The register that stores the result of the latest computation carried out by the CPU is called the Accumulator. This is a specialized register within the CPU architecture specifically designed to hold intermediate results of arithmetic and logic operations. As computations are performed, values are often loaded into the Accumulator, allowing for efficient processing and quick access to results that will be used in subsequent calculations.

The Accumulator plays a vital role in the execution of instructions, especially in simple CPU designs and scalar processing architectures, where it may serve as the main temporary storage for data being processed. Other registers, such as the Index Register, Stack Pointer, and Data Register, serve different specific purposes within the CPU, like addressing memory locations or managing data on the stack, but they do not function primarily as the result-holder for computational operations like the Accumulator does.
