Is node a computer system

Answer 1

Other meanings and examples for the word node:

1. A group or collection of cables or wiring that connects to a larger system. For example, cable TV signals are sent from the head end of a cable company through to a local center that houses nodes, before wiring carries it to customers.
2. A particular spot where electrical impulses come together in a muscle and are sent out from that location, for example, the AV node in the human heart. When the heart muscle develops an irregular rhythm, selective destruction of the AV node through heat, freezing, or electrical jolt can stop the abnormal firing of electrical impulses across the heart and put the heart back into a normal rhythm, aided by a pacemaker.
