Definition: Untapered, also known as a "tapered" or "unrolled" object in computer science, refers to an object whose dimensions are not defined at compile time but can be determined during runtime. This property allows for more efficient use of memory and reduces the size of the program by eliminating unnecessary data structures. In programming, it is common to have objects that are stored as a series of bytes or other unit-sized data structures in memory. These objects are not typically defined at compile time
