Web Page
A Web page is a single document within a website. It may include text, images, videos, links, and
other multimedia content. Web pages are created using Hypertext Markup Language (HTML)
and are viewed through a Web browser. When you explore a website, you are looking at one or
more Web pages that are connected to each other.

A website is a collection of Web pages that are interlinked with each other. A website may
contain thousands of Web pages.

or communication channel. It is typically measured in bits per second (bps), kilobits per second
(Kbps), megabits per second (Mbps), or gigabits per second (Gbps). There are different kinds of
bandwidth, such as network bandwidth, data bandwidth, and digital bandwidth.
