1. Local Area Network (LAN)
LAN is a network used to connect one computer to another computer with a narrow area, such as network office buildings, campuses and others. Through this network a single computer with other computers that can exchange data (sharing), and allows for the sharing of hardware devices. Menia is used to enable mutual terhubungnya one computer with another computer
a.Kabel UTP
UTP (Unshielded Twisted Pair) is a cable menia data transaction in which there are 4 pairs of wires threaded (twistwed Pair Wire), so that the wires are all there are 8 wires. Each pair of these akawat given color code, the first full color (Blue, Orange, Green or brown) and her partner who had been threaded around the main strip in white and colors that fit with their partner. There are two types of UTP cable that is Shielded Twisted Pair (STP), a cable with a sheath wrapping and Unshielded Twisted Pair (UTP) cable without sheath wrapping.
b.RJ-45
RJ45 is a connector mounted on each end of the cable UTP / STP, RJ-45 connectors on this miripdengan telephone cable (RJ-11). When the telephone wires using three pairs of wires, the cable network is four pairs.
c.Repeater
Repeater function to help strengthen the signal is weakened by distance, so the signal can be transmitted to the longer distances.
d.Hub
Hubs connect all computers connected to the LAN. Hub is a repeater with a lot number of ports (multiport repeater). Hubs are not able to set goals; Hub only transmit signals to each line is connected with it, using half-duplex method.
e.Bridge
Bridge is the intelligent repeater which amplifies the signal that ditransmisikannya, but not as a repeater, Brigde able to determine the destination. Easily, Bridge set (through filtering or forwarding) data frames per segment.
f.Switch
Switches connect all computers connected to the LAN, same as the hub. The difference is that switches can operate with full-duplex mode and is able to divert the path and filter the information to and from specific destinations. Easily, Combining multiple computers into one network /*Data terkait*/
