What is the meaning of memory capacity G ?

There is also 1TB = 1024GB

The carry is 2 to the 10th power.

Reference: The base system in the computer is calculated according to the binary system, and the unit of capacity is b (byte, byte), for example, we say that the capacity of a hard disk is 40G, which means 40GB.

G is the first letter of the English word giga (billion). Smaller than g are m (mega, million, trillion), k (kilo, thousand), and t (tril, trillion) is larger than g, and the conversion between them is like this.

1t=1024g

1g=1024m

1m=1024k

1k=1024b

b (byte, byte) is the most basic unit of measurement in the computer, and b (bit, bit, note the difference between this b and uppercase b), b (bit) is the smallest unit in the computer, 1b = 8bAn English letter or number occupies one byte of space in the computer, and a Chinese character occupies two bytes (called a character), that is, 1 character = 2 bytes.

Some people may not know why 1024 is used as a conversion number, according to conventional mathematics, 1t = 1000g, 1g = 1000m...This is also determined by the binary rules in the computer, 1024 = 2 10 (2 to the 10th power), in binary there are no numbers of 100, 1000, 10000 in the power of n, only 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024....Of these, only 1024 is the closest to 1000.

Therefore, the number 1024 was chosen as the conversion between units.

The above is about the capacity of the hard disk, and the same is true for the memory capacity. In addition, there is speed, our usual CPU speed, memory speed is based on ordinary mathematics in 1000 as the conversion unit. That is, 1t = 1000g, 1g = 1000m, and so on.

However, the unit is not bytes, but hertz (Hz).For example, let's say that the speed of a CPU is, that is, the frequency of this CPU is.

1KB = 1024 bytes, 1MB = 1024KB, 1GB (gigabyte) = 1024MB

And when buying a hard disk or other storage device, it is indicated that 1GB = 1000MB, 1MB = 1000KB, and so on.

GB - Gigabytes.

mb - megabytes.

kb - kilobytes.

b -- bytes.

bit – a bit, a binary bit, such as 0,1.

1b=8bit

1kb=1024b

1mb=1024kb

1gb=1024mb

Well, that's 1GB=1024MB 1MB=1024KB 1KB=1024bit

This is the Windows algorithm for carrying, but this algorithm cannot be applied to the hard disk, because the hard disk is calculated like this: 1GB=1000MB 1MB=1000KB=1000KB, so we always look at the hard disk on the Windows system, and when you look at the operation, you have to look at what it is used for.

In the same way, G is a shorthand for GBGB, also known as gigabyte (GB, gigabyte, also known as gigabyte or gigabyte or gigabyte or halberd in China), often abbreviated as G, is a decimal unit of information measurement. Gigabytes are often confused with gibibytes, the binary unit of measurement for information. It is often used to indicate the storage capacity of storage media with large capacity, such as hard disks and storage.

Conversion rate Computers are binary, let them calculate units, only the integer power of 2 can be very convenient for computer calculations, because the internal circuits of the computer work in two states: high level and low level. So the signal is represented in binary so that the computer can recognize it. People are accustomed to using the decimal system, so memory manufacturers use 1000 as the advance rate.

The consequence of this is that the actual capacity is less than the nominal capacity, but this is legal. 1024 is 2 to the 10th power, because if it is larger, it is not close to the integer power of 10, which is inconvenient for people to calculate; Take small, the advance rate is too low, and the units need more to meet the demand, so take 2 to the 10th power.

It's the same meaning, G is just a shorthand for GB, 1GB = 1024MB1MB=1024KB1KB=1024B

Hehe, the simple way of writing is suitable for those of us who are lazy.

1. Introduction to memory fusion technology

What is Content Convergence Technology?

Memory fusion technology is the fusion of memory and flash memory. Let's take a look at common semiconductor memory, which can be divided into read-only memory, ROM and random memory according to the read and write function.

RAM, see the brain map below for a detailed breakdown.

RAM random access memory is a kind of volatile memory that can be read and written, characterized by fast speed, but when the power is off, the stored content will be lost, and it needs to be constantly refreshed, mainly used to store data for a short period of time, and used as a dynamic buffer when the system is running. ROM read-only memory, which is a type of non-volatile memory.

Information can still be saved after power failure, that is to say, once the Xunchang data is written, it will be fixed, even if the power is cut off, the stored data will not be lost, and the read and write speed is relatively slow for RAM. It is mainly used to store large data, such as **, audio high-index, **, etc. Usually what we call memory (also called memory when there is time) refers to the DDR SDRAM in the mobile phone, and the flash memory is NAND flash.

Memory fusion technology is to expand part of the flash memory to memory use. In fact, as early as the Android era, there were two major memory optimization technologies, ZRAM and SWAP. <>

The ZRAM principle is to combine physical memory.

, compress the inactive part of the application, and decompress the data when needed, the core is memory compression. The disadvantage is that it will increase the CPU load slightly, requiring additional CPU calculations and screening for inactivity**. Swap is similar to the virtual memory of Windows.

