I recently just bought my first PC and i want to stay safe on the internet. Could you help explain to me how it works?

Sure dude

First off, you should know what a computer network is. A computer network is a set of computers connected together for the purpose of sharing resources.

Even mine will be if i access the internet right?

That's correct.

A packet is pieces of messages transmitted over networks known as diagrams

Is there a chance that there may be different kind of networks?

There indeed are multiple kinds of networks. LAN and WAN. To put it shortly, LAN is for a relatively small area while WAN is for a large area.

That would be a Node. Every Node has their own MAC which is the physical address of any device. An IP address is the online address used to help identify each computer on a network

What do you call something that is connected to the network?

Going back on the topic of Nodes, is there a specific way the nodes are connected? And if there is whats the difference?

There are many types of connections

Here are some types of connections

Bus

Ring

Token Ring

Star

Tree

This is a bus topology. Every Node here is connected to a single line, when that line fails, the whole topology dies. But when one node fails the whole system will continue working.

This is a Ring topology. Everything is connected in a circle. I personally hate this kind of topology because if one node dies, all the nodes after it dies.

This ones a bit more complex. It basically forms a ring again, but this time, you have a hosts sending information to Nodes.

Star topology is a topology completely relying on one host node sending information to every other node. It's fairly reliant unless the main node dies.

Last one I'll be talking about is tree topology. All it is basically is a combination of star and bus topology

Jeez, there sure are many different types of Topologies. What else do I need to know about the internet before accessing it?

Ohh boy, were gonna be here for a while. I'll just state some of the more useful terms you may need to know.

Afterwards I'll teach you about some of the physical hardware used to connect to the internet.

A Protocal is an agreed-upon format to transmitting data between two devices.

P2P is a type of network in which each workstation has equivalent capabilities and responsibilities. This may be a term that you wouldnt really use in your day to day life.
