Network Fundamentals

Network Fundamentals

Undertaking 1

1.What is Networking?
Networks are simply things connected. For example, your friendship rotary: you are all connected because of similar interests, hobbies, skills and sorts.
Networks can be found in all walks of life:

• A city's public transportation arrangement
• Infrastructure such as the national superpowe power system for electricity
• Meeting and greeting your neighbours
• Communication systems for sending letters and parcels

But more specifically, in computing, networking is the equal idea, just distributed to technological devices. Take your phone as an example; the reason that you cause it is to access things. We'll cover how these devices communicate with each new and the rules that succeed.

In computing, a n e twork can be formed by anywhere from 2 devices to billions. These devices let in everything from your laptop and speech sound to security cameras, traffic lights and even farming!

Networks are amalgamated into our everyday life. Be information technology gathering information for the weather, delivering electricity to homes or even determining WHO has the right of agency at a road. Because networks are so embedded in the contemporary, networking is an essential concept to grasp in cybersecurity.

Lease the diagram below as an representative, Alice, Bobber and Jim have formed their network! We'll come onto this a bit afterwards.

2.What is the Internet?

3.Identifying Devices on a Network

Devices on a net are very similar to humans in the fact that we have two ways of organism known:

• Our Name
• Our Fingerprints

Now we can change our name through and through deed poll, but we can't, even so, change our fingerprints. Every hominal has an individual set of fingerprints which way that even if they vary their name, thither is even so an identity element behind it. Devices have the same thing: two substance of identification, with combined being permeable. These are:

• An IP Address
