Computer networks, in their most basic definition, are relays of information, data, and instructions passed from one computer to another.
There are a few types of networks. From smallest to largest: localhosts, LAN, WLAN, WAN and the internet.
Localhost:
Localhost isn't really considered a network, but it's your computer's internal network, accessible without any connected networking devices (like Ethernet or Wifi)
LAN:
LAN stands for Local Area Network. LAN connections are commonly used in small office buildings or schools.
A LAN network is established by connecting multiple computers using RJ45(Ethernet) cables to share information and resources.
An example of LAN would be my school's network system. On our desktops, there's a shortcut to the school's shared drive. From there, you can access pickup and dropoff folders for assignments and handouts.

WLAN:
WLAN stands for Wireless Local Area Network. It's essentially a LAN network, minus the cables.
An example, again, would be my school's system. I know I mentioned this previously, but that was for school computers. In a TDSB (school board) school, logging into the wifi grants you access to the same things you can reach from the desktops.
WAN:
A WAN network is a Wide Area Network that connects two or more LAN networks together. This is commonly used in multi-building corporations and school boards. An example, for a third time, is the TDSB.
From any computer connected to the TDSB WAN, I can access my student H:/ Drive. The H:/ Drive isn't stored on the computer, but rather in Etobicoke, at TDSB headquarters.

It's often the outcasts, the iconoclasts ... those who have the least to lose because they
don't have much in the first place, who feel the new currents and ride them the farthest.
