What is a Browser?
A browser is a software program that is used to explore, retrieve, and display the information
available on the World Wide Web. This information may be in the form of pictures, web pages,
videos, and other files that all are connected via hyperlinks and categorized with the help of URLs
(Uniform Resource Identifiers). For example, you are viewing this page by using a browser.
A browser is a client program as it runs on a user computer or mobile device and contacts the
webserver for the information requested by the user. The web server sends the data back to the
browser that displays the results on internet supported devices. On behalf of the users, the browser
sends requests to web servers all over the internet by using HTTP (Hypertext Transfer Protocol). A
browser requires a smartphone, computer, or tablet and internet to work.

What is the URL (Uniform Resource Locator)?
A uniform resource locator is the address of a resource on the internet or the World Wide Web. It is
also known as a web address or uniform resource identifier (URI). For example, https:
www.javatpoint.com, which is the URL or web address for the javatpoint website. A URL represents
the address of a resource, including the protocol used to access it.
A URL includes the following information:
It uses the protocol to access the resource.
It defines the location of a server by IP address or the domain name.
It includes a fragment identifier, which is optional.
It contains the location of the resource in the directory of the server.
A URL forwards user to a particular online resource, such as a video, webpage, or other resources. For
example, when you search information on Google, the search results display the URL of the relevant
resources in response to your search query. The title which appears in the search results is a hyperlink
of the URL of the webpage. It is a Uniform Resource Identifier, which refers to all kinds of names
and addresses of the resources on the webservers. URL's first part is known as a protocol identifier,
and it specifies the protocol to use, and the second part, which is known as a resource name,
