Ask the master to explain what storage and memory mean

Storage is the phone memory card Memory is the phone's own memory Hopefully.

After reading "Insects", this book fascinated me very much, it turns out that there are so many mysteries in the insect world, I know: how cicadas shed their shells in the early morning; how the dung shell mantis rolls the dung ball; How ants eat aphid secretions. Also figured out:

The "son of the moth" is wrong, the bee catches the green worm not as its own son, but arranges food for its offspring.

The first time I read "Insects", somehow it attracted me. This is a popular science book describing the fertility, labor, hunting and death of insects. The humorous narrative is hilarious ......What a strange and interesting story of the humanized bugs! Fabre's "Insects" made me feel no dream, and those specific and detailed words made me feel the presence of magnifying glasses, dampness, stars, and the smell of insects from time to time, as if I was in the scene.

I've been ignored for too long.

5) Reflections on "Insects".

After reading "Insects", this book fascinated me very much, it turns out that there are so many mysteries in the insect world, I know: how cicadas shed their shells in the early morning; how the dung shell mantis rolls the dung ball; How ants eat aphid secretions. Also figured out:

The first time I read "Insects", somehow it attracted me. This is a popular science book describing the fertility, labor, hunting and death of insects. The humorous narrative is hilarious ......What a strange and interesting story of the humanized bugs! Fabre's "Insects" made me feel no dream, and those specific and detailed words made me feel the presence of magnifying glasses, dampness, stars, and the smell of insects from time to time, as if I was in the scene.

The figures of the insects, which I had ignored for too long, and their arrogant chirping, gathered at once, and I held my breath, and then, with them, penetrated the darkness of my mind. It was Fabre who made me see the striking similarities between insects and us humans on many issues of life and death, labor and plunder. "Insects" is not a world created by a writer, it is different from **, they are the most basic facts!

It was every day and every night of Fabre's life, alone, quiet, almost isolated from the world of loneliness and hardship. I raised my head, and at this moment, I really wanted to raise my head and look up at the stars to deal with the mystery of the existence of insects. It introduced me to a vivid world of insects for the first time.

The storage is for the body, and the memory is for the memory card.

Internal storage refers to the storage space built into your phone or computer device.

Internal storage refers to the storage space built into a mobile phone or computer device, which is usually used to store the user's applications, data, documents, etc. On the other hand, external storage, such as SD cards, USB flash drives, and other removable storage devices, needs to be plugged into the device before it can be used. The size of the internal storage is usually fixed, and the sliding mode is generally determined at the time of purchasing the device, while the external storage can be expanded by replacing or adding memory cards, etc.

Path to internal storage:

Internal storage may have different paths on different operating systems and devices, the following are the internal storage paths of common devices

1. Android system:

storage emulated 0 or sdcard for sliding sails.

2. iOS system:

3. Windows system:

4. macOS system:

Memory is a kind of memory, memory is the place where programs and data are stored, for example, when we use WPS to process documents, when you type characters on the keyboard, it is stored in memory, and when you choose to save, the data in memory will be stored in the hard (magnetic) disk.

Briefly describe the difference between internal memory and external memory: different meanings, different functions.

First, the meaning is different:

Internal memory is the direct place where the CPU and external devices exchange data, and the internal memory is second to the CPU speed, but it is also a high-speed storage device, which includes RAM, video memory, and some cache.

External memory is an external storage device, which is much slower than the memory key, but can store data such as hard disks, CD-ROM, flash memory, etc. for a long time.

Second, the role is different:

One has a time advantage (memory), fast speed, but small capacity, and is not retained after power failure, and the other has a space advantage (external memory), large capacity, and can keep the manuscript quietly for a long time. The CPU can only access the memory directly. External storage has to go to memory before the CPU can handle it.

The inside and outside are not distinguished based on whether they are in the chassis or not. What the CPU can directly access is called memory.

Read-only memory (ROM).

ROM stands for Read Only Memory, and when a ROM is made, information (data or programs) is stored and stored permanently. This information can only be read out, generally not written, and this data will not be lost even if the machine has a power outage.

