URL
a Uniform Resource Locator or Universal Resource Locator (URL) is a character
string that specifies where a known resource is available on the Internet and the
mechanism for retrieving it. Every URL consists of some of the following: the scheme
name (commonly called protocol), followed by a colon, two slashes, then depending on
scheme, a domain name (alternatively, IP address), a port number, the path of the
resource to be fetched or the program to be run, then, for programs such as Common
Gateway Interface (CGI) scripts and a query string
DOMAIN NAME SYSTEM
The Domain Name System (DNS) is a hierarchical distributed naming system for
computers, services, or any resource connected to the Internet or a private network. It
associates various information with domain names assigned to each of the participating
entities. Most importantly, it translates domain names meaningful to humans into the
numerical identifiers associated with networking equipment for the purpose of locating
and addressing these devices worldwide. An often-used analogy to explain the Domain
Name System is that it serves as the phone book for the Internet by translating humanfriendly
computer hostnames into IP addresses.
COMMON WEB PROTOCOL
A.) HTTP (HyperText Transfer Protocol ): It is a standard over the internet for
transferring data. Browser is an HTTP Client which sends request to the HTTP server
which gives response back to the client. HTTP is an stateless protocol which makes it
more efficient to work.
HTML AND CSS
HTML: Hypertext Markup Language (HTML) is the markup language for web pages.
HTML elements are the basic building-blocks of WebPages. HTML is written in the form
of HTML elements consisting of tags, enclosed in angle brackets (like <html>), within
the web page content. HTML tags normally come in pairs like <h1> and </h1>. The first
tag in a pair is the start tag, the second tag is the end tag (they are also called opening
tags and closing tags). In between these tags web designers can add text, tables, images,
etc.
