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.

Best example for a WAN is the internet
a WLAN might fit your description better, but sure.

Nice explenation, but could you resize the images a bit because they're somewhat too big to follow properly.

During my travels on the net, I've read many extensive articles on Networks, whereby a lot of It was somewhat not necessary and Incorrectly documented.

This Is very simple and straight to the point. It'll certainly be of benefit to those who read It.
Nice contribution Indeed.

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.

This more accurately describes a MAN - A WAN is a greater regional, national, or international network.

And whats the point of this? This information is like on the first page of any networking book, and is explained in a much clearer manner pretty much anywhere else.

And what's the point of this? This information is like on the first page of any networking book, and is explained in a much clearer manner pretty much anywhere else.

The point of this thread is to provide a basic explanation of network types to users who may not understand it as well as your average techie. Granted, you can probably find better explanations somewhere else, but I do what I can.
