Answer:
Computer data storage is a technology consisting of the computer components and recording media that are also used to retain digital data. It is a core function and the fundamental component of computers.
The central processing unit (CPU) of the computer is what manipulates data by performing computations. In the practice, almost all computers use a storage hierarchy, which puts fast but also expensive and small storage options close to the CPU and slower but then less expensive and larger options further away. Generally fast volatile technologies (which lose data when off power) are referred to "memory", while slower persistent technologies are referred to "storage".
Even the first computer designs, Charles Babbage's Analytical Engine and the Percy Ludgate's Analytical Machine, clearly distinguished between processing and the memory (Babbage stored numbers as rotations of gears, while Ludgate stored numbers as the displacements of rods in shuttles). This distinction was extended in Von Neumann architecture, where the CPU consists of the two main parts: The control unit and arithmetic logic unit (ALU). The former controls the flow of data between CPU and memory, while latter performs arithmetic and logical operations on data.
