Xampp tutorial

 XAMPP:

1.) A web server : When you search for something on Facebook or any website, the data is fetched from a web server where it's stored. So, yes, the place where they store data is often called a web server. Great job on connecting the dots.

First user request to HTTP server than http server request to file system if the data which user want is in file system it gives to http and hence http send it to user's browser in form of html

HTTPS uses encryption to protect the data you send and receive on the internet, making it a more secure way to communicate and do things like online shopping or banking while http don't

2i i.)so many webpages == website

1iii.)web server is a program

1iv.)web servers already have web page

1v.) web server have an ip adress

1vi.) how does it works(image 'webserver works') they all know each other by IP  

1v.) if the data is not in webserver they show '404 page not found' error

1vi.)if a device is always connected to internet and server software installed, than it can become server software install.

1vii.)A user have a device from which we send a request using a web browser to internet then to web server(which only have authority to manage request and responce/ http) and then to file system 

web client --> Request --> Internet --> request --> Web servers --> request --> file system

1viii.)Apache web server, 60% used, open sourec and free

1ix.)internet information Server(IIS), by microsoft, no open source, for some os like windows

1x.) Nginx Service Server, Open source server: 

Your Device: This is where you are – your computer or phone.

Proxy Server: This is the middleman. It takes your requests and sends them on your behalf.

Internet: The final destination, where the proxy sends your requests (like opening a website).

IMAP (Internet Message Access Protocol) and POP3 (Post Office Protocol 3) are email protocols. They allow you to retrieve emails from a mail server to your device. IMAP keeps emails on the server, allowing you to organize and sync them across multiple devices. POP3, on the other hand, downloads emails to your device, removing them from the server.

Nginx is a web server that serves web pages to users. It's known for its speed and efficiency. It can also act as a reverse proxy and load balancer.

1xi.) Some more web servers:

jigsaw web server: open source and free

Sun java web server: free but not open server

1xii.)features of web server: 

HTTP Protocol and Web Server: A web server uses the HTTP protocol to communicate with browsers. It's like the agreed language for them to exchange information.

Login and Web Server: When you log in to a website, the web server checks your credentials to ensure you're allowed access.

Authentication and Web Server: The web server authenticates (checks) your identity during the login process. It's like the bouncer at the entrance verifying your ID.

Handling and Web Server: The web server handles requests from users, managing tasks like fetching files or processing data.

Security and Web Server: Web servers implement security measures to protect data and ensure safe communication between users and the server.

Virtual Hosting and Web Server: A web server can host multiple websites on the same machine through virtual hosting, treating each like it has its own server.

Bandwidth Throttling and Web Server: Web servers may use bandwidth throttling( This is done to control the amount of data that can be transmitted over a network, and it's often used to manage network congestion and ensure fair usage among users.) to control data transfer speeds, ensuring fair usage and optimal performance for all users.

1xiii.)HTTP = hyper text transfer protocol

1xiv.)TCP sends the data but don't know where to send data so IP tell where to send the data

1xiv.)Application Server is so much better than web server

2.) BACKEND(JAVASCRIPT)

3.)A web server is a software application or a hardware device that serves web pages to users over the internet.

4.) Xampp is the perfect tool to setup a web server locally.

5.) It uses apache.

6.) if there is an errot it can be because skype

7.) we can see used ports in 'resource monitor > network' in windows
