In the usa virgin mobile uses the sprint pcs network and everywhere else it uses the tmobile network
yes, network topology does matter to design a network. as we know that topology is a structure of network. without a topology network cannot be designed. we have to consider which topology to use and what does each topology does. different topology have its different features. if you want most secure connection use full mesh topology
Bus Topology
1star topology
ring/hybrid
Bus Network Topology.
Mesh Topology... though if you use a beefy-enough machine in the middle, a Star topology might work.
Star
Hybrid
Wireless.
Star Topology
SONET use RING physical topology and TOKEN logical topology. As simple as that. Logical topology deals with the data transmission. Physical topology deals with how the network is connected physically , BUS, RING, STAR and the like.
Star topology:- In this topology all PC are connected with the central device. Central may be HUB and SWITCH. Star widely use in all over word. Ring topology:- In this ring topology all PC are connected in the frame of ring are close Ring topology use MSAU each PC has a two never road one is called up Stream and called down stream. It used token passing Matterhorn which implement the token ring network. " Is the best of star topology".
