These cards are issued by a state or country in which medical cannabis is recognized. Typically a patient is required to pay a fee to the state in order to obtain a medical marijuana card. In most states with medical marijuana card programs, the card is valid for up to 12 months and may be renewed.
Alternatively referred to as a ring network, ring topology is a computer network configuration where the devices are connected to each other in a circular shape. Each packet is sent around the ring until it reaches its final destination.
In Ring Topology, all the nodes are connected to each-other in such a way that they make a closed loop. Each workstation is connected to two other components on either side, and it communicates with these two adjacent neighbors. Data travels around the network, in one direction.
