- Explain Amdahl’s Law of computer design.
Answer:
Amdahl’s Law:
In computer architecture, Amdahl’s law (or Amdahl’s argument) is a formula which gives the theoretical speedup in latency of the execution of a task at fixed workload that can be expected of a system whose resources are improved.
In computer architecture, Amdahl’s law is a formula which It is named after computer
