What is a Web Server?
Web servers are an important part of a website and it is important to understand how a web server works on the internet or the World wide web. A website doesn't just depend on the coding or content part it depends on how the website performs on the internet and how much it is efficient so we need a good web server.
A website is a collection of web pages while a web server is a software that responds to the request for web resources.
A web server is a computer where web content is stored and also the content is served on the internet. that's why a user visits your website and sees your all content over the world because of a web server.
Nowadays worldwide most famous & widely used web server is Apache 2 and other web servers are Nginx, Lighttpd, etc.
The biggest advantage of using this server supports all operating systems ( Windows, Mac, Linux, etc. ) and most websites ( around 70% ) are using Apache for hosting their content. Apache is open-source which means it is available for free, and can easily be accessed through online communities. a lot of online support is available in case you are stuck in a problem or error.
How does it be Works?
The web server responds to the client's request in two ways one is sending the file to the client associated with the requested URL ( Uniform Resource Locator ) and the second ways generating a response by invoking a script and communicating with the server.
URL is an acronym for Uniform Resource Locator and is a reference (an address) to a resource on the Internet
Example of URL: http://example.com
where the HTTP is the protocol identifier and the example.com is the resource address.
When you type a URL into a browser that means the client sends a request for a web page, the web server searches for the requested page if it exists or is found then it will send it to the client with an HTTP ( Hypertext Transfer Protocol ) response. and if the requested web page is not found or does not exist web server sends an HTTP response ( 404 not found )
What is HTML?
Basically, HTML is the main part of a web page. its full form is Hypertext Markup Language. and you can also imagine HTML is a bone of a web page because you use it to structure your web page.
The origin of the HTML language dates back to the physicist Tim Berners-Lee, its creator, a worker at CERN (European Organization for Nuclear Research) who at the end of 1989 proposed the HTML language together with the HTTP protocol, whose objective was to create a means to be able to share information between physicists of the time who worked all over the world.
The first version of HTML was released in 1991 ( HTML 1 ).
- HTML 2 - Released in 1995
- HTML 3 - Released in 1997
- HTML 4 - Released in 1999
- HTML 5 - Released in 2014
HTML 5 is the latest version and this version includes many outstanding features.
Basic structure of HTML:
<!DOCTYPE html>
<html>
<head>
<title>SM8UTI</title>
</head>
<body>
<h1>Smruti Ranjan Nayak</h1>
<p>SM8UTI</p>
</body>
</html>
in the above HTML code the <!DOCTYPE html> declaration defines that this document is an HTML document or file. the html, head, title, body these are called elements or tags. <html> is the root element. <head>, this element contains meta information, title, links, etc., and <body>, this element contains the body part of a web page or content part.
The two most used extensions of HTML documents are .html and .htm.
