Copies of birth certificates and other personal vital records can only be obtained from the state or US possession where the documents were originally filed. Most states provide a centralized source from which birth certificates and other vital records can be ordered.opies of birth certificates and other personal vital records can only be obtained from the state or US possession where the documents were originally filed.

Tree Topology: This is a hybrid topology that combines characteristics of linear bus and star topologies. In a tree network, groups of star-configured networks are connected to a linear bus backbone cable.
In Bus Network Topology a single cable is used to connect all devices on the net. This cable is often referred to as the network Backbone. When communication occurs between nodes the device sending the message broadcasts to all nodes on the network, but only the desired recipient digests the message.ince Logical Network Topology builds upon the underlying Network Physical Topology the set of standard computer physical topologies will reviewed first as background to the performance analysis discussion. This will be followed by a brief description of Graph Theory, and then the network analysis examples.
