Star Topology
百度 面对巨额的优惠,客户的情绪也随即有所波动,而这时骗子则会提出先交定金,明天再去4S店办理手续等要求。A star topology is designed with each node (like workstations, printers, laptops, servers etc.) connected directly to a central device called as a network switch. Each workstation has a cable that goes from its network interface card (NIC) to a network switch.
Most popular and most widely used LAN technology Ethernet operates in Star or Star-Bus topology.

Advantages of Star Topology
? Easy to install and wire.
? No disruptions to the network when connecting or removing devices.
? Easy to detect faults and to remove parts.
Disadvantages of Star Topology
? Requires more cable length than a linear bus topology.
? If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in computer network communication.
? More expensive than linear bus topology because of the cost of the connecting devices (network switches).
