connectivity among networked devices.

via the Internet or an intranet.
Client
A client is a computer that relies on a server to provide specific resources. For instance, if a server
hosts a network version of Microsoft Excel, all client computers on the network can access and
use that version of Excel through the server.
Internet
The Internet is a global network connecting millions of computers and networks around the
world. It enables users to access and exchange information across the network. With billions of
websites, the Internet offers a vast array of information and services.
Intranet
A private network within an organisation that uses Internet technology to securely share company
information and resources among employees. An intranet restricts access to authorised users
within the organisation, unlike the Internet, which is a global network accessible to the public.
URL
URL stands for Uniform Resource Locator. It is the address used to find a specific Web page or
resource on the Internet. It tells your Web browser where to look for information. For example,
www.google.com, www.rediffmail.com.
ISP
ISP stands for Internet Service Provider. It is a company that offers Internet access to customers,
usually for a monthly fee. Some examples of ISPs are Airtel, Vodafone Idea (VI), BSNL (Bharat
Sanchar Nigam Limited), MTNL (Mahanagar Telephone Nigam Limited), and Jio.
IP Address
An Internet Protocol (IP) functions as a directory for the Internet. It translates user-friendly
website names (like www.google.com) into numerical IP addresses that computers use to locate
and connect to the website. This system simplifies Web navigation, allowing users to visit websites
using easy-to-remember names instead of complex numerical addresses.
DNS
Domain Name System (DNS) is a naming system for assigning a name to the computers,
services, or other resources connected to the network. This name is known as a domain name.
For example, the domain name in the www.yahoo.co.in URL is yahoo.co.in. This domain name is
internally converted into an IP address.
