It is a fundamental building block of the central processing unit (CPU) found in many computers. This is in contrast to a floating-point unit (FPU), which is a digital circuit that operates on floating point numbers with the aid of one or more internal ALUs. Powerful and complex ALUs are often used in modern, high performance CPUs, FPUs and graphics processing units(GPUs). A single CPU, FPU or GPU may contain multiple ALUs.

4. can you explain abaut ROM, RAM? with your own words
