The relationship between the amount of memory and hard disk space

Never mind. Memory is used to temporarily store files while the operating system is running software.

The hard drive is where the files really go.

What is memory?

There is a very important part of the structure of a computer, which is memory. Memory is a part used to store programs and data, for a computer, with memory, there is a memory function, in order to ensure normal operation. There are many types of memory, which can be divided into main memory and auxiliary memory according to their use, the main memory is also known as internal memory (referred to as memory), and the auxiliary memory is also known as external memory (referred to as external memory).

External memory is usually magnetic media or optical discs, such as hard disks, floppy disks, tapes, CDs, etc., which can store information for a long time and does not rely on electricity to store information, but it is driven by mechanical parts, and the speed is much slower than that of CPU. Memory refers to the storage component on the motherboard, which is the part that the CPU directly communicates with and uses to store data, and stores the data and programs that are currently in use (that is, in execution), its physical essence is a group or more groups of integrated circuits with data input and output and data storage functions, and the memory is only used to temporarily store programs and data, once the power is turned off or the power is off, the programs and data will be lost.

What is a hard disk A hard disk is one of the most common types of external storage, which is like an external repository for data. In addition to having a "workshop", the computer also needs to have a warehouse for storing things. A hard disk, also known as a fixed disk, is composed of a platter coated with a magnetic material and a platter reading and writing device.

These platters are sealed together with the read-write device (drive). The dimensions of hard drives are inches, inches, and inches, among others. There is a type of hard disk that can also be connected through a parallel port as a convenient mobile hard disk.

Independent of each other, there is no relationship.

No contact, hard disk is a cup, memory is a cup with holes.

The difference between hard disk capacity and memory capacity is as follows:

First, the reference is different.

1. Hard disk capacity: In megabytes (MB) or gigabytes (GB), the mainstream hard disk capacity is 500G 2TB, and the factors affecting the capacity of hard disk are single disk capacity and the number of disks.

2. Memory capacity: refers to the capacity of random access memory (RAM), which is the key parameter of the memory module.

Second, the measurement standards are different.

1. Hard disk capacity: Capacity is the most important parameter of hard disk. Disk capacity Number of cylinders (indicating that there are several tracks on each disk, the general total is 1024) Number of heads (indicating the number of disks) Number of sectors (indicating how many sectors each track, generally the total number is 64) Sectors (storage basic unit, the size is generally 512B 4KB).

2. Memory capacity: The amount of memory is equal to the sum of the capacity of all memory modules inserted into the memory slots of the motherboard, and the upper limit of the memory capacity is generally determined by the chipset and memory slots of the motherboard.

Third, the characteristics are different.

1. Hard disk capacity: measured by bytes (B, byte), kilobytes (KB, kilobyte), megabytes (MB, megabytes), and gigabytes (GB, gigabytes).

2. Memory capacity: The larger the memory capacity, the more conducive to the operation of the system.

There is no difference between the capacity calculations of memory and hard disks, but they are used in different ways. Data in the memory is lost when the computer is shut down or the power is lost, while the data in the hard disk can be saved after the shutdown.

Computer (computer), commonly known as computer, is an electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed. It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

Inventor of the computer John von Neumann. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.
