT MARKUP LANGUAGE
• HTML IS USED TO CREATE WEB SITE
• IT IS ALSO KNOWN AS INTERNET OF LANGUAGE

13. CASCADING STYLESHEET
• CSSS STANDS FOR CASCADING STYLESHEET
• CSS IS USED FOR DESIGNING OF HTML
• EVERY WEB PAGE USES CSS TO LOOK BEAUTIFUL

14. JAVASCRIPT
JAVASCRIPT IS A SCRIPTING LANGUAGE USED FOR WEB
DEVELOPMENT
JAVASCRIPTIS THE MAIN PART WHERE THE REAL CODING
STARTS
Javascript allows developers to create a dynamic and interactive web page to
interact with visitors and execute complex actions
