UNDERSTANDING LAN and its components
LAN can be defined as a network or networks of systems
limited computer located in one building, one kompleksgedung
or a campus and not using common media of communication facilities
such as telephone, but the owner and manager of media communications
is the owner of the LAN itself.
From the above definition we can know that a LAN is limited by
physical location. The use of the LAN itself mengakibatkansemua
computers connected in a network can exchange data or with
In other words related. This cooperation is increasingly grown from just
exchange of data through the use of equipment together.
LAN which generally use a hub, the hub will follow the principle that
own. In this case is that the hub does not have pengetahuantentang
destination address so that delivery of broadcast data, and also because
hub has only one collision domain so that if one port
busy then the other ports have to wait.