The technology is to use the ROM as RAM when the memory is low. It allows the system to run more programs at the same time, but the disadvantage is that the read and write speed is lower than the memory, and this repeated erase and write of the flash memory will reduce the flash memory life to a certain extent. <>

2. Advantages of memory fusion technology

The Android system is a big eater of memory, and the size of the memory directly affects the performance of the system, and the most direct experience for users is fluency. The larger the memory, the more apps can be opened at the same time, and the faster the switching between different apps will be. Memory fusion technology is to use a part of flash memory as running memory.

to enable more apps to be opened on your phone at the same time. Due to the different manufacturing processes, the unit price per GB of DRAM chips used in memory is much more expensive than that of NAND flash memory, so mid-to-high-end models are usually 8GB and 12GB, and low-end models are more based on 4G and 6GB. Through memory fusion technology, the memory space can be greatly increased, and the experience of low-end users may be more obvious, and mid-to-high-end users will also be improved to varying degrees.

The specific degree of improvement depends on the system memory expansion ability of each mobile phone factory, and depends on the debugging ability of the software.

G and GB are the same size. In fact, G and GB are the same unit, and G is nothing more than an abbreviation for GB.

In fact, the system recognizes memory in bytes, and each byte is composed of 8-bit binary numbers.

composition, that is, 8 bits (bits, also known as "bits"), according to the binary method of the computer, 1byte = 8bit; 1kb=1024byte；1mb=1024kb；1gb=1024mb；1tb=1024gb。

Byte, byte, is a unit of measurement used by computer information technology to measure storage capacity.

Typically, one byte equals eight bits and is used in some computer programming languages to represent a data type.

and language characters, data storage is in bytes, and data transmission is mostly in "bits", that is, bits, also known as "bits" as units, a bit represents a 0 or 1, that is, binary, every 8 bits "bit, abbreviated as b" to form a byte, is the smallest level of information units.

Memory is one of the important components in the computer, it is the bridge to communicate with the CPU, and all the programs in the computer are run in memory, so the performance of the memory has a great impact on the computer.

The memory capacity of a computer usually refers to a random memory memory.

RAM) is a memory module.

The key parameters, the capacity of the memory is generally 2 to the power of the whole, such as 64MB, 128MB, 256MB, etc., generally speaking, the larger the memory capacity, the more.

In the early 21st century, the mainstream memory capacity in desktops was 2GB or 4GB, while 512MB and 256MB memory were less used.

Memory 1G is the capacity of the computer to store data, 1GB is referred to as 1G 1G = 1024MB, 1MB = 1024KB, 1KB = 1024 bytes.

Memory (is the internal memory that exchanges data directly with the CPU. It can be read and written at any time, and it is fast, often as a temporary data storage medium for the operating system or other running programs.

Memory is a storage space that can be directly addressed by the CPU and is made of semiconductor devices. Memory is characterized by fast access rates. Memory generally uses semiconductor memory cells, including random access memory (RAM), read-only memory (ROM), and cache.

1. The memory capacity of a computer usually refers to the capacity of random access memory (RAM), which is the key parameter of the memory module. The capacity of the memory is generally to the power of 2, such as 64MB, 128MB, 256MB, etc., generally speaking, the larger the memory capacity, the more conducive to the operation of the system. At the beginning of the 21st century, the memory capacity of the mainstream local chop in the Taiwan code lap elimination machine is 2GB or 4GB, and the memory of 512MB and 256MB has been rarely used.

2. The system recognizes memory in bytes, and each byte is composed of 8 binary numbers, that is, 8 bits (bits, also known as "bits"). According to the binary method of the computer, 1byte = 8bit; 1kb=1024byte；1mb=1024kb；1gb=1024mb；1tb=1024gb。

G and GB are the same single position, so G and GB are the same size.

Gigabyte (GB, Gigabyte, also known as Gigabyte or Gigabyte or Gigabyte or Gigabyte or Gigabyte in China)) is a unit of 10-base storage capacity, and GB is often abbreviated as G.

Capacity Unit Conversion.

1gb = 1,000mb;

1gb = 1,000,000kb;

1gb = 1,000,000,000b。

What exactly does 4G mean and how fast the internet is, do you know?

CPU is the first processor, and most of the data processed by the computer when working should be the data stored in the hard disk. But the capacity of hard drives is too large today (now it has reached tens or even hundreds of gigabytes).

The CPU is inconvenient to find and run, resulting in memory.

The principle is to transfer the data to be processed by the CPU to memory, and then the CPU processes the data in memory. Because of the small memory capacity, it is convenient and fast to process. That's why memory is much smaller than hard drives.

Since memory is where the data processed by the CPU is stored, of course, its capacity is consumed. When some data stored in memory is being processed by the CPU, the remaining part of the memory space that is not occupied is the available memory.

This computer is very good, and most of the single-player games are stress-free.

4GB is 1000 QAQ of SKE48 songs with 4MB (ignore me).
