How much memory is actually marked as 8G?

In Microsoft's Windows system, 1GB=1024 MB, but the conversion unit of hard disk and memory manufacturers is 1GB=1000MB8G * 1000 MB = 8000 MB8000 MB 1024 MB = GB In fact, in terms of capacity, there is still a part of the USB flash drive system to occupy. Therefore, the usable capacity of an 8G USB flash drive is about that.

It must be noted that the labeling of the size of the memory module is accurate, and the labeling of peripheral storage devices such as USB flash drives, mobile hard disks, etc., will have the so-called unit conversion problem.

In computers, the base system of B KB MB GB TB is 1024 = 2 to the 10th power, but the base system of peripheral storage equipment manufacturers is 1000, the purpose is self-evident, it is to reduce costs.

However, if the size that can be recognized by the memory module does not match the label, one is that the memory module itself is faulty, but the operating system: due to addressing reasons, the 32-bit operating system cannot fully utilize the memory of 4G and above. If you want to make full use of the extra memory capacity, you should install a 64-bit system.

Windows XP is 64-bit, but the 64-bit version of XP does not have native Chinese, so it is not recommended.

In addition, the integrated graphics card in the machine will also allocate a part of the memory for video memory, and there will also be a problem of "shrinkage" of available memory.

Basically, the number of marks is as much as it is, but there may be damage in the use of memory modules, resulting in a decrease in the actual value, and there is also a problem with the shared memory usage of the graphics card.

Memory capacity of individual manufacturers = Labeled value

8G is enough for the case of not playing 3A masterpieces.

Video memory, also known as frame buffer, is used to store render data that has been processed or will be extracted by the graphics card chip. Like a computer's memory, video memory is the part that is used to store the graphic information to be processed.

Like a computer's memory, video memory is the part that is used to store the graphic information to be processed. The picture we see on the display is made up of individual pixels, and each pixel controls its brightness and color with 4 to 32 or even 64 bits of data, which must be saved through video memory.

The difference between video memory and memory on a computer

1. The work object is different: the video memory is the temporary storage data for the GPU; If you are using an integrated graphics card, that is, the system does not have a separate video memory, and the memory space is divided in the memory space.

2. Different storage speeds: taking GDDR6 video memory as an example, the speed can reach up to 72GB S; And the speed of DDR4 memory is:

3. Different capacities: The memory capacity is fixed, and the capacity configured by the graphics card manufacturer is the upper limit, and consumers cannot add it by themselves; The memory of consumer computers is based on DDR slots, and the memory capacity can be increased or decreased according to the demand and the number of slots on the motherboard.

8G memory refers to the memory module plugged into the motherboard of the computer, the storage capacity is 8G, and the memory module can also be unplugged from the motherboard. Memory modules are used for temporary storage of data exchange while the computer is running.

1g=1024m=1024*1024k=1024*1024*1024byte

8G running memoryThe mobile phone is working normally and there is about G storage space, but it should be noted that after the mobile phone is working normally, how much is left in the 8G running memory is related to the background software opened by the mobile phone, if the software is larger or the software running is more, then the remaining running memory of the mobile phone will be relatively less.

The budget is about 8000k, that is, about that, but the actual amount is definitely lower, which is reasonable.

Here's how it works:

8*10^6/(8*1024*1024)*8g =

But there are some system files in each USB drive (around 100 megabytes), so the 8G USB drive is actually around.

G is the abbreviation of GB: 1TB=1024GB1GB=1024MB1MB=1024KB1KB=1024BMhe market says 8G memory card, but it can't really reach 8G, which is more than 7 points at most, you plug your memory card into the computer, right-click on the property, you can see how big your memory card is.

It's not video memory, it's computer memory.

Memory is one of the most important components of a computer, and it is the bridge that communicates with the CPU. The running of all programs in the computer takes place in memory, so the performance of the memory has a very large impact on the computer. Memory, also known as internal memory, is used to temporarily store computing data in the CPU and exchange data with external memory such as hard disks.

As long as the computer is running, the CPU will transfer the data that needs to be calculated to the memory for calculation, and when the operation is completed, the CPU will send the result out, and the operation of the memory also determines the stable operation of the computer.

Memory is made up of parts such as memory chips, circuit boards, gold fingers, etc.

If the video memory is insufficient, a part of the computer's memory will be shared. For example, 512M video memory, 512M shared memory, so that the video memory reaches 1G.

In most cases, 8G of RAM is enough with only 4G of it.

1. Ordinary home users: 4GB of memory is enough. The rest is automatically used as a disk cache to effectively improve the read and write speed of the disk.

2. Game lovers: At present, the maximum memory demand for games is 6GB, so game lovers can basically use enough 8GB memory. If the memory is too small, the game will not be allowed to run.

The memory capacity of the computer is 8G, which means that the size of the memory capacity is 8GB, that is, the maximum data that can be stored in the memory is 8GB.

The memory module is used for temporary storage of data exchange when the computer is running, 8G memory is inserted into the memory module on the motherboard of the computer, the storage capacity is 8G, and the memory module can also be unplugged from the motherboard.

Computer memory refers to the runtime memory, and 8GB refers to the size of the computer's memory.

Computer memory is equivalent to mobile phone running memory, and computer hard disk is equivalent to mobile phone memory card.

1. That is, the total memory capacity in your computer is 8G, which means that your computer memory is sufficient, which can fully meet all your usual work without worrying about insufficient memory. 、

2. Memory refers to the internal memory, which is characterized by fast access rate, is the main component of the computer, it is mainly used to temporarily store data, such as the data called in the computer, it needs to be read from the hard disk, sent to the memory, and then the memory is sent to the CPU, which can also be understood as the cache between the memory and the CPU.

Just like the principle of a memory card, 1000MB is 1G
