The storage system of a computer generally refers to memory and external memory. The memory mainly stores the programs and data needed for the current work of the computer, including cache memory and main memory, while the external memory mainly includes magnetic memory, optical memory and semiconductor memory. There are three implementation methods. The storage media include hard disks, optical disks, tapes and removable storage.

The storage system of a computer generally refers to memory and external storage.
The storage system refers to a system in a computer consisting of various storage devices that store programs and data, control components, and devices (hardware) and algorithms (software) that manage information scheduling.
The storage system is one of the important components of the computer. The storage system provides the ability to write and read information (programs and data) required for computer work, and realizes the computer's information memory function. Modern computer systems often use a multi-level storage architecture of registers, cache, main memory, and external memory.
The core of the computer storage system is the memory. The memory is an essential memory device in the computer and is used to store programs and data.
Internal memory (referred to as memory) mainly stores the programs and data required for the current work of the computer, including cache memory (Cache, referred to as cache) and main memory. At present, memory is mainly composed of semiconductor memory. External memory (referred to as external memory) mainly has three implementation methods: magnetic memory, optical memory and semiconductor memory. The storage media include hard disks, optical disks, tapes and mobile memories.
The multi-level storage architecture of modern computer systems is as shown in the figure. The top is closer to the CPU, the faster the memory, the smaller the capacity, and the higher the price per bit. Adopting this organizational method can better solve the contradiction between storage capacity, speed and cost, providing a layer of memory that is logically equivalent to the cheapest in terms of price and capacity, and the access speed is close to the fastest in the storage system. Layer memory storage system.
