How Race Around Condition can be avoided?
Ans:
The race around condition can be avoided if
1. Duration of clock pulse being high is small like comparative to the delay of the gates.
It is difficult due to very small propagation delay in IC's.
2. A master slave JK flip-flop is utilized. In such 2 SR flip-flops there is feedback from the second output to the input of the first flip-flop. + CLK or positive clock pulses are applied to the first clock pulse and clock pulse are inverted at the second flip-flop while second is disabled clk'=0 and clk=1 first flip-flop is enabled.
At time t when an infected machine scans and finds a vulnerable machine, the vulnerable one will be compromised and start to scan and infect others at time t+X, where X is a r.v. f
