The computer hard disk is formatted, how can there be dozens of MB of memory?

The function of memory is not the same as that of a hard disk.

The function of a hard drive is to store things, and it has little to do with how fast or slow the computer runs.

Memory is different. To put it simply, when running a program, the system has to put it in memory so that it can be ready at any time, and it is conceivable that if the system has a large memory, then it has a larger buffer space, and when running a large program and more programs at the same time, the speed can be significantly faster.

So if you want to upgrade your computer while maintaining the current configuration, adding memory is undoubtedly the most basic.

System partition files, no matter how you delete them, are just hidden files.

If you turn off the system virtual memory first, you should be fine.

1GB = 1024MB, 1MB = 1024KB in Windows; In Linux and Mac, 1GB = 1000MB, 1MB = 1000KB, and the hard disk is produced using the Linux computing method! Take your time and do the math yourself!

g=1024mb。

g=1gb=1024mb=1024m。

t=1024g，1m=1024k。

4. Hard disk is one of the main storage media of the computer, which is composed of one or more aluminum or glass discs. The disc is covered with a ferromagnetic material. Hard disks include solid-state drives (SSD disks, modern hard disks), mechanical hard disks (HDD traditional hard disks), and hybrid hard disks (HHD is a new hard disk born based on traditional mechanical hard disks).

SSD uses flash memory particles for storage, HDD uses magnetic disks for storage, and hybrid hard disk (HHD) is a kind of hard disk that integrates magnetic hard disk and flash memory. The vast majority of hard drives are fixed hard drives that are permanently sealed and fixed in the hard drive.

In order to provide more memory capacity than the actual physical memory for use, the Windows operating system takes up a portion of the space on the hard disk as virtual memory. When the CPU needs it, it will first read the data in memory. When the capacity of the running program exceeds the memory capacity, the Windows operating system writes the data that needs to be stored temporarily to the hard disk.

So, the size of the computer's memory is equal to the actual physical memory capacity plus the size of the "paging file" (i.e., the swap file). If needed, Paging Files uses all available space on your hard disk.

If your system virtual memory is too low, you can right-click on "My Computer" and select "Properties Advanced Performance Settings Advanced Open Virtual Memory Settings", you can reset the maximum and minimum values, add values by multiple of the physical memory, or change the storage location of the virtual memory, and set it to other hard disk partitions with larger capacity, so that the system virtual memory has enough space and makes the system run faster.

There are three solutions to virtual memory that is too low:

1.The capacity of the custom virtual content (automatic by default) is too small and can be re-sized.

2.The disk where the system is located (usually the C drive) has too little free capacity and the running program is large, and the virtual memory is usually created in the system disk directory by default.

1gb=2＾10mb=1024mb

1mb=2＾10kb=1024kb

1kb=2＾10b=1024b

1b, that is, a byte, is usually used to represent the size of the file, a half-width letter and number occupy one byte, and a Chinese character or full-width symbol points two bytes.

1b＝8bit

bit, that is, a word bit.

For hard disks, this is the theoretical standard for calculating the old capacity of the computer, but the manufacturers calculate it according to 1000 instead of 1024 when it is produced, so the declared capacity is smaller than the actual capacity. (Know that the operating system is calculated by standard).

Each Chinese character occupies 2 bytes, so 80GB can store 80 1024 1024 1024 2 = 42,949,672,960 Chinese characters, about 40 billion.
