The Internet is a great source of Information, Entertainment, and learning. But this is not the point. These are just applications. We need to discuss some basic definitions to explain it.
- Who owns?
- How does it work?
- How to connect it?
After this video, we will discuss some basic networking definitions.
A network is a group of computers connected to share their resources.
It is the network on networks. Thousands of networks are connected. The basic aim is to share resources and information.
In 1969, Advanced research and project agency(ARPA) designed the internet. It was ARPANET. They connect 04 nodes within the United States. Initially, it is designed to share research work between universities. Now billions of devices are connected.
There is no owner. Multiple organization manages it within their geographical limits. ISP are the big player in this field. Multiple levels of ISP are contributing. ISP provide infrastructure to connect and manage it. Local ISP provides the connectivity to end users.
How does it work?
Networking devices (Routers, switches, and servers) connect multiple networks. These devices handle the flow of information from one point to another point. Data flow in the form of bits.. every node has multiple paths. Data can take multiple routes to reach the same destination
A protocol is a set of rules and regulation. Multiple networking devices used to connect networks. All devices are of the different level and made by different manufacturers. Protocol provide the standard language to establish communication between these devices.
Internet protocol IP
IP is a used to communicate on the internet. Every device must have a unique IP address to communicate over the network.
How to connect.
Local ISP provides the connectivity to end user. We can connect to ISP server by using wireless or wire connectivity.
