Bus Cable
A cold sore itself can cause swollen lymph nodes.
It is connected by a network cable, switch and a router.
These two structures are the lymph nodes and the spleen.
In a tree topology, a combination of cables can be used, but the most common type is coaxial cable or twisted-pair cable (such as CAT5e or CAT6). These cables facilitate the connection between the central nodes and the individual branches of the network. Fiber optic cables may also be used for high-speed connections between nodes in larger or more complex tree topologies. The choice of cable often depends on the specific network requirements and the distance between nodes.
Child Nodes
Swollen lymph nodes would be a symptom of a disease rather than the disease itself.
Cable is split into "nodes", which encompasses several residential units. Cable also has a limited amount of bandwidth. If the sum of all offered bandwidth for all subscribers on a node exceeds the amount of bandwidth actually available for the node, it is definitely possible to have periodic decreases in connection speed during peak usage.
A bus topology needs a trunk cable, which is a high speed central cable to which all the nodes can be connected. If the trunk cable breaks down, however, the whole network comes to a halt.
