Let’s take a closer look at these components

 

WHAT ARE “SERVERS” & “CLIENTS” ON THE INTERNET?

1.Server- A server can be thought of as a computer that has some software enabled on it that allows it that allows it to receive requests for a particular information from a client and then sends that information.

For Example, a file server hosts files that you, the client, would want to download. An email server allows you, the client to send and receive emails.

When you enter an address into your web browser, your web browser acts as a client. When you send and receive emails from the email app on your phone, it acts as a client requesting information from the email server.

The internet is the infrastructure and building block of the world wide web.

2.Web browser- A web browser is typically how we access the world wide web. The browser (Firefox, Chrome, Internet Explorer etc.) speaks the same language HTTP used by the WWW. It uses an address know as a URL – Uniform resource locator to access the web. Here’s an example of a URL:
