Let's get started

The internet is not owned by any individual or group. The internet is a worldwide collection of interconnected networks, cooperating to exchange information using common standards.
Internet users can exchange information through the following medium:
Wireless transmission
Wires and fibre -optic cables

Everything that you access online is located somewhere on the global internet. for example, Multiplayer games, online courses, and social media sites
- Local Networks
Local networks can range from simple networks consisting of two computers to networks connecting hundreds of thousands of devices.
Large networks, mainly used in business, can be used to advertise and sell products, order supplies, and communicate with customers. Small networks, mainly used in small offices or homes, can let you share resources such as Printers, documents, Pictures and music.
The internet is considered a "Network of networks" because it is made of thousands of local networks that are connected.
Example of different networks are:
I.Small home networks
Small home networks connect a few computers to the internet.
II.Small Office and Home Office network(SOHO)
The SOHO network allows computers in a home office to connect to shared resources.
III.Medium to Large networks
These are networks used by schools and corporations, and they can have many locations with hundreds or thousands of interconnected hosts.
