Question#1

Memory Architecture:

Memory architecture basically describes the methods that are used to implement electronic computer data storage in a routine that is basically a combination of the fastest and most reliable and it is the least expensive way that is been used to store and retrieve information

Question#2

The dynamic memory that is been allocated for any program is called the heap, The heap is basically the part of the  data structures where the new data allocation is been done in the unallocated region.

Question#3

Stack is been a static memory allocation that is been part of the memory unit. In stack when we allocate the variables then on the stack the variables that are been stored directly to the memory and access to this memory is very fast. Stack is been the process of LIFO that is been said as last in first out.

Question#4

Heap is basically the most important pillar of data structure. In DSA heap provides the dynamically allocated memory storage heap provides an exists until free scope.
