(a) Moore's law
(b) Djikstra's algorithm
(c) Amdahl's law
(d) Murphy's law

Answer 1

Moore’s law:

Number of transistors per square inch on integrated circuits doubles every year

 Murphy's law:

Anything that can go wrong, will go wrong

Amdahl law:

Finds the maximum improvement possible by improving a particular part of a system.

If P part of N processor system is made parallel, speed up=1/((1-P)+(P/N)
