Identifying Network Topologies / Internet and Networking

Identifying Network Topologies :-

• Topology is the physical layout of computers,  cables,  and other components on a network  
•  Many networks are a combination of these topologies: 

       0. Bus
       0. Star
       0. Mesh
       0. Ring
       0. Wireless

• A bus topology uses a main trunk to connect multiple computers.  It there is a break in a cable,  it will bring the entire network down. 
• In a star topology,  all computers are connected through one central hub or switch.  If there is a break in a cable,  only the host that is connected to that cable is affected. 
• With a mesh topology,  every workstation has a connection to every other component of the network.  This type of topology is seen more commonly in something like the national telephone network. 
• In a ring topology,  all computers are connected in a ring with no begi6or end.  Each system in the ring regenerates the signal.  If there is a break in the ring,  the entire network goes down. 
• In a wireless topology,  radio frequenci6are used instead of physical cables.  Wireless clients connect to cells,  or access points,  through 5he ise of a wire-less network card. 
• A backbone is the main cable segment in the network.
