Detailed explanation-1: -Explanation: As they require a large number of transistors, their cost per bit increases.
Detailed explanation-2: -Description: Register memory is the smallest and fastest memory in a computer. It is not a part of the main memory and is located in the CPU in the form of registers, which are the smallest data holding elements.
Detailed explanation-3: -The computer memory can be divided into 5 major hierarchies that are based on use as well as speed. A processor can easily move from any one level to some other on the basis of its requirements. These five hierarchies in a system’s memory are register, cache memory, main memory, magnetic disc, and magnetic tape.
Detailed explanation-4: -Explanation: The secondary memory is the slowest memory device. In the memory hierarchy, as the speed of operation increases the memory size also increases.
