Kegiatan PIMNAS 2014TOPOLOGIES

There are three main local area network (LAN) topologies:

Bus

Star

Ring

Other network topologies include:

Mesh

Wireless

4BUS TOPOLOGY

The bus topology supports thick and thin coaxial segments.

Segments are connected by repeaters.

The bus topology uses the baseband signaling method.

Signals are broadcast in both directions simultaneously.

Both ends of each segment require termination to avoid reflection.

End systems connect to the segment in a linear manner.

STAR TOPOLOGY

The star topology can use coaxial, twisted pair, or fiber optic cable.

A central device (hub) connects hubs and nodes to the network.

Each node connects to its own dedicated port on the hub.

Hubs broadcast transmitted signals to all connected devices.

You can connect multiple hubs to form a hierarchical star topology.

The star topology uses the baseband signaling method.15

RING TOPOLOGY

The ring topology can use twisted pair or fiber optic cabling.

A central device (hub) connects hubs and nodes to the network.

Each node connects to its own dedicated port on the hub.

You can connect multiple hubs to form a larger ring.

The ring topology uses the baseband signaling method.

Frames are transmitted around the ring from node to hub to node.

Media Access Control (MAC) is used for token passing. 18

Wiring within a twisted pair cable is configured as either

1) Straight through, where each wire (or pin) is attached to the same contact point at each end

2) Crossover, where transmit contacts on each end of the cable are connected to the receive contact at the other end

SUMMARY

The three basic LAN topologies are bus, star, and ring. WLANs are becoming more popular. Mesh networks are not typically used in LANs.

The primary cable types used in LANs are coaxial, twisted pair, and fiber optic.
