Dedicated links have a single transverse, thus needing to know only two points of reference for delivering packets. When thousands of networks are connected to each other, switching is used. What type(s) of switching is/are there?
A)Circuit Switching
B)Packet Switching
C)Both A and B
D)Neither A nor B

There are two types of switching: circuit and packet. Circuit switching sets up a virtual connection that acts like a dedicated link between two systems. When the source system makes a connection with the destination system, they set up a communication channel. If the two systems are local to each other, few devices need to be involved with setting up this channel. The farther the two systems are from each other, the more the devices are required to be involved with setting up the channel and connecting the two systems. Packet switching does not set up a dedicated virtual link and packets from one connection can pass through a number of different individual devices instead of all of them following one another through the same devices. The infrastructure that supports these methods is made up of routers and switches of different types. They provide multiple paths to the same destinations.
