Network
Networks allow the transfer of data between connected devices
LAN and WAN
HUB
SWITCH
Wireless Access Point
LAN stands for local area network. It is confined to one site so it is relativly small
WAN is set up on one site, the hardware is owned by the organisation and it covers large area's unlike LAN
Advantages of LAN
Digital communication between people is enabled
Allows sharing of digital information
Allows sharing of peripheral devices
Allows system to be updated with the latest software from a central point
Disadvantages of LAN
Expertise are required to install and maintain large networks
Security issues
You required at least two nodes
Each having a NIC These transfer signals to the netowork
A device that connects nodes together
Makes all the connected nodes act as a single segment
Cheap devices like a USB hub
A device that connects nodes together
An intelligent device that can create and connect to different segments of the network
Directs Network Traffic
Wireless no need to do building
Add a new node to the system with ease
There are performance issues and security issues too
