Computer Networking

Lets learn something called COMPUTER NETWORKING.
It is a basic network of two computers connected by a cable  to allow the exchange of data & share resources (photos,files, etc)

LAN =) Local Area Network - usually for small geographical area )ex: home, school, office)
MAN =) Metropolitan Area Network - used in bigger area, consist of multiple LAN. 
WAN =) Wide Area Network- large area too, consists of two or more LAN connected together  using communications of technology internet is the largest WAN
PAN =) Personal Area Network- smaller compared to others  (ex; printer, mobile devices)

device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN network. Routers are located at gateways, the places where two or more networks connect.
