WebMultistage interconnection networks (MINs) are a class of high-speed computer networks usually composed of processing elements (PEs) on one end of the network and memory elements (MEs) on the other end, connected by switching elements (SEs). The switching elements themselves are usually connected to each other in stages, hence the name. … WebCAN-Bus Hardware. The bus line is a twisted pair wire with a termination resistor (120 Ohm) on each side. One wire is called CAN High and one wire is called CAN Low. Both wires are needed for proper communication. A device which is connected to the bus is called a ‘Node’. There are always two or more nodes required on the CAN network to ...
