Which of the following describes best how AVX/AVX2 differs from SSE? AVX is primarly designed to add additional instructions that perform different calculations to the instructions in SSE O AVX is focussed on 256-bit SIMD vectors, whereas SSE is focussed on 128-bit SIMD vectors It's just a different set of marketing terms for different generations of the same thing. O AVX is a library that supports functions that require multiple SSE operations to calculate their results

How many hexadecimal digits are used when representing a nibble in hex form? 0 1 O 3 O 2 O O Patti the Programmer decides to create a function with three int16 parameters, sending all three by-reference. Will she need to pad her functions activation record to make it 32-bit aligned? O The answer will depend on how many registers get preserved on the stack O Yes O No O The answer will depend on the value of the passed parameters How many bits of stack memory are used when passing an int16 variable by-value to a function? O 32 O 64 O 16 O 8

Help me with these computer architecture questions, please. I need help with questions 3 and 4.

Can you explain please