The most popular read-only memory is Flash Memory, which is an upgrade of EEPROM (Electrically Erased Programmable Read-Only Memory), which can be erased repeatedly by electrical principles. Most of the BIOS programs are now stored in the FlashROM chip. USB flash drives and solid-state drives (SSDs) are also made using the principle of flash memory.

Memory is an important part of a computer, also known as main memory.

The role of memory is to temporarily store programs and data so that the CPU can access them quickly. Memory is the main memory in a computer, located between external memory (such as a hard disk) and the CPU, and is a buffer in the computer.

Memory is made of semiconductor devices, and it can be divided into two types: RAM (random access memory) and ROM (read-only memory). RAM is readable and writable memory, which can store running programs and data. When the computer is turned off, the data in the RAM is lost.

A ROM is a special type of memory that can only read data, not write it.

The memory cells of memory are addressed in bytes, i.e., each memory cell has a unique address. The CPU accesses a key in memory through the address bus, which refers to a storage unit, and reads or writes data through the data bus. The read and write speed of memory is much faster than that of external memory, which is also an important performance indicator of a computer.

Memory size:

The type of memory and how often it runs will have an impact on performance, but capacity will have a greater impact on the scale. All else being equal, the higher the memory, the higher the performance of the machine. The ** of memory is slightly lower, around 2011, the configuration of computer memory is getting larger and larger, generally above 1G, and there are more 2G, 4G, 6G memory computers.

As one of the important accessories in a computer, the size of memory capacity can be directly related to the performance of the entire system. As a result, memory capacity has become more and more of a concern for consumers. Especially at present, the Win7 operating system has begun to replace the XP draft, for the latest Win7 operating system, most consumers think that large capacity can improve its memory score.

How memory works. Functionally, we can think of memory as a bridge between the memory controller and the CPU, and memory is equivalent to a "warehouse". Obviously, the capacity of memory determines the size of the "warehouse", and the speed of the memory determines the width of the "bridge", both of which are indispensable, which is what we often call "memory capacity" and "memory speed".

In the PCMark Vantage test, you can see that the memory performance of 2GB and 4GB DDR3-1600 is relatively close, of which 2GB memory is only lagging behind when starting some office software, after all, it is less than half of the capacity, so it is difficult to run.

In the 3DMarkVantage game performance test, we can see that under the Win7 system, the performance difference between 2GB and 4GB memory is not very big, and the results are very close. At the same time, in the Win7 environment, the difference between 2GB memory and 4GB memory is very small, and in some cases there is no difference, so if you want to improve memory performance, it is not very meaningful to just think about upgrading capacity.

This is a special term for computer science, in fact, it is the storage space of pure sensitive memory, this memory it refers to a tool used to destroy pants and store information, that is to say, the file program in the computer needs to be similar to our physical object, put in one place, it is a semiconductor device, is a place to temporarily store programs and data.

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。

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.

Storage 1. Storage, accumulating money or things. "Qing Huidian Case, Household Department, Treasury": "The Household Department Treasury is empty, and the money should be stored.

Qing Huidian, Hubu Cangchang Yamen, Shilang Job": "Every year, the new Cao enters the warehouse, and the warehouse determines the amount of rice of various colors stored in the warehouse, and the number of beige stored in a certain year is stored in a warehouse, and the record is filed in advance of the consultation department. Lu Xun's "Collection of Letters: To Li Xiaofeng":

The family of the author of "The Death of the Old Times" is now quite embarrassed, and several friends have collected money for it to store for their children's reading. ”

2. Refers to the accumulated money or things. Sha Ting's "Doctor": "Even if he occasionally thinks of his own evening scene, and thinks that he doesn't have much storage, he can sigh and throw it away." ”

3. Storage is to save data to certain media in a reasonable, safe and effective way according to different application environments and can ensure effective access, generally speaking, it can contain two meanings: on the one hand, it is a physical medium for data to reside temporarily or for a long time; On the other hand, it is the way or behavior that guarantees the integrity and security of data.
