In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a computer system. [1] [2] Heartbeat mechanism is one of the common techniques in mission critical systems for providing high availability and fault tolerance of network services by detecting the network or systems failures of nodes or daemons ...
A delta ray is a secondary electron with enough energy to escape a significant distance away from the primary radiation beam and produce further ionization. [1]: 25 The term is sometimes used to describe any recoil particle caused by secondary ionization.
