So here’s an example of my Home Network once again

I’m connected to my BT Router when I click on change Adapter Settings

in Windows I can see various adapters and I'm going to double click

on my Local Area Connection Adapter this is the physical interface

that I am using to connect to the network

I can see the speed that I am connected to the network with,

we’ll talk more about speed later. I can click on details and I can see

the physical network card that I am using to connect to my network

I can see other information including IP Address

and a Physical Address or MAC Address.

We’ll talk more about this later but what I’d like to point out

is that I have a logical IP Address configured on my PC

and I am using this protocol or language Internet Protocol version 4

for communicating on my local network as well as unto the Internet.

Now in summary some Home or SOHO in other words Small Office Home Office

networks can get fairly complicated but in its most basic form a network

is simply 2 devices connected via cable or via a wireless network

sharing resources or information with each other.

So think of it as follows the PC has a photograph that we want

to copy to the laptop to do that we can cable the 2 devices together

and simply copy the file across. These days however we tend to use

wireless networks more and more for sharing of data and information

especially with the growth of iPads, iPhones and other mobile devices.
