About the Internet:

The Internet is a global wide area network that connects computer systems across the world. It includes several high- Bandwidth data lines that comprise the internet “Backbone”. These lines are connected to major internet hubs that distribute data to other locations, such as web servers and ISPs.

In order to connect to the internet, you must have access to an internet service producer(ISP), which acts as the middleman between you and the internet. Most ISPs offer broadband Internet access via Cable, DSL, or fiber connection. When you connect to the internet using a public Wi-Fi signal, the Wi-Fi router is still connected to an ISP that provides Internet access. Even cellular data towers must connect to an Internet Service provider to provide a connected device with access to the internet.

Note:

Wide Area Network: It is similar to a Local Area Network(LAN), but it’s a lot bigger. Unlike LAN’s WANs are not limited to a single location. Many wide area networks span long distances via telephone lines, fiber optic cables, or satellite links. They can also be composed of smaller LANs that are interconnected. The Internet could be described as the biggest WAN in the world.

Bandwidth: Bandwidth describes the maximum data transfer rate of a network or internet connection. It measures how much data can be sent over a specific connection in a given amount of time.

Network hub: A network hub is a device that allows multiple computers to communicate with each other over a network. It has several Ethernet ports that are used to connect two or more network devices together. Each computer or device connected to the hub can communicate with any other device connected to one of the hub’s Ethernet ports.

Ethernet: It is the standard way to connect computers on a network over a wired connection. It provides a simple interface and for connecting multiple devices, such as computers, routers, and switches. With a single router and a few Ethernet cables, you can create a LAN, which allows all connected devices to communicate with each other.
